Featured Project – High Strength Wastewater Treatment

Recently a highly respected consultant in the water industry issued a wastewater treatment challenge:

Could we treat a high strength dairy waste that was not treatable using conventional Dissolved Air Flotation? A waste that was generated by the cleaning of dairy evaporators and dryers and other process equipment. The waste was very high in COD and TSS – so high it was being hauled to an off-site disposal facility. Everyday. At great expense.

The consultant was risking his reputation and a 20-year relationship with this prominent dairy cooperative to bring in Kemco. This dairy has a knack for “going green” and they wanted to further their sustainability efforts by eliminating or minimizing a persistent waste stream, converting it into a reusable and beneficial condition.

Here’s what happened:
After conducting bench and pilot tests, Kemco designed and built a system to remove the butter fats, milk proteins and other solids using a ceramic microfiltration system (CMF); to follow that, a reverse osmosis (RO) system was built to remove the dissolved contaminants – glucose, lactose, milk salts and detergents.

The full scale system was installed at the dairy in September 2015. The dairy operators were trained to operate and maintain the system, and the results followed.

  • The treated water is good enough to reuse, supplying water to the plant’s belt spray system.
  • The treated water no longer has to be hauled off-site for disposal.
  • Lots of money is being saved!
