Why waste water treatment is important for our environment | Chokhavatia Associates

The surrounding of our houses and workplaces are our environment.

We have to take the responsibility to keep our environment safe and prevent it from pollution. Our environment can be in great danger if we are not taking proper precautions through wastewater treatment before it can be released back into the environment. Drastic efforts like depletion of fishes, water habitat and eradication of species are some of the common hazards caused due to environmental pollution. Let’s see some of the waste water treatment in India and how it can be safely released back to the environment for a healthy habitat.

What is waste water?
If you are curious about how the waste water is treated, before that, you might actually need to know what this waste water is really. Waste water is the water that drains from the kitchen sinks, baths, showers, toilet and industrial waste. This waste water is collected in big tanks for the process of segregating waste materials. Once the water is collected in huge tanks, the solids and waste substances settle down in the bottom, while the oil and fat substances float on top of the water.

Waste Water Treatment
The waste water goes through a series of steps before the harmful substances are completely removed from them. Sludge is formed after the waste water is left to remain in huge tanks. This sludge is removed for further treatment to make it harmless to the environment. The water is moved to secondary waste water treatment process for further processes.



During the next process, micro organisms are introduced into the tanks to decompose small elements that remain in the base of the waste water. It is also aerated with oxygen for cleansing process. The sludge that remains in the bottom is scraped and removed while the left over waste water is moved to tertiary treatment.

During the last level of waste water treatment harmful chemical substance like nitrogen and other are removed from the waste water. Once the waste water is designated to be environmentally safe it is then drained into rivers, water irrigation and agricultural lands.

Environmental Hazards

Talking about the environmental hazards, if the waste water is not treated properly it can lead to dissolved oxygen levels that affect the habitat of fishes and other aquatic life.
  • Excessive levels of chemical substances like nitrogen or phosphorus can be poisonous, deplete oxygen level and affect marine life.
  •  Further, chemicals like chlorine can be harmful to invertebrates like algae and fish.
  •  Bacteria and viruses can cause severe damage to life inside water, reduce human recreation, water consumption & consuming shell fish.
  •  Certain metals like mercury, cadmium and lead can have high degree of toxic effects to water species. 
  •  Pharmaceutical and daily use personal products that enter into the environment can cause human health effects, threats to aquatic life and wildlife
  • The wastewater treatment in India successfully removes the contaminants through a series of process. The end process consists of water that is free from chemical and microorganisms and is considered to be environmentally safe. The water is drained into water bodies like rivers, irrigation or agricultural lands for use.

Wastewater Treatment plant – How it works?

Waste water needs treatment. Otherwise it can pollute your environment easily. Pollution can further lead to health issues, depletion of marine habitat, etc. For the most part, our environment can manage itself in recycling the water resources. However, it can handle only up to a certain extent. That is why, it is essential to process the water in waste water treatment plant to remove the pollutants and save the environment.

RO Water Treatment
There are several waste water treatment plants that are designed for a particular purpose. The RO water treatment plant is used to treat the water for drinking purposes. It utilizes the reverse osmosis process for cleansing the water and removing unwanted particles. It operates in a sustained pressure mode until all the water is passed through the device.

Demineralised Water Treatment Plant
The demineralised water treatment plant removes the minerals from the water through the process of ion exchange. Demineralization goes through the process of distillation, deionization, membrane filtration, electro dialysis and other technologies. As most of the content in water are salts, the process of deionization can produce pure water after all the chemical substances is absorbed. It is often the proven system of water treatment to produce pure water for consumption.

Waste Water Treatment Plant
The waste water need to be treated in plants before they can be disposed into the environment. They carry harmful substances that have the effect to deteriorate the environment. These harmful substances need to be treated in wastewater treatment plant to be purified and made suitable for land use. We live so close to the water, therefore it is highly essential that water is treated for hygienic reasons. It can preserve the environment, keep the fishes from dying or spoil a recreation area.

The waste water goes through a series of steps before it is completely free from pollutants and ready to be discharged. First of all, it is allowed to settle in large tanks, where the solid waste gets settled in the bottom of the tanks. These waste also called as sludge is removed and sent for further processing. The water is transferred to the next step of water treatment process.

Disinfectant
Chemicals like chlorine are added as a disinfectant to remove the second level of pollutant from the water. The dosage of chlorine depends on the amount of pollutants in the waste water, dosages of 5 to 15 milligrams per litre is common. The bactericidal effects of chlorine are highly dependent on the pH value, contact time, effluent temperature and organic content.

The water treatment consultants play a pivotal role in planning a water resource requirement for a business house. Whatever may be the requirement they can provide a solution that is environmentally safe and meets their requirement perfectly. The water treatment consultants have the knowledge and expertise that can help a business or an industry to plan their water supply and ensure that it is sufficient for their use.

Through the process of RO purifier, demineralization and adding chlorine disinfectant the polluted water is turned into pure water that is safe for consumption or to be used for land or irrigation purpose.

Sewage Water Treatment Process | Chokhavatia Associates

Sewage water needs to be treated in the sewage plant before it can be drained into the environment. Careful measures need to be taken. If not, it can lead to harmful effects in the environment. Health issues, water pollution are some of the problems that are caused by the sewage water if not treated properly.



The sewage is the waste water that is collected from wash basins, toilets, baths, washing machines and industrial waste. They are treated through a series of steps until it’s treated and finally drained back into environment when it’s considered to be safe.

Screening
Screening is the initial process in sewage water treatment. The sewage system makes use of the septic tank that collects and stores the sewage water. The solids settle down and the remaining water is sent downstream for processing through 6 inch to 4 inch pipeline. Such a process is called a decentralized system where every house’s sewage is treated in separate septic tanks.



During the screening process, large objects like diapers, tampons, sanitary items, face wipes, plastics and rags are removed to prevent from any blockage in the downstream to the sewage plant. Items like grit are removed using special equipment that gets washed away into the sewer.

The sewage water treatment can use the gravitational force to get to the sewage treatment plant. In-case if the pipeline excavation is not possible due to hard rocks or any other reason, the sewage water need to be pumped into the pipeline right to the sewage treatment plant. The pipeline measurements range from 6 inches up-to 30 feet of well built concrete tunnels.

Primary Treatment
During the primary treatment, solid waste (human waste) is separated from the waste water and sent to be treated. The wastewater is collected in large settlement tanks, where the solid waste gets settled leaving the water on the surface level. There is also fat that rises to the top and form a crust. The liquid in-between the solids and crust is sent to secondary treatment whereas the solids and the top layer of crust are sent for further treatment periodically.

Secondary Treatment
The water from the primary treatment is placed on large rectangular tanks. Now, oxygen is supplied into this process to encourage the growth of bacteria. The bacteria break the tiny bits of sludge that might have escaped during the previous treatment. It also reduces other pollutant and detergents that might still be mixed with the waste water.

Final Treatment
In this process, the waste water is passed into a settlement tank. Excess sludge is formed again due to the bacterial action. This sludge is repeatedly scraped to remove from the water. Once the sludge is removed, the water is free from pollutants. The water at this stage is completely free from any kind of harmful physical or chemical substance, and it is free to be drained into the river.

The waste water goes through several stages in the sewage treatment plant to make it safe for the environment. The water is thoroughly treated until they make sure that it is clean and pollutant-free before discharging it to the water bodies. One more important factor for screening the sewage water is to prevent any diseases that may be caused due to bacteria, virus or any organisms.

Practices Adopted by Consultants of Environmental While Framing Solutions

Once hired by the enterprises and industrial establishments Consultants of Environmental Solutions, make sure to make all arrangements, so that their patrons can run their business interests profitably; and too without being penalized by the law enforcement agencies for the activities taking place in their premises. Usually, once engaged by the patrons, these consultants initially, do an Environmental Site Assessment; i.e. optical evaluation as well as the document scrutiny of the targeted landed assets besides the immediate surrounding area is been performed. The purpose of such performing such actions is to detect would be environmental concerns besides to determine whether such type of inspections is required or not.

Visual inspection of the property and a complete check of the written documents cannot reveal the complete environmental history; and the state of earth can only be determined after conducting relevant investigations. An expert consultant knows which type of investigation is required, and this depends upon on the nature of services he is providing to his or her patrons. An EM mapping on trivial basis gives enough assistance to consultants regarding visual assessment of the area concerned. Such an action can lead to cracking important information about the past activities taken place in the area, thus, consultants can lay down their plan accordingly. This is indeed a cost effective measure, as any leakage in past can make soil infected, and so the solution provider can take necessary steps in accordance to the environment protection; and with this action their clients are protected from possible legal action my law enforcement agencies.

With introduction of geophysical hardware and software in the market has made work of these consultants and geophysicist easier; on one hand it works faster and on other hand uses minimal manpower, turning entire project cost effective.

Magnetic or G radiometer Mapping

 Practiced since a considerable period by environmental Consultants, magnetic mapping has its own importance in exploring possible actions taken in past, through which water, soil or any other natural resource is been polluted. Naturally, if precaution is taken while deducting the problems prior to start of project will help enterprises in erecting them. As a result, further deterioration is being avoided.
When it comes to soil detection and monitoring searching, environmentalists and consultants take help of a number of instruments, and thanks to the advancement of technology, newer and innovative set of mechanisms is being introduced. Through these technologies, resistivity and seismic surveys are being organized, thus the industries can deduct groundwater pathways found in deep inside ground. The bed rock fractures as well as cavities underground; and there are certain industries whose activities will definitely effect due to such happenings.

With growing industrial activities, and strict international environmental laws requirement of Environmental consultants is increasing every day. It is through their expertise they help industries of all order in establishing their businesses and that too with in legal framework. Environmental Consultants in India Are known for their dedication and teamwork, thus are most sought when compared to their counterparts

Plant of Sewage Treatment Making Contaminated Water Reusable

Treating water is an engineering practice that assists water to return resume to its natural state; as a result of which it is suitable for usage as per requirement. When it comes to activities that are taken in all set of industrial sectors, it is often observed that there is lots of consumption of water. Fresh water consumption for ongoing activities is not a wise decision; and this is the reason, water that has been used after commercial and domestic activities is usually treated and after that disturbed to the concerned industry again and again for all sets of uses. Most of the industrial sectors have started hiring services of consultants having expertise in Plant of Sewage Treatment; and these experts through their expertise provide services that consists of testing and chemical or biological treatment whatever required so that water is utilized efficiently.




Cooling Towers found in industries are open systems and they have a high risk of getting affected with viruses. Water found in these towers is by and large warm during solstices season, and this gives enough reason for bacteria breeding. As this water is exposed to environment and in case it is not treated, there is a possibility of environmental issues in surroundings; as a result, renders adverse effect on human health. However, prior to giving treatment, it will be better to understand the level of bacteria involved, and it can be achieved by performing a proper test. Once the testing is steered by experts, it will be easier from them to conjure about the type test required i.e. between chemical or biological treatments or both. Enterprises and facilities who do not conduct such investigations have a tendency of leaving behind biocide in the systems. And leaving behind traces of chemicals or toxins is detrimental to systems.


Establishments that arrange for industrial treatment for water all the time render their patrons with economical and cost effective consultation while taking up a project. These solution providers ensure that their customers get ample information about heating and cooling systems; and along with the required information the chemical courses obligatory to treat water.

When it comes for annual maintenance cost, it is the mutual understanding between service provider and the enterprises through which it can be bargained. And with the help of experts the analysis of the plant can be done throughout the time frame. In short, water system maintenance proves to be beneficial for the environment as well as enterprises.

Water treatment plants habitually have a high corrosion rate; and if not effectually scrutinized can leave behind heavy maintenance and repair costs. Repair and maintenance at regular intervals will Definitely, give an adverse effect on monetary grounds. In this regard, solution providers do render corrosion testing and evaluation services. There are various testing methods and few of them are inexpensive, within reach of most of enterprises. These are tested means that can help enterprises in maintaining treatment plants located in their premises.

How Does Treatment of Plant of Wastewater Helps

Plant of Wastewater Treatment treats and recycles effluents and polluted water so that it can be reclaimed for further use. Water is an element which is been used for variety of purposes, and the Untreated water which is discarded after usage holds a high level adulteration and pollution along with variety of bacterial elements. This water when drained into nature destroys and even pollutes water reserves. Due to oodles of activities and expansion in population, our universe is already facing shortage of clean and fresh water stocks for day to day use. Keeping this in mind, untreated water needs to be filtered so that it can be re-used.



There are a number of modes through which industrial and even residential wastewater can be purified, as realms are now instituting innovative ways to clean home and industrialized wastewater individually. Here, in this piece of writing you can glance upon some of the general processes adopted in cleaning effluent water and how does these procedures help environment.

Primary Treatment:
In wastewater treatment, the polluted water undergoes a number of processes, in which it is bushed into various processes as per its usage i.e. depending upon the domestic and industrial usage of water. In the very first step, solids and objects that do float are removed from the water that has to be treated. When this effluent water gets shuffled from the sewers it crosses the bar rack, which helps in holding back solid items; and allows the remaining liquid to pass to another container. It is here where inorganic substances as sands or stones are eliminated. Then after, it is being handled by sedimentation process; and in this solids are being arranged for land filling. Consequently, it is disinfected so that pathogenic bacteria are killed and extra chlorine is cleared. Finally, the treated water is drained out in natural water resources, and the remains in the container can be used as fertilizers.



Secondary Therapy
The initial stage of treating effluents is a conventional way of handling wastewater; and as per The Environmental Protection Agency, this much of treatment is not enough. As the bacteria and other elements present can still leave behind harmful effects on the environment, hence it needs to undergo next level of treatment, which can be biological. Whereas, the primary level of treatment can take out 50% of the dirt present in water, on the other hand, when given secondary treatment 85% of pollution can be eliminated.

Advanced Treatment
While domestic sewage needs little of efforts for purification, but when it comes to purifying industrial waste, one needs to give advanced processes; then only heavy metals besides toxic metals can be eliminated. Such procedures can be taken place through micro filtration, carbon absorption and a number of numerous procedures of evaporation. Chemical precipitation too helps in attaining this.

All of us are well aware that if sewage will be disposed of without any sort of treatment, will give a very adverse effect on the nature. Due to negligence in previous time, situation is already grim. As water gets discharged in environment, polluted water needs to be treated at regular intervals.
