Abstract

This paper intends to provide an overall vision of SBR technology as an alternative method for treating waste water.SBR technology differs in various ways from conventional technologies used in biological treatment of wastewater. The most obvious difference is that in SBR technology, the reactor volume varies with time, whereas it remains constant in the traditional continuous flow system. The advantages of SBR technology include the flexibility of operation (change of phase), feasibility of operation at low retention time, control over microbial population and various reactor configurations. SBR process consists of several time oriented periodic steps, characterized by a series of process phases viz. fill, react, settle, decant and idle, each lasting for a defined period during which wastewater is treated. The success of SBR technology depends on the great potential provided by the possibilities of influencing the microbial system in the reactor. SBR processes are comparatively easy to operate and cost efficient and this process saves more than 60% of the expenses when compared to conventional activated sludge process.
