WASTEWATER REGULATIONS AND LEGISLATION RESOURCES

• The Water Online Show: Aqua-Aerobic Systems, Inc.

  Granule size separates densified sludge from granular sludge, influencing settling, retrofit requirements, and more. Understanding the difference helps utilities set realistic expectations.

• The Water Online Show: Orege North America

  What running larger belt presses slowly for dryness reveals about capacity, cake solids, and polymer cost, and why a rethink of press design is arriving now.

• The Water Online Show: World Water Works

  Rising costs and tighter limits push wastewater plants toward intensification over expansion. Selective wasting and alternative nitrogen removal pathways can add capacity and cut operating costs.

• The Water Online Show: KROHNE

  Ultrasonic biogas measurement has long struggled with CO2 and its resistance to sound. See how a lower frequency and stronger transducers extend the pipe sizes, moisture levels, and CO2 levels.

• The Water Online Show: AMS

  The rising cost of not treating is reshaping industrial water reuse, pushing facilities toward lower-cost treatment, real-time monitoring, and recovery of valuable materials from waste streams.

• The Water Online Show: Gorman-Rupp Pumps

  Gain insight into single-source lift station supply, from pumps and enclosures to valves and in-house controls, paired with a fast-ship program and domestic casting.

• DTZ Hybrid Sludge Dewatering: Less Space, Less Water, Better Performance

  A compact hybrid dewatering design swaps the gravity belt for a drum, cutting footprint and eliminating continuous wash water while targeting up to 20% better dewatering performance.

• Virginia Beach Shuts The Door On Tidal Flooding

  When heavy rain meets high tide, tidal creeks have no room left to drain. Engineered storage, built from sealed gates and advance pumping, tests a different answer to coastal flooding.

• Rethinking Solids Handling In Wastewater Pumps: Oblique Cone Impeller Geometry

  Fibrous, flushable-laden wastewater has outpaced conventional impeller design. Eliminating exposed leading edges and separating solids alignment from energy transfer offers a clog-resistant path that avoids maceration and preserves efficiency.

• Practical O&M Considerations For PFAS Treatment

  In this session, Andrew Strassner, President of Sentinel Water Solutions, walks through the practical operations and maintenance realities utilities face as they prepare for the EPA’s 4 ppt MCL.
