Background of Needs
European industrial parks are required to comply with the environmental protection regulations on zero wastewater discharge, while recovering production wastewater for circulating cooling and cleaning purposes.
Technical Solution
A closed-loop process integrating pretreatment + MBR (Membrane Bioreactor) + NF (Nanofiltration) + RO (Reverse Osmosis), with the core configurations as follows:
Treats industrial wastewater (with COD ≤ 500 mg/L) to remove organic substances and suspended solids.
Purifies wastewater to meet industrial pure water standards, with a water recovery rate of ≥ 85%.
3.Monitors water quality in real time and interlocks with discharge/recycling valves to ensure compliance with EU environmental protection regulations.
500 Ton/Day Wastewater Recycling Project in a German Chemical Industrial Park
Joint bidding with local European engineering service providers, supplying core membrane equipment and undertaking system integration.
Achieved 100% recycling of wastewater, reduced annual freshwater procurement costs by 1.2 million euros, and obtained the EU Zero-Emission Industrial Park certification.
