Drum filter introduction

The automatic box type rotary drum filter is mainly composed of box components, drum components, back cleaning system and electric control box. The treatment capacity can be customized according to demand, and it’s made of non-toxic, corrosionresistant and environmental protection materials.SS316L filter screen is used to separate suspended solids in water. When the water containing suspended solids enters the drum, the suspended solids are intercepted by the stainless steel filter screen, and the water without suspended solids enters the reservoir after filtration. When the suspended solids in the drum accumulate to a certain amount, it will cause the water permeability of the filter screen to drop, resulting in the rise of the water level in the drum.The liquid level automatic control system works. At this time, the back cleaning water pump and the drum motor are automatically opened at the same time. The high-pressure water output from the back cleaning water pump cleans the rotary drum filter screen and the cleaned suspended solids flow to the wastewater collection tank under the high-pressure water washing and are discharged through the wastewater pipe.When the filter screen is cleaned, the water permeability of the drum filter screen rises and the water level in the drum drops. When the water level drops to the set low water level, the backwashing water pump and the drum motor will automatically stop working, and the drum filter will enter a new round of working cycle.TPA:20-150m3/HTPK: 200-500m3/H
