A landfill had an existing single basin SBR plant to process the leachate which is notable for its high nitrogen load. The original system was installed with a fine pore diffuser aeration system and due to the chemical/biological composition of the mixed liquor it was prone to diffuser fouling and premature membrane failure.
Since 1977, Endress+Hauser has produced over two million electromagnetic flowmeters. That is more than any other manufacturer. “This magic number stands for high-quality measuring technology and, above all, satisfied customers in all kinds of industries,” says Bernd-Josef Schäfer, Managing Director of Endress+Hauser Flowtec AG, the center of competence for flow measuring technology.
In December 2006, Integrity Municipal Services (IMS) was contacted by the City of California City Plant Manager Greg Fielding to perform an inspection of their RJ-2000® emergency chlorine vapor scrubber system.
The Region of Peel is the second-largest Canadian municipality after the city of Toronto, and draws its drinking water from Lake Ontario — the smallest of the five Great Lakes. To meet the projected population increase from 1,160,000 people currently to an estimated 1,571,000 people in 2031, the Region decided to upgrade and expand its water treatment plant. To deal with seasonal taste and odor compounds produced by algae blooms in Lake Ontario, the membrane plant will be equipped with a Trojan UV-Oxidation system.
Despite the destruction of Hurricane Harvey in August 2017, Duperon® wastewater screening systems in the cities of Cuero and Refugio, Texas – approximately 150 miles southwest of Houston – were virtually unaffected by the storm. Duperon’s FlexRake® bar screens, installed at both locations as well as dozens of other sites in and around Houston, remove objects like rags, paper, plastics, and metals to prevent damage and clogging of downstream treatment equipment. Both communities found essentially no damage to their wastewater screening equipment.
Even though it is a small island, Puerto Rico has historically had big issues with sewage treatment. Due to its tropical location in the Caribbean, heavy storms can create unusually large peak flows at the treatment plants.
The city of Black River Falls in Wisconsin used chemical treatment with ferric chloride (FeCl3) to achieve their effluent total phosphorus (TP) permit of 1.0 mg/l. Historically, the chemical dosing rate was manually adjusted on a daily basis based on the measured effluent TP concentration. The plant was upgraded with an OSCAR process performance optimizer control system with phosphorus controller, which uses continuous measurement of orthophosphate.

The Gainesville Renewable Energy Center is a nominal 100 MW wood-fired biomass power generation facility located in Gainesville, FL. The plant provides about 30% of Gainesville Regional Utilities’ power, reducing the area’s dependence on energy from fossil fuels and greenhouse gas emissions. The client contacted QUA to install their Q-SEP® UF membranes as pretreatment for the plant’s water treatment system.
A WWTP sought solutions to improve process control, as high centrate solids caused plant inefficiencies such as high wasting rates, inefficient capacity and loading, and stress on centrifuges. Read the full case study to learn how the RTC-SD solution controlled polymer dosing in real time, allowing the WWTP to improve solids capture and increase throughput.
