The City of Dixon, Illinois, located 100 miles west of Chicago, went on-line with an upgraded 4.5 MGD wastewater treatment plant in February 2002.
Solar dryers are fully automated to feed, move, and discharge biosolids cost-effectively. Even climate changes throughout the year are easily monitored and controlled to produce optimal output. Installation is very flexible with options to add components at a later date. Full automation means employees seldom need to enter the greenhouse and are free to use their time elsewhere.
The City of Tooele, UT was looking to update their Bio-Solids program and move away from a limiting Class B product. They needed to produce a more flexible reusable material. The City found the Huber Technology SOLSTICE® to be the perfect solution and was pleased to discover the technology to be simple to maintain as well as provide a cost-effective operation. Find out how the dryer raised the quality of the bio-product to Class A.
Built in the 1980s, Little Blue Valley Sewer District operates Atherton, which was designed to reduce the primary process chain to preliminary bar screening and aerated grit removal, while relying solely on secondary treatment performed in four, standalone 42-ft by 400-ft aeration/clarification basins. Read the full case study to learn how upgrading the activated sludge process with a combination of Xylem’s Flygt pumps and mixers created a solution for the city’s sewer district.
For years, the wastewater treatment plant in Villa Mercedes, David City, Panama emitted harsh odors and created a rampant mosquito population, a situation the neighboring residents found impossible to deal with. Treatment at the plant needed improvement to successfully treat up to 4.6 million gallons of wastewater per day, eliminate harsh odors and reduce the mosquito population.
A WWTP chooses a new screw press that takes up less than half the space that the old belt press had occupied. This was striking for the operations team but not as striking as the fraction of time they needed to spend managing the screw press.
As interest in biogas grows, more attention is being paid to measuring biogas flow, which has long been a problem area in process measuring technology.
Greer Commission of Public Works (CPW) has been providing water, wastewater and electric services to the City since 1914 with natural gas service added in 1957.
Located between San Francisco and Sacramento in Solano County, California, the Fairfield-Suisun Sewer District (FSSD) services more than 135,000 residential, commercial and industrial customers over 41 square miles.
The 1.5 MGD West Carrollton Wastewater Treatment Plant in West Carrollton, OH came on-line in 1989 and today serves 12,000 area residents. The activated sludge facility produces an average of 200 wet tons/month of sludge that, following belt filter press dewatering, is spread on area farmland by a biosolids management company.
Serving over 200,000 ratepayers, the City of Tacoma operates two award-winning wastewater treatment plants.
The City of Dartmouth, MA, Water Pollution Control Division is responsible for operating the town’s 3 million gallon per day wastewater treatment facility, a testing laboratory, a composting site, a sludge.
Evoqua's OMNIFLO® SBR MAX system with Jet Tech technology combines the benefits of a true-batch SBR with the benefits of a continuous fill batch reactor process to treat wastewater influent flows to over 5 times design. The OMNIFLO SBR MAX system optimizes hydraulic handling during storm flows, reduces equipment sizing and cost, and can trim energy costs over 15%!
The Cyclix™ system is a controls package that can be utilized with a JetMix™ hydraulic mixing system to optimize operational time and reduce energy costs. The system consists of a control panel with a programmable logic controller (PLC) and temperature sensors that monitor temperature within the reactor to dictate when the mixing system should be operated.
Backed by more than 35 years of design and manufacturing experience, MRI’s Packaged Water Treatment Systems combine into a single tank the reliable, all-stainless steel, space-saving components proven through years of use in large municipal treatment systems.
With increasingly stringent regulations and adoption of membrane filtration, the pressure is on for all stages of pretreatment — chemical feed, flocculation, sedimentation, and filtration — to act in concert. In response, Meurer Research, Inc. has developed MRI Flocculation Systems™ — integrating turbine, horizontal, and hydraulic flocculators into multi-stage systems with a self-cleaning hydraulic final stage, maximizing versatility and performance.
Developed in 2002, the MRI Hoseless Cable-Vac Sludge Collector removes settled solids throughout the basin, even from the final 2′ at the end wall typically left un-collected by other sludge collectors.
The Lamella® is the original inclined plate gravity settler. Introduced by Parkson in 1971, it has been the industry standard for this technology.
This revolutionary aerobic wastewater treatment solution is modular and reduces energy usage by up to 90% compared to conventional treatment.
The Reliant Water Technologies SCOUT Hydro Profiling System is the answer to obtaining clear and concise shallow water survey data quickly and inexpensively. By not only providing a visual hydrographic ‘picture’ of everything underwater, in any shallow body of water, the SCOUT also provides the volume of sludge in the water body (as well as the volume of free water). The ‘picture’ provided is color enhanced in order to provide clear, definitive delineation of variable depths of sludge, or debris, and includes multi-point water depth over-lays.
Rapidly produce FREE engineering designs for activated sludge wastewater treatment plants.
Built for both non-technical (basic inputs) and technical (detailed inputs) users, our WWTP Design Generator automatically integrates decisions and calculations from each engineering discipline (process, mechanical, civil, architectural, electrical) to create a preliminary design for a wastewater treatment plant (WWTP).
What used to take several weeks of work involving experts and engineers from multiple disciplines can now be completed within six hours using Water Online’s groundbreaking WWTP Design Generator.

The Aqua Caiman™ represents the next generation of multi-rake mechanical bar screens. In designing the screen, Parkson combined over 40 years of experience working on thousands of in-channel screen installations with in-depth market and engineering research. This allowed us to better understand the weaknesses of existing multi-rake and articulating rake screens.
This video examines the economic evaluations of life cycle cost over capital investment and introduces an innovative new bid procedure to assure the best overall value for the end user.
Dennis Kaeser, Technical Sales Manager Chain and Scraper for Evoqua, provides an overview of some of the replacement chain and scraper products the Company offers with a particular focus on ease-of-replacement and operator safety.
Kevin Westerling interviews Mark Pamperin, a biological processes product manager with Evoqua, about retrofitting and rehab systems for wastewater treatment plants.
