CE Certification China Suppliers Factory Industrial Demineralized Water Equipment with RO and EDI for High-Quality Purification Factory, Supplier
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 some organic matter, then enters the Reverse Osmosis (RO) unit. The RO membrane is a polyamide composite membrane that, under an operating pressure of 1.0–1.8 MPa, removes more than 97% of dissolved salts, colloids, and microorganisms. The conductivity of the RO permeate is typically reduced to below 50 μS/cm.
Depending on requirements, the RO permeate enters a deep demineralization unit:
🛠️ Equipment Structure and Core Components
Multimedia and activated carbon filters for solids and chlorine removal.
Spiral-wound brackish water membranes with FRP/Stainless steel vessels.
Mixed bed with resin traps or EDI modules with built-in ion exchange.
PLC cabinet for automatic operation, monitoring, and fault alarms.
