Sequencing Batch Reactor (SBR) is an advancement in wastewater treatment that allows several steps of the process to take place in a single chamber called a ‘reactor’. Since sequencing batch technology is demand-responsive, it resolves the problem of sludge bulking that happens in conventional extended aeration systems, which cause system failure, especially in small units. Advancements in computers coupled with the dropping price of...

The main benefits of Sequencing Batch Reactors (SBR) are: Demand Response Aeration – energy efficiency Smart Controls – for reliable treatment over time No Chemicals or Fixed Media – fewer problems Retrofitable – can repair failing systems SBRs were developed to address the very common problem of sludge bulking in extended aeration systems. Sludge bulking is a leading cause of failure in systems that do not have the...

Nitrogen reduction in wastewater is a two-step process that requires an aerobic step followed by an anaerobic step. Since the aeration step comes first, this makes the process more complicated, since the primary settling portion of treatment plants is anaerobic. If left alone in wastewater, nitrogen causes the following problems: Depletion of oxygen in the water. Causes algae blooms and eutrophication. Pollutes drinking water and can cause blue...

Sludge bulking describes a common type of failure in extended aeration systems where the flocs fail to properly settle out during the settling portion of treatment. This is often the result of the presence of too much or too little oxygen in the wastewater during treatment, leading to the formation of filamentous flocs that do not properly settle. Under proper operating conditions, bacteria form tight flocs with very little filamentation...
Read MoreWastewater treatment seems complicated, and it can be…but at it’s core, it is really quite simple. There are only three basic ways that wastewater is treated: Anaerobic – bacteria consume pollutants in the absence of oxygen. Aerobic – bacteria consume pollutants with powered by oxygen. Filtration – suspended solids over a certain size are physically separated from water. Anaerobic Treatment Anaerobic...
