  • How To Choose A UV System For Water Reuse In Your Facility

    Water reuse is, and will continue to be, one of the biggest considerations for companies all over the world in the battle against water scarcity. By reusing process water, grey water, and wastewater, buildings and facilities will reduce their demand for raw water from surface and groundwater sources and reduce the associated costs of supplying raw water and treating raw water before use. One of the treatment methods for accomplishing this is UV disinfection.

  • America’s Oldest Brewery Improves Bottom Line With A “Solids” Solution

    Yuengling brewery plant in Pottsville, PA, brews four major products – Ale, Lager, Pilsner and Porter – each with a different brewing process. Their wastewater contains mostly sugar and yeast and small quantities of spent grain, which is treated at their onsite wastewater treatment plant, built in 2000. Yuengling had operated the static screens for several years, tolerant of the screens’ performance and the resulting operational inefficiencies, however, decided it was time for change.

  • Self-Sufficient WRRF Completes In-House Grit Removal Upgrade

    Aging, inefficient aerated grit facilities at North Davis Sewer District’s (NDSD) treatment plant headworks not surprisingly caused the typical headaches of poorly performing headworks:  downstream process tanks filled with grit and process equipment wore much faster than it should. And not surprisingly, it became a costly hassle for plant staff with annual basin cleanouts.


In addition to reducing carbon, modern wastewater treatment plants also reduce nitrogen and phosphate. For this purpose, the online measurement of ammonium, nitrate and phosphate parameters is required. Nitrite and total phosphate are also occasionally measured.

Doing hydraulic calculations in a spreadsheet is an error-prone process.

The Reliant Water Technologies SCOUT Hydro Profiling System is the answer to obtaining clear and concise shallow water survey data quickly and inexpensively. By not only providing a visual hydrographic ‘picture’ of everything underwater, in any shallow body of water, the SCOUT also provides the volume of sludge in the water body (as well as the volume of free water). The ‘picture’ provided is color enhanced in order to provide clear, definitive delineation of variable depths of sludge, or debris, and includes multi-point water depth over-lays.
