The Ypsilanti Community Utilities Authority (YCUA) employs a total of 30 mixers in its aeration tanks as part of an anoxic nutrient removal process, and the mixers were failing. The mixers were old, inefficient, and starting to fail, so YCUA elected to replace them with Flygt 4320 mixers. Read the full case study to learn how the potential energy savings for YCUA could easily approach $1 million over a decade.
Call it what you want, but a busted pipe spells nothing but T-R-O-U-B-L-E.
More than 6,800 cubic yards of structural concrete are being used in the construction of a new Trickling Filter and Trickling Filter Pump Station in Bismarck, North Dakota. These structures are being built well below the area’s water table, and the more than 6,800 cubic yards of concrete will protect them against the effects of Mother Nature.
In Iowa, where agriculture is a critical component of the state’s economy, rain is good for crops, but too much rain is not good for anyone. In 2008 the Des Moines Metropolitan Wastewater Reclamation Authority (WRA) retained consulting engineer HDR to provide planning, permitting, design, construction, and start-up services for a high-rate CSO treatment facility called the Combined Sewer Solids Separation Facility or CSSSF.
The hassles of pump ragging lead a South Carolina Public Service District to change out problematic pumps for Flygt N3171 submersibles.
Located on the Belgium-Netherlands’ border, the Lanaye Locks link the Albert and Juliana Canals, the latter of which is a side canal of the River Meuse. The three locks are a vital route between Northern and Southern Europe and have operated alongside each other since 1964 but, as two of these are too narrow to accommodate even smaller convoy, the larger lock had over time become a serious bottle neck for canal traffic.
In late March 2016, an estimated 60-foot wide by 35-foot deep sinkhole developed in Tarpon Springs, Florida, leading to the evacuation of several homes. The sinkhole engulfed part of a nearby road and damaged two sewer lines and a water line.
Sims Bayou begins near Missouri City, TX, and meanders northeast until it reaches Buffalo Bayou.
When California’s Sonoma County Water Agency (SCWA) wanted to improve its sludge solids dewatering as part of a major sludge handling upgrade, they were seeking an alternative to outdated sludge belt press/conveyor technology.
During the cold winter, the Quebec region enters a deep freeze, with temperatures often reaching -25 degrees Celsius.
The sprawling Blue Plains Wastewater Treatment Facility is the largest advanced wastewater treatment plant in the world, with a capacity to treat an average of 370 million gallons of sewage a day.
A utilities department was experiencing frequent unscheduled maintenance visits and corresponding unbudgeted repair bills for the pumps at the township’s main pump station.
Mueller Co. recently announced a new H-306HP fabricated steel tapping sleeve. Designed for hot tapping ductile iron pipe and thick-wall C900 plastic pipe, the H-306HP is made from A36 fabricated steel and meets the requirements of AWWA C223. It features an integral bolt flange, Rilsan nylon coating, working pressures up to 300psi, and is available sizes from 4”-16”. The H-306HP is an economical tapping sleeve ideally suited for use with Mueller® CL-12, C1-36, and Mega-Lite drilling machines in less corrosive soil environments.
The new S&L STAR ONE™ Non-Clog Pump raises the bar on pump efficiency —anywhere from 3-5 percent higher than previous S&L pumps — paving the way for significant energy cost savings.
The Pneumatic Dynamic Lifter is a very responsive compact wastewater relief valve that can handle high pressures and uses a compressed air cylinder to hold the valve closed. This chamber is fitted with a relief pilot that is normally closed as long as the line pressure is lower than the set point. If pressure rises above the set point, the relief pilot opens, causing the air in the cylinder to vent, which in turn opens the valve. The valve closes drip tight when pressure falls below the set point.
The Electric Actuators Type EA25, EA45, EA120 and EA250 offer several beneficial features and covers a wide torque range. With the variety of available options, this family of actuators is ideal for nearly all applications.
The Signet 4150 Turbidimeter provides accurate and reliable EPA-compliant water quality monitoring for municipal and industrial applications.
The Signet 4632 Chlorine Dioxide Analyzer System is an integrated all-in-one system designed to measure Chlorine dioxide residual up to 2 ppm/mg/l.
ecoFIT PE100 Industrial Polyethylene ushers in a new generation piping system designed specifically for broad-based applications. The dynamic combination of specifiable pipe, fittings, valves, and advanced fusion technologies integrates well into the industrial process industry.
This vinyl double containment piping system is fast and easy to install, and is available with a complete selection of pipe, fittings, and valves. Additionally, an innovative "valve-in-valve" design is offered which allows full containment pressure rating. Double-See™ is available in PVC and CPVC; either material may be primary or secondary (PVC x PVC, CPVC x PVC, CPVC x CPVC) with Clear PVC always being an option for the containment pipe. System size options range from 1/2" x 2" to 6" x 10", meeting virtually any application requirement. Installation versatility allows simultaneous joining throughout a system or in combination with patented closure couplings which enable practical compliance with the ASME B31.3 requirement for visual inspection of all primary joint connections during the pressure test before closing the secondary piping joint.
There are lots of applications in the water and wastewater industry that need backflow prevention. Stormwater drainage systems are a perfect example. As Mike Duer, Chief Engineer with Red Valve Company explains in this Water Online Radio interview, “water will backflow through the drainage pipe at high tide, come up through the inlets and cause flooding.”
Realizing energy savings with blowers is a big deal in the wastewater industry right now as utilities try to reign in their energy costs. As Paul Nelson, North American Sales Manager for Egger Turo Pumps points out, the next focus area is going to be energy savings with pumps and valves.
Neil Meredith, Midwest regional manager with Kinetrol USA, talks to Water Online Radio about pneumatic vane actuators – specifically, what sets the good ones apart.
Singer Valve manufactures automatic control valves for municipal water systems — everything from pressure reducing, pressure relief, anywhere where you’d need to control the water running through the line.
Pump station design is the key to great performance and cost efficient constructions. Our experts explain their view on design and how they work to create the best value for customers by reducing footprint and investment costs.
Brian LaBelle, Director of Business Development for GF Piping Systems, provides Kevin Westerling with a tour of the Company’s WEFTEC.16 booth. Some of the new products on display include a dual channel transmitter, a series of electric actuators, a lug-style butterfly valve and a double containment piping system.
Compared to mechanical joint, which uses up to eight bolts on each end, the ALPHA joint uses only one top-mounted stainless steel bolt. This makes the valve with ALPHA ends easier to install, which saves time and money.
