The Zero Liquid Discharge Units work on the principle of Vacuum Distillation combined with Vapour Compression technology using a specialized compressor which makes it an energy efficient and economical method to treat and dispose Industrial Process Water, WasteWater and Reject from RO Plants.
Our ZLD Systems which can vary in size depending on the application have clear advantages over other traditional methods of treatment such as Heat Pump Evaporators and other Zero Liquid Discharge Units.
The high distillate quality allows Zero Liquid Discharge (ZLD) to reduce Fresh Water or WasteWater Discharge costs. Our Zero Liquid Discharge Units consume about 15% less Energy than other similar ZLD products and do not need any Additional Chemicals or other Consumables.
Key Benefits:
- Patented Technology
- Low Cost of Operation
- Low Cost of Waste Disposal
- Automatic Operation
- Minimal Maintenance Cost
- Water Obtained after Treatment can be re-used for the IWWTP Process
The systems are equipped with IoT system (Internet of Things) which enables remote monitoring and predictive maintenance and thereby reducing costly plant downtime.
Brief Benefits Comparison of our ZLD / VC Technology v Conventional ZLD
| Parameter | EnviroTech VC / ZLD | Conventional ZLD |
| Energy Requirement | Electricity Only | Electricity and Steam |
| Source of Energy | Electricity Only | Boiler Fuel and Electricity |
| Components of ZLD System | Bespoke | 1. Boiler 2. Cooling Tower 3. Evaporator |
| Space Requirement | Single Unit
Multiple Sizes |
Space is Required for 3 Components and Piping between them |
| Water Requirement | No Additional Water Requirement | Additional Water is required to generate Steam which is used to Evaporate |
| Compressed Air Requirement | Required for Control Purposes | Not required |
| Ease of Installation | Less Set Up Requirements and Time | Typically takes a week to Set-Up |
