What is the Importance and How Does an Effluent Treatment Plant Work

Applying environmental awareness in the treatment of liquid waste

The effluent treatment plant design, is the main investment for anyone who wants to start treating the liquid waste produced by your company. The installation of an effluent treatment plant is necessary since, if liquid waste is not properly treated before being returned to the environment, it can cause irreversible damage to nature.

Inadequate disposal of effluents is responsible for polluting and contaminating not only soil or water, but also the ecosystems present in those sites that directly impact human health. In addition, effluent treatment laws at the international, federal, state and municipal levels are increasingly stringent, as well as the environmental awareness of customers, who are now giving preference to companies that are concerned with sustainability and have their own system Of effluent treatment plan.

What are Industrial Effluents?

Industrial effluent is the dumping of liquid waste pollutants from manufacturing processes that range from waste from the industrial processes themselves, to domestic sewage. That is, it is all water that is used in an industry and that then needs to be discarded and treated by an effluent treatment plan.

The industries that produce effluents and, consequently, must implement etp plant design, are the automotive industry, breweries, distilleries, dyeing, cosmetics, mining, pharmaceutical, food, animal feed, hygiene and cleaning industries.

An industry can use water for a variety of purposes, such as for washing the factory floor or some equipment in the production process, for incorporation into the product itself and for cooling systems and steam generators. In all of these uses, the industry is producing liquid waste that needs to be treated by an effluent treatment plant before being thrown into the wild.

This wide variety of industries and industrial activities can generate liquid waste with different characteristics, and in order to carry out the treatment and implement the appropriate effluent plant design, the company needs to know the effluent it is producing. For this, it is necessary to know certain particularities of the tailing, such as the volume produced and the specific composition, which involves toxicity, quantity of pollutant loads and organic load, presence of contaminants, concentration of components, among other aspects.

Implementation and operation of an effluent treatment plant

There are numerous processes involved in effluent treatment plant, such as physical, chemical, biological, batch and flow processes. There are also several types of reactors, such as fixed bed reactors, fluidized or expanded bed and sludge blanket. In order to determine which type of process and reactor is most suitable for each industry, it is necessary to know the characteristics of the effluent produced and to adapt to the needs of the company in question.

The biological treatment consists of removing the organic matter present in the liquid waste by two modes: anaerobic or aerobic processes. The aerobic process is characterized by the use of activated sludge, aerated lagoons, among other techniques, while the anaerobic process is marked by the use of biofilms, biocontactors and some lagoons. Physical treatment is responsible for removing suspended solids through separations such as filtration, flotation, and sedimentation. Finally, the chemical treatment promotes the removal of pollutants through the addition of chemical reagents and the consequent chemical reaction promoted by them, such as coagulation processes, oxidation, pH neutralization and chlorination for disinfection.

Effluent Treatment Plant to preserve our environment

Water is polluted because of industrial waste. Industries emit a lot of waste substances which when disposed get contaminated with water and become a serious threat for the environment. Water is among the most important resources for our living and we cannot afford to pollute the water. Polluting the water causes serious damage to the water habitat and the overall ecosystem. Water should not be wasted and it should be treated with effluent treatment plant and it should be preserved, and saved to be used later. It’s quite challenging to save our water being polluted from industrial resources for a healthy habitat and for our own use.

Industrial pollution has been a big menace lately. With the country developing at a rapid pace, industries are sprouting in every suburb as well as urban regions. Whatever industry it may be, they pollute the environment with synthetic and chemical substances that are harmful to the environment. The challenge is to keep the industrial waste separate from the water flow. Environmental engineers also play a big role in preserving the environment. They are involved in effluent treatment plant projects and advise industries on way how not to pollute the environment and preserve it. Industries pollute natural resources like air, water and land to a great extent that it becomes unusable. These are the very essential fabric of our living and we definitely cannot afford it.

As the waste water exits the industrial area, it flows through the agricultural land and later into the natural water resources. While it flows through the agricultural lands, the soil gets polluted and barren. The once yielding land becomes barren and doesn’t yield crops anymore. It would be a big blow for the farmers and economy if proper care is not taken to dispose the industrial waste from the industries.

The ultimate solution for this situation is to treat the water and convert it into pure water before it is disposed into the natural water resources. During the preliminary treatment of water, the solid substances like oil, greases that float over the water are first removed. This step is quite common across industries, households and civil terminals. During this step certain insects and biological activities are also removed from the water.

During the secondary step the water is allowed to pass through aerators where oxygen is passed into the water. The reason for passing oxygen is that the chemical structure of the water will be preserved. Also, a certain amount of chlorine is added to the water. This process is called as chlorination. The amount of chlorine that is added depends on the pH value of the water. Further, the water is separated from hard water and soft water. The hard water is passed on to re-circulate to further remove impurities and the soft water is carried over to the next step of purification.The semi-purified water is allowed to pass through a tertiary treatment. During this phase thick materials like paints, oils, greases and other chemical substances are separated from the water. In this phase organic matter is passed to purify the water.

Effective steps need to be taken in-order purify water through effluent treatment plant manufacturers before it is allowed to pass on into the natural water resources. It helps to save and preserve our environment.
