Effluent Treatment Plant (ETP)

Effluent Treatment Plant (ETP) is generally used in industries to treat the wastewater that is produced. Industrial water is commonly released to water bodies. If they contain harmful chemicals and other elements, they would pollute the water bodies. If the industrial water isn’t stripped off harmful elements before being released into the environment, it can slowly create a scarcity of pure drinking water.

Benefits of ETP:
1. To clean industry effluent and recycle it for further use
2. To reduce the usage of fresh water in industries
3. To preserve natural environment against pollution
4. To meet the standards for emission of pollutants set by the Government & avoid heavy penalty
5. To reduce expenditure on water acquisition

Sewage Treatment Plant (STP)

Apex EE Engineering Limited successfully working with Sewage treatment plant process that includes sewage treatment on primary, Secondary or biological and tertiary treatment process to improve quality of wastewater for recycle. Sewage treatment is the process of removing contaminants from wastewater, primarily from household sewage. It includes physical, chemical, and biological processes to remove these contaminants and produce environmentally safe treated wastewater (or treated effluent).

Technologies Used
• ASP : Activated Sludge Process
• MBBR : Moving Bed Bio reactor
• SAFF : Submerged aerated Fixed Film
• SBR : Sequential Bioreactor
• MBR : Membrane Bio Reactor

Water Treatment Plant (WTP)

We provide a range of mineral water drinking water treatment plants. These plants are one of our most popular utility plants that are known for its high efficiency, leak poof and less maintenance. The most common steps in water treatment used by us include:

Coagulation and Flocculation
Coagulation and flocculation are often the first steps in water treatment. Chemicals with a positive charge are added to the water. 

Sedimentation
During sedimentation, floc settles to the bottom of the water supply, due to its weight. This settling process is called sedimentation.

Filtration
Once the floc has settled to the bottom of the water supply, the clear water on top will pass through filters of varying compositions  and pore sizes, in order to remove dissolved particles, such as dust, parasites, bacteria, viruses, and chemicals.

Disinfection
After the water has been filtered, a disinfectant  may be added in order to kill any remaining parasites, bacteria, and viruses, and to protect the water from germs when it is piped to homes and businesses
