Headworks BIO wins lagoon nitrification project

Headworks BIO was awarded one of the largest lagoon nitrification projects in the United States at $3.69 million. The company will supply post-lagoon treatment for BOD polishing and nitrification using Moving Bed Biofilm Reactor (MBBR) technology for a wastewater treatment plant expansion in Batesville, Ark. The expansion will increase flow from 4 mgd to 9 mgd and decrease ammonia nitrogen to less than 8 mg/L. MBBR is a fixed-film treatment process that uses virgin polyethylene biofilm carriers to support the growth of biofilm. Oxygen is delivered to the carriers through coarse-bubble aeration.

Honeywell undertakes $35 million renewable energy project in Wilmington

Honeywell announced a $35 million renewable energy project for the City of Wilmington, Del., that includes a first-of-its-kind facility to convert two sources of biogas into power and heat for the city's wastewater treatment plant. The project is part of a citywide initiative to decrease energy costs and greenhouse gas emissions by 35 percent and meet nearly 50 percent of electricity needs with renewable energy. The centerpiece of the new project is a Renewable Energy Biosolids Facility to harness biogas to generate electricity for the Hay Road Wastewater Treatment Plant and provide thermal biosolids drying. The facility uses methane produced by plant digesters and from the nearby Cherry Island Landfill.

The M.C. Dean electrical design-build and systems integration firm teamed with PC Construction to win a contract for upgrades to the Final Dewatering Building at DC Water's Blue Plains Advanced Wastewater Treatment Plant, the world's largest treatment facility of its kind, serving 1.7 million people. The project will renovate and outfit electrical rooms with new medium-voltage switchgear and electrical systems.

Parkson Enhanced Nutrient Removal (ENR) system passes test

Parkson Corp. has successfully demonstrated a complete enhanced nutrient removal (ENR) system, proving its ability to cut costs and meet strict wastewater treatment requirements. The results from the 18-month trial of the DynaSand EcoWash filtration system combined with the Biolac extended aeration activated sludge show that the system performs effectively and at about half the capital cost of other designs. Tests were conducted at the town of Laurel in southwest Delaware.

Kruger wins ACTIFLO contract in Hillsboro, Ore.
