Boiler Water Treatment Chemicals, Feed, and Control. Feedwater dosage is 8.8 ppm to yield 10 ppm free EDTA and 26 ppm polymer. 4 If the hardness goes up to 1 ppm or the product is used in another system where the hardness is 1 ppm, the feedwater dosage increases to 43 ppm to obtain 10 ppm free EDTA. This would yield a high polymer level of 129 ppm.
