Semi-Automatic Filter Press for Municipal Wastewater Sludge

Municipalities and community wastewater treatment plants (WWTP) face escalating pressures: increasing sludge volumes, stringent environmental regulations, and tight operational budgets. Our Plate and Frame Filter Press delivers a cost-effective, high-efficiency sludge dewatering solution designed specifically for municipal and community-scale applications. By transforming liquid sludge into solid, disposable cake, our system reduces transport costs, simplifies disposal, and ensures compliance with environmental standards—making it the ideal choice for public utilities and community infrastructure projects.

• Scalable for Community Needs: Modular designs adaptable for small communities (5-20 tons/day) to large municipal plants (100+ tons/day). Compact footprint ideal for retrofitting existing WWTP facilities without major construction.
• Public-Sector Durability: Heavy-duty steel frame and corrosion-resistant polypropylene plates withstand 24/7 operation in humid, abrasive environments. Designed for long service life (20+ years) with minimal maintenance, reducing lifetime costs for public budgets.
• Operator-Friendly Automation: Simple PLC interface allows operation by municipal staff with minimal training. Automated cycles (filling, pressing, cake release) reduce labor costs and human error.
• Community-Sensitive Design: Enclosed structure with optional odor control covers for urban or residential-nearby installations. Low-noise operation compliant with municipal noise ordinances.
• Regulatory Ready: Consistently produces cake with 25-40% dryness meeting landfill disposal or agricultural reuse standards. Comprehensive documentation support for environmental compliance reporting.

• High-Volume Processing: Optimized chamber designs and feed systems handle large volumes of biological sludge from activated sludge processes.
• Advanced Filtration: Proprietary filter cloth materials resist blinding with fibrous municipal sludge.
• Water Recycling: Filtrate water quality suitable for direct return to WWTP headworks.
• Winterization Options: Cold-weather packages for outdoor installation in northern climates.

• Thickened Sludge Receiving: Accepts sludge from gravity thickeners or digesters (0.5-3% solids).
• Polymer Conditioning: Automated polymer dosing system optimizes dewatering efficiency.
• Pressure Filtration: Sludge pumped into chambers at 15-25 bars; filtrate returns to treatment process.
• Cake Formation: Produces solid cakes with 30-45% solids content—stackable and ready for disposal.
• Automated Cleaning: Optional high-pressure wash system maintains performance between cycles.

• Public Wastewater Treatment Plants: Primary and secondary sludge dewatering
• Community Sewage Systems: Cluster developments, suburban municipalities
• Public Infrastructure Projects: Government-funded water improvement initiatives
• Sewage Collection Networks: Treatment of sludge from multiple collection points
• Environmental Remediation: Contaminated sediment dewatering in public works projects
