High Efficiency Electroplating Wastewater Filter Press

Electroplating wastewater is a byproduct of various stages in the metal finishing process. Characterized by its diverse sources and complex chemical composition, it poses significant environmental and health risks if not managed correctly. As the core machine for solid-liquid separation, the filter press has become indispensable in the wastewater treatment sector.

Choosing the right machine is crucial for achieving high dewatering efficiency and environmental compliance. This article analyzes why the automatic chamber filter press is the industry standard for electroplating applications.

Key Characteristics of Electroplating Wastewater

1. Complex Chemical Composition

Electroplating wastewater contains heavy metal ions (Cr, Ni, Cu, Zn), cyanides, and various organic additives. While the total sludge volume might be lower than municipal waste, the separation difficulty is higher.

2. Corrosive Nature

The presence of acids, alkalis, and salts requires machine with superior chemical resistance.

3. Requirement for High Dryness

Post-filtration sludge cakes often undergo stabilization, solidification, or resource recovery, necessitating a low moisture content.

Why the Automatic Chamber Filter Press is the Primary Choice

1. High Filtration Efficiency

Modern automation chamber filter presses feature plate sizes up to 2000mm and filtration areas exceeding 1000m².Optimized chamber layouts and high-pressure feeding systems allow for quick cycle times. Designed to handle large volumes of dilute slurry, ensuring continuous production flow.

2. Advanced Automation and Intelligent Control

Efficiency in a modern plant relies on minimizing manual intervention. Advanced PLC systems manage the entire cycle—feeding, filtration, cake discharge, and drip tray operation. Optional filter cloth washing system maintains optimal permeability, extending the lifespan of the media and ensuring consistent performance.

3. Superior Durability and Corrosion Resistance

Given the harsh environment of a plating shop, machine longevity is a major concern. Plates are manufactured from high-strength, reinforced polypropylene (PP), offering excellent resistance to pressure, wear, and chemical corrosion.To combat acidic vapors and splashes, the main frame can be clad in SS304 or SS316 stainless steel. Critical parts like the automatic flip plates (drip trays) can also be constructed from stainless steel to prevent rust and degradation.

Selecting the right filter press requires a balance of wastewater characteristics, treatment scale, and automation needs. For the majority of electroplating enterprises, the Automatic Chamber Filter Press offers the best stability, dewatering performance, and long-term ROI.
