What are the application areas of the pre-filter?
The pre-filter is generally installed behind the water meter, and its main function is to restore the tap water to the standard before leaving the factory and protect downstream equipment.
The city’s water supply pipelines are old and long. The rust, silt and other impurities in the pipelines will not only cause brown water and water equipment control failure, such as faucet dripping (currently all pressure reducing valves on the market are proportional, and the valve core of the faucet is made of ceramic Grinding type, small particles will cause the pressure reducing valve to fail in a short time, causing the grinding plate ceramic valve core to drip) The heat exchanger pipe is blocked and ruptured, and impurities will settle on the pipe, which provides for the growth of bacteria. In addition to the hotbed, on the other hand, electrical compounds will be formed. 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 the impurities seen by the naked eye. Impurities such as sand, rust, and floating objects greatly extend the service life of subsequent equipment, such as faucets, showers, washing machines, water heaters, toilets... Pre-filter legislation in Germany stipulates that pre-filters must be installed in all buildings after 1988, so pre-filters are widely used in the European and American markets.
In order to kill bacteria, we generally use the method of boiling, but this method cannot eliminate the insoluble solid impurities and harmful chemicals, such as rust, sand, free residual chlorine and its compound trichloromethane (carcinogen ).
The pre-filter is a reliable impurity filtering device, which can filter out particulate impurities above 40 microns and restore the water quality to the standard when tap water was shipped. Impurities such as pipeline rust, mud and sand will not only cause brown water and the failure of water equipment control parts (such as dripping from the faucet, blockage and rupture of the heat exchanger pipe, etc.). And it will settle down on the pipeline, on the one hand it provides a breeding ground for bacteria, on the other hand it will form electrochemical substances, which can cause corrosion or perforation of the metal pipeline in just a few months.
The pre-filter is not only suitable for home installation and use, but also suitable for independent devices upstream of the following equipment or systems to play a positive protective role, such as: water purifiers, dishwashers, coffee machines, water heaters, boilers, washing machines, floor heating , Heat sinks, central air conditioning, cooling towers, motors, hospitals, agricultural garden irrigation (such as micro-irrigation, drip irrigation systems), etc. It can prevent water pollution and avoid pipeline corrosion.
The product is generally small in size, does not require electricity, and does not need to be specially arranged for floor drains.
