Chinese wholesale Fine Screening In Water Treatment - Recirculating Aquaculture System Fish Farming Aquaculture Drum Filter – Holly

Product Description

The drum filter is mainly composed of four parts: tank component, roller component, backwash component and liquid level automatic control component. It is made of non-toxic seawater corrosion-resistant high-quality engineering plastic materials. A stainless steel filter screen is fixed on the rotatable drum, and the tiny suspended substances in the water are separated and filtered through the screen and finally achieve solid-liquid separation. During the filtering process, small suspended particles in the water will cause the screen to be blocked. When the screen is blocked, the liquid level automatic control component works, and the backwash water pump and roller reducer automatically start working to make the screen timely cleaning to keep the equipment in good working condition.

Our company’s drum filter is designed for the problems that the existing filters cannot work automatically, is not resistant to corrosion, the screen is easy to break, easy to block, equipment failure rate is high, and maintenance and operation are difficult. It is one of the solid-liquid separation technologies in the early stage of water treatment in the aquaculture system. This product purifies the water by separating the solid waste in the aquaculture water to achieve the purpose of recycling.

Working Principle

When the water containing tiny suspended substances enters the roller, the tiny suspended substances are intercepted by the stainless steel screen, and after filtering, the water without suspended substances enters the reservoir.When the suspended substances in the roller accumulates to a certain amount, it will cause the water permeability of the screen to decrease,causing the water level in the roller to rise. When the water level rises to the set high water level, the liquid level automatic control component works. At this time, the backwash water pump and the roller reducer automatically start working at the same time.

The high-pressure water of the backwash water pump is subjected to high-pressure cleaning of the rotating screen. After washing,suspended substances flows into the dirt collection tank and is discharged through the sewage pipe.After the screen is cleaned, the water permeability of the screen rises and the water level drops. When the water level drops to the set low water level, the backwash water pump and the roller reducer will automatically stop working, and the filter will enter a new a working cycle.
