ANRM type multi-media mechanical filter adopts switch control to complete the process of water preparation, backwashing and washing.

The equipment is made of carbon steel or stainless steel and equipped with valves to control the switching and flow of water flow. The equipment is an important equipment in water treatment process with reasonable design and simple operation. It is used for pretreatment of soft water and pure water required by various industries and domestic water treatment. working principle

Filtration means that the raw water intercepts and absorbs various impurities, organic or inorganic substances, bacteria, viruses and microorganisms in the water through the filter layer of various filter materials. After filtration, the turbidity of the raw water will be reduced. At the same time, the organic or inorganic impurities, bacteria, viruses, oil, etc. in the raw water will be largely removed along with the reduction of turbidity, strengthening the subsequent disinfection effect. Because the removal rate of suspended solids and other impurities is improved, the amount of disinfectant can be reduced; In addition, the subsequent ion exchange, adsorption, membrane process and other treatment devices are not often blocked, so as to improve their treatment efficiency.

The mechanical filter is composed of tank body, valve and filter material. Its performance mainly depends on the filled filter material. The filter material is selected according to the inlet water quality and the purpose of the treated water. There are many kinds of filters. Our factory can provide the following types of filters:

1. Quartz sand filter: It is filled with various specifications of refined quartz sand, which is filled according to a certain grading. It is mainly used to remove suspended solid substances, fine particles and colloidal substances in water. It is an indispensable pretreatment equipment in water treatment. The filter can also be filled with manganese sand to remove iron and manganese ions in water, so as to achieve the purpose of water purification.

2. Activated carbon filter: it is filled with activated carbon, which has a large specific surface area and strong adsorption capacity. It can remove and absorb more than 99% of free chlorine, heterochromatic, peculiar smell, odor, etc. in the water. Through backwashing, it can remove organic or inorganic impurities, microorganisms and bacteria. It is often used in combination with quartz sand filter. It is an indispensable conventional equipment for water treatment engineering and is widely used.

3. High-efficiency fiber filter: using fiber as the filter material, it can intercept the tiny suspended solids that are not easy to precipitate and remove. The fiber filter material has the advantages of small resistance, high flow rate, high filtration accuracy, and long service life. The filter material can be backwashed and regenerated, and is widely used in high standard water in oil fields, chemical, electric power, metallurgy and other industries; Recycle, bypass filtration, wastewater recycling and reverse osmosis.

4. Multi-media filter: filled with various specifications of quartz sand and anthracite, mainly used to remove suspended solids and fine particles in water, with high flow rate and large water treatment capacity.
