Rongxuan Environmental Protection has constructed a recycling system covering multiple industries through technological innovation and scenario-based solutions in the field of industrial wastewater resource utilization, and the main practice paths are as follows:

I. Core technology innovation to drive resource transformation

Low-temperature evaporation technology: For chemical industry, electroplating and other difficult wastewater, low-temperature evaporator is adopted to realize concentration and separation of wastewater, with a recovery rate of more than 95%, which significantly reduces the cost of water for enterprises.

Waste acid resourcing process: develop waste acid evaporator to separate heavy metal ions in electroplating wastewater with high efficiency, realize waste acid recycling and heavy metal recovery, and reduce production cost by 30%-50%.

Biological treatment coupling system: combining biochemical process and membrane technology (such as MBR+RO), treating wastewater into “new water” that meets the reuse standard, and improving the reuse rate of water resources.

Scenario-based solutions for key industries

Automotive parts industry: in the degreasing and cleaning wastewater treatment, through the “deep purification + resource” technology chain, to achieve zero wastewater discharge, and recovery of organic solvents and other usable resources, to help customers pass the environmental acceptance.

 Electroplating industry: For heavy metal-containing wastewater, we adopt a quality separation process to recover over 500 tons of copper, nickel and other metals annually, while the recycled water can be used directly in the production line cooling system.

Chemical industry: customized “pretreatment + membrane separation + evaporation and crystallization” full-process solution for chemical enterprises to achieve 100% reuse of wastewater, salt crystallization products can be used as industrial raw materials for secondary sales.
