Many medium filter filter material harden reason analysis

I company specializing in the production of medium filter manufacturers, production of many medium filter according to the types of control can be divided into manual and automatic. Manual type mainly through the adjustment of the valve to control the operation of the filter, is washed, backwashing; And automatic type is run to filter through the FLECK controller, is washed and backwashing, state control, according to the material of tank can be divided into the glass fiber reinforced plastic cans, carbon steel, stainless steel pot, pot wall can according to user requirements for internal coating or rubber lining anticorrosive epoxy coating.

medium filter ( Also known as mechanical filter) Is a layer of activated carbon, quartz sand, walnut shell, or other material for the bed, the top of the bed is composed of the lightest and most coarse grade material, the heaviest and the most fine grade material in the lower part of the bed. The principle of filter - based on depth - Larger particles on the top floor in water has been removed, depth of small particles in the filter medium is removed. So that the water quality reach standard after the coarse filtration.

more medium filter is to use one or several of filter medium, under certain pressure of high turbidity water by a certain thickness of granular or the grain materials, effectively to remove suspended impurities make water clear process, commonly used with quartz sand, anthracite coal, manganese ore, etc. , mainly used for water treatment in addition to the turbidity, soften water, pure water level before the pretreatment, such as water turbidity can be up to 3 degrees.

medium filter can remove more big particles suspended in water, and reduces the SDI value of the water, can satisfy the demands of deep purifying water quality. The device has low cost, low operating cost, simple operation; Filter material after backwashing, reusable, long service life of filter material, etc.

medium filter is widely used in water treatment process, mainly used for water treatment in addition to the turbidity, demineralized water, electrodialysis, reverse osmosis pretreatment before order, can also be used for surface water, groundwater, sediment removal, etc.

medium filter filter material more harden reason analysis

( 1) Trapped on the filter surface dirt, if in a certain period, can't effectively remove, in the subsequent backwashing process, if the wash air will lead to uneven distribution of highly heterogeneous, with backwashing rub moves in the air, the small rub momentum, oil and other impurities on the surface of the filter material can't effectively remove, in the next normal filter water cycle, local load increase, impurities from the surface into the internal, pellets increases gradually, and at the same time to filter for filling in the deep, until the whole filter failure. Note: in the actual operation and backwashing air often appear uneven phenomenon, is mainly due to the cloth at the bottom of the hole, the local filter cap blockage in the gas pipeline or damage caused or deformation of the grid tube spacing.

( 2) The surface of the filter layer filter material particles small, backwash less chance collide with each other, when the momentum is small, so it is not easy to clean. The sand to easy to form a small clay balls. When the end back flush filter to grading, mud ball into the lower level in the filter material, grew up as the mud ball is moving to the deep.

( 3) Raw water contained in oil, intercept, in the filter backwashing and residual part, accumulate over a long period, is the main factor lead to filter material harden.

when medium filter for backwashing more according to the water quality characteristics of raw water and effluent water quality requirements, using limited head loss, water quality standard to determine or filtering time, etc.

of the strength of gas medium filter gas washing: 15 l/M2S, gas pressure, 700 - More than 800 kpa
