What are the types of membranes for drinking water ro systems?
1. Cellulose acetate reverse osmosis membrane. Cellulose acetate is also called acetyl cellulose or cellulose acetate. Cellulose acetate is usually obtained from cotton and wood containing cellulose through esterification and hydrolysis, and then processed into reverse osmosis membrane.
2. Composite reverse osmosis membrane. The composite reverse osmosis membrane is mainly composed of the above two materials, consisting of a thin dense layer and porous support layer. The porous support layer, also known as the base membrane, enhances mechanical strength. The dense layer, also called the epidermis, plays a role in desalting, so it is also called the desalting layer. The thickness of seawater desalination layer is generally 50nm, and the thinnest is 30nm.
3. Polyamide reverse osmosis membrane. Polyamides include aliphatic and aromatic polyamides. The main applications in the 1970s were aliphatic polyamides, such as nylon-4, Nylon-6 and Nylon-66 membranes.
Since the pore size of the RO membrane is one millionth of the hair (0.0001 micron), it is generally invisible to the naked eye, and bacteria and viruses are 5000 times larger than it. Therefore, only water molecules and some mineral ions can pass through (the ions that pass through) No profit or loss orientation), other impurities and heavy metals are discharged from the waste water pipe.

Reverse osmosis water treatment system has poor filtration effect:
There are many reasons for the poor filtering effect, such as: the selection of filter material variety, filling amount is unreasonable, filter cycle backwash scrubbing time control is unreasonable, will lead to high SDI.
Low removal rate of organic matter
1. Improve the pretreatment process and improve the measures of COD reduction in the system
2. Try to replace other non-oxidizing fungicides for COD removal.
3. Replace or regenerate when the COD adsorption of the filter material of activated carbon filter is full.
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
