Ephrata Borough Authority WRRF, located in the MidAtlantic region of the United States, has been battling chronic sludge settling issues since undergoing a BNR upgrade in 2011 to meet new permit limits. During the winter months, SVI values have reached as high as 300 mL/g.
Santa Margarita Water District (SMWD), located in southern California’s Orange County, between Los Angeles and San Diego, provides drinking water and wastewater services to over 165,000 residents and businesses. SMWD approached UGSI Solutions about a Polyblend® Polymer Activation System trial at their 3 A Water Reclamation Plant.
The engineers at a municipal wastewater treatment utility were expanding their biogas digester system and were seeking an improvement over their existing, maintenance-intensive flow metering technology. They needed to measure the amount of gas contained within a gas bag as well as the flow rate of the gases traveling from the gas bag system into a co-generation power system.
Traditional municipal wastewater treatment plants typically rely on conventional tests such as Total Suspended Solids (TSS) and possibly Volatile Suspended Solids (VSS) to attempt to quantify biomass.
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 newterra WWT-12 is a stand-alone treatment plant capable of treating all sewage for remote camps with populations of up to 50 people. The self-contained system is housed in a single ISO-certified 40' high cube shipping container and built to endure extreme weather.
Environmental protection, consistent product quality, process optimization and safety – just a few reasons why liquid analysis is becoming increasingly essential. Liquids such as water, beverages, dairy products, chemicals and pharmaceuticals have to be analyzed day in and day out. We support you in fulfilling all these measuring tasks with application know-how and cutting-edge technologies. Discover our comprehensive portfolio and choose the product best suited to your process needs.
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.
World Water Works inDENSE™ system increases process throughput and performance through the selection of dense sludge aggregates with improved settling rates and the promotion of enhanced biological phosphorus removal (EBPR).
Parkson Corporation is pleased to announce the release of the latest video in the Parkson University series, “Sludge Thickening – How Our Industry Has Been Calculating Polymer Usage Wrong.” In this video, we discuss how to correctly calculate polymer use during the sludge thickening process in wastewater treatment.
The video provides a different perspective on the sludge thickening process and explains how various features combine to make the ThickTech the best option for low polymer usage and the highest capture rates of 98% or more.
At Fluence, we have more than 30 years of experience in the design, construction, and operation of waste-to-energy plants for a wide range of industrial and municipal clients. Our proprietary anaerobic treatment technologies process wastewater and sludge to produce biogas, which can be used to produce electricity and thermal energy, or which can be purified to produce biomethane for injection into the grid.
In this video, we discuss the curious science that is the inclined plate settler (also known as a Lamella). The process is a bit counter-intuitive, but through an interesting experiment, this video shows how they work. Inclined plate settlers can reduce required footprint by 80% compared to traditional gravity settling.
