Water Treatment


Water treatment is any process that makes water more acceptable for a specific end-use, which may be drinking, industry, irrigation, river flow maintenance, water recreation or many other uses. Water treatment should remove existing water contaminants or so reduce their concentration that their water becomes fit for its desired end-use, which may be safely returning used water to the environment. Water Treatment involves the removal of contaminants from raw water to produce water that is pure enough for human consumption without any short term or long term risk of any adverse health effect. Substances that are removed during the process of water treatment include suspended solids, bacteria, algae, viruses, fungi, and minerals such as iron and manganese. Techniques of pollutant removal are aeration, sedimentation, filtration, chlorination..ect.


  • Applications: Hotels, Restaurants, Hospitals, Factories, Schools, Housing Schemes, etc.
  • Techniques Used: Aeration Towers , Activated Carbon filters , Cartridge Filters , Iron Removal Filters.

Waste Water Treatment


Wastewater treatment is a process to convert wastewater - which is water no longer needed or suitable for its most recent use - into an effluent that can be either returned to the water cycle with minimal environmental issues or reused. Waste water treatment can involve physical, chemical or biological processes or combinations of these processes depending on the required outflow standards.


  • Applications: Textile Dying , Vehicle Service Stations, Food Processing Factories, Restaurants…..etc.

Sewage Treatment


Proper treatment of sewage is crucial for places where human wastes are heavily collected. Sewage is a major carrier of disease (from human wastes) and toxins (from industrial wastes). The safe treatment of sewage is thus crucial to the health of any community. Sewage treatment is the process of removing contaminants from wastewater, primarily from human Waste. It includes physical, chemical, and biological processes to remove these contaminants and produce environmentally safe treated wastewater (or treated effluent).


  • Applications: Hotels , Hospitals , Factories, Apartments , Schools, etc.

RO (Reverse osmosis ) Filtration


Reverse Osmosis, commonly referred to as RO, is a process where you demineralize or deionize water by pushing it under pressure through a semi-permeable Reverse Osmosis Membrane. Reverse osmosis can remove many types of dissolved and suspended species from water, including bacteria, and is used in both industrial processes and the production of drinking water. The predominant removal mechanism in membrane filtration is straining, or size exclusion, so the process can theoretically achieve perfect efficiency regardless of parameters such as the solution's pressure and concentration.


  • Applications: Applications: Hotels, Restaurants, Hospitals, Factories, Schools, Housing Schemes, etc.
  • Techniques Used: A Aeration Towers , Activated Carbon filters , Cartridge Filters , Iron Removal Filters.
