West Deptford Energy Station

The Client's Needs

The West Deptford Energy Station (WDES), a natural gas-fired, combined-cycle electric generating facility, generates about 738 megawatts of electricity — estimated to power more than 700,000 homes in South Jersey and northern Delaware. The facility sits adjacent to the Gloucester County Utilities Authority (GCUA) sewage treatment plant, and uses treated effluent diverted from the GCUA discharge for use in the energy station’s non-contact cooling tower makeup, boiler feed-water and plant service water. 

Veolia was awarded a contract to assist in the supply of water treatment technologies to support West Deptford Energy Station’s environmentally friendly and sustainable energy operation. 

The Solution

Veolia furnished West Deptford Energy with a BIOSTYR® Biological Aerated Filter (BAF) and Hydrotech™ Discfilter system, allowing effluent from a municipal wastewater plant to be reused, with a treatment capacity of 7.35 MGD, in the operation of their new “green” energy station. The BIOSTYR® BAF and Hydrotech™ Discfilter systems provide nitrification and filtration of secondary effluent received from the GCUA prior to use of the reclaimed water within the WDES.

The BIOSTYR® process combines biological treatment and filtration into one compact system removing ammonia and a majority of the wastewater solids. The BIOSTYR® effluent is then gravity fed into the Discfilters, which provide an ideal filtration system for fine solids removal, thus producing much cleaner water needed for use in plant operations. 

The use of recycled water is a win for the environment and for West Deptford Energy, making their power station a model of highly efficient and sustainable energy generation, further cementing their reputation as a leader in developing environmentally friendly energy solutions across North America.
