Wastewater Case Studies and Whitepapers

  1. Improve Sludge Quality With Sludge Screening 6/7/2021

    Plants with Anaerobic Digestion see phenomenal performance improvements in this process when they removed rags, plastics, and inorganic solids from their digester with the Hydro-Sludge Screen from Hydro International. Learn about a few of the many wastewater treatment plants that have benefitted from cleaner sludge. Read this brochure for brief case studies of how plants have improved their overall operations as well as protected valuable process performance and capacity with the Hydro-Sludge Screen.

  2. City Of Havre, Montana Successfully Utilizes Mechanical Tank Mixing To Prevent Ice Formation And Improve Water Quality 7/17/2018

    Located in north-central Montana, the City of Havre is located in a geography that sees summer temperatures over 100°F (38°C) and winter temperatures that can plunge as low as -40°F (-40°C) accompanied by sustained arctic winds of over 20 mph. These dramatic swings in temperature can wreak havoc on disinfectant levels in the summer by creating a “stratified” tank environment conducive to pathogen growth and allow for ice formation in the tank during the winter. Ice formation can lead to tank coating and appurtenance damage as large chunks of ice can suddenly drop from a higher tank elevation and create catastrophic tank damage. The City of Havre realized that adding simple mechanical mixing to their newly refurbished 3.5 MG West Water Tank would solve both the potential summer water quality and winter asset protection issues.

  3. High Recovery Reverse Osmosis Water Treatment For Industrial, Agricultural, And Municipal Applications 8/13/2014

    Industry accounts for nearly 60 percent of fresh water withdrawals in the developed world and agriculture consumes 70 percent of fresh water supplies globally, according to UNESCO.

  4. Spotlight On Reclaimed Water Regulations: California 3/13/2024

    Technological advancements play a crucial role in shaping reclaimed water regulations, as new methods for treating and reusing wastewater emerge.

  5. Mobile Home Park Installs Modular MBR System To Save Valuable Space 5/18/2020

    Bay Meadows is a year-round RV and mobile home park located along the shores of Lake Ontario. The facility had been reliant on subsurface treatment, however current regulatory requirements eliminated the option of continuing with that approach. In addition to high bedrock, the lack of available area due to design flow values meant a more sophisticated sewage treatment solution would be necessary.

  6. Bowling Green Municipal Utilities (BGMU) Uses One Of The Country's Largest SBR Systems To Meet Current And Future Permit Limits And Environmental Goals 5/5/2017

    Bowling Green Municipal Utilities (BGMU) provides commercial water and wastewater treatment and electrical power services to a population of more than 60,000 in the community of Bowling Green, KY. In 2010, the BGMU wastewater treatment plant was approaching the end of its useful life, just as the utility’s operating permit was up for renewal.

  7. The Tip Of The Fatberg: How FOG Affects Our Sewer System 9/19/2024

    Fats, oils, and grease, commonly referred to as FOG, are one of the most prevalent contributors to sanitary sewer blockages and overflows. In this blog, we will explore the impact of FOG and what can be done to control it.

  8. Case Study: Warm Springs Replaces RBC System With True Batch AquaSBR® Technology To Meet Effluent Requirements In Limited land Space 1/10/2008

    Warm Springs Wastewater Treatment Plant (WWTP) was incorporated in 1950 and utilized a RBC system with secondary clarification and chlorine disinfection to meet BOD and TSS treatment objectives

  9. VigorOx® WWT II Wastewater Disinfection Technology And Viruses 8/1/2015

    VigorOx® WWT II is an equilibrium peracetic acid solution that contains 15% peracetic acid (PAA) by weight at full concentration. The solution exists as an equilibrium of PAA, hydrogen peroxide, acetic acid and water.

  10. Waste Lagoon Rehabilitation A New Look At An Old Problem 9/19/2011

    Throughout the last half-century the municipal and industrial wastewater treatment industry has depended heavily upon the use of waste lagoons in order to provide relatively clean water that could be returned to the environment. These are often called stabilization lagoons.
