China Industrial Demineralized Water Equipment Suppliers in China - Factory Direct RO & EDI Solutions Factories, Manufacturers
Product Description
📋 Product Overview and Positioning
The industrial demineralized water equipment manufactured by Shanghai Tongjie Environmental Protection Technology Co., Ltd. adopts a combined process of "Pretreatment + Reverse Osmosis (RO) + Mixed Bed (MB) or Electrodeionization (EDI)" to perform deep demineralization of raw water, producing demineralized water with conductivity below 0.1 μS/cm.
The equipment operates on the principles of ion exchange and membrane separation, without the need for a heat source. The produced water quality meets the low salt content requirements of various industrial applications such as high-pressure boilers, electronics cleaning, and pharmaceutical preparation.
⚙️ Process Flow and Principle
Raw water first passes through the pretreatment unit to remove suspended solids, residual chlorine, and organic matter, then enters the RO unit. The RO membrane removes more than 97% of dissolved salts, colloids, and microorganisms.
Depending on final requirements, the RO permeate enters a deep demineralization unit:
