Automatic backwash aqua sand filter for drip irrigation system

Principle description

 When the system enters the state of filtering, pressurized water flows into the water distribution systems and being evenly distributed in the filtering material layers, which will intercept those suspended solids of the water. Water collector, which lies at the bottom of the filter, collects all the purified water and then let it out.

    With the accumulation of the impurities at the filtering material layers, the loss of pressure increases. When the pressure difference increases to a certain value or reach the preset cleaning time, the system will automatically switch to the backwashing mode. Then pressurized water from water-collection devices flows into and scours the filtering material layer, so that those intercepted impurities are discharged. The backwashing process lasts at least 2 minutes, and then the system will automatically turn to the filtering status.

DMF filter’s backwashing system includes three ways: manual, semi-automatic and fully automatic, respectively started through the manual button, PLC, the pressure difference or management system. Backwashing period and time are adjustable, which are prefixed as 3 minutes. This adjustment can be realized by the DLFCS automatic filtering control system, and users can also choose the PLC control system to meet their high requirements of centralized or remote communication control.

Parameter

(Note: Many sets in parallel can gain more flow

DMF60-4 mean there are 4 filtration tanks of 1500mm diameter in parallel)
