general. The sequencing batch reactor process ( SBR) involves a single complete mix type reactor in which aeration takes place followed by clarification, whence the designation "sequential".Sludge settles when aeration is shut down and a drainage mechanism used to draw off the supernatant liquor.
Sequencing batch reactors (SBR) or sequential batch reactors are a type of activated sludge process for the treatment of wastewater.SBR reactors treat wastewater such as sewage or output from anaerobic digesters or mechanical biological treatment facilities in batches. Oxygen is bubbled through the mixture of wastewater and activated sludge to reduce the organic matter (measured as .

A variety of reactor types including sequencing batch reactor (SBR), upflow anaerobic sludge blanket (UASB), continuous stirred tank reactor (CSTR), and membrane bioreactor (MBR) have been tested for ANAMMOX startup and all show advantages and disadvantages. Usually 20 days matured sludges are better for the reactor start up.
The sequencing batch reactor (SBR) process is a sequential suspended growth (activated sludge) process in which all major steps occur in the same tank in sequential order (figure 1). There are two major classifications of SBRs: the intermittent flow (IF) or "true batch reactor," which employs all the steps in figure 1, and the continuous flow .

A sequencing batch reactor biofilm (MSBR) system was modified from the conventional sequencing batch reactor (SBR) system by installing 2.7 m2 surface area of plastic media on the bottom of the reactor to increase the system efficiency and bio-sludge quality by increasing the bio-sludge in the system.
Activated Sludge: In general, activated sludge plants encompass a variety of mechanisms and processes that use dissolved oxygen to promote the growth of biological floe that substantially removes organic material. The process traps particulate material and can, under ideal conditions, convert ammonia to nitrite and nitrate and ultimately to .

The key components typically removed during the activated sludge treatment process are solids, organic carbon compounds, nitrogen and phosphorus. Figure 1. Diagram of (a) a conventional activated sludge system; (b) a modified Ludzack–Ettinger system; (c) an oxidation ditch; and (d) a sequencing batch reactor system.
Activated Sludge has become the most extensively employed secondary unit process for the treatment of wastewater. Arden & Lockett's original i nvestigations in 1913 involved aerating sewage for several weeks before the treated liquor was permitted to settle & the supernatant water was decanted. Thus, the very original activated sludge process was operated as a batch reactor & became .

This well proven technology can reduce the sludge yield of an activated sludge system between 45 and depending on the point of application and the dosage applied. Additional benefits of ozonation of recirculated activated sludge include improved settleability and denitrification. A dosage range of 0.03 to 0.05 gO 3 /g TSS is suggested .

Advantages for the aerated lagoon / activated sludge system, as compared to an SBR, include: 1) less capital expenditure, as the treatment system is probably already in place to handle final effluent from the mill, and. 2) simpler operation as the condensate stream is treated with other waste streams. 2.2.3 Sequencing batch reactor The SBR .

An SBR is a large tank that contains piping for the injection of air, feedstock (the hydrolysate), and inorganic nutrients; a manifold for the withdrawal of settled sludge; a floating intake on an articulated arm, which is used to withdraw clear supernatant liquid; and a circulating pump to agitate the contents of the reactor.
