In June 2011, Evoqua was contacted by a manufacturer of battery equipment for electric lift trucks. The systems are routinely used at many large food processing facilities in Texas. The plant was experiencing difficulty in meeting wastewater discharge requirements of heavy metals, specifically copper, molybdenum and zinc. The facility faced fines and the potential suspension of their discharge permit to the city municipal waste water treatment facility. The suspension would have resulted in additional off-site disposal costs.
