Import Dewatering Box Liners For Sludge Waste — Buy in wholesale FOB from Supplier in China

Dewatering box liners for sludge waste are heavy-duty polypropylene bags designed to contain and drain liquid from municipal and industrial sludge during dewatering operations. These liners are manufactured with a 120 gsm non-woven fabric base and a 150-micron polypropylene film lining, providing puncture resistance and chemical compatibility with typical sludge compositions including activated sludge, digested biosolids, and industrial wastewater residues. The dimensions are standard at 1.2 m wide by 1.5 m deep, with reinforced side seams and a 200 mm diameter bottom outlet valve for controlled drainage.

The material is UV-stabilized and rated for continuous contact with pH levels between 4 and 10, making it suitable for a broad selection of wastewater treatment environments. While the liner itself is not certified to ISO 14001, the manufacturing process follows standard industrial hygiene practices for textile-based containment products. Typical industry alternatives include woven polyethylene or polyester-based liners, but this product’s non-woven structure offers better filtration efficiency and lower cost per unit volume. The fabric is designed to allow water permeation while retaining solids above 50 microns, reducing the need for secondary filtration.

These liners are used by municipal wastewater plants, food processing facilities, and chemical manufacturers across Asia and Eastern Europe to reduce sludge volume before landfilling or incineration. Buyers typically order in batches of 500 to 2,000 units per shipment, packed in cartons of 50 units with moisture-resistant wrapping. Lead times vary based on production scheduling, and delivery is usually arranged under FOB Qingdao or CIF terms. Buyers should confirm compatibility with their dewatering box frame dimensions before placing orders.
