Wastewater Case Studies and Whitepapers

  1. Denitrification Technology Helps Wastewater Treatment Plant Meet China's Stringent Class 1A Standards 9/25/2018

    China has implemented more stringent environmental standards in recent years. Local environmental protection departments now require urban wastewater treatment plants to apply strict enforcement measures to meet effluent discharge standards.

  2. $26,000 Of Savings Per Year With Screentec 8/26/2020

    New Jersey's Lower Township Municipal Utilities Authority had a problem. The utilities authority operates a 5 MGD plant, with wastewater inflow arriving through a 48-in pipe routed 23 feet below grade level. Their manual inflow pump screening setup was difficult and hazardous to clean, and its 2.5" screen spacing let entirely too much non-dispersible waste through. Their 3,000 GPM non-clog pumps were constantly clogging, and workers were repeatedly exposed to a hazardous situation.

  7. A Time-Based Alternative To Multi-Stage Biological Nutrient Removal 6/6/2022

    A phase-activated sludge system (PASS) reduces energy consumption by combining the aerobic and anoxic tanks and alternating diffusers between the on and off position based on a preprogrammed schedule.

  8. Supporting Healthcare With Reliable Solutions - The NextStep Advantage 1/15/2026

    In critical healthcare environments, water sanitation is non-negotiable. When a hospital’s chlorine dosing system began failing, Pulsafeeder’s NextStep pump was selected to restore reliability and ensure patient safety. This case study outlines the challenges faced, the solution implemented, and the broader implications for healthcare facilities nationwide.

  9. Sustainability: It's More Than A Buzzword; It's A Way Of Doing Business 8/12/2021

    For water treatment decision-makers already sensitive to issues involving water scarcity, energy consumption, and environmental stewardship, the concept of sustainability is more than just a buzzword. It is becoming a means of survival in response to changing climate impacts, high energy costs, public scrutiny, and limited financial resources. Here is how better awareness, focus, and execution can make sustainability a reality.

  10. Bridging The Gap: Equitable Investment In City Greenspace 9/27/2022

    Every year, an estimated 10 trillion gallons of untreated stormwater runoff containing raw sewage, fertilizer, oil, pesticides, bacteria and other pollutants enter U.S. streams, rivers and oceans from city sewer systems, polluting the environment and drinking water supplies. In many urban and suburban areas, this runoff also causes significant flooding.
