Introduction to fully automatic stainless steel secondary reverse osmosis equipment:

Fully automatic stainless steel grade 2reverse osmosis equipmentIt is a process that relies on reverse osmosis membranes to separate solvents and solutes in a solution under pressure, including colloids, organic impurities, heavy metal ions, bacteria, viruses, heat sources, and other harmful substances, as well as 97% dissolved salts. The system has a desalination rate of up to 96-98%. The method of using first stage reverse osmosis effluent and then entering second stage reverse osmosis purification is adopted to achieve an effluent conductivity of ≤ 3.0 μ s/cm.

Water inlet requirements for fully automatic stainless steel secondary reverse osmosis equipment:

·Water supply temperature: 5~45 ℃

·PH range: Normal operation 3-10

·Water pollution index: SDI<5

·Turbidity:<1.0NTU, preferably controlled between 0.3~0.5NTU

·Total iron: Fe<0.1mg/l (related to dissolved oxygen content in water)

·锰： Mn<0.05mg/l

·Free chlorine:<0.1mg/lhuo cannot be detected

·SiO2 in concentrated water:<150mg/l (25 ℃)

Process flow of fully automatic stainless steel secondary reverse osmosis equipment:

Raw water tank → booster pump → multi-media filter → activated carbon filter → scale inhibition and dosing system → security filter → first stage high-pressure pump → first stage reverse osmosis → intermediate water tank → pH regulating device → second stage high-pressure pump → second stage reverse osmosis → pure water tank.

Control and Performance of Fully Automatic Stainless Steel Secondary Reverse Osmosis Equipment:

1. The core components of the reverse osmosis system are all imported membrane components.

2. Automatic shutdown with no water, low pressure or full water, implementing automatic control, and automatic flushing of RO membrane to reduce pollution rate.

3. The pure water tank automatically produces water in case of water shortage, and the low-pressure switch protects the high-pressure pump from damage due to water supply stoppage. The high-efficiency and low-noise high-pressure pump reduces operating noise and energy consumption.

4. The conductivity meter continuously monitors the quality of the produced water.

5. The inlet and outlet pressure gauges continuously monitor the pressure difference of the reverse osmosis membrane, indicating when it needs to be cleaned. The automatic shut-off valve is used to prevent water from continuing to flow in during shutdown.

6. The entire machine is made of stainless steel 304, which is beautiful and has a long service life.

7. The preprocessing is also controlled by a fully automatic method, without the need for manual backwashing.

8. The recovery rate of secondary reverse osmosis can reach up to 80-90%, and all concentrated water flows back to the primary reverse osmosis system, saving water sources.

Features of fully automatic stainless steel secondary reverse osmosis equipment:

1. The rate of imported accessories is over 90%.

2. The degree of automation in operation is high.

3. Low pressure full water automatic shutdown.

4. High pressure full water automatic shutdown.

5. Waterproof pressure fluctuation protection.

6. The automatic controller regularly flushes the pre filter material.

7. The IC microcomputer controller automatically flushes the reverse osmosis membrane.

8. Automatic water quality monitoring.

9. Small footprint, low energy consumption, and no pollution.

10. The process is simple, the water quality is high, and it is easy to operate and maintain.

11. High removal rate, with dissolved salts exceeding 97%.

12. Organic matter with over 98% colloids, bacteria, and heat sources with over 98%.
