The four main types of chemicals used in wastewater treatment are pH neutralisers, anti-foaming agents, coagulants and flocculants. The most straightforward class of chemicals is pH neutralisers, although why and how they are used varies depending on the process producing the wastewater.
The ETP plants use evaporation and drying methods, and other auxiliary techniques such as centrifuging, filtration, incineration for chemical processing and effluent treatment. ADVERTISEMENTS: The treatment of effluents is essential to prevent pollution of the receiving water.
Focus on removing TSS from wastewater first.
Reducing TSS will almost always reduce BOD too. First and foremost, use mechanical screens such as roto-strainers or bar screens to get large solids out. This will also protect your downstream Dissolved Air Flotation (DAF) equipment from damage or clogging.

There are four ways in which a water treatment plant can operate: Effluent Treatment, Sewage Treatment, Common and Combined Effluent Treatments and Activated Sludge Treatment
Alum is the coagulant of choice for many industrial and sanitary wastewater treatment applications, due to its high efficiency, effectiveness in clarification, and utility as a sludge dewatering agent. The chemical leaves no residual color, offers very good turbity removal, and is available as G.R.A.S
COD or Chemical Oxygen Demand is the total measurement of all chemicals in the water that can be oxidized. TOC or Total Organic Carbon is the measurement of organic carbons. BOD- Biochemical Oxygen Demand is supposed to measure the amount of food (or organic carbons) that bacteria can oxidize.
There are three main stages of the wastewater treatment process, aptly known as primary, secondary and tertiary water treatment. In some applications, more advanced treatment is required, known as quaternary water treatment
EFFLUENT. SLUDGE. • ETP (Effluent Treatment Plant) is a process design for treating the. industrial waste water for its reuse or safe disposal to the environment
ETP plays an important role in treating industrial wastewater as well as sewages generated from households. ... Also, expulsion of some toxins is necessary prior to release the wastewater in ETPs. • Results in clean reusable water — ETPs manufactured by any leading packaged ETP manufacturer ensure safe and clean water
Biochemical oxygen demand (BOD) is the amount of oxygen it takes to degrade organic matter. Chemical oxygen demand (COD) is the amount of oxygen required to oxidize organic compounds (>500 milligrams per liter). Total suspended solids (TSS) is the total amount of suspended materials (>250 milligrams per liter).
