Method for removing cations and anions from an engine coolant liquid

摘要: An apparatus and method for removing particulates, hydrcarbons (such as oil), cations anions including nitrite ions from a liquid, such an engine coolant liquid having freezing point depressant situated in internal combination cooling system. The has at least one filter particulates hydrocarbons; strong acid cation exchange bed the hydrogen form cations; base anion hydroxide anions; separator separating gas containing nitrogen, nitric oxide and/or nitrogen dioxide, that is produced bed. hydrocarbons, cations, comprises providing ions; passing through zone filtering wherein hydrocarbons are removed liquid; exchanger converted into dioxide. further subsequently dioxide to produce depressant.
