In spite of the recent abundance of water, many of California’s aquifers continue to balance on the edge of water scarcity. Decades of overpumping have reduced the amount of ground water available to supplement surface water resources diminished by drought. The Pure Water Monterey Ground Water Replenishment Project (Monterey Pure), addressed the need to replenish a local aquifer, by piloting Advanced Water Treatment (AWT) processes, to determine the best method to convert secondary wastewater into a pure water resource.
The Hagerstown Wastewater Treatment Plant in Maryland incorporated several plant modifications, one of which was the conversion of their disinfection process from the use of ozone to UV.
The North Columbus Resource Facility recently completed a $12-million replacement of its settled water filtration, removing the existing Wheeler filters, their three-part media and 10-inch poured concrete underdrains, which were no longer efficient.
Installing and operating an ozone oxidation system for wastewater remediation at a gold mine located in a remote region of Alaska is full of challenges.
North Las Vegas has installed some of the largest rotary fine screens operating in the United States. The center feed drum screens are critical to protecting the membrane bioreactor, enabling the plant to maintain extremely low turbidity coming off their plant that is better than most potable water. Read how they are putting the ROTAMAT RPPS to work.
When Plainfield, IN, needed to double their permitted capacity from 2 MGD to 4 MGD at their South wastewater treatment plant, they faced a dilemma. Like most treatment plants, space is at a premium, and compact design was needed not only for the current expansion, including the addition of a post aeration structure, but to preserve as much room as possible for projected future expansions.
During the summer of 2015 the Waging WWTP in the Bavarian Chiemgau district was desperately looking for an energy-efficient, high-performance sludge thickening plant to replace the centrifuge they had been using. The objective was to optimize digester capacity, gas yield and sludge handling in the overall process on site. Read more about their successful implementation.
The Chiquita WRF plant was looking to improve the performance of their existing gravity thickeners better than the 2.3% DS that they were previously achieving. In their search for a solution they discovered the S-Disc technology from Huber Technology.
BCR Environmental utilizes the Huber Technology S-Disc thickener in their sludge neutralization process. Because the system is both simple and reliable they chose to standardize on the S-Disc. The design of the technology enables the operators easy access to monitor their process. Read how BCR is putting the S-Disc to work.
Previously to installing their new Septage Receiving Station 18-Mile Creek WWTP had very little protection from unknown debris entering their plant from haulers. The plant reports that in the time that the RoFAS Septage Drum and WAP Washpress have been operating, they’ve processed many septage loads without issue.
