500L/H double-stage RO+EDI purified water machine project plan

According to the water quality indicators of your company's tap water, this raw water is not suitable to be used directly as your company's production water.Therefore, the raw water must be desalinated.This project recommends selecting an advanced, mature reverse osmosis desalination device with stable effluent quality and stable system operation as the main desalination equipment of the system; the system operation cost is low and it is easy to realize automation.Reverse osmosis water treatment systems are very economical.In order to ensure the long-term reliable and stable operation of the key equipment reverse osmosis device, a pretreatment system must be set up to meet the reverse osmosis membrane (RO) water inlet indicators: turbidity <0.5NTU, SDI<4, and residual chlorine <0.1ppm.According to the raw water quality, the pretreatment system consists of multi-media filters, activated carbon filters, dosing systems and related auxiliary equipment.The process flow of the two-stage reverse osmosis + EDI system is as follows:
