EFFLUENT TREATMENT PLANT


<< Back
 

An Effluent treatment plant is a collection of chemical and physical processes that removes solid and dissolved organic and inorganic materials from a stream of water to make it of equivalent water quality as unused or natural water. This process includes such testing and quality assurance as to confirm that the water quality is maintained at the discharge point. This is performed by a combination of physical, biological, and chemical treatment stages. The most important aerobic treatment system is the activated sludge process, based on the maintenance and recirculation of a biomass composed by micro-organisms able to absorb and adsorb the organic matter carried in the wastewater. Anaerobic processes are widely applied in the treatment of industrial wastewaters and biological sludge. Some effluent may be highly treated and reused as reclaimed water. For some waste waters ecological approaches using reed bed systems such as constructed wetlands may be appropriate. Modern systems include tertiary treatment by micro filtration or synthetic membranes. After membrane filtration, the treated wastewater is indistinguishable from waters of natural origin of drinking quality. Nitrates can be removed from wastewater by microbial denitrification, for which a small amount of methanol is typically added to provide the bacteria with a source of carbon. One of the principle objectives of wastewater treatment is to prevent as much of this "oxygen-demanding" organic material as possible from entering the receiving water. This is some basic methods of treatments as given:

 

  • PRELIMINARY OR PRETREATMENT

    It’s a very first stage, the removal of larger materials and grit that if not removed could hinder subsequent treatment processes.

  • PRIMARY TREATMENT

    It is usually comprised of preliminary treatment followed by primary clarifiers or any solid separators which remove approximately 50% suspended solids and 35-40% B.O.D.

  • SECONDARY TREATMENT

    It’s a Biological Treatment Stage. 90% removal rates of B.O.D. and suspended solids are typical of secondary treatment.

  • TERTIARY TREATMENT

    It’s a final stage, advance technologies generally used for further removal of nutrient, elements & polishing of wastewater.

The industrial effluent treatment plants involve different stages of treatment including physio- chemical treatment and biological treatment followed by tertiary treatment. Integrated functions with simple control make the operation much easier a compact design and can be easily installed on the site. Our engineers can also custom design effluent treatment plants based on the specific application requirement of the customers. We offer a wide range of industrial effluent treatment plants for application in paint shop, diaries, paper mills, oil refineries, leather industry, glass factories, chemical and processing industries etc. These industrial effluent treatment plants are designed to provide a pollution free working environment and recycle the water for other applications. All the effluent treatment plants strictly comply with the design specifications laid down by the regulatory authority.
