Water Purification

Pre-Filtration
The purification process starts with a pre-filter, screening the source water at the point of entry. In the Noah product line, the pre-filter screens are incorporated with the inlet hose. This is essential in preventing the system from becoming plugged with rocks, mud, feces and other large debris.

Microfiltration

Microfiltration is used to treat drinking water: it improves the quality and shelf life of the water. Microfiltration is a filtration process which removes contaminants from the water by passage through a microporous membrane. A typical microfiltration membrane pore size range is 0.1 to 10 micrometres (┬Ám). Increasingly used in drinking water treatment, it effectively removes major pathogens and contaminants such as Giardia lamblia cysts, Cryptosporidium oocysts, and large bacteria.

  • Sand filter with 2 layers media.
  • Filtration up to 5 microns.
  • Active carbon filter to remove biocides.
  • Backwash system with periodical wash system.
  • Micro filtration up to 1 micron.
  • Water quality detection at inlet and outlet.
Ultrafiltration

Ultrafiltration is a process similar to microfiltration. The main difference is the "tighter" retention behavior. Ultrafiltration membranes keep much smaller particles from passing through the membrane than microfiltration membranes do. Typically the particle size is measured by molecular weight; ultrafiltration membranes have retention characteristics from 1,000 to 1,000,000 molecular weight.

Reverse osmosis (RO)

Reverse osmosis is most commonly known for its use in drinking water purification from seawater, removing the salt and other substances from the water molecules. Reverse osmosis is a filtration method that removes many types of large molecules and ions from water by applying pressure to the water when it is on one side of a selective membrane.

  • High pressure pump up to 50 bar
  • 8" membranes
  • Filtration of water with maximum of 45,000 tds

 

Disinfection
Disinfection is one of the most important steps in the purification of water from cities and communities. It serves the purpose of killing the present undesired microrganisms in the water; therefore disinfectants are often referred to as biocides.

  • Chlorine dosing unit to improve quality and shelf life of the water Used in drinking water treatment, it effectively removes major pathogens and contaminants such as Giardia lamblia cysts, Cryptosporidium oocysts, and large bacteria.

Ultraviolet treatment
Ultraviolet treatment is the final, and in most cases, the most important step in the purification process. The water is exposed to intense dosages of UV light. This exposure effectively destroys viruses, bacteria, fungi, algae and protozoa.

  • UV-treatment with 80W lamp to kill bacteria
