Why we need ETP / STP

As the world has industrialized and its population has grown, the problem of water pollution has intensified. With numerous factories having no choice, inject untreated effluents directly into the ground, contaminating underground aquifers.

Another cause of water contamination is improper strategy of sewage treatment. Since human waste contain bacteria that can cause disease. Once water becomes infected with these bacteria, it becomes a health hazard. There are following sources of sewerage effluent as:

  • Residential apartment
  • Commercial complex
  • Public amenities/convenience
  • Labour camp/Defence/Refugee camp
  • Resorts & clubs
  • Factories/Industries

Waste management is the collection, transport, processing, recycling or disposal, and monitoring of waste materials, without affecting humans and other life systems and without disturbing the environment. The term usually relates to materials produced by human activity either at home / office / industry / agricultural fields / mines etc., and is generally undertaken to reduce their effect on health, the environment or aesthetics. Waste Management is also carried out to recover resources from it.

Sewage / Effluent Treatment Plant is a facility designed to receive the waste from domestic, commercial and industrial sources and to remove materials (containing physical, chemical and biological contaminants) that damage water quality and compromise public health and safety when discharged into water receiving systems.

 

Key Components :

  • Sewage / Effluent collection tank: Where preliminary, effluent is collected.
  • Screening: Any solid materials like; iron particles, stones, plastic items, grass weed, polythene paper, cloth etc are checked through bar screen filter to avoid any damages of the transferring pump.
  • Screening: Any solid materials like; iron particles, stones, plastic items, grass weed, polythene paper, cloth etc are checked through bar screen filter to avoid any damages of the transferring pump.
  • Equalization tank: In which, suspended materials are mixed properly to make a homogeneous mixture. An steering arrangement is employed in the tank.
  • Neutralization tank: Some chemicals are added for maintaining Ph, and for quick flocculation.
  • Sludge tank: After neutralization and flocculation of effluent, the suspended matter undergoes settling which is called sludge. The tank is used for sludge collection.
  • Aeration tank: A mechanical aeration system is adopted in the tank for growth of biomass which are easily coagulates suspended and dissolved particle.
  • Bio reactor: Where biomass is developed in aerobic condition.
  • Lamella filtration: After aeration of effluent, it allows to further settling with certain contact time. Gradually all solids matter deposits at the bottom while the liquid water passed to PSF
  • Pressure sand filter (PSF): Used to remove suspended impurities from the water.
  • Activated carbon filter (ACF): De-odorize any smell in the water.
  • UV/chlorination disinfection: After de-odorizing of water, it is disinfected by either UV (ultraviolet radiation) or with chlorine. So that all types of micro-organisms, pathogens are killed before going to further use.
  • Final water discharge: The discharged water is used for various purpose like, gardening, cleaning, irrigation, car washing
