 In lower temperatures, a brine solution can be used to de-ice or reduce freezing temperatures on roads.Brine is a byproduct of many industrial processes, such as desalination for human consumption and irrigation, power plant cooling towers, produced water from oil and natural gas extraction, acid mine or acid rock drainage, reverse osmosis reject, chlor-alkali wastewater treatment, pulp and paper mill effluent, and waste streams from food and beverage processing.Along with diluted salts, it can contain residues of pretreatment and cleaning chemicals, their reaction byproducts and heavy metals due to corrosion.
