Wholesale High-Salinity Wastewater Reduction System - ZLD Technology by China Suppliers and Factory Suppliers, Supplier
Product Description
Our Solution
Shanghai Tongjie Environmental Protection's high-salt wastewater reduction and resource recovery system employs a combined process of OARO (Optical Advanced Reverse Osmosis) for high-salt concentration, DTRO (Dialysis-Treated Reverse Osmosis) for high-pressure reverse osmosis, and MVR (Membrane Vapor Recovery) for evaporation and crystallization. The raw water has a TDS concentration of 10,000–50,000 ppm, which is concentrated to over 150,000 ppm TDS, achieving zero wastewater discharge and salt resource recovery.
Target Industries: Adapted for high-salt industries such as chemical engineering, electroplating, lithium salts, coal chemical industry, pharmaceuticals, and printing and dyeing.
Core Advantages
High concentration ratio and reduction rate: The combination of pretreatment + OARO reduces the concentrated water volume by 80–90%, significantly decreasing the evaporation scale.
Modular skid-mounted design: Enables rapid factory prefabrication and on-site commissioning within 30 days, reducing civil construction by 60% while allowing phased expansion.
Energy conservation and cost reduction: Energy consumption is reduced by 40%. Membrane concentration replaces partial evaporation, with energy consumption per ton of water ≤ 0.8 kWh, resulting in a 30% reduction in operating costs.
Pollution-resistant and scale-preventing: Long-lasting stable wide-channel anti-pollution membrane + softening pretreatment, tolerant to high hardness/high COD, with cleaning cycle extended by 3 times.
