AMINOTREAT - Bacteria for reducing Ammoniacal Nitrogen in effluent
Ammoniacal Nitrogen is one of the most problematic issues faced by the wastewater treatment plants today. While being highly toxic to the environment, ammoniacal nitrogen is also difficult to treat with general bacteria. The levels of ammoniacal nitrogen in industrial waste water is often very high making it necessary to build large sized wastewater treatment facility to achieve higher retention time values. The demand to build a bigger facility is a natural outcome of the slow nitrogen metabolism by common wastewater bacteria in an ETP. High ammonia concentrations in wastewater can be dealt with using specific bacteria that can naturally assimilate nitrogen at a faster rate. Conventional nitrogen removal from water involves a two step process of nitrification and de-nitrification carried out by four different set of bacteria. Conventional ammoniacal nitrogen degradation system requires functioning of all the four different bacterial systems that have different growth requirements. Controlling such process is a very tedious task. Even then, the nitrogen assimilation rate is usually not up to the mark. These conventional systems are delicate and work only in ideal situations, where all parameters are maintained in accurately in a narrow range. Any deviation is likely to put the system out of track. Aminotreat is designed keeping the real life conditions of the waste water treatment plant in mind. Bacteria in Aminotreat do not follow the conventional nitrification and denitrification process. Instead the nitrogen removal is done in a single step. The microbes agglutinate in water to form microflocs that provide ideal niche environment for efficient nitrogen removal. In this microfloc, the anaerobic or anoxic bacteria remain at the core of the floc. While, the aerobic bacteria occupy the peripheral region of a floc. Hence bacteria in Aminotreat align themselves spatially to carry on the ammoniacal reduction effectively. The system is robust and is sturdy to resist toxicity or shift in ETP parameters. The system can tolerate fluctuations in pH and DO. We are aware that many a times high ammoniacal nitrogen levels are also associated with higher concentration of solvents and TDS. Aminotreat is a perfect blend of bacteria for such effluents.
RECALTREAT - Bacteria for reducing Recalcitrant COD and degrading Xenobiotic compounds in wastewater
Today our technological development has enabled us to manufacture several compounds that meet thousands of application requirements of the modern world. Unfortunately many of these compounds are foreign to biological system and are not a part of biological food cycle. As a result generic bacteria are not able to degrade these compounds. Such non-biological compounds are called Xenobiotic compounds. Xenobiotic compounds give rise to recalcitrant COD in effluent. Xenobiotic compounds lead to high COD, but the BOD from these compounds is minimal. If you are having low BOD but at the same time high COD, it is possible that you have xenobiotic or non-natural compounds in the effluent. Generic bacteria are not capable of degrading xenobiotic compounds. We have isolated a range of bacteria for degradation of xenobiotic compounds. These bacteria can degrade several aromatic compounds like benzene, phenols, etc., at high concentration. We have also used these bacteria for degrading polypropylene, dyes, pigments, paints, hydrocarbons, etc. Recaltreat is formulated with a set of bacteria that have a wide range of degradation capabilities. These bacteria produce a range of enzymes that remain stable in harsh environments and facilitate transport of pollutants to bacteria for effective degradation. Generic bacteria do not have the necessary transport mechanisms to adsorb and transport xenobiotic chemicals intracellular. Bacteria in Recaltreat can effectively solubilise and degrade xenobiotic compounds using natural metabolic pathways.
ODOTREAT - Eliminate foul smell from effluent
We sense the odour of a substance when tiny molecules of that substance are dispersed in air and they reach our nose. Volatile substances are easily dispersed in air and are carried to long distances by air. Often may aromatic compounds in wastewater have obnoxious odour. Bad odour or foul smell could also be due to production of H2S in waste water. Anaerobic or anoxic reactions in a wastewater treatment plant may lead to formation of foul smelling gases leading to odour problem. Incomplete bacterial degradation leads to breakage of large molecules into smaller fragments that could be dispersed in environment. Incomplete degradation often leads to foul smell. For example rotting meat, spoilt egg etc. Many times the effluent itself has compounds that give off bad smell. Odotreat has a set of bacteria that are capable of not just complete degradation, but also of assimilation of intermediates. As a result the compounds that lead to bad smell in wastewater are completely digested and converted into bacterial biomass. Odotreat was successfully applied at Taloja Waste water treatment plant and it helped in significant reduction of odour. Ododtreat deal with the issue right at its roots and differs from conventional techniques where the odour is masked. As a result Odotreat reduces the COD levels significantly while eliminating bad odour from the effluent. If you are dealing with anoxic effluent and are looking for bacteria to reduce H2S dour in wastewater, then you must consider
SULPHTREAT- Reduce hydrogen sulphide levels in effluent
Sulphtreat is a bacterial formulation that is designed specifically to remove H2S smell from wastewater by degrading waste in anoxic conditions without producing H2S gas. Sulphtreat - Reduce Hydrogen Sulphide levels in effluent High amount of sulphur in effluent may lead to formation of H2S in anoxic conditions. The effluent becomes evidently black in colour with obnoxious odour around the plant. Air and water naturally have sulphur reducing bacteria. These generic bacteria convert sulphate in water to hydrogen sulphide. Not only does hydrogen sulphide lead to foul odour, it also is toxic to environment. High amount of H2S in air may lead to nausea and headache to staff at ETP and long term exposure may lead to serious health hazards. We have consortia of micro-organisms that can assimilate sulphates into biomass which can be separated in settling tank.
