Mechanical filter


Mechanical filters, also known as pressure type filter. Is the preparation of pure water pretreatment, water purification system is an important part of. Materials are steel rubber lining or stainless steel, according to the filter media of different natural quartz sand filter, multi media filter, activated carbon filter, manganese sand filter, according to water can be divided into single flow filter, double flow filter, according to the actual situation may be used in combination can also be used alone.

Classification and characteristics:

Single flow mechanical filter pipe is simple, smooth operation. Filtration velocity is around 4 - 50m/n, operation cycle generally for 8 hours. Double flow mechanical filter upper end and the lower end is provided with a water inlet device, is arranged in the middle of the water outlet device. The utility model has the advantages of is filtered water, a higher decontamination capability, long operation cycle, generally 20 hours. The disadvantage is that the pipeline system is complex, operation is not stable, refueling washing more difficult.

Working principle:

Mechanical filter is to use one or several filter media, under a certain pressure, the liquid through the media, removal of impurities, filtering so as to achieve the purpose. The built-in filler generally: quartz sand, anthracite, porous ceramic particles, manganese sand, the user can choose according to the actual situation to use. Mechanical filters is mainly using the filler to reduce the water turbidity, interception in addition to the District of suspended solids in water, organic matter, colloidal particles, microorganism, chlorine odor and some heavy metal ions, and make the water processing is one of the traditional methods of water purification.

Application range:

Mechanical filter is widely used in water treatment process. It is mainly used for water treatment turbidity removal, reverse osmosis and ion exchange softening in salt system of pre treatment, can also be used for surface water, groundwater in addition to sediment influent turbidity is required to be less than 20 degrees, the effluent turbidity can be 3 degrees below.
