    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
    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.

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.
