Discs plate filter automatic backwash water filtration complete appliance

Advantages and characteristics

1. Consistant filtering efficiency. As core element of filter, te unifomity of groove style filtering superposition piece reaches to international first rate standard. The filter is in effect for all kinds of suspension impurity including inorganic an organic impurity.

2. Standardized module, save, occupied sapace. The commutativity of every filtering unit element and intrface guarantees variety of filter combination. Customer may choose in accordance with actual demand. The system is compact and saves occupied space.

3. High efficency backwash energy and water saving. The unit of backwash will be finished for 7~20 sec only.In general the amount of cousumed water in backwash is less than 0.5% of amout filtering water. For viscosity impurity, high effective washing can also be reached. The suitable scope is wide.

4. Full automatic control flow continuously. The filtering and backwash may be carried out at the same time. The loss of prsure and flow rate produced by automatic maintenance of system is less. The backwash is carried out in turn one by one and the others work normally.

Principle at filtering phase

Stream will enter into the inner of filter through water inlet of filter. While water passes through filtering superposition piece, under the action of spring and hydraulic thefiltering superposition piece will be pressed closely and impurity granule will be withheld at crossing of filtering superposition piece. The fitered water will flow out through main canel. At this time one-way diaphragm valve is at open site.

Principle of backwahsh phase

While the pressure difference reaches to certain value or within the set time, the system will enter into backwash state automatically. Controller will control the valve to change the direction of stream. The one-way diaphragm valve at the bottom of filter wll close main canal and water of backwash will enter into the canal of four-group shower nozzle. Water pressure in the cavity of piston connected with shower nozzle canal will rise.The piston will move towards up and overcome the pressure caused by spring and release the space of piston at the top of filtering superposition piece group. Meanwhile backwash water will eject along the tangential diretion of 35x4 shower nozzle above th canal of four-group shower nozzle at high speed. It makes the filtering superposition piece piece rotate and separate. The ejecting water will wash the surface of filtering superposition piece and throw off impurity on it. While backwash is finished, the direction of stream will be changed again and the filtering superposition piece will be pressed closely and the system will enter into filtering state.

Main use of product and solution

1. Full flow or bypass filtering f circulating water for cooling tower

It can solve the block problem effectively and reduces energy consumption and dosing amount too and prevent from stopping caused by trouble and reduce the expense of system maintenance.

2. Intermediate water reuse, sewage pre-treatment

Save total amount of water to be used and improve the quality of water and reduce or avoid sewage discharging directly to lead environmenta pollution.

3. Pre-treatment of seawater desalination

Remove impurity and ocean mironorganism in seawater. The property of salt resistant and anti-corrosion of plastic filter is better than metallic filter with expensive cost.

4. Primary filtering before super filtering an reverse osmosis membrane

The purpose of protecting precision element of filter and prolonging its life can be reached.
