1)Wide Applicability
1.Suitable for sludge treatment across industries including municipal wastewater,food&beverage,chemicals,leather,welding materials,papermaking,printing&dyeing,and pharmaceuticals.
2.Effective for dewatering both high-and low-concentration sludge.For low-concentration sludge(≥2000 mg/L),it eliminates the need for concentration tanks or storage ponds,reducing construction costs,phosphorus release,and anaerobic odor generation.
2)Compact Design
1.Integrated structure incorporating the control cabinet,metering tank,flocculation mixing tank,and dewatering unit.
2.Small footprint for easy maintenance and component replacement;lightweight design simplifies transportation.
3)Anti-Clogging Performance
1.Self-cleaning capability eliminates the requirement for frequent filter gap flushing,minimizing water consumption and internal circulation load.
2.Highly effective for dewatering oily sludge.
4)Low-Speed Operation
1.Screw shaft rotates at 2–3 rpm,ensuring extremely low power consumption.
2.Minimal malfunctions,low noise/vibration,and safe operation.
5)User-Friendly Operation
1.Automated 24-hour continuous unmanned operation via interconnection with dosing systems,sludge feed pumps,and chemical pumps through the control cabinet.
2.Short daily maintenance time with simplified procedures.
6)Durability
1.Constructed almost entirely from stainless steel to maximize lifespan.
2.Only the screw shaft and moving rings require periodic replacement,offering extended service intervals.
Disadvantages of the Screw Press:
In terms of model selection, different countries have not yet made clear standards for Screw Press. Many manufacturers have different models, different equipment processing capabilities, and different prices. Customers cannot normally choose the right equipment of the same model, which is inconvenient in selection
