The waste treatment of metal cleaning compounds varies greatly based upon the type of cleaner being treated and the concentration thereof. In all cases, the spent cleaner solution must be neutralized from highly alkaline or acidic conditions. This process cracks waste oil, grease, and surfactants thereby making them more amenable to wastewater treatment.

Once again the cold months of the heart of winter are upon us.  With the cold weather comes a variety of potential problems for the wastewater treatment process. These include poor floc formation, slow coagulation/agglomeration in neutralization tanks, and reduced settling time in clarifiers.

Wastewater pre-treatment lines and pre-paint lines of traditional zinc, manganese phosphate, and/or iron phosphate will typically have two primary discharge concerns: zinc metal and phosphorus.

If your application is using a cleaning solution, once the solution is ‘spent’ [dirty and consumed], you have choices; ship the solution off site for disposal, slowly bleed this solution into your existing waste treatment flow, or batch treat the spent solution.

Many wastewater solutions require ‘oil separation and removal’ for meeting treatment requirements such as: BOD/COD, suspended solids, oil & grease, metal levels, and turbidity. The WaterCare line offers solutions to may oil treatment applications.
