Case Studies

Turn-key program reduced chemical expenses, solids , and energy costs.

A Northeast Acid Mine Drainage (AMD) treatment facility was using calcium hydroxide (lime) to precipitate iron from the mine pool water. The iron in the water stream is in soluble form known as ferrous iron (Fe2). Lime was used to...

A refinery in the Northeast was looking at options to dispose of 10,000 bbls of a high strength, high pH caustic wastewater that had been stored in one of its tanks.  The wastewater had very high phenol levels (14,000 mg/L), which did not allow for processing through the activated sludge...

Project Scope

A Midwest wastewater treatment plant was struggling with problematic hydrogen sulfide (H₂S) levels at two points within their facility arising from biosolids processing. The factors driving the need for H₂S control included worker safety, corrosion of electronics and concrete, implied regulatory limits and biosolids odor control. Along with...

Project Scope

A field demonstration was initiated in February 2014 by the Suffolk County Department of Public Works (SCDPW) to quantify the impacts of Peroxide Regenerated Iron-Technology (PRI-TECH®) as a more economic approach in maintaining biosolids odor control in the solids handling phase at the Bergen Point Wastewater Treatment Plant...

Project Scope

In upstate New York, a wastewater treatment facility historically utilized potassium permanganate to control odors at two locations in their biosolids processing operations. The first location was into the waste activated sludge (WAS) fed to a gravity belt thickener. The second location was into a mixed stream of...

Project Scope

A large stainless steel and titanium pickling and finishing company had an issue with visible NOx fumes discharging out of one of their Midwest facilities. The plant had been tasked with the elimination of the fumes that were being generated from their various pickling baths they utilize. Visible...

Project Scope

A power plant on the West coast was experiencing problems with its large, open-circuit cooling tower system. Excessive bacterial growth in the tower was leading to solids accumulation within the tower’s fill and an increasing frequency of TSS excursions in their blow down discharges to the local municipal...

Two nitrate products producers were looking for a solution to their visual NOx emission plumes during frequent plant start-ups that would satisfy both public and regulatory expectations.

USP Technologies was brought in to design a proprietary technology solution which introduces dilute H2O2 into the NOx absorber during start-ups to reduce...

This specialty chemical manufacturer was experiencing discharge violations (phenols, bio-toxicity) resulting from ineffective treatment with their existing processes and needed to pre-treat a wastewater stream to reduce phenols by 90% prior to mixing with higher flow waste streams.

USP Technologies was tasked to design and provide a Fenton’s Reagent treatment program whereby...
