Anaerobic Digestion Facility Upgrades to Handle Unique Waste from Yogurt Producer

Published by Water Environment & Technology magazine.

A dairy was considering moving its Greek yogurt production to a city in Central New York, and the city’s water resource recovery facility (WRRF) required site adaptations to handle the high-strength acid whey that develops as a byproduct of yogurt manufacturing. The WRRF also needed to resolve issues caused by its aging infrastructure.

On a very short timetable, WesTech helped the facility transform its 75-year old digester complex into a facility with a 50-percent greater hydraulic capacity and the ability to treat this unique waste stream in a sustainable way.

Water Environment & Technology magazine spotlighted the Cortland, New York case study in a recent Problem Solvers feature.

Key WesTech equipment was used in the plant upgrade: the DuoSphere™ dual membrane solution for gas storage, ExtremeDuty™ Sludge Mixer for mixing of digester contents, tube-in-tube heat exchangers to preheat the whey before being sent to the digesters, and stainless-steel digester covers that were faster to install and required less welding than carbon steel covers.
