Effluent treatment dairy

Waterleau constructed a wastewater pretreatment and renewable energy production plant for a cream cheese manufacturing facility under a design and build contract. High-strength UF permeate, a byproduct from the cheese making process, is treated using a pulsed up flow sand media anaerobic reactor to maximize BOD removal efficiency and energy production potential.

An estimated 200 million BTUs per day of renewable energy offsets the use of natural gas in the customer’s production facility. The anaerobic treatment system also provides an alternative to the costly practice of converting UF permeate to animal feed, and the environmentally sensitive land application approach.

In addition to the biological pretreatment of the high-strength waste stream, process wastewater is pretreated by a Krofta dissolved air flotation to remove TSS, FOG, and phosphorous.

For similar applications, Waterleau now offers an updated reactor configuration from the BIOTIM® family of anaerobic systems.
