Industrial Wastewater Treatment
Clean water. Compliant discharge. Lower operating costs.
Turnkey Effluent Treatment Plants (ETPs) engineered for electroplating and surface treatment wastewater — from design to commissioning, in compliance with UAE regulations.
What We Treat
EVESS® ETPs are purpose-built for the high-toxicity wastewater generated by electroplating and surface treatment operations. We eliminate all major hazardous contaminant classes:
Heavy Metals
- — Chromium (Cr)
- — Nickel (Ni)
- — Copper (Cu)
- — Zinc (Zn)
- — Cadmium (Cd)
Chemical Contaminants
- — Cyanides
- — Acids
- — Alkalis
- — Other toxic substances
- — Organic contaminants
What We Deliver
Permit Compliance
Treated effluent meets UAE Department of Energy Schedule A limits for all regulated parameters.
Reuse-Ready Water
Closed-loop water return to production processes — reducing freshwater consumption and discharge volume.
Lower Lifecycle Cost
Minimal reagent consumption, lower sludge volumes, and automated operation cut ongoing operational expenses.
Reliable Sludge Management
Dewatered sludge cake produced for controlled, documented disposal by licensed waste handlers.

| Cyanide (free) | 0.2 | mg/L |
EGC Technology — Our Advantage
EVESS® proprietary Electro-Generated Coagulant (EGC) technology enables single-stream treatment of mixed electroplating wastewater — eliminating the need to segregate chromium, cyanide, acid, and alkaline waste streams before treatment. This simplifies plant design, reduces footprint, and lowers operational complexity.
Key EGC Advantages
- ✓ Meets strict UAE regulatory limits without stream segregation
- ✓ Enables water return to production loops (closed-loop capable)
- ✓ Produces lower-toxicity sludge — potential non-hazardous classification
- ✓ Handles wide contaminant spectra including organics and dyes
- ✓ No extra salinity added to treated water
- ✓ Lower chemical reagent consumption than conventional methods
EGC vs Conventional Reagent Method
| Parameter | EVESS EGC Method | Conventional Reagent Method |
|---|---|---|
| Stream segregation required | No — single stream | Yes — chromium, cyanide, acid/alkali treated separately |
| Chromium reduction | Electrochemical (no reagents) | Reagent-based (sodium bisulfite) |
| Cyanide destruction | Electrochemical oxidation | Chlorination (hazardous reagent) |
| Heavy metal removal | Coagulation & flocculation | Precipitation (caustic/lime) |
| Sludge toxicity | Lower — potential non-hazardous | Higher — hazardous classification |
| Water salinity increase | None | Yes — from added salts |
| Water reuse potential | High — closed-loop capable | Limited |
| Operator complexity | Lower — automated | Higher — multiple reagent streams |
| Chemical reagent consumption | Minimal | Significant |
| UAE DOE Schedule A compliance | Yes | Yes (with correct sizing) |
