The Role of Frame Filter Presses in Modern STP Sewage Treatment Plants
2025-08-25Sewage Treatment Plants (STP) are critical infrastructure for urban and industrial environments, addressing both environmental protection and sustainable resource management. As a leading supplier of dewatering equipment, we specialize in integrating frame filter press technology into comprehensive STP solutions, particularly for efficient sludge treatment and resource recovery.
The plate and frame filter press serves as a core component in the sludge dewatering stage of STP operations. It operates through a series of recessed plates and frames that apply high pressure to separate solids from liquids, significantly reducing sludge volume and facilitating compliant disposal or reuse.
Key Features & Advantages of Our Frame Filter Press in STP Applications
1. Exceptional Dewatering Efficiency
Our frame filter press achieves outstanding solid-liquid separation, producing filter cakes with moisture content as low as 60%. This greatly reduces sludge volume, cutting transportation and disposal costs.
2. Robust Construction for Demanding Environments
Built with high-tensile strength materials and corrosion-resistant coatings, our filter presses withstand aggressive sewage sludge compositions, ensuring long service life and minimal maintenance.
3. Automated Operation with Intelligent Controls
Modern PLC systems enable fully automated filter press operation, including plate shifting, cake discharge, and cloth washing. This reduces labor requirements and enhances process consistency.
4. Adaptability to Various Sludge Types
Whether processing municipal wastewater sludge or industrial effluent, our filter presses handle diverse sludge characteristics with adjustable pressure settings and cycle times.
5. Energy-Efficient Design
Optimized hydraulic systems and efficient pumping arrangements minimize power consumption, contributing to lower operational costs and environmental impact.
6. Closed-System Operation
The enclosed design contains odors and prevents spillage, maintaining hygienic conditions and meeting stringent environmental regulations.
System Integration: Frame Filter Press within Complete STP Solutions
In modern STP sewage treatment plants, the frame filter press doesn't operate in isolation but as part of an integrated treatment train:
Pretreatment Stage: Screening and grit removal to protect downstream equipment
Biological Treatment: Activated sludge processes or MBR systems for organic matter breakdown
Clarification: Settlement of biological solids
Sludge Thickening: Concentration of sludge before dewatering
Dewatering Stage: Frame filter press for volume reduction
Disinfection: Final effluent treatment before discharge or reuse
Our expertise ensures seamless integration of the filter press with other STP components, optimizing overall plant performance.
Case Studies
-
Case Study 1: Municipal Wastewater Treatment Plant Upgrade
A municipal wastewater treatment plant, using traditional dewatering equipment, faced significant challenges with high sludge disposal costs. The plant treated approximately 20,000 cubic meters of domestic wastewater daily.
Solution: Two automated plate and frame filter presses were installed, each with a filtration area of approximately 150 square meters.
Results:
Achieved consistent filter cake density and a solids content of 65% (compared to 20% with the previous equipment).
Sludge volume was reduced by 70%, significantly reducing disposal costs.
Automated operations reduced personnel requirements by 50%. The resulting return on investment (ROI) was achieved within 18 months due to reduced disposal costs.

Case Study 2: Industrial Park Wastewater Treatment
An industrial park treated mixed wastewater from various manufacturing plants, including chemical, textile, and food processing.
Solution: A custom-designed STP equipped with specialized plate and frame filter presses capable of handling a wide range of sludge characteristics. Results:
Successful treatment of complex industrial wastewater streams
Filter cake passes leachate testing and is safe for landfill disposal
85% water recovery for industrial use
Meets stringent provincial discharge standards
