How to add rubber additives

Although rubber additives have many types, but the added ways are mostly the same, and there are two main ways:
One is the impact of dosing: the general is to reverse osmosis pressure to 0.3Mpa below, the use of drugs should be completed in 2-4 hours. The reason why this will be used, mainly due to the surface of the reverse osmosis membrane is still a small amount of surviving bacteria algae and microbial salt trapped in the membrane surface, these bacteria in a certain period of time will grow and grow, it must be a regular impact , And to remove the algae on the membrane surface. Weekly or two weeks of shock dosing, concentrated kill system in the bacteria algae. The impact of the dosing is generally about 100ppm.
Another is a continuous dosing: the need for daily dosage of the drug should be placed in the dosing tank, diluted with water ten times, even with dosing pump plus. This is because as a reverse osmosis system when the bacteria algae inhibitor, can greatly reduce the growth rate of bacteria on the membrane surface. To prevent the system of bacteria and algae breeding.
The specific dosage of rubber auxiliaries depends on different water quality and working conditions. Dosing should be continuous with the vote plus. Can be the original water bacteria bacteria to a minimum, the general rate of bacteria and algae in more than 99%.
