What is Sewage?
Sewage is a mixture of domestic andindustrial wastes containing 99% water, but the remainder contains some ions,suspended solids, toxic chemicals and harmful bacteria that must be removedbefore releasing of water into the sea.
Sewage contains organic impurities such asBOD, COD which cause bad smell and contains harmful gases. If it is not treatedproperly than it will lead to many irreversible problems for human & otherliving things.
Weadopt today technology developments that allow us to realize the vision andoffer advanced wastewater treatment process. Different technologies arementioned below:
ActivatedSludge Process (ASP)
IntegratedFixed Film Activated Sludge (IFAS)/ Moving Bed Bio-Reactor (MBBR)
Sequential Batch Reactor (SBR)
Upflow Anaerobic Sludge Blanket (UASB)
ActivatedSludge Process (ASP)
ASP is most commonly used suspended growthaerobic process. In this process, organic matter present in the wastewater isaerated so that micro-organisms metabolize the soluble and suspended organicmatter. Part of the organic matter is synthesized and form new cells and partis oxidized into CO2 and water to derive energy.
The new cellsformed are removed in the settling tanks and part of this settled biomass isreturned to the aeration tank while the remaining is removed as excess sludge.
Integrated Fixed Film Activated Sludge(IFAS)/ Moving Bed Bio-Reactor (MBBR)
MBBRtechnology works on the principle of attached growth system and uses rotatingbio media to retain an active biomass to reduce the influent BOD Levels.
MBBR configuration combines biofilm and activatedsludge systems for retrofitting existing plants for biological (TN) and totalphosphorus (TP) removal.
It tends to increasing plant capacity and improvingeffluent quality.
Provides BOD removal with a very shorthydraulic retention time (HRT).
FineBubble diffuses are used with the MBBR media in suspension (specific gravity< water) giving a good air dispersal and low level of blockage due to growthof biological film.
Elimination of plugging.
Design and implementation efficiencies ensure lower capital andoperation costs than conventional alternatives.
Simple media addition allows for easy plant expansion toaccommodate population growth or other needs for capacity.
SequentialBatch Reactor (SBR)
The SBR processes save more than 60%of the cost required for conventional activated sludge process in operatingcost and also achieve high effluent quality in a very short cycle.
SequencingBatch Reactor (SBR) is an activated sludge process designed to operate undernon-steady state conditions.
The sequential batch reactor (SBR) process isa fill and draw type activated sludge process where individual reactors arefilled one by one in five discrete periods i.e. Fill, React, Settle, Decant andIdle/ Waste Sludge.
Better resistance to sludge bulkingthan other types of activated sludge systems.
No need of external clarifiers.
Can retrofit existing tanks, basinsand ponds.
Greater ability to meet effluentlimitations (organic and nutrient) than other types of activated sludge wastes/Wastewater treatment systems
