The water quality of domestic water in most cities in China is poor, and the pollution is gradually increasing. Therefore, domestic water treatment equipment has become an important product of household water filtration. With the gradual improvement of living conditions, water softeners and water purifiers have become the objects of many people's household decoration.

Part1: Introduction of Domestic Water Treatment Equipment for Pollution Filter

At present, water treatment equipment on the market generally includes water softener, water purifier, water purifier, precision filters and other types, while water treatment products commonly used in families are water purifier and water softener.

I. Water purifier

Water purifier is also known as water purifier, the biggest use is to purify tap water, water treatment equipment manufacturers through the adsorption of activated carbon, KDF, filter out suspended substances in tap water, bacteria, rust, algae, microorganisms and other impurities, so that daily drinking water can become pure; The residual chlorine in the incoming water is healthier to drink after filtration.

Working Principle: The working principle of water purifier is to purify water layer by layer through various filter elements (such as PP cotton, activated carbon, reverse osmosis membrane, etc.) to achieve the purpose of removing impurities. Tap water can remove sediment, rust, colloid, bacteria, suspended matter and other substances through PP cotton filter, granular activated carbon filter, PP cotton filter, reverse osmosis filter and Post-Activated carbon filter.

2. Water softener

Water softener mainly removes calcium and magnesium ions from water by ion exchange resin to reduce water hardness. Compared with tap water, soft water has obvious taste and feel. It has high oxygen content and low hardness. It can effectively prevent stone disease, reduce the burden of heart and kidney, and is beneficial to health.

Working Principle: Household softening water equipment uses ion exchange technology to exchange functional ions on resin with calcium and magnesium ions in water, so as to adsorb excess calcium and magnesium ions in water and achieve the purpose of removing scales (calcium carbonate or magnesium carbonate).

Pure Water Machine

Pure water machine is a kind of water purification equipment which uses multi-stage filter element to purify water quality. It uses physical methods such as filtration, adsorption and reverse osmosis without adding chemical substances.

Working Principle: Applying certain pressure on water to make water molecules and ionic mineral elements pass through reverse osmosis membranes, while most inorganic salts, organic substances, bacteria and viruses dissolved in water can not pass through reverse osmosis membranes, so that permeated pure water and concentrated water can not be penetrated are strictly separated.
