When starting up a wastewater plant, the biological seed used can influence future treatment efficiency and operational challenges. Domestic activated sludge or digester sludge seeding has potential to introduce unwanted biological and solid contaminants that can...
FOG formation, accumulation and consequences FOG, fats, oils and grease create a variety of problems in sewer collection piping, lift stations and wastewater treatment plants. The most benign result of FOG maybe increased treatment cost at the wastewater plant. Figure...
Small municipal and industrial wastewater systems may find a lagoon system, in conjunction with a mechanical plant or as the only treatment, a cost-effective means of treating the waste stream. This paper addresses applications where a lagoon is the only means of...
Download White Paper Here Even with BNR, denitrification can be challenging when the plants are underloaded for flow as well as biological or biochemical oxygen demand (BOD) and perhaps chemical oxygen demand (COD). Denitrification is inhibited by a lack of available...
Treatment plant managers and operators know the challenges of developing and maintaining the correct population and balance of organisms for optimizing the biological wastewater treatment process. It’s a daily challenge to maintain the right balance of organisms and...
An effective activated sludge system has the capacity to remove ammonia from influent wastewater via nitrification. Several factors impacting efficient ammonia and nitrite oxidation in wastewater treatment include, temperature, and abundance of carbonaceous and...
