The fully membrane-based concentration technology achieves a specific energy consumption of only 7–11 kWh/m³, comparable to conventional seawater RO membranes, yet delivers a much higher concentration ratio. It saves over 70% energy compared to traditional evaporation methods.
For a high-salinity wastewater treatment scenario with a daily capacity of 1,000 m³, the evaporation crystallization load can be reduced by 60%–80% after membrane concentration, saving millions of CNY annually in steam and electricity costs. Energy consumption comparison: a triple-effect falling film evaporator consumes 300–350 kg/m³ of steam and 18–20 kWh/m³ of electricity, equivalent to an overall energy consumption of 78–90 kWh/m³, which is 8–11 times higher than the fully membrane-based concentration system.
The standard containerized skid module allows integrated installation and relocation; a single unit can serve multiple wastewater sites. It integrates PLC intelligent control and IP65 protection rating, adapting to extreme working conditions, with online monitoring and real-time alarms, supporting unattended continuous operation.
The system incorporates an online membrane performance monitoring device that enables real-time tracking of each membrane module's permeability, promptly detecting performance decline and performing targeted maintenance, preventing damage to individual membrane modules from affecting overall system operation.
TDS can be directly concentrated from tens of thousands mg/L to over 210,000 mg/L, approaching the saturation concentration of sodium chloride, creating optimal conditions for subsequent crystallization or resource recovery. The concentrate volume reduction is significant, allowing a substantial reduction in the size of evaporation crystallizers.
Full series capacities from 0.5 to 500 m³/h are available, supporting multiple skids in parallel for capacity expansion, meeting multi-level needs from single factories to centralized treatment in industrial parks. Actual parameters are custom-optimized based on feed water quality, TDS concentration, and process route.
Coupled with nanofiltration salt separation technology, sodium chloride, sodium sulfate, etc., can be separated and recovered from wastewater, producing industrial-grade salt by-products for sale, transforming "spending money on wastewater treatment" into "recovering resources for profit", aligning with circular economy and sustainable development concepts.
The fully membrane-based process concentrates high-salinity wastewater to over 210,000 mg/L, significantly reducing the evaporation crystallization load and lowering full-cycle operating costs.
The volume of electroplating concentrate can be reduced by up to approximately 20%, markedly shortening subsequent evaporation steps, lowering energy consumption, and increasing recovery rate.
Combining concentration with nanofiltration salt separation, sodium chloride and sodium sulfate are separated and recovered, producing industrial-grade salt by-products for sale.
Without adding evaporator capacity, the fully membrane-based technology can more than double the treatment capacity of an existing ZLD system, solving production bottleneck pain points.
Rapid response to environmental inspection requirements with on-site deployment completed within 1–7 days. Achieves compliant wastewater treatment while enabling resource recovery.
The concentrated high-salinity brine can be treated via nanofiltration to separate and recover valuable metal ions such as sodium and potassium, facilitating subsequent resource extraction.
