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.
In 1997, back before text messaging and cell phones, Duperon Corporation installed the FlexRake® FP Full Penetration Coarse Bar Screen into its first wastewater treatment plant at the City of Adrian, Michigan. The same equipment is in operation today, with all of its original components, with the exception of a motor/drive head bearing replacement.
Cardston WWTP’s choice of a dewatering system to replace its belt press, Huber Technology Q-Press®, has a striking comparison to the plant’s previous technology in both the footprint and the attention it requires. The Cardston staff also noticed striking improvements in water separation, end-product dryness and offensive odor by-product. Read more about how the Q-Press® helped Cardston become a better neighbor.
The Huber Technology EscaMAX® gives control over what gets in the stream whereas their previous process gave them no way to prevent rag balls from flowing into pumps and mixers and causing slowdowns and clogs.
Efficiency goals met! Life expectancy of expensive variable frequency drives increased! Ragging build-up on selector mixers all but eliminated! Reduction of debris from 25-30 gallons to a few handfuls! Highest possible percentage of inorganics removed from flow! Plant kept in amazingly consistent treatment mode! These are not the dreams of treatment plant supervisors but are actual results produced by EscaMAX® Perforated Screens.
Reduction of ragging is merely one of the benefits the EscaMAX® Perforated Plate Screen bestows upon its implementer. But this is such a huge factor, that mitigating it brings night-and-day results in other areas such as reducing debris in the grit channel, increasing space for energy-producing biosolids in tanks, and releasing cleaner end products.
The Huber Technology Strainpress has helped Napa Sanitation District maximize its investment in the FOG receiving and injection system by improving operations, ensuring the protection of downstream components and enhancing the production of a valuable, revenue generating asset.
Fort Worth Village Creek has gone far beyond managing its scum. The plant has implemented an efficient way to continuously skim the scum out of the channel flow and effectively process it through anaerobic co-digestion so that its resulting methane gas is useable. In short, the liability was turned into an asset.
With a population of about 15,000, Steinbach is the third largest city in Manitoba and one of the fastest growing areas in Canada. The current system has been operating since 1993, an eternity in the world of technology. Because the wastewater department was already familiar with operating the existing Xylem/Flygt M&C SCADA system with Aquaview software and APP controllers, they decided to inquire what new technologies the company could offer. Read the full case study to learn more.
The grit particle is a microscopic menace that still confounds many wastewater treatment plant (WWTP) operators. It is not always easy to recognize how much grit is costing you in equipment wear, maintenance, and energy usage, let alone to know the best way to rid your plant of it.
The West African City of Abidjan in Côte d’Ivoire has historically provided drinking water to its five million residents from water treatment plants that use hydrated lime systems. But because of the high content of carbon dioxide in the local groundwater, up to 160 ppm, setting the water to calcium carbonate equilibrium using hydrated lime was economically, operationally and environmentally challenging for the city of Abidjan.
The Albert R. Davis Water Treatment Plant (WTP) in Austin, Texas, is one of three water treatment plants supplying drinking water to the greater Austin metropolitan area. The plant was built in 1954 and has had multiple upgrades over the years, increasing its capacity to 118 million gallons per day (MGD).
