What is effluent treatment plant PDF?

• ETP (Effluent Treatment Plant) is a process design for treating the. industrial waste water for its reuse or safe disposal to the environment. • Influent: Untreated industrial waste water.

How do you calculate the capacity of the effluent treatment plant?

Multiply your Minimum Population (P) by 150 to get your daily estimated wastewater production. For example, a three bed house with a Minimum Population (P) of 5 people would have a daily estimated wastewater production of 750 litres per day (5 x 150).

What is the process of ETP?

The principle of operation of ETP is Physico-Chemical treatment followed by Polishing Treatments like –Sand Filtration, Activated Charcoal treatment (Adsorption), Ozonisation (Chemical Oxidation), Ultra Filtration (UF), Reverse Osmosis (RO) and evaporation (If required).

What are the 3 grades of waste water?

There are three main stages of the wastewater treatment process, aptly known as primary, secondary and tertiary water treatment.

What is ETP capacity?

ETP (Effluent Treatment Plant), Capacity: 100 L To 50 KL.

What are the chemicals used in ETP?

Offering you a complete choice of products which include Poly Aluminium Chloride Liquid, Anionic Polyelectrolyte, Cationic Polyelectrolyte Powder, Poly Aluminium Chloride Powder, Caustic Soda Lye and Caustic Soda Flakes.

What are the textile effluent treatment processes?

The textile effluent treatment processes may be certified out in several stages. Preliminary treatment processes of dye waste include equalization, neutralization and possibly disinfection. Primary stages are mainly physical and include screening, sedimentation, floatation, and flocculation.

What methods of effluent treatment are followed in ETP plant?

Coagulation, Flocculation and Precipitation Methods Followed in ETP Plant: This should be considered as the first stages of the effluent treatment plant. The coagulation is a process, which involves precipitation of impurities to produce microflocs. This can be achieved by pH adjustment or by addition of inorganic or organic coagulating chemicals.

How to deal with mutagenic dye effluents in textile?

Some also have mutagenic effects, especially azo dyes. There are various methods used for the treatment of textile dye effluents such as chemical methods, physical methods, biological methods by using enzymes, microorganisms [10] (Fig. 1). Traditional remediation methods of cleanup are ineffective in dealing with this toxicity.

Why should wastewater from textile industries be treated before discharge?

This excessive dye laden wastewater has great impacts on photosynthetic activity in aquatic plants and animals, for example, fish. It may also affect human health due to the presence of components like heavy metals and chlorine in manmade dyes. Thus, wastewater effluent from textile industries must be treated before discharge into the water body.
