Juntai Issues Operational and Maintenance Guidance for Tube Settlers

Hangzhou Juntai Plastic Products Co., Ltd., a manufacturer of environmental protection equipment, has published a technical guide detailing best practices for the operation and maintenance of tube settlers. The guidance outlines seven critical points aimed at maximizing the efficiency of water treatment processes and extending equipment lifespan.

Key recommendations include maintaining an optimal installation angle between 55-60 degrees to ensure effective settling and prevent sludge roll-up. Angles exceeding 65 degrees can lead to operational issues. Recommended flow velocities range from 0.5 to 1.2 cubic meters per hour per square meter, varying with turbidity, to prevent particle carryover.

The guide also stresses the importance of material selection, suggesting UV-stabilized PVC for outdoor applications while advising against ABS plastics in environments with a pH above 9.5. Regular cleaning cycles, such as backwashing every 72-120 hours based on sediment load, are crucial for sustained performance. High-pressure cleaning (over 3 bar) should be avoided to prevent damage to lamella plates.

An accompanying case study from a dairy facility illustrated the impact of incorrect setup. Tube settlers installed at a 70-degree tilt experienced a 42% drop in efficiency. Adjusting the angle to 58 degrees and installing 50mm sludge hoppers restored Total Suspended Solids (TSS) removal rates to 91%, highlighting the critical need for precise adjustments and maintenance.
