Residential water purifier
This article is made as a guide to home water purification, not as a recommendation. Before installing a home water purification system, contact Giti Aviyeh purification group for advice.
Filtration is a physical process that occurs when liquids, gases, soluble or suspended solids adhere to the surface or pores of an adsorbent medium.
Pollutant filtration depends on the amount of pollutants, the size of the pollutant particles and the amount of pollutant particles. Depending on the domestic water requirement, pre-treatment pre-treatment may include the addition of coagulants and activated carbon powder, adjustments in pH or chlorine concentration, and other pre-treatment processes to protect the filter membrane surface.
Reverse osmosis system
The reverse osmosis system uses a process that reverses the flow of water in a natural osmosis process so that water is transferred from a thicker solution to a thinner solution through a semi-permeable membrane. Before and after filters are often included with the reverse osmosis membrane itself.
A reverse osmosis filter has a pore size of approximately 0.0001 microns.
Reverse osmosis systems are very effective in killing protozoa (eg Cryptosporidium, Giardia).
The reverse osmosis system is very effective in killing bacteria (eg, Campylobacter, Salmonella, Shigella, E. coli).
Reverse osmosis systems are very effective in killing viruses (eg, enteric, hepatitis A, norovirus, rotavirus).
The reverse osmosis system removes common chemical contaminants (metal ions, aqueous salts) including sodium, chloride, copper, chromium and lead. May reduce arsenic, fluoride, radium, sulfate, calcium, magnesium, potassium, nitrate and phosphorus.
Distillation systems use a process to heat water to boiling point, then collect water vapor as it condenses, leaving behind many contaminants.
Distillation systems have a very high effect on the destruction of protozoa (eg Cryptosporidium, Giardia).
Distillation systems are very effective in killing bacteria (eg, Campylobacter, Salmonella, Shigella, E. coli).
Distillation systems are very effective in killing viruses (eg, enteric, hepatitis A, neurovirus, rotavirus).
Distillation systems reduce common chemical contaminants including arsenic, barium, cadmium, chromium, lead, nitrate, sodium, sulfate and many organic chemicals.
Ultraviolet filtration systems (with pre-filtration)
Ultraviolet treatment with pre-filtration is a process that uses ultraviolet light to disinfect water or reduce the amount of bacteria present.
Ultraviolet filtration systems are very effective in killing protozoa (eg Cryptosporidium, Giardia).
Ultraviolet filtration systems are very effective in killing bacteria (eg Campylobacter, Salmonella, Shigella, E. coli).
Ultraviolet filtration systems are highly effective in killing viruses (eg, enteric, hepatitis A, norovirus, rotavirus).
Ultraviolet filtration systems are not effective in eliminating chemicals.
Water softeners use ion exchange technology to remove chemicals or ions to reduce the amount of hardness (calcium, magnesium) in water. They can also be designed to remove iron and manganese, heavy metals, some radioactivity, nitrate, arsenic, chromium, selenium and sulfate. They do not protect against protozoa, bacteria and viruses.
Please note that:
Point-of-use (POU) water treatment systems typically treat water in batches and deliver water to a faucet such as a kitchen sink faucet or auxiliary faucet.
Inlet water treatment systems (POEs) typically treat most incoming water to a residence. Inlet systems or whole house systems are usually installed after the water meter.
The therapeutic technologies described can be used in conjunction with each other to further reduce pathogens. Adding coagulant salts, carbon, alum and iron to filtration systems may help remove chemicals from the water.
In addition to providing healthy drinking water to your family, you can protect yourself and others from waterborne illness by taking care of your own health.
