Double stage reverse osmosis water treatment equipment, also known as double stage reverse osmosis ultra pure water equipment, is a secondary desalination equipment after the reverse osmosis equipment. It consists of a pre-treatment system, a first stage reverse osmosis system, and a second stage reverse osmosis system. Generally, the effluent conductivity is between 1us/cm-5us/cm (the inlet conductivity should be less than or equal to 300us/cm).

Characteristics of dual stage reverse osmosis water treatment equipment:

1: Under the condition of no phase change at room temperature, solutes and water can be separated, which is suitable for the separation and concentration of thermosensitive substances. Compared with separation methods with phase changes, it has lower energy consumption.

2: The reverse osmosis membrane separation technology has a wide range of impurity removal.

3: High desalination rate and water reuse rate can intercept solutes with particle sizes of several nanometers or more.

4: By using low pressure as the membrane separation power, the separation device is simple, easy to operate, maintain, and self control, and the site is safe and hygienic.

Application fields of dual stage reverse osmosis water treatment equipment:

1: Electric power industry: boiler feed water, cooling water;

2: Electronic industry: semiconductor industry ultra pure water pre-treatment, integrated circuit cleaning water, formula water;

3: Food industry: formula water, production water;

4: Pharmaceutical industry: process water, formulation water, washing water, injection water, sterile water preparation;

5: Beverage industry: formula water, production water, washing water;

6: Chemical industry: production water and wastewater treatment;

7: Drinking water engineering: preparation of ultrapure water and purification of drinking water;

8: Petrochemical industry: deep treatment of oilfield injection water and petrochemical wastewater;

9: Desalination of seawater: production and domestic water use in island areas, coastal water scarce areas, ships, seawater oil fields, etc;

10: Environmental protection field: recovery of precious metals and water from electroplating and rinsing water, achieving zero or micro emissions

The dual stage reverse osmosis water treatment equipment adopts a multimedia filter, an activated carbon filter, and a security filter as the primary treatment, effectively removing suspended solids, mud and sand, particles, organic silicon colloids, organic matter, odors, residual chlorine and other impurities in the raw water, so that the water quality after ion exchange treatment meets industrial production requirements. After going through the backend for precision treatment system (mixed bed system), ensure that the produced water quality meets the requirements for production water.

The pre-treatment system usually includes quartz sand filters, activated carbon filters, and softener filtration systems. The main function of pre-treatment is to remove organic matter, suspended solids, colloids, residual chlorine, and calcium and magnesium ions from water, to ensure the inflow requirements, reduce the generation of scale and algae growth, microbial pollution, and oxidants during operation.

Characteristics of dual stage reverse osmosis water treatment equipment:

1: Efficient and energy-saving, due to the combination of reverse osmosis technology and efficient ozone disinfection method, the entire system operates at room temperature and low pressure, with low equipment investment, low operation and maintenance costs, and reliable and energy-saving. The operating cost of membrane treatment method is only 12-15% of that of distillation method, which is very economical and highly competitive.

2: Stable and reliable. Adopting membrane process and multi-media filter for pretreatment; The principle of microporous permeation in reverse osmosis membranes ensures the removal of all larger ions and molecules in water, making it easy to remove volatile organic pollutants with larger molecular diameters.

The water production process of the two-stage reverse osmosis water treatment equipment:

Raw water pump, quartz sand filter, activated carbon filter, precision filter, primary reverse osmosis equipment, secondary reverse osmosis equipment, ultra pure water tank water point.

It has been widely used in electronics, power, electroplating, lighting appliances, laboratories, food, papermaking, daily chemicals, building materials, paint making, batteries, laboratory testing, biology, pharmaceuticals, petroleum, steel, glass cleaning water, semiconductor industry, fine chemicals, optics, pharmaceutical water, dialysis medical water. In other fields.
