The price of an industrial RO plant can vary depending on a number of factors, including the permeate flow rate, TDS, recovery, type of membrane, and operating hours. Permeate flow rate: is the amount of water that is produced by the RO plant. The higher the permeate flow rate, the more expensive the plant will be. Total dissolved solids (TDS): is the amount of dissolved solids in the water. The higher the TDS, the more difficult it will be to remove the contaminants, and t
