How to determine the dosage of biocides, scale inhibitors, and reducing agents in reverse osmosis systems? What is the basis for this?
I think it depends on the water quality; it’s not good to use too much or too little of the chemical. The chemical manufacturers usually assist you in adjusting the amount
Depending on the water quality, the amount of NACLO added in the preceding system is taken into account to determine the appropriate dosage of the reductant to be used subsequently. An ORP meter is used to ensure that the residual chlorine level does not exceed the specified limit. The dosage of the reverse osmosis sterilant and scale inhibitor is determined based on the recommended amounts for the chemicals chosen.
Fungicides are determined based on the microbial data you test; scale inhibitors are generally chosen depending on the tendency to form scale. However, in most cases, water treatment companies make these decisions purely for business reasons
The values provided by the manufacturer are for reference only, giving you a range to work with. In later operation, it mainly depends on the performance of one’s own equipment as well as the parameters related to the produced water; adjustments should be made flexibly within reasonable limits to find a suitable combination, and no major changes will be necessary for a long time
