A guidance document for professionals in the food and beverage industry to provide information on anaerobic wastewater treatment and potential downstream polishing.

On July 27 and 28, 2015, the Water Environment Federation convened a meeting of stormwater professionals from across the U.S. The Johnson Foundation at Wingspread cosponsored the meeting, which was held at their conference center in Racine, Wis. These stormwater sector leaders participated in a discussion that captured current trends and conditions in stormwater, as well as opportunities and pathways toward a sustainable and financially sound stormwater sector. This report presents a vision for the future and six overarching objectives that will help achieve this vision. The vision conveyed here is formed not through consensus of the discussion participants, but through their shared input as described by the Water Environment Federation. Each chapter begins with a forward-looking statement describing the ideal future of the stormwater sector. The chapters describe how the current state of stormwater affects these six overarching objectives. Each vision is supported by a series of concrete action items that build toward the overarching objectives and, ultimately, the vision—taking rainfall challenges and creating opportunities for results.

Collection system debris is the material that is removed from the sewer system during pump station wet well cleaning, sewer line cleaning, and blockage removal. It contains personal hygiene items, grease, rags, wipes, sand/gravel (grit), and wastewater. Grit is a special problem. These materials can damage mechanical equipment both in the collection system and at the treatment plant. Accumulated material reduces pipe and tank capacity, clogs piping, and increases wear on pumps and valves, significantly increasing maintenance costs.

Grit includes sand, gravel, cinder, or any other heavy solid inorganic material in wastewater. Removing grit early in the treatment process greatly reduces abrasion and wear on pumps and other equipment. Grit removal also reduces grit accumulation in digesters, aeration basins, pipes, and channels. There are many types of grit removal systems such as vortex grit systems, detritus tanks, horizontal flow grit tanks, and aerated grit tanks. The grit removed from any of these types grit tanks is typically pumped to grit dewatering and cleaning systems. This fact sheet will describe the operation of one type of vortex grit removal system.
