We are among the prominent Manufacturers of Sewage Treatment Plant in India whose products are widely accepted in industries. The Sewage Water Treatment Plant is fit for all kinds of biological and chemical treatments.
Treatment Techniques
The basic technology generally used for the treatment of Sewage is activated sludge process. This applies to both small and large processing plants and the difference lies in the arrangement and enhancement of the various sections of the process. The activated sludge process is a natural process and nature offers us a unique solution to treat sewage. Nature has provided a special balance in this process in that the micro organisms present when the food levels are high, will also consume the largest amount. This allows the quick breakdown of the BOD levels to more reasonable levels. Once these levels are reached, other microorganisms, which are heavier and less mobile, will reduce the BOD levels further, until the final acceptable standards are obtained The fact that the last organisms are large and heavy, allows us in practical terms to settle these organisms out very efficiently, producing a clear liquor.
To balance the process, we can identify four major sections in a activated sewage plant system:
Collection and anaerobic storage
Aeration of the Sludge
Setting of the sludge removing all solids
Chlorination and phosphor removal to bring the final effluent up to the required standard
Biological Treatment
Biological treatment is the process of utilizing naturally occurring living organisms to degrade, stabilize and destroy organic contaminants. These microorganisms use the waste as their source of energy and carbon. Biological treatment technologies are restricted to organic wastes, and therefore have limited application. It is appropriate at this point to review some principles of biological process. All living organisms require a source of energy and carbon to be able to develop and reproduce. Many organisms (autographic) get their carbon from inorganic compounds (such as CO2), while other organisms (heterotrophic) use organic compounds to get their carbon. Aerobic and anaerobic metabolic pathways are used by microorganisms to degrade organic waste. During aerobic respiration, the organism utilizes oxygen to break down complex organic compounds into simple in organic salts, carbon dioxide and water. These microorganisms require an electron acceptor (oxygen in the case of aerobic), nutrients such as nitrogen (N) and phosphorous (P), and other trace elements. One of the most important characteristics of the waste is its biodegradability. Microorganisms can either directly use the contaminated waste and gain energy and carbon from it; or, with the help of another substance they can co-metabolically break down the contaminated waste. The biodegradability of a waste can be measured in the laboratory through BOD (5) / COD tests. BOD (biological oxygen demand) is a test through which contaminants can be categorized according to their biodegradability. COD (chemical oxygen demand) is a measure of the oxygen required to oxidize all compounds in water, both organic and inorganic.
Chemical Treatment
The technologies described in this section are chemical treatment technologies that are used for the cleanup of uncontrolled hazardous waste sites. In general, chemical treatments alter the structure of the waste constitutions to render them less hazardous than their original form. The objectives in using chemicals and chemical reaction are to either immobilize, mobilize for extraction, or detoxify the contaminants. A chemical technology may achieve one or all of the above tasks. Before describing any of the treatments in detail, a few points must be emphasized.
The feasibility of chemical treatment is dependent on site and waste characteristics. Therefore, a careful study of site hydrology and geology must be performed before choosing teleology.
Many chemical treatments involve delivery of a fluid to the subsurface. Care must be taken to avoid the migration of treatment reagents since they can be toxic themselves.
Chemical treatment can be applied to both organic and inorganic wastes. However, a detailed study of the waste must be done, so that the wrong reagents are not mixed with the waster resulting in increased toxicity.
Sequential Batch Reactor
The Sequential Batch Reactor combines. The efficiency of activated sludge aeration with batch. Treatment to provide exceptional efficient quality even. Under extreme loadings.
Benefits And Features
Reduces main pollutants including ammonia by 95% Reduces phosphates by 99% Batching system eliminates peak surges Fully recyclable All components easily accessible The SBR uses an aeration process known as activated sludge but operates on a storage and batch treatment cycle Which ensures full treatment of all the effluent â₉€œ even under pack flow conditions. Crucle sewage enters the primary Settlement Tank where gross solids settle out and the supernatant liquor. remaining near the surface can be drawn off. Substantial buffer storage volume is provided to cope with even the most extreme peak flow loadings and aerated by a powerful air bubble diffusers for a period of 4 to 6 hours. During this aeration cycle efficient Oxygen transfer cultures of bacteria (the active sludge) which feeds on the sewage liquor thereby removing most of the organic pollutants. After carnation, the bubble diffuser is switched off and three is a setting period of two hours during which the dense activated sludge sinks to the bottom leaving behind the clarified effluent, which is then discharged in to the drain.
The SBR is an advanced biological aeration type treatment plant designed to produce a very high quality of final effluent in addition to overcoming several of the common problems
Common problems, which normally occur, in other treatment plants are : Peak surges flow (i.e. Mornings and evenings) can force effluent through the
Plant before it has had sufficient treatment time.
Fixed film, types, which have a media matrix, can suffer from media blockage because of excessive bacteria growth. Replacement / maintenance of the media material may be required at regular intervals.
Mechanical / electrical components within the tanks are difficult to maintain and can be a safety risk.
The liquor is not spread evenly over the available bacteria preventing an adequate Oxygen supply.
