Electrochemical Wastewater Treatment Equipment: Designed for Treating Desizing

Product Specification

Electrochemical Wastewater Treatment Equipment: Designed for Treating Desizing Printing and Dyeing Wastewater

Quick Details

Desizing and dyeing wastewater, characterized by high concentrations of organic matter (primarily from sizing agents such as polyvinyl alcohol (PVA), starch, and acrylic acid), high COD, high chroma, and poor biodegradability, has become a universally recognized treatment challenge in the textile industry. Traditional treatment processes often fail to effectively decompose macromolecular substances like PVA, and are plagued by systemic issues including massive chemical reagent consumption, large sludge production, high operational costs, and inconsistent treatment performance.

To address the treatment bottlenecks of desizing and dyeing wastewater, we have launched our Electrochemical Wastewater Treatment Equipment. Adopting high-efficiency electrochemical catalytic oxidation technology, this system is specially optimized for breaking down the molecular structures of refractory organics such as PVA, providing a clean and stable treatment solution that eliminates reliance on excessive chemical additives and avoids the generation of secondary solid waste.

Core Advantages of the Equipment

Targeted Degradation of Refractory Sizing Agents to Improve Biodegradability

Through electrochemical reactions, the equipment generates highly reactive hydroxyl radicals, which can effectively attack and cleave the long-chain structures of macromolecular polymers like PVA, degrading them into small-molecule organics and significantly improving the wastewater’s biodegradability (B/C ratio). The entire treatment process requires no addition of chemical agents such as flocculants or oxidants, fundamentally eliminating the production of chemical sludge and the potential negative impacts of reagent residues on subsequent processes.

Integrated Skid-Mounted Design for Flexible Production Layouts

Employing factory-prefabricated skid-mounted modules, the equipment features a compact structure with minimal footprint. It can be fully and rapidly transported to production sites for quick installation and commissioning, making it particularly suitable for printing and dyeing enterprises with limited workshop space and compact layouts, and satisfying their demands for flexible deployment and rapid capacity expansion.

Flexible Multi-Functional Configuration to Precisely Match Treatment Targets

According to enterprises’ actual wastewater discharge characteristics and discharge or reuse requirements, the equipment can be flexibly configured for various applications:

As a High-Efficiency Core Pretreatment Unit: It powerfully decomposes sizing agents such as PVA, drastically reduces COD loads, and creates a stable, high-efficiency operating environment for subsequent biological treatment systems.

As an Advanced Treatment Guarantee Unit: It performs advanced oxidation on the effluent from biochemical processes, ensuring that key indicators such as COD and chroma consistently meet strict water quality standards to satisfy direct discharge or high-standard reuse requirements.

As a Standalone Treatment System: For high-concentration desizing wastewater or small-batch production wastewater, it can operate independently to achieve one-stop treatment from influent to direct compliance with discharge standards.

Intelligent Control, Stable Operation & On-Demand Startup

Equipped with an intelligent control unit, the equipment can adapt to fluctuations in water quality and volume to realize fully automated operation. It features rapid startup capability, flexibly matching the intermittent, multi-batch wastewater discharge characteristics of printing and dyeing production, and truly achieving convenient on-demand operation. The chemical-free design significantly reduces the complexity of daily operations and long-term costs.

Our electrochemical wastewater treatment equipment provides an innovative, high-efficiency, cost-effective, clean, and easily deployable solution for the textile printing and dyeing industry to treat desizing wastewater. It serves as a reliable technological choice to help enterprises achieve stable discharge compliance, reduce comprehensive operational costs, improve environmental management standards, and drive green and sustainable development.
