Chlorides in Fresh Water

For drinking water, DEM has set a maximum contaminant level of 250 ppm chloride, which is the point at which water starts to taste salty. Some research suggests that, with certain exceptions, fish are less sensitive to chloride exposure than small, free-floating planktonic crustaceans (Evans …

Jul 16, 2009 · Standard value of P alkalinity in Boiler Water is between 50-300mg CaCO3/l. Effects. Higher value of P alkalinity leads to scale formation and overheating of the inside of the boiler causing internal damage. 6. Chloride ion. It causes generation of scale formation. The more the chloride ions, the more the scale formation.

Mar 04, 2019 · the boiler should get good fuel efficiency, and, based on both makeup and treatment dissolved solids, the total boiler water dissolved solids should not go so high that carryover, scaling and corrosion are a potential problem. Chlorides may be maintained in the 60-200 range. The chloride concentration is controlled by boiler blowdown.

WATER TREATMENT TESTING Chloride HP Test Kit

For high-pressure boiler systems, Drew Marine recom-mends testing boiler water chloride levels once a day per boiler. The maximum accepted level of chloride in the boiler water is 16 ppm. This test can also be used to detect low levels of chloride in makeup water. THIS TEST IS NOT RECOMMENDED FOR USE ON TREATED COOLING WATER.

Boiler Water Treatment Guidelines; Columbia Boiler Co

The ratio of chlorides in the boiler water to that of the feed water can be used as a means to determine the amount of blowdown required. The chloride test is unsuitable for feedwater with low incoming concentrations and the concentrations in the feedwater must be averaged over time for accuracy.

May 02, 2000 · boiler water chloride level should be monitored to ensure the blow down rate is correct. If the chloride level is higher than the recommended maximum, more blow down is needed. If it is low, excess blow down is occurring, resulting in wasted chemicals, water, and heat energy. In some cases the chloride level never approaches the recommended
