Introduction
Gravity-type valve-free filter selection of steel-based, non-toxic coating anti-corrosion. In the factory prefabricated and assembled into several parts, transported to the scene, the factory staff to continue welding, after repeated anti-corrosion delivery to the construction unit to take over, after loading filter, they can put into trial and operation, greatly shorten the construction Cycle, factory production, not affected by the construction season.

working principle
Raw water through the high water tank U-shaped inlet into the filter, from top to bottom through the filter layer after filtration into the clear water area, filled through the outlet pipe. The water level to the siphon auxiliary pipe nozzle, the water from the tube down, through the suction pipe to take the siphon down the air, when the vacuum When the degree reaches a certain value, the effect of siphoning occurs so that the water from top to bottom through the filter layer on the filter backwash. When the water tank drops down to the siphon bad tube, the air enters the siphon, destroys the siphon effect, the backwash is finished, and the filter starts again.

Applications
1. Side-filtering treatment of industrial recycling cooling water in petroleum, chemical, metallurgy, electricity, oil refining, light industry, textile, and other industries.
2. In purifying surface water and eliminating iron and manganese from groundwater.
3. Filtration treatment of waterworks.
4. In the pretreatment of softening and desalination treatment.
5. In the purification treatment of swimming pool and fountain waterscape.
6. To remove suspended matters from production wastewater.
