The sedimentation step handles up to 80 million gallons per day (MGD).For years, a perimeter mat of seasonal filamentous algae formed along the basin and around the filter intakes. While growth was persistent rather than explosive, it created downstream challenges, including algae carryover into filters, higher head loss, shortened filter runs, ...
The Problem: In the manufacturing of cardboard boxes, ink is used to print a client’s information on the container. During the change-outs of the printing press, the ink is washed off the printing roller to ready the process for the next client’s container. This washing generates a waste ink high in solids that in order to discharge the box manufacturer has paid excessive discharge ...
To achieve consistent, high-performance treatment from a trickling filter, it is not enough to focus on the trickling filter alone. Trickling filters are biological systems that depend on stable hydraulics, proper loading, and effective solids separation both upstream and downstream. Understanding the complete path from influent to ...
Physical practices are the preferred method for snail control as they manage populations without detrimental effects to the filter biomass. These strategies should be implemented early into the filter life and done on a consistent basis. ...
