About Filtration
The price of water purification equipment in Pakistan, water filtration is a physical process that occurs when liquids, gases, dissolved or suspended substances adhere to the surface or pores of an absorbent medium.
The degree of filtration depends on the number of contaminants, the size of the contaminant particles and the charge of the contaminant particles. Pretreatment prior to filtration, such as the addition of flocculants or powdered activated carbon, or adjustment of pH or chlorine concentration, may be required to protect the membrane surface.
See Water Purifiers and Water Purification Systems for more information.
Microfiltration filters have a pore size of approximately 0.1 microns (pore size varies from 0.05 microns to 5 microns, depending on the filter).
Microfiltration is very effective for removing protozoa (e.g. Cryptosporidium, Giardia).
Micro filtration is usually effective for the removal of bacteria (e.g., Campylobacter, Salmonella, Shigella, E. coli).
Microfiltration is ineffective at removing viruses (e.g., enteric bacteria, hepatitis A, norovirus, rotavirus).
Microfiltration is ineffective in the removal of chemicals.
The pore size of ultrafiltration filters is approximately 0.01 microns (pore sizes range from 0.001 microns to 0.05 microns, depending on the filter, with molecular weight cutoffs (MWCO) of 13,000 to 200,000 Daltons). Ultra filtration filters remove particles based on size, mass and charge.
The Ultrafiltration is very effective at removing protozoa (e.g., Cryptosporidium, Giardia).
Best Ultra-filtration is very effective at removing bacteria (Campylobacter, Salmonella, Shigella, E. coli, etc.).
Ultrafiltration is usually effective in removing viruses (e.g., enteric bacteria, hepatitis A, norovirus, rotavirus).
Ultrafiltration is not very effective at removing chemicals
Nano filters have pore sizes of approximately 0.001 microns (pore sizes range from 0.008 microns to 0.01 microns, depending on the filter, and molecular weight cutoffs (MWCO) from 200 to 2000 Daltons), and nano filters are based on the size, mass, and charge of the particles to be removed.
Nano filtration is very effective in removing protozoa (e.g., Cryptosporidium, Giardia).
The Nano-filtration is effective for the removal of bacteria (e.g., Campylobacter, Salmonella, Shigella, E. coli).
The Best Nano_filtration is very effective in removing viruses (enterovirus, hepatitis A, norovirus, rotavirus, etc.).
Nanofiltration is often very effective in removing chemicals.
The Best RO Plants
Reverse osmosis is the process of passing water from a dense aqueous solution through a semi-permeable membrane, as opposed to natural osmosis. Reverse osmosis membranes usually have a prefilter and a postfilter.
The pore size of a reverse osmosis filter is approximately 0,0001 microns.
Reverse osmosis systems are very effective at removing protozoa (e.g., Cryptosporidium, Giardia).
Bacteria (e.g., Campylobacter, Salmonella, Shigella, E. coli).
Effective in removing viruses (enterovirus, hepatitis A, norovirus, rotavirus, etc.)
Reverse osmosis system removes common chemical contaminants (metal ions, water salts) such as sodium, chloride, copper, chromium and lead, and reduces arsenic, fluoride, radium, sulfate, calcium, magnesium, potassium, nitrate and phosphorus.
Distillation unit
A distillation unit is a process that heats water to its boiling point and obtains condensed water vapor, leaving behind many impurities.
Distillation units are very effective in removing protozoa (e.g. Cryptosporidium, Giardia).
The distillation unit is very effective in removing bacteria (Campylobacter, Salmonella, Dysentery, E. coli, etc.).
It is effective in removing viruses (enterovirus, hepatitis A, norovirus, rotavirus, etc.).
The distillation system removes common chemical contaminants including arsenic, barium, cadmium, chromium, lead, nitrates, sodium, sulfates and many organic chemicals.
The UV treatment systems with pre-filtration
Best UV pre-filtration treatment is a treatment method that uses UV light to disinfect water and reduce the number of bacteria present.
U-V treatment systems are very effective in eliminating protozoa (Cryptosporidium, Giardia, etc.).
UV treatment systems are very effective in eliminating bacteria (Campylobacter, Salmonella, Shigella, E. coli, etc.).
Only U-V curing systems are very effective in eliminating viruses (enterovirus, hepatitis A, norovirus, rotavirus, etc.).
UV curing systems are not effective in removing chemicals.
Water softeners
Water softeners use ion exchange technology to reduce water hardness (calcium and magnesium) chemically or ionically. They can also remove iron, manganese, heavy metals, some radioactive substances, nitrates, arsenic, chromium, selenium and sulfates. They do not protect against protozoa, bacteria or viruses.
Please remember
Point-of-use (POU) water purification systems typically treat water in batches and deliver it to taps, such as kitchen sink and auxiliary faucets.
Point-of-entry (POU) water treatment systems typically treat most of the water entering the home. Point-of-entry systems (whole-house systems) are typically installed behind the water meter.
The above treatment technologies can be used in combination to further reduce pathogens. Flocculants, carbon, aluminum and iron salts can be added to the filtration system to remove chemicals from the water.
Hygiene
In addition to providing safe drinking water for your family, good personal hygiene helps protect you and others from waterborne diseases.
Wash your hands before preparing and eating food, after using the restroom, after changing diapers, and before and after caring for patients.
Water is a basic human need, but in Pakistan it is not safe to drink it without a household water purifier. Contaminated water can lead to diarrhoeal diseases like cholera, so having a household water purifier is not only essential but also life-saving.
So, choosing the right home water purifier is not easy as there are many water purifiers and whole house filtration systems available, but it is a very worthwhile choice. Since science has shown that there is no longer any guarantee that bottled water is safe to drink, improving the quality of drinking water by installing a home water purifier is a logical and sensible choice. Aqua Cleanse offers the best water purifiers at reasonable prices in Lahore, Islamabad and Karachi.
RO Systems Ideal for Home Use
Reverse osmosis is a method of water filtration that utilizes a process similar to osmosis. Osmosis is the selective movement of water through a membrane from a place of low solvent concentration to a place of high solvent concentration. This is a similar process to filtering out contaminants and metals in water.
The process of reverse osmosis systems allows for the removal of large particles, impurities, and unwanted molecules from a particular solution.
In this process, the solution is passed through a semi-permeable membrane to remove ions and unwanted particles from the drinking water.
Water Logic provides the best RO units at affordable prices in Pakistan and also specializes in reliable and cost-effective home RO units, commercial RO units and industrial reverse osmosis (RO) water treatment and purification systems.
