The reverse osmosis system uses a reverse osmosis membrane (RO membrane) as the separation element, and uses tap water, reclaimed water or groundwater as the water source to separate the ions in the water from the water, thereby obtaining deionized water or ultrapure water. The commonly used process is: multi-media filter + activated carbon filter + ultrafiltration membrane + security filter + reverse osmosis membrane module. When the reverse osmosis module is working, most of the ions cannot pass through the RO membrane. These ions will be concentrated on the concentrated water side and finally discharged with the concentrated water; on the concentrated water side, due to the high concentration of water, the RO membrane may Scaling or biological fouling occurs, which eventually leads to clogging of the flow path for efficient operation, or the quality of the permeate water is degraded due to concentration polarization.
The reverse osmosis system uses the reverse osmosis membrane (RO membrane) as the separation element, and uses tap water and reclaimed water to solve the problems that may occur during the operation of the reverse osmosis process. Weliya has developed a series of medicines for different parts of the reverse osmosis process. The protection and control of the reverse osmosis process agent are as follows:
Features of Weliya reverse osmosis agent:
Wide Range
It can provide the whole process of drugs from pretreatment to reverse osmosis, covering pretreatment flocculants, slime control agents, reducing agents, RO scale inhibitors to RO cleaning agents, etc.
Environmentally Friendly
According to customer needs, we can provide phosphorus and phosphorus-free scale inhibitors, oxidative and non-oxygen bactericides, acid and alkaline cleaning chemicals, organic and inorganic chemicals. These pharmaceuticals can meet various requirements for water discharge in different plants.
Excellent Technology
In view of the high SDI of reverse osmosis influent water and frequent sludge fouling and other special situations, BP series drugs and FR series drugs have been developed. BP series drugs can be combined with neutral polysaccharides and humic acid in water, thereby improving the reaction effect of PAC and reducing SDI in RO influent. The FR series of medicines have extremely high permeability, which can penetrate into the bottom of the slime and inactivate the bacteria, thus avoiding the deposition of slime in the system, and ensuring the water flow and the quality of the water produced.
Weliya is able to solve the following problems:
Fouling
Biological pollution
Decrease in water quality
