Principle descriptions
As water flows into the filter cylinder from the inlet, impurities will be left on the inner wall of the cylinder while the purified water flows out. When the impurities accumulated to a certain number, or the pressure difference of the selfcleaning filter reaches a preset number, or the washing time arrived, the filter will start the selfcleaning processes, including two steps: First, open the automatic drain valve of the filter. Then, electronic motors drive the cleaning brushes which are inside the filter’s screen, so the impurities will be intercepted by the screen and discharged from the sewage valve. The whole working system is controlled by a smart control box equipped with the device, ensuring to automatically clean the filter without stopping water supply. The system has several control modes: pressure difference, time, manual and PLC control.
With the advantages of high filtration precision, short backwashing time, low water consumption and low pressure loss, automatic selfcleaning filters of DLD series are able to realize the following functions without stopping water supply: automatic cleaning and drainage, equipped with three operation functions, namely pressure difference, time and manual, to ensure you a stable and quality water supply.
Tips for your choosing products
When you are choosing self-cleaning filters, please consider the following parameters:
1, Processing flow capacity
2,Chemical properties of the filter medium
3, Suspended solids concentration of filter medium
4, Required filtering precision
5, Pipeline pressure

Application range
Industry filtration:
It is suitable for industry circulating water filtration, such as cooling or heating system, sewage treatment, sprinkler head protection, workshop and municipal water recycling, filtration before the R.O. system, papermaking, chemical industry, Babbitt disinfection system, vacuum pump system, air compressor system, continuous casting system, other water treatment applications and so on.
Irrigation filtration:
Filtration: groundwater, municipal water; rivers, lakes and sea waters. Applications for orchards, nurseries, greenhouses, golf courses, parks and so on.
To get the best filtration effect, improving water quality and protect irrigation systems,different types of filters should be combined according to different type of raw water used for irrigation.
| Raw water | Water quality | Typical solution | Filtration efficiency |
| Surface water | Turbidity and high organic content | Sand filter +self-cleaning filter | High flow rate, small occupied space |
| Sand filter+disc filter | Suitable for system with low flow; Large occupied space | ||
| Underground water | Large quantities of sand | Centrifugal filter+self-cleaning filter | High flow rate;complete blackwash,low cost |
| Centrifugal filter+disc filter | Suitable for system with low flow,complete blackwash,easy to install |
