Pre-filter is the first coarse filtration equipment for the whole house water, which can filter large particles such as sediment, rust, eggs, red worms and other substances in tap water. Pre-filter is usually installed at the front of the pipeline, so it is named with the word "pre"; and "filtration" refers to the basic principle of this kind of equipment.
Pre-filter is usually a "T" structure. Above the "a horizontal" position of the left and right ends of the water inlet and outlet respectively. Below the "vertical" position for the body and the internal cartridge filter, the bottom is the drain, by a valve to control the opening and closing.
The accuracy of the filter ranges from 5-300 microns depending on the brand and model. The main removal pipeline produced by the precipitation of impurities and bacteria, microbial debris, rust, sand and mud particles larger than 5 microns or more impurities, to avoid harm to the human body and skin; and downstream pipelines, water purifiers, water heaters, washing machines, high-grade faucets, showers to play an active role in the protection of the pre-filter can be added to the "hydrochloric acid phosphorus" scale inhibitor cartridge on the water supply, water purifier, washing machine, high-grade faucet, shower. The pre-filter can also add "hydrochloric acid compound phosphorus" scale inhibitor cartridge for solar energy, water boiler to play the role of scale inhibition.
Usually installed after the water meter in the water intake pipe to ensure that the large amount of precipitated impurities generated in the pipe network will not cause harm to the human body, and play a positive role in the protection of concealed pipelines, faucets, appliances and so on. The pre-filter is the nemesis of secondary pollution and is a reliable impurity filtering device .
Filtering sediment, rust and large particles in tap water. It prevents the large amount of precipitated impurities generated in the water supply pipe network of cities and neighborhoods from causing harm to human beings, and plays a positive pre-protection role for concealed pipelines, faucets, plumbing, water heaters, boilers, washing machines, dishwashers, coffee makers, and other water household appliances (water purifiers, water purifiers, and water softeners) and so on.
The pre-filter is the nemesis of secondary pollution of the water supply pipe network, which restores the water quality of the household to the standard of the tap water factory, and is a reliable impurity filtering device, the first water purification gatekeeper of your home.
Remove visible solids impurities in the pipeline, mainly rust, sediment, algae, colloids, etc., on the floor heating pipes, household faucets, electrical appliances, etc. to play a positive role in protecting.
Pre-filter is generally installed behind the water meter, the main role is to restore the tap water to the factory standard, to protect the downstream equipment.
The city's water supply pipeline is old and long, pipeline rust, sediment and other impurities will not only lead to brown water and water equipment control failure, such as faucet dripping (currently on the market pressure reducing valves are used than the column type, faucet spools using ceramic grinder type, fine particles within a short period of time will cause the failure of the pressure reducing valve, resulting in the grinder ceramic spools dripping) heat exchanger pipeline clogging, rupture, and the impurities will be in the pipe Precipitation, on the one hand, provides a breeding ground for bacteria, on the other hand, it will form electro-chemical compounds, they can cause corrosion or perforation of metal pipes in just a few months, the filtration accuracy of the pre-filter is 5-100 microns, which can filter impurities such as sediment, rust, floating matter and other impurities visible to the naked eye, and greatly prolong the service life of the subsequent equipment, such as faucets, showerheads, washing machines, water heaters, Toilet, etc. In Germany, the pre-filter legislation stipulates that all buildings after 1988 must be installed pre-filter, so the pre-filter is widely used in Europe and the United States market.
Pre-filter is a reliable impurity filtration device, can filter out more than 40 micron particles of impurities, so that the water quality is restored to the standard of tap water. Pipeline rust, sediment and other impurities will not only lead to brown water and water equipment control device failure (such as faucet dripping, heat exchanger pipe clogging, rupture, etc.). And will also be precipitated on the pipeline, on the one hand, for the breeding of bacteria to provide a breeding ground, on the other hand, will form electrochemical substances, they can be in just a few months to cause corrosion or perforation of metal pipes.
The pre-filter is suitable for both home installation and stand-alone installation upstream of the following equipment or systems to play a positive protective role, such as: water purifiers, dishwashers, coffee makers, water heaters, boilers, washing machines, underfloor heating, radiators, central air-conditioning, cooling towers, motors, hospitals, agricultural garden irrigation (e.g., micro-irrigation, drip irrigation systems) and so on. It can prevent water pollution and avoid pipeline corrosion.
