Featured Project: Zero Liquid Discharge (ZLD) System for Industrial Gas Production Plant in Thai Nguyen, Vietnam

As industries become increasingly focused on environmental protection and compliance with national regulations, Zero Liquid Discharge (ZLD) systems are emerging as an essential trend in hazardous industrial wastewater treatment. Below is a featured project that highlights our expertise in designing, manufacturing, and operating complex wastewater treatment systems for high-pollution industries.

1. Project Overview

• Project name: Design, manufacture, supply, installation, and operation of a Zero Liquid Discharge (ZLD) wastewater treatment system

• Location: Thai Nguyen Province, Vietnam

• System capacity: 20 m³/day

• Scope of treatment: Hazardous industrial wastewater from an industrial gas production plant

• Objective: Ensure treated water complies with QCVN 40:2011/BTNMT – Column A standards

2. Influent Characteristics

• Facility type: Grade III technical infrastructure

• Wastewater type: Hazardous industrial wastewater with TDS levels up to 50,000 ppm

• Complexity: High contamination concentration requiring advanced treatment technology, especially for handling toxic leachate

3. Applied Treatment Technology

To effectively treat highly polluted hazardous wastewater, this project employed Evaporation Technology – one of the most advanced and effective methods currently used in Zero Liquid Discharge (ZLD) systems.

Key advantages:

• Maximizes recovery of clean water

• Completely eliminates liquid discharge to the environment

• Ideal for industries with complex wastewater containing high Total Dissolved Solids (TDS)

4. Treatment Results

• Clean water recovered: ~18 m³/day

• Output water quality: Meets Column A – QCVN 40:2011/BTNMT standards

Benefits:

• Reduces environmental pollution

• Fully compliant with environmental regulations

• Enables water reuse and lowers long-term operational costs
