Mechanical Pressure Filter

Mechanical Pressure Filter

Mechanical filter is a kind of pressure filter, generally used as water purification, tap water treatment, groundwater treatment and water reuse, sewage treatment and other mechanical filtration equipment. The filter medium of mechanical filter is divided into quartz sand filter, activated carbon filter, multi-medium filter, manganese sand filter (except iron and manganese filter), fiber ball filter, mechanical filter material is divided into stainless steel mechanical filter and carbon steel mechanical filter, etc.. Our company is a mechanical filter manufacturers, supply large and medium-sized cities such as Shanghai, nanjing, guangzhou, shenzhen, fuzhou, xiamen, nanchang, wuhan, changsha, Beijing, zhengzhou, chengdu, chongqing and southwest, northeast and north China, and freight logistics company supporting services.

Product Details

The principles and functions of the above mechanical filters are briefly described below:


1, quartz sand filter


Quartz sand filter is generally used as the pretreatment of pure water equipment and ultrafiltration equipment, it is mainly through the filter layer of sand, colloid, metal ions and organic matter for interception, adsorption. In the general water treatment commonly used, because of its pollution-free, low price, low operating cost, so it is widely used.


2, activated carbon filter


Activated carbon is a very small carbon particles per unit area has a large pore, usually we call it capillary pore. This capillary has a strong adsorption capacity, due to the large surface area of carbon particles, in full contact with impurities in water. These impurities can be adsorbed in micropores to remove impurities such as colloids in water. Activated carbon can also adsorb CL ions and ozone in the water, the organic matter in the water has a certain adsorption capacity, can obviously adsorb the pigment in the water, in the water treatment industry we generally require the iodine value of more than 700mg, such a strong adsorption capacity of activated carbon.


3. Multi-media filter


As the name suggests, multi-media filter is filled with more than two kinds of filter material is called the multi-media filter, the use of multi-media filter in water treatment, common multi-media filter material are: anthracite, ceramsite, quartz sand, activated carbon and so on. Particle size of the lower filter material is generally required to be smaller than that of the upper filter material, so as to ensure the effectiveness and full utilization of the lower filter material. The density of the upper layer should be small to ensure the recovery of the layer after reverse washing. If the density of the upper layer is small, the filter material from the upper layer will sink to the lower layer after reverse washing. Take the two-layer filter bed as an example, the upper layer is composed of the light filter material with the largest particle size and small density, such as anthracite and activated carbon. The lower filter material has small particle size and large density and is generally composed of quartz sand. The formation of the upper filter material from coarse filtration, resistance, head loss, the lower filter material from fine filtration, strong ability to cut pollution, so as to give full play to the role of multi-media filter bed, that is, head loss, good filtering effect characteristics, fully delivered the advantages of each layer.


4, iron and manganese filter


In addition to iron and manganese filter also known as manganese sand filter, mainly rely on its own manganese sand catalytic action, there is in the manganese sand filter material surface gradually formed a layer of iron filter film as an active filter film, can play a catalytic role. The newly generated iron oxide, as the active filter membrane material, also participates in the new catalytic iron removal process, so the iron removal process of the active filter membrane is an automatic catalytic process. Mainly used for groundwater treatment, circulating water treatment grade sewage treatment.


5. Fiber ball filter


Fiber ball filter, as the name suggests, is the inner fiber ball filter, is also a kind of pressure type mechanical filter, fiber ball filter in the fiber ball porosity accounts for about 93% of the filter material layer. Fiber ball filter running water into the bottom go to, because the water flow through filter layer, the resistance of the filter material formed on panasonic tight space structure of the ideal, not only flux is big, also increased the section carrying capacity, he effectively remove the suspended solids in the water, sediment, and organic matter in water, colloid, iron, manganese, etc have obvious removing effect, the product is applied in the fields of oily wastewater and the fine filter, filtration flux and fiber ball not sticky oil, so widely used in petrochemical industry.
