New Septage Receiving Plant Results In Decreased Maintenance
New Septage Receiving Plant Results In Decreased Maintenance

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.

    Safe, Energy Efficient Disinfection For 45 MGD Combined Sewer WWTP Improves Water Quality

    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.

    Plant Operations And Maintenance Staff Benefits From New Headworks

    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.

  • Replaced Screen Brings WWTP From The Stone Age To The Modern Age
    Replaced Screen Brings WWTP From The Stone Age To The Modern Age

    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.

    Indirect Potable Reuse With UV-Oxidation - Big Spring, Texas (Case Study)

    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.

RWL Water Provides Dissolved Air Flotation Technology To The Industrial And Municipal Sectors RWL Water Provides Dissolved Air Flotation Technology To The Industrial And Municipal Sectors

Dissolved Air Flotation (DAF) is a physical/chemical technology designed to treat wastewater containing particles that are slow settling, of neutral density, or buoyant. The DAF works by producing a stream of micro-fine bubbles that attach to solids and lift the solids to the surface where they can be removed by a surface scraping mechanism. This technology is particularly applicable to food and other industries where solids are fluffy, light and slow to settle such as fats, oils and greases. Our systems are designed and customized to handle a wide variety of influent water quality and flow rate. RWL Water provides robust systems that have a small footprint, and are easy to install, operate, service and clean.
