Over the past decade, industrial water quality awareness has increased significantly. Many municipalities and private industrial facilities have upgraded or installed new technologies to meet the demands of their wastewater permits.

Advances in water quality science are constantly improving in order to minimize waste, recycle water, improve product recovery and reuse, and provide control of nutrients and toxics in the environment. AquAeTer’s technical experts are renowned in the industry for their expertise and decades of experience in water and wastewater quality improvement.

Case Studies
3rd Party Review
AquAeTer participated as part of a HydroQual team to evaluate wastewater treatment system options for two fully integrated pulp & paper mills in South America. Wes Eckenfelder and Paul Marotta, both of AquAeTer, participated as technical experts on the team. Wes’s 60+ years of industrial wastewater treatment experience and Paul’s 20+ years of industrial pulp and paper experience added a broad experienced-based skill set to the HydroQual team.
ASB Performance
AquAeTer was retained by this client to evaluate their current wastewater treatment system and identify optimization opportunities in their pulp and paper mill ASB treatment process. AquAeTer staff were led by the legendary technical direction of Dr. Wesley Eckenfelder who was deemed the Godfather of Industrial Wastewater Treatment.
Design Review
AquAeTer was retained by HOVENSA, a joint venture between Amerada Hess and Petroleos de Venezuela, S.A. (PDVSA), to conduct a design review of a proposed new activated sludge facility. HOVENSA operates a world-class merchant refinery in St Croix, USVI. The facility is one of the most modern refineries in the United States and, with crude oil processing capacity of 495,000 barrels per day (BPD), is one of the largest in the world.
Nutrient Removal
AquAeTer was retained by a pulp and paper mill to comply with future effluent limitations for nitrogen discharge. The project initially involved evaluation of the current plant performance data. Our technical staff proceeded with wastewater characterization and the application of the Eckenfelder model on kinetic biological treatment for nitrification/denitrification.
Treatment Upgrades
AquAeTer was asked to review a proposed technical design for a wastewater treatment system upgrade at a pulp and paper mill. The mill’s existing treatment system included a very large facultative lagoon that was overloaded and operating primarily as an anaerobic lagoon. Because the Total Maximum Daily Load (TMDL) had a concentration limit of less than 5 mg/L for BOD5, the client was looking for innovative and sustainable solutions to meeting this stringent effluent limit.
