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.
The Hudson River, in the Capital District of Albany, NY, is a popular recreational area for boating, swimming and fishing. Unfortunately combined sewer overflows following storm events and snow melt from sewer systems dating back to the 1800’s were causing increased fecal coliform counts which in turn resulted in health alerts and limited access to the river. After considering several alternatives, the Albany County Sewer District selected a Wedeco Duron 60i2-2.5X4, with high power Ecoray 600W lamps, for their disinfection system.
The City of Dundee is a growing community with a strong economy boasting three wineries within the city limits and several others in the surrounding Willamette River Valley. The City’s existing WWTP was nearing capacity, and the limited discharge to the Williamette River would not adequately support Dundee’s planned growth.
The AquaNereda® Aerobic Granular Sludge System (AGS) is an innovative biological wastewater treatment technology that provides advanced treatment using the unique features of aerobic granular biomass. This advanced nutrient removal process can reduce footprint up to 75% and energy up to 50% when compared to conventional activated sludge systems.
The high cost of maintenance and unsatisfactory performance of the aging equipment in the Bonnybrook headworks made it clear that significant changes were in order. The older poorly performing headworks allowed screenings to pass to the downstream process units causing operational and maintenance problems. By installing the Huber RakeMax® and matching WAP washpress, Calgary’s process performance immediately improved.
Havre WWTP was in search of a replacement solution that would improve their screening process. The old system often became plugged with rags. The City learned quickly to depend on Huber’s RakeMax technology to help it overcome its challenges. The highly effective technology enables the City’s operations to remove such a high percentage of inorganics that the downstream processing are more effective and components are less stressed.
It had become obvious to The City of Guelph that it was time to replace several of the components in its treatment process. Project leaders wanted to upgrade its treatment processes by implementing leading edge technology. By thoroughly researching what was available they choose the technology and vendor that was the best match for their long-term wastewater treatment goals of the City.
Facing new limits on acceptable levels of DBPs in the drinking water, as well as age-old complaints about the taste of the water during the summer algal bloom, the North Texas Municipal Water District turned to ozone disinfection as a possible alternative able to address both concerns.
In an effort to reduce reliance on dwindling surface and groundwater supplies in Texas, the Colorado River Municipal Water District (CRMWD) constructed a new Raw Water Production Facility (RWPF) in Big Spring. Big Spring is a 27,000-member community located in West Texas approximately 300 miles west of Dallas. This RWPF treats secondary wastewater to a standard that allows it to be re-introduced directly into the raw water supply for the water treatment plants of Big Spring, Odessa, and other communities in the region.
Read the full case study to learn how the County of Maui Department of Water and IMS determined that spent caustic used at the local wastewater treatment plant and the acid wash solution generated during the cleaning process could be neutralized on-site and disposed through the local wastewater treatment system.
In December 2006, Integrity Municipal Services (IMS) was contacted by the City of California City Plant Manager Greg Fielding to perform an inspection of their RJ-2000® emergency chlorine vapor scrubber system.
The MNI Wiconi Water Treatment Plant in Ft. Pierre, SD was built for the Oglala Sioux Rural Water Supply System between 1997 and 2002 with a grant provided by the U.S. Department of Interior.
