As global environmental regulations tighten, industrial parks are under increasing pressure to minimize their water footprint. In China, industrial wastewater treatment has shifted from mere compliance to resource recovery. Here is how advanced Zero Liquid Discharge (ZLD) technologies are creating a circular economy for water.

Take the Chang’an Electroplating Park in Dongguan as a benchmark. By implementing a combined “pretreatment + advanced treatment” process, this park successfully increased its water reuse rate from less than 10% to over 60%, saving 540,000 cubic meters of freshwater annually. But the real innovation lies in “waste-to-wealth.” Through high-precision separation and enrichment, heavy metals like chromium and zinc are extracted from the sludge and converted into industrial products (e.g., chromium green, zinc oxide), generating a new revenue stream while cutting hazardous waste volume by 40% .

Aerospace Kaitian applies similar logic to complex scenarios. For rural municipal projects, such as the Xielingang Township plant in Yiyang City (Hunan Province), we deployed MABR (Membrane Aerated Biofilm Reactor) smart-packaged solutions. Unlike conventional systems, MABR technology increases treatment efficiency by 50% while consuming less energy, effortlessly achieving Class 1A discharge standards even with fluctuating influent quality.

The future of water management is not just about cleaning; it’s about resource recovery. Aerospace Kaitian focuses on turning wastewater into a resource for industrial parks, ensuring sustainable development for our clients while protecting natural water systems.
