Why Industries Using Sewage Treatment Plants for Removing Pollutants ? | Chokhavatia Associates

In order to free the water consumed for irrigation or drinking and even household purposes from all sorts of harmful contaminants, Sewage Treatment Plant plays a quite crucial phenomenon. The containments present in the waste water should be significantly decreased by getting rid of bacteria, suspended solids and all other organic wastes as well as chemicals that make the water polluted so that can be reused again.

Sewage Treatments denotes domestic wastewater management and seeks removal of pollutants from household sewage that consists of domestic and runoff. On an average, environmental engineers are accountable for designing and erecting facilities where wastewater is to be treated. There are various ways and means as physical, chemical besides biological approaches through which wastewater can be treated and is sent back to the environment so that it can be reused.

The most accepted Sewage Treatment Plant that is usually set up for treating sewage embraces three stages-i.e. entire procedure has to undergo primary, secondary &tertiary stage of treatment. In the very first step solids are mined out from the waste water and it is through usage of home cultivated water borne micro-organisms dissolved matter is transformed into solid masses. Residues remained are there after nullified and then after thrown away or re-used.  Thus, the water gets disinfected either physically or chemically with the support of lagoons or microfiltration.

In the end, the water that has been treated is now discharged into either river, stream, wetland or either it can be reused for irrigating farms.

The treatment plant developed for cleaning sewage works to eradicate suspended solids in addition to bio chemical oxygen demanding waste also known as BOD as this helps to reduce fish kill, as of diminishing oxygen levels that can leave adverse effects on marine life.  Diverse forms of treatment are as follows.

1. Primary Treatment

In this phase substances that can be removed effortlessly from waste water are eradicated as oil /fat/ racks and even trash..

2. Secondary Treatment 

This procedure cuts down the biological toxins that are present inside the sewage. At this juncture micro-organism are assisted to eliminate the undesirable elements present in the sewage.

3. Tertiary Treatment

This step emphasises on the betterment of the quality of the water, prior to sending back to the environment for usage for all purposes. This can be accomplished either by treating it by artificial filters or by natural filters like marshlands and even lagoons. With the help of treatment excess phosphorus and nitrogen can be removed.

For total removal of microrganism, a treatment plants have to often take a treatment of chlorination prior to release of treated waste water. Ultimately this chlorine is being eliminated from water after being chemically treated by sulphur di oxide reaction; and this helps in making water safe for the life that is dependent on it.

At last, this treated water is released in river, ponds lakes or even sea whatever is the closest destination. There are lots of services providers who provide solutions to fix drainage problems in a very cost effective manner.

The Importance of Environmental Management Plan | Chokhavatia Associates

Environment plays a pivotal role in the life of the people. It basically means the conditions of the surrounding areas and it is only because of good environment, humans have been able to survive for so long. Any company is expected to follow certain norms and regulations in order to be affiliated by the government and not be fined heavily. One of the norms that a company needs to follow is related to the pollution control. Even though, it's opposition comprises of many advocates, it still remains to be one of the strongly implemented rule, and rightfully so.

A company needs to follow certain standards in their factories and in their other work areas, including labs, hospitals etc. This is to make sure that the environment is not affected by the constant work being done in them. Each and every waste material needs to be discarded off, only after all the harmful components have been taken out. If a company does not follow these norms, then there is a good chance that they will have to pay heavily in terms of fine or in some cases; the license might get revoked due to this kind of negligence.

Things to keep in mind while making environmental management plans

The first and foremost thing to keep in mind while making the plan is to know what kind of waste is being produced in the workplace. If it is an office workplace and then the waste generated is harmless and hence easily discarded. But if, it is waste of a hospital or factory that requires elements that make radiations, then the plan of action would be different.

Depending on the waste material a company is bound to produce, action plan comes into play. If it is toxic gases that are to be released in the making of the desired products, then chimneys are installed, if, the waste product is liquid based, treatment plant is made and if it is solid or radiation based, then appropriate measures for the same are taken. This can be done in two ways; either the company hires a company to make these Environmental Treatment Plans or makes a department in their own company, solely for this job. This department or company, depending on the company's choice, makes the entire plan and recommend the steps that need to be taken.

Afterwards, the company either hires a company which can provide the needed services or they install the equipment themselves, and keep it as a part of the whole process.

In the end, it is absolutely a must to have these two processes running simultaneously and never compromise on the quality of the waste disposal due to budget cuts. If a company decides to not follow the said conditions, it is bound to come under fire from the people of the nation and the law. There are strict actions that can be taken by the government and the judiciary system but the main problem still remains the Backlash that comes from the customers.

What is included in an Environmental Management Audit ? | Chokhavatia Associates

Industries are one of the complicated facilities with series of processes to manufacture raw materials or products. Often times, chemicals and other substances are essential to run the manufacturing plant. This can result in pollutants damaging the surrounding environment, also causing harm to public health. This leaves us to the point to understand the necessity of Environmental Audit.

Why Do You Need An Environmental Management System?

Industries in the act of producing products and goods have growing concerns about generation of waste, effluents and hazardous chemicals. Moreover, there is a necessity to strike balance in managing industrial wastage and the environment. In this regard, United Nations have also taken the initiative to propagate cleaner production and environmental ministry overlooks industrial processes for the good of the society. This blog details about how Environmental Management Systems can address these issues to preserve our environment from industrial pollution.

Role of Environmental Management Systems

In order to resolve the industry pain points, the Environmental Management System (EMS) plays a key role to sustain an organization while being non-hazardous. Effective environment management plan always has a desirable outcome. The environmental management consultant help to design and build non-hazardous production facility. For profitability concerns, EMS also focuses on plant implementation that derives operational efficiency.

Environmental Consultants In India | Chokhavatia Associates

The habitat where we reside, things associated with it and the whole enchilada around which we can visualize with our naked eyes, we can experience compromises of the environment we live in. So, environment and its inhabitants are inter-dependent and complimentary to each other; or we can say that this natural surrounding belongs to us and we belong to our surrounding. If we migrate to the place of which the environment is totally opposite, then ours, somehow makes us uncomfortable to us.

Just imagine if we have to stay for few period of time with the Eskimos, how will the situation would be. The environment here will be totally different from that of ours; and while going to bed as well as while waking up will have the vision of ice. It will give a total different feeling, unlike the warmth of our homeland. Hence, as inhabitants of this environment it our foremost responsibility and duty as well to protect our surroundings from all sorts of disasters. At times, we are not sure how to care for our surroundings; and here comes the concept of environmental consultant, who through their expertise work for environment clean up.

Environmental consultants are either individual professionals or a group of experts forming an organization who provide their clients with elucidations, which can help their clients to act as per environmental norms as per decides by legislature. Environmental consultants can either be the one with ample industry exposure before entering this industry, and the other group of professionals are those who are typical environmentalist.Once entrepreneurs are willing to establish an industry or a manufacturing factory whether with a medium or small set up, it is sure that employees working with the organization will shed a certain volume of natural waste on daily basis. The professionals working as environmental consultants provide these entrepreneurs solutions so that hazardous elements from these wastes are been filtered out; and later on are been sent to separate refinery for purification.

With the increasing risk of globing warming and appalling disasters due to four-fold industrialization, environmental protection has been considered as a major apprehension for all the countries across the geographical boundaries. Thus, more and more establishments have turned their faces towards these consultants to adhere with the stern rules and regulations related to environmental clean-up. Environmental Consultants In India are known for their expertise in this field, as they have an ability to deliver an award winning solutions as requirement of their clients.

Environmental consulting is a widely diverse and immensely growing industry; and as per industry reports there is an immense growth in environmental consulting. This growth or rise is due the growing public awareness and concern for the environment. Elected representatives as well as local corporations too are equally concerned with environment thus keep a vigil eye in compliance with environmental regulations.

As humans, it is our fundamental duty to keep our nature pollution free, so that our coming generations live a smooth life; so make sure to contribute in some form or other to make our nature clean and green.

Wastewater Treatment as in Sewage Treatment | Chokhavatia Associates

Wastewater treatment is cover under sewage treatment because in wastewater we purify wastewater as in Sewage contains human and animal waste and pollutants ,effluent. Sometime it contains storm water also.

Wastewater disposed as municipal or commercial wastes and be treated under sewage treatment plants. Wastewater contains both residential and industrial waste to treat. Differentiating solid and liquid waste from the sewage and treat the remaining liquid and make it safe for surroundings and reusable is called “Wastewater treatment” . In wastewater there are three processes called 1) Chemical, 2) Physical and 3) Biological. Considering which type of effluents are in wastewater, process can be apply .

As above wastewater contains Residential waste as well as Industrial waste.

Residential waste is like municipal sewage, remaining waste of house holds, sludge coming from dirty area etc. It contains only grey water .To treat this needs low rate treatment. It tends to be lower in coast and less maintenance. For this We just required physical and biological process. Filtration and clarification which are in physical process of wastewater treatment, can use for this type of wastewater.

Industrial waste contains effluents coming from industry, chemical sludge ,Toxins coming from pharmaceuticals .It contains black water. It is high rate treatment contains high cost and high maintenance. It requires pretreatment which is not full treatment in industry just remove pollutants before it discharge from industry. Pretreatment consist physical process, and for removal of effluents and toxin , Chemical and Biological process apply. For Biological process biological treatment units are use this process is called Activated sludge process.

As above there are three basic processes in wastewater treatment which are describe below:-

 Physical Process:-

Removal of physical substance from the sludge called physical process. It involves filtration, clarification ,sedimentation and aeration. Now Removal of solids settles which are in base is called Sedimentation .Whenever heavy solids go at the bottom, to discard them from wastewater become easy. To increase oxygen in the remaining waste and contaminated water is called Aeration. Passing water through filters and separate solid and liquid part of waste is called Filtration. These all processes are done by physically so its called Physical Process.

It is used in mostly residential area and also in Municipal sewage.

Chemical Process:-

Taking out the existence of contaminants from the wastewater is called Chemical Process. To purify water ,most used treatment is considered to be chlorination. To decompose water and remove bacteria from the waste water, chlorine is most usable chemical. It is a strong oxidizing chemical. By the oxidation we can purify water and make it reusable by controlling the bacteria growth, and for that we can also use agent like ozone.

It is widely use in industrial area and some times it is used in municipal sewage also. In industry PH control and neutralization is also necessary. Carbon is use for this process because of its adsorption property.

Biological Process:-

Making wastewater biochemically decomposed and stabilizing it called Biological Process. This process makes use of bacteria and other microorganisms which are in waste water. It categories in Aerobic and Anaerobic. An aerobic process we have oxygen presence ,and by the bacteria it transform in to CO2.In anaerobic process the sludge is fermented in considered temperature without O2.

What Are The Normal Characteristic Of Effluent Treatment Plant Design | Chokhavatia Associates

The characteristics of the Effluent Treatment Plant Design determine the important factors that are related to it. The biological, chemical, and physical properties that affect the quality of effluent must be considered while designing the treatment plant.

Characteristic of Effluent Treatment Plant

• The physical characteristics of the effluent: You need to consider the physical characteristics of the effluent while designing your plant. This includes the color of the effluent, the constituent solids, its temperature, and even odour. This also means that the presence of suspended solids indicates the poor quality of effluent that makes the treatment difficult.

• Capability to withstand shock loads: While designing the plant, you should also consider the fact that it needs to be able to withstand the shock loads during festival seasons such as Christmas and New Year. The effluent load can also increase during various festivals.
