Internal Filters of the Water Purifier
Water Purifier

Some doubt the adverse impacts of drinking non-purified water and raise the question, why years of drinking water straight out of the tap has never caused them any problem?

First, population growth and increasing physical, chemical, industrial contamination of water and soil necessitate the use of water purifiers. Second, it must be noted that some diseases do not strike with immediate, visible symptoms, and that does not mean they do not exist. There are diseases caused by protozoa, viruses, bacteria, parasites, and—most importantly—nitrate from wastewater, such as hepatitis and polio, that call for water treatment as a necessity for human life. The water purifier is not considered a luxury anymore but a requirement that plays a vital role in improving the quality of drinking water and household sanitation.

The function of Home Water Purifier Filters

  • Polypropylene Filter: Used to remove all precipitates, sand, dirt, pipe rust, sludge, and solids of down to five microns, with a similar function to the sand filter as it absorbs visible physical pollutants.

  • Activated Carbon Filter: Employed to remove chlorine, pesticides, trihalomethanes, most organic chemicals in insecticide and pesticides, and colour and odour from water.

  • Carbon Block Filter: For the highest efficiency in removing chlorine and other toxins. 

  • Membrane: Eliminating 98% of harmful minerals, including microbiological pollutants, nitrate, nitrite, and heavy metals.

  • Linear Carbon Filter: Improving the taste and odour of water when it is stored in the tank for a long time.

  • Bio-ceramic filter: To adjust the water pH and its taste.

  • UV lamp: UV radiation using a UV lamp to disinfect and sterilize the water of its micro-organisms.

  • Alkaline Filter: For raising the water pH.

  • Minerals Filter: Adding the minerals needed by the body after treatment to improve its taste.

    Water Purifier

Water treatment using the six-stage home water purifier:

  • First Stage: At this stage, dirt, sand, and other suspended solids are removed from water by a 5-micron fibre filter.

  • Second Stage: At this stage, the activated carbon filter placed in the water purifier is responsible for removing gases and chemicals in insecticides and pesticides.

  • Third Stage: The one-micron activated carbon filter removes what managed to pass through the previous two filters by removing chlorine and other materials larger than 1 micron.

  • Fourth Stage: The RO membrane filter, which is basically the main filter of the water purifier is composed of multiple layers of semi-permeable membranes in a central tube and filters out 80–98% of all soluble minerals—including nitrate, lead, and calcium.
    The filter can remove harmful minerals of down to a thousandth of a micron (soluble organic and non-organic substances and microbiological pollutants), as well as softening the water.

  • Fifth Stage: At this stage, the odour and taste of stagnant water in the tank goes away.

  • Sixth Stage: At this point, the UV filter sterilizes the water by UV radiation.
