Pre-filter

Pre-filter

The pre-filter is the first coarse filtration device for water in the whole house. It can filter large particles such as sediment and rust in tap water. The pre-filter is usually installed at the front end of the pipe, so it is named after the word "front"; and "filtering" refers to the basic principle of such equipment.

Introduction

The pre-filter is usually a "T" type structure. The left and right ends of the "one horizontal" position above are the inlet and outlet. The "one vertical" position below is the cylindrical filter inside the fuselage and the inside, and the lowermost end is the sewage outlet, which is controlled by a valve to open and close.
The accuracy range of the filter varies from 5 to 300 microns depending on the brand and model. Mainly removes the sediment impurities and bacteria, microbial residues, rust, sand mud and other particulate impurities larger than 5 microns to avoid damage to the human body and skin; and to downstream pipelines, water purifiers, water heaters, washing machines, high-grade The faucet and shower have a positive protective effect. The pre-filter can also add the “phosphorus phosphate-reducing” scale-reducing filter to prevent the scale of solar energy and water heater.
Usually installed in the water meter of the inlet pipe to ensure that a large amount of sediment impurities generated in the pipe network will not cause harm to the human body, and it will play an active role in protecting the dark pipe, faucet and electrical appliances. The pre-filter is a secondary polluted nemesis and is a reliable impurity filtering device.

Main role

Filter the sediment, rust, and large particulate matter in tap water. Preventing a large amount of sedimentary impurities generated in the water supply network of cities and communities from causing harm to the human body, and for dark pipes, faucets, plumbing, water heaters, boilers, central air conditioners, washing machines, dishwashers, coffee machines and other water appliances (clean water) Machines, pure water machines, water softeners, etc. play an active role in pre-protection.
The pre-filter is the nemesis of the secondary pollution of the water supply pipe network, which restores the water quality of the household to the factory standard of tap water. It is a reliable impurity filtering device and the first clean water guard in your home.
Remove visible solid impurities in the pipeline, mainly rust, silt, algae, colloid, etc., and play an active role in protecting the floor heating pipes, household faucets, electrical appliances, etc.

Application field

The pre-filter is usually installed behind the water meter. The main function is to restore the tap water to the factory standard and protect the downstream equipment.
The city's water supply pipeline is old and long, and the pipeline's corrosion, sediment and other impurities will not only cause brown water and water equipment control failure, such as faucet dripping (the pressure reducing valves on the market are all in series, the faucet valve core is made of ceramic grinding The chip type, the small particles will cause the pressure reducing valve to fail in a short time, causing the grinding ceramic valve core to drip. The heat exchanger pipe is blocked and broken, and the impurities will precipitate on the pipe, which provides a breeding ground for bacteria. Hotbeds, on the other hand, form compound compounds that can cause corrosion or perforation of metal pipes in just a few months. The pre-filter has a filtration accuracy of 5-100 microns and can filter impurities such as mud seen by the naked eye. Sand, rust, floating objects and other impurities, greatly extend the service life of subsequent equipment, such as faucets, showers, washing machines, water heaters, toilets. Pre-filters in Germany require that pre-filters be installed in all buildings after 1988, so pre-filters are extremely widely used in the European and American markets.
In order to kill bacteria, we generally use the method of boiling, but this method can not eliminate impurities and harmful chemical substances that are insoluble in water, such as rust, sand, free residual chlorine and its compound chloroform (carcinogen ).
The pre-filter is a reliable impurity filtering device that filters out particulate impurities above 40 microns to restore water quality to the standard for tap water. Corrosion, sediment and other impurities in the pipeline will not only cause brown water and water equipment control failures (such as faucet dripping, heat exchanger piping clogging, cracking, etc.). It also precipitates on the pipeline, providing a hotbed for the growth of bacteria on the one hand and electrochemical substances on the other, which can cause corrosion or perforation of metal pipes in just a few months.
The pre-filter is suitable for home installation and is also suitable for independent installations in the upstream of the following equipment or systems, such as: water purifier, dishwasher, coffee machine, water heater, boiler, washing machine, floor heating , heat sinks, central air conditioning, cooling towers, motors, hospitals, agricultural park irrigation (such as micro-irrigation, drip irrigation systems). It can prevent water pollution and avoid corrosion of pipelines.
The product is generally small in size, does not require electricity, and does not need to be specially arranged for floor drain.
