Blame our fast food diets or restaurants’ negligence for what’s going down the drain. Whatever the cause, fats, oil, and grease (FOG) accumulation has become a pervasive problem for wastewater treatment plant collection systems.
Enhancing process reliability and increasing capacity are common issues facing water municipalities. On the one hand, community demographics are constantly evolving and water municipalities need to accommodate the impact to capacity requirements. At the same time, older systems that support pumping operations are not getting any younger and as control systems age, for example, it can become more time consuming to maintain equipment and more difficult to find replacement parts after systems have been in place for many years.
Just 20 years ago, many professionals did not consider using variable frequency drives (VFDs) in wastewater applications. Frequency converters were relatively expensive, and experience using them with the special conditions and requirements in wastewater was limited.
In late 2015 Reliant Water Technologies introduced the Wet Well Wizard, an aeration tool for the wet wells in collection systems. During 14 months of field testing the patent pending Wizard System, the primary objectives were to eliminate FOG (fat, oil and grease) caps and to reduce H2S, eliminating it if possible.
Murfreesboro, Tennessee, is the fastest growing city in Tennessee, and one of the fastest growing cities in the United States with its population more than doubling since 2000.
A public works director in southern Kalamazoo, MI, recommended the county investigate new generation Flygt brand pumps for five troublesome singlephase stations along their system.
V-Bio Polyethylene Encasement is the latest scientific advancement in corrosion control for ductile iron pipe. Its revolutionary formulation allows for complete confidence on the part of the owner, engineer and municipality that no matter how aggressive the soils, the rugged iron pipe installed will last for generations. This new technology builds on more than 50 years of research and development by the Ductile Iron Pipe Research Association. By Jordan Byrd, AMERICAN Ductile Iron Pipe
A new pipe-repair solution promises to save time and money, while also being sustainable, long-lasting, fully scalable, and safe for workers.
Streamlining utility management and operations yields significant savings.
When the Sanitation Districts of Los Angeles County (LACSD) were formed in the 1920s, the agency embarked on its first major project -- the construction of the backbone trunk sewer of the Joint Outfall System (JOS). Since then, the Sanitation Districts have completed many challenging projects, providing environmentally sound, cost-effective wastewater and solid waste management services to over five million people in Los Angeles County.
Fats, oils, and grease (FOG) deposits present a problem for the wastewater industry as they create sewer lines blockages that lead to overflow. Digester systems can successfully remove these deposits with the latest environmentally friendly technology by breaking them down into microparticulates. This paper offers a technical review of the solutions available for applications such as commercial and residential lift stations, grease traps, and wet wells.
DO2E has designed and patented the "Little John Digester" for complete removal of FOG deposits of FOG deposits and H2S waste water.
