Effluent treatment plant cleans industrial effluents, contaminated water from outlet pipes, reservoir, rivers, lakes etc and reclaim the water resource for using in different purposes. ETP are mostly installed in industries like textile industry, Medicine manufacturing, leather industry, and chemicals industry.
Correspondingly, What is STP capacity? Sewage Treatment Plant (STP), Capacity: 5 KLD to 50 MLD, Waste Water Treatment Plant.
What is the sequence of treatment process in ETP? What is the sequence of treatment process in ETP? There are majorly three stages of wastewater treatment i.e., Primary, Secondary and Tertiary treatment. There are also substages in these processes such as bar screening, Aeration, Clarification, Chlorination, Water analysis, water testing and water disposal.
Furthermore, What is done in sewage treatment plant?
Sewage treatment (or domestic wastewater treatment, municipal wastewater treatment) is a type of wastewater treatment which aims to remove contaminants from sewage to produce an effluent that is suitable for discharge to the surrounding environment or an intended reuse application, thereby preventing water pollution …
What is textile effluent treatment?
Textile wastewater can be treated using biological treatment processes, chemical precipitation, adsorption, and membrane technology. Generally, biological treatments are preferred to remove persistent color from wastewater due to their low cost (Lin et al., 2012; Mutamim et al., 2012).
What is the term GREY water? Greywater can be defined as any domestic wastewater produced, excluding sewage. The main difference between greywater and sewage (or blackwater) is the organic loading.
What is Equalisation tank in STP? The equalization tank is the first collection tank in an STP. Its main function is to act as buffer: To collect the incoming raw sewage that comes at widely fluctuating rates, and pass it on to the rest of the STP at a steady (average) flow rate. During the peak hours, sewage comes at a high rate.

- Electro Coagulation System.
- Sequential Bio Reactor (SBR)
- Rotating Bio Reactor (RBC)

What are the two products of sewage treatment?
Wastewater treatment is usually broken down into two sections: primary treatment, which removes grease, dirt, gravel, and floatable waste, and secondary treatment, which removes even more suspended solids and pollutants by using biological processes.
What is textile wastewater? Textile wastewater (TWW) is one of the most important hazardous wastewaters for ecosystems when it is discharged directly into water streams without proper treatment. From: Sustainable Fibres and Textiles, 2017.
What are the main sources of pollutants in textile effluent? The presence of different dyes like Sulphur, Azoic, indigoids, nitrates, acidic acid, soap, enzymes, complex compounds, heavy metals and certain auxiliary chemicals all are make the textile effluent highly toxic.
What types of pollutants are there in textile effluent?
Textile effluent is heavily contaminated with pollutants such as dyes, dissolved solids, suspended solids and toxic metals. The main factor to be considered in textile effluent is total dissolved solids (TDS). Because of the use of common salt and Glauber salt, the level of TDS increases in textile wastewater.
What is green water? Green water is the water held in soil and available to plants. It is the largest freshwater resource but can only be used in situ, by plants. Green water is managed by farmers, foresters, and pasture or rangeland users.
What is the term black water?
Definitions. blackwater is any waste from toilets or urinals. greywater is wastewater that has been used for washing, laundering, bathing or showering. wastewater includes both blackwater and greywater.
What is blackwater used for? Increasingly they are championing water reuse, using maturing technology to recycle blackwater—raw sewage—to graywater, water that is treated to standards clean enough to be used in buildings’ cooling towers, toilet flushing or irrigation.
