200-400V Plate And Frame Filter Press For Sewage Treatment / Wastewater Treatment

Plate and Frame Filter Press: Used for dewatering treatment of industrial wastewater, surface treatment wastewater, and wastewater containing impurities/suspended solids.

Quick Details

The plate and frame filter press is a kind of pressure filtration equipment operated intermittently. Its core working principle is that the suspension is pumped and forced into the filter chamber composed of multiple alternately arranged filter plates and filter frames by a high-pressure pump. With filter cloth as the filtration medium, solid-liquid separation is achieved under pressure. Solid particles form filter cakes with extremely low moisture content that remain in the filter chamber, while clear filtrate penetrates the filter cloth and is discharged.

Main Components

Frame:A robust steel structure that provides a stable foundation for the operation of the equipment.

Filtration Unit:Composed of multiple filter plates and filter frames, it serves as the core working area of the equipment. Optional materials include reinforced polypropylene, cast iron, or stainless steel to adapt to different corrosive environments.

Filter Cloth:A variety of materials (polyester, nylon, polypropylene, etc.) and weaving processes are available to achieve optimal filtration efficiency and service life based on the characteristics of different materials.

Hydraulic System:Provides power for clamping and pulling the filter plates, ensures no leakage during high-pressure filtration, and enables automated operation.

Electrical Control System:PLC control can be adopted to realize the automatic cycle of the entire process including clamping, feeding, pressing, and discharging, featuring simple operation and labor saving.

Key Technologies and Performance Advantages

Ultra-high Filter Cake Solids Content:Thanks to its unique chamber structure and the subsequently available diaphragm squeezing function, secondary high-pressure extrusion can be achieved. The final moisture content of the filter cake can be 5-15% lower than that of ordinary centrifuges or belt filter presses. This means:

A significant reduction in sludge disposal volume, directly cutting down transportation and landfill/incineration costs.

The filter cake can be easily further recycled and utilized (e.g., as fuel or raw material for building materials).

Excellent Filtrate Clarity:With high filtration precision, the filtrate is clear and can be directly reused in the production process or meet strict discharge standards, realizing water resource recycling and environmental compliance.

Unmatched Adaptability and Flexibility

Wide Material Adaptability: It can effectively handle materials ranging from hard-to-filter fine and viscous substances (such as municipal sludge and chemical waste) to coarse particle slurries (such as mineral tailings and ceramic raw materials).

Flexible Processing Capacity: The filtration area and processing capacity can be easily adjusted by increasing or decreasing the number of filter plates, meeting the diverse needs from small-scale laboratory tests to large-scale industrial projects.

High-pressure Resistant Design: The working pressure can usually reach 1.0-2.0 MPa or even higher, ensuring high efficiency even when dealing with high-difficulty materials.

Low Operation and Maintenance Costs

Extremely Low Energy Consumption: Electricity is only consumed during feeding and pressing, resulting in significantly lower energy consumption compared with continuously operating centrifuges.

Low Operating Costs: No expensive flocculants are required (or the dosage is minimal), and the main consumable is filter cloth, which has a long service life and is easy to replace.

Robust Structure and Easy Maintenance: The core components are durable with low failure rates, and daily maintenance work is simple.

Typical Application Fields

Chemical and Pharmaceutical Wastewater:Treat wastewater containing chemical precipitates, catalyst particles, high-chroma or highly toxic substances. The separated sludge can be disposed of safely.

Electroplating and Metal Surface Treatment Wastewater:Highly efficiently dewater metal hydroxide-containing sludge (e.g., ferrite sludge, mixed precipitation sludge) generated after heavy metal treatment via chemical or electrolytic methods. It is a key step to achieve stabilization and reduction of heavy metals.

Textile Printing and Dyeing & Leather Wastewater:Treat dye sludge from coagulation-sedimentation processes and organic-inorganic sludge from leather tanning wastewater, yielding filter cakes with high dryness.

Papermaking Wastewater:Conduct deep dewatering of pulp fiber sludge and deinking sludge after air flotation or sedimentation processes, significantly reducing sludge volume.

Food Processing Wastewater:Treat excess sludge produced from biochemical or coagulation treatment of wastewater containing organic matter (e.g., protein, starch, fat). Dewatered sludge facilitates subsequent disposal or resource utilization attempts.

Sand Washing, Stone & Ceramic Processing Wastewater:Core application in treating production wastewater with extremely high suspended solids content (e.g., stone powder wastewater, clay wastewater). It achieves complete mud-water separation, and the clarified water can be reused in production, forming a closed-loop system for zero discharge.

Mining Leachate and Mineral Processing Wastewater:Treat complex-component sludge formed after neutralization-sedimentation of acidic wastewater from mining operations or tailings water from mineral processing.

Industrial Park Comprehensive Wastewater:Suitable for the final dewatering disposal of mixed sludge generated from centralized wastewater treatment plants after biochemical or physicochemical treatment.
