Knowledge Base

Q

How to choose the correct rotary coarse grille cleaning machine In the sewage treatment process, effective interception of suspended solids is a key link to ensure the normal operation of subsequent treatment facilities. The traditional manual slag removal method is inefficient and labor-intensive, while the rotary coarse grid cleaning machine, as an automated pretreatment equipment, can continuously and automatically remove large suspended impurities in sewage. However, facing the market

Q

In drainage, industrial wastewater treatment and urban flood control and drainage systems, the incoming water often carries a large number of coarse floating debris, such as branches, plastic bottles, cloth strips, weeds, foam, etc. If not intercepted in a timely manner, these impurities can easily cause entanglement of the water pump impeller, pipeline blockage, valve jamming, and even lead to equipment shutdown or waterlogging risks. Traditional fixed grilles rely on manual slag removal, which has low efficiency, poor performance, and is difficult to achieve

Q

In sewage treatment systems, especially in situations where high effluent quality is required, conventional coarse grids are difficult to effectively intercept suspended solids with smaller particle sizes, such as small plastic fragments, fibers, algae, food residues, etc. If these tiny impurities enter the subsequent processing unit, they may cause membrane module blockage, aeration system scaling, or affect sedimentation and disinfection efficiency. Rotary fine grid cleaning machine as a deep
