  • Wastewater lagoons – a new aeration concept

    The use of wastewater treatment lagoons, or stabilization ponds, is a common practice for rural municipalities and industrial facilities. Through the years there have been numerous designs for these ‘sludge settling basins,’ ranging from facultative, partial aerated, and fully aerated systems. But the primary reason for these systems is to utilize relatively shallow earthen ponds, or ...

  • Eliminating sludge islands in your wastewater lagoon

    Old municipal and industrial wastewater lagoons have the tendency to build islands of sludge at various locations around the lagoon. It is most common for older lagoons to build such islands wherever wastewater enters the lagoons. Of course, this is because the solids entering the lagoon have enough weight to fall out of the water as flow velocity is reduced, so the solids pile up just after ...

  • Aeration boosts USA’s largest lagoon system

    The city reports, 'The entire aeration system has surpassed all our expectations.' Problem In 1989, a growing population prompted this northwestern USA community to expand the efficiency and capacity of its wastewater treatment facility. The original unaerated lagoon system had been built in 1967 and had worked adequately for many years. But, the system needed additional treatment ...

  • Feasibility of a flow-through treatment regime by the EOH2O™ electrolytic oxidation process to meet BOD, TSS and ammonia discharge limits from municipal facultative wastewater lagoons

    The patented EOH2O electrolytic oxidation process has been employed as a continuous batch treatment system for reduction of nutrients, TSS, odor, and pathogens in manure lagoons for several years. Due to the positive results of such applications, several Pacific Coast rural municipalities approached Aquatic Technologies to determine if a constant flow-through treatment system could be designed to ...

  • Get more for less: cost-effective solutions for lagoon conversions

    As federal and state regulatory agencies continue enforcing more stringent nutrient removal policies and increasing the plant capacity of wastewater systems becomes essential, the cost of maintaining a productive wastewater system skyrockets. While pricey, meeting the new goals set by the municipalities and industries is an unavoidable necessity. But, there is an alternative to starting from ...

  • Full scale municipal implementations of the Agar IFAS process for municipal wastewater treatment

    Wastewater treatment plant retrofits worldwide are motivated by two main developments: a. Changes in effluent quality regulations, either to more stringent BOD/TSS requirements, or to include nutrient (N and P) removal b. Increase in flows to existing plants, due to either population growth or to expansion of sewerage systems One process capable of giving a cost-effective solution for these two ...

  • Recycling municipal sludge with portable dredges

    Policing the pit. With today's emphasis on resource recovery, even burdensome and seemingly worthless materials are becoming increasingly valuable. Take municipal sludge, for example. For sewage treatment facilities wrestling with the problem of sludge disposal, Liquid Waste Technology may have the answer. The New Richmond, Wisconsin, USA company manufactures dredges and lagoon pumping equipment ...

  • Crossville, TN, municipal drinking water

    The Situation: The City of Crossville, Tennessee, needed to address increasingly strict regulations on the use of gas chlorine to disinfect their community’s water. The Solution: By switching from gas chlorine to MIOX mixed oxidants, the City has reduced operational costs, improved residual durability, reduced byproduct formation, produced longer filter ...

  • Municipal waste water treatment plant case study

    A municipal WWTP in the North of England was experiencing significant problems with accumulations of FOG in the Wetwell at the head of the treatment plant. The FOG would form a solid cap over the well several feet thick. This put considerable strain on the pumping gear, interrupted the performance of the float switches and required regular manual intervention from the staff. High costs were also ...
