500LPH SS304 Drinking Water RO System Two-Stage Reverse Osmosis Plant

There are three main types of failure phenomena in drinking water RO system:

decrease in water permeability, increase in salt permeability (decreased desalination rate), and increase in pressure drop. However, there are many reasons for these failures. Try to find the problem from these failure phenomena. In order to implement the countermeasures such as maintenance and maintenance as soon as possible.

Technical specifications of reverse osmosis water treatment equipment:

Drinking water RO system workflow:

raw water - raw water tank - raw water booster pump - quartz sand filter - activated carbon filter - scale inhibitor dosing equipment - precision filter - first-stage high pressure pump - first-stage reverse osmosis Host - intermediate water tank - secondary high pressure pump - secondary reverse osmosis host - disinfection system - production water.

Advantages of RO reverse osmosis membrane:

1. Cross-flow operation process, strong anti-pollution ability, good regeneration performance and long service life.

2. The separation precision is high, and the permeated liquid is clear and transparent, which greatly reduces the load of the subsequent refining process.

3. Achieve high multiple concentration of fermentation broth and improve product yield.

4. While improving the product yield, the bacteria in the fermentation broth can be recovered, bringing more profit points and environmental protection benefits to the enterprise.

5. There is no need for filter aids in the treatment process, and there is no retention of active ingredients in the fermentation broth.

6. Realize clean production, reduce the amount of acid, alkali and water washing, and greatly improve the biodegradability of wastewater.

7. There is no phase change during system operation, low energy consumption and lower production cost

FAQ:

1, What are the inlet water quality requirements for ro water treatment system membrane components?

2. What is the material of ro water treatment system membrane?

Acetate membrane (CA) : mainly because of its resistance to chlorine, so it is still durable. But its suitable pH range is small, easy hydrolysis

Aromatic polyamide membrane (PA) : water almost can not have chlorine, only through a variety of pretreatment chlorine.

3. RO water treatment system configuration:

First-stage multi-stage process: if the recovery rate is not achieved in the first stage (50-65% in the first stage and 65-75% in the second stage), the multi-stage tandem filtration can be used. The effective cross-sectional area of each segment decreases. 2:2 and 2:3 and 4:2:1

Multi-stage process: when the first stage process cannot meet the effluent quality requirements (the first stage is generally ≤20μs/cm), the product water of the first stage process is sent to another reverse osmosis unit.

The arrangement of membrane components can be divided into series and parallel.
