Electrochemical wastewater treatment equipment is used for the reuse of process

Product Specification

Product Overview

This equipment is specifically designed for the removal and reuse of organic matter in industrial process water. In many production processes, process water (such as cleaning water, cooling water, process water, and overflow from tanks) accumulates small amounts of organic matter, surfactants, or other soluble pollutants. Although the salinity and suspended solids are not high, the organic matter concentration is insufficient for reuse, leading to waste if directly discharged. Conventional activated carbon or resin adsorption methods are inefficient due to frequent replacement and high operating costs.

This system employs electrochemical oxidation technology to efficiently degrade residual organic matter in water without adding any chemical agents, reducing COD, color, and toxicity, ensuring the treated water meets process reuse standards. The equipment boasts significant advantages such as non-scaling and non-clogging electrodes, no secondary pollution, and low operating costs. It can be safely and stably reused in cleaning, cooling, and batching processes, significantly reducing fresh water intake and wastewater discharge..

Working principle

Process water enters the electrochemical treatment equipment after passing through a pre-filter (optional, depending on suspended solids). Under the action of electrodes:

Electro-oxidation: Strong oxidizing groups (hydroxyl radicals, OH, etc.) are generated at the anode, oxidizing and decomposing organic matter in the water into CO₂ and H₂O, or converting it into harmless small molecules, resulting in a significant decrease in COD.

No chemicals, no residue: The treatment process does not introduce any chemicals, resulting in pure effluent that does not affect the original salinity and conductivity of the process water, avoiding adverse effects on production.

The treated effluent can be reused in processes with limits on organic pollutants after simple sedimentation or filtration (depending on requirements)..

Core advantages

Technical parameters (customizable)

Applicable process water reuse scenarios

Parts cleaning water reuse: Removes accumulated degreaser, cutting fluid residue, and surfactants from the cleaning process, allowing the cleaning water to be recycled and reducing the frequency of cleaning fluid replacement.

Cooling circulating water bypass treatment: Removes microbial metabolic products and trace amounts of organic matter from cooling water, preventing biofouling of heat exchangers and increasing the concentration ratio.

Equipment flushing water reuse: Purifies low-concentration organic wastewater from equipment flushing and reuses it for the next batch of flushing.

Production line overflow or rinsing water reuse: Such as rinsing water from electroplating, PCB, and semiconductor industries, returning it to the rinsing tank after removing trace amounts of organic matter.

Wet dust removal wastewater reuse: Removes organic matter and odors from flue gas scrubbing water for recycling.

General industrial process water purification: Any organically polluted water bodies that are not intended to be discharged and wish to be recycled.

Process Flow

Process water (containing organic matter) → Pre-filtration (optional) → Electrochemical treatment equipment → Reuse to production line

This equipment can be connected to the existing circulating water system as a bypass treatment unit to gradually reduce the concentration of organic matter in the system; it can also be used as a single-pass treatment unit to purify the process water after single-use and reuse it..
