Advantage of Filtering System

Advantage	Characteristic
Constant filtering efficiency	As core element of filter, the uniformity 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 and organic impurity.
High efficiency backwash, energy and water saving	The unit of backwash will be finished for 7-20 sec only. In general the amount of consumed water in backwash is less than 0.5% of amount of filtering water. For viscosity impurity, high effective washing also be reached. The suitable scope is wider.
Full automatic control, flow continuously	The filtering and backwash may be carried out at the same time. The loss of pressure 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.
Low cost, reliable and long service life System	The system has been identified through IS9002 international quality system. And all the products are tested overall before sold. It's almost without daily maintenance, installation and convenient operation, reliability transportation.

 
Filtration System's Application

Application	Description	Function	Industry
Cooling circulating water treatment	Cooling water equipment, instruments and products cooling water	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.	Steel and iron, power plant, petrochemical, plastic, running water primary filtration, machinery, etc
Membrane water treatment	Membrane system protection	The purpose of protecting precision element of filter and prolonging its life can be reached.	Water treatment
Water treatment	Spraying water treatment, protection granulated substance ponders, filter element, filter pocket, ion-exchange reactor, etc.	Save total amount of water to be used and improve the quality of water and reduce or avoid sewage discharging directly to lead environmental pollution.	Electric power, chemical, automotive, paper-making and other industries
Seawater filtration	Pre-treatment of seawater desalt	Remove impurity and ocean microorganism in seawater. The property of salt resistant and anticorrosion of plastic filter is better than metallic filter with expensive cost. And prolong its lift.	Water treatment
Other chemical fluid	Solvent, emulsion, etc.	Meet the production requirements. Protect equipments.	All industries
Drip irrigation filtration	Cotton, fruit trees drip irrigation filter	Protect drip outlet	Large areas of crops land

 
Main Use of Product and Solution:
1. Full flow or bypass filtering of circulating water for cooling tower:
It can solve the block problem effectively and reduces engergy 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 tolal amount of water to be used and improve the quality of water and reduce or avoid sewage discharging directly to lead environmental pollution.
3. Pre-treatment of seawater desalt:
Remove impurity and ocean microorganism in seawater. The property of salt resistant and anticorrosion of plastic filter is better than metallic filter with expensive cost.
4. Primary filtering before super filtering and reverse osmosis membrane:
The purpose of protecting precision element of filter and prolonging its life can be reached.
5. Main applied industries:
Chemical industry, electric power, mechine building, processing of foodstuff and drinking, plastic, paper-making, mining, metallurgy, textile, petrochemical, environment, golf course, agricultural water saving, automobile, tap water, etc.
 
Working Principle for Superposition Piece Disk Style Filter
    The filtering superposition piece is a carrier for the mixture treatment. It superimposes by a group of a double-sided belt different direction trench's plastic disk sheet. While water passes through filtering superposition piece, under the action of spring and hydraulic the filtering superposition piece will be pressed closely, then they'll form numerous crossing of superposition piece. And impurity granule will be withheld at those crossing. The width of lamination is 12-14mm. It's made of high-quality engineering plastic, high wear resistance. Filtration accuracy depends on the depth and number of grooves.
 
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 the filtering superposition piece will be pressed closely and impurity granule will be withheld at crossing of filtering superposition piece. The filtered water will flow out through main canal. At this time one-way Diaphragm Valve is at open state.

Our factory introduction:
We:Changzhou Duoling Water Treatment Factory established in 1996. Our factory is located in jiangsu province of China, covering an area of 15,000sqm. We mainly manufacture disc filtration system, two position three -way valves, plastic hydrauliccontrol valves and plastic flow meters. With the modernized workshop, advanced mechanical equipment and competent staff , we provide high-quality products that have been well applied in industry, agriculture and environmental engineering. Many of our products have been exported abroad such as South-East Asia, Europe, Australia and Indonesia.
Our disc filters and two-position three-valves can fulfill different water treatment projects. Compared with traditional Water Filters, the disc filter can save water and do excellent backwash and the weight is much lighter. It is more economical, high automatic, and space- saving.
Our factory holds the idea of "striving for excellence, customers oriented". Welcome your partnership and cooperation with us. We will provide you with the best products and the most professional service.
