BIOLOGICAL

AEROBIC

Biological Treatment processes where microbes operate in the presence of AIR / O2.
Activated Sludge Process :
It is a process for treating sewage and industrial wastewaters (effluents) using air and a biological floc composed of microorganisms.

In activated sludge process wastewater containing organic matter is aerated in an aeration tank in presence of microbial suspension.

A part of the settled biomass, described as activated sludge is returned to the aeration tank and the remaining forms waste or excess sludge.
Moving Bed Bio Reactor :
Moving Bed Bio Reactor (MBBR) employs thousands of poly-ethylene bio film carriers operating in mixed motion within an aerated wastewater treatment tank. Each individual bio carrier increases productivity through providing protected surface area to support the growth of bacteria within its cells. It is this high-density population of bacteria that achieves high-rate biodegradation within the system, while also offering process reliability and ease of operation.

Benefits :
Sequential Batch Reactor :
Sequencing batch reactors (SBR) or sequential batch reactors are industrial processing tanks 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 wastewater to reduce biochemical oxygen demand (BOD) and chemical oxygen demand (COD) which makes the effluent suitable for discharge to surface waters or for use on land.
Membrane Based Reactor :
The Membrane Bio Reactor is a technology in the field of biological treatment providing treated wastewater for recycling in smaller footprint and under stringent discharge norms.

Membrane being the absolute physical barriers ensures complete removal of suspended impurities.

[ MBR applications include even retrofits of existing systems as well as installation of new systems, for both meeting the most stringent discharge norms and reuse. ]

ANAEROBIC

Biological Treatment processes where microbes operate in the absence of AIR/O2.
Upflow Anaerobic Sludge Blanket Reactor :
UASBR uses an anaerobic process by forming a blanket of granular sludge which suspends in the tank. Wastewater flows upwards through the blanket and is processed (degraded) by the anaerobic microorganisms. The upward flow combined with the settling action of gravity suspends the blanket with the aid of flocculants. Normally referred to as UASB reactor is a form of anaerobic digester that is used in the treatment of wastewater.
