BASIC ETP INTERVIEW QUESTIONS AND ANSWERS

BASIC ETP INTERVIEW QUESTIONS AND ANSWERS:

 

Question Number 1: What is E.T.P?

Answer: The Effluent treatment plants (ETP) are used for the removal of high amounts of organic compounds, debris, dirt, grit, pollution, toxic, non-toxic materials, polymers etc. from industrial effluent. The ETP plants use evaporation and drying methods, and other auxiliary techniques such as centrifuging, filtration, incineration for chemical processing and effluent treatment.

Question Number 2: What is Screen chamber?

Answer: This chamber removes relatively large solids to avoid abrasion of mechanical equipment and clogging of hydraulic system. It works like a filter. By filtering waste water, it removes threads, pieces of fabrics, small metal pieces etc. In this unit a rotating brush is used for clean the pores if screen. The brush rotates periodically. 
Question Number 3: What is Collection tank?

Answer: The collection tank collects the effluent water from the screening chamber, stores and then pumps it to the equalization tank.

Question Number 4: What is Equalization tank?

Answer:

• The effluents do not have similar concentrations at all the time; the pH will vary time to time.
• Effluents are stored for up to 8 to 12 hours in an equalization tank resulting in the homogeneous mixing of effluents and helping in neutralization.
•  Continuous mixing also eliminates settling of solids within the equalization tank.
•  It Reduces SS, TSS.
