|How does Biorganic cultures work
Biorganic (EM) is continuously dosed in the Equalisation or Bioreactor tank having continuous aeration, having retention time preferably between 6 to 8 hours ( the greater the retention the greater the biodegradation), pH between 5 & 10 and temperature below 55 Deg Celsius. Biorganic – Effective Microorganisms (EM) increases the population of active micro organism and enhances the Biological decomposition. The Biorganic (EM) cultures helps in achieving the desired level of MLVSS. Generally a D.O. Level of 2 ppm is desired for the inherent bacteria to oxidize effectively. However Biorganic (EM) Cultures can work effectively even at lower D.O. Levels. Biorganic (EM) oxidizes the suspended particles into water and gases which otherwise has to be chemically coagulated. The value of the Total Suspended Solids, that is the Organic load gets reduced in the Equalisation or Bioreactor tank, before any chemical coagulation is carried out. Since now there are fewer -ve charged particles for coagulation lesser chemicals are used for coagulation, thereby reducing the consumption of chemicals as well as reducing the generation of 'Sludge' termed as 'Hazardous Waste'.
Under Biological decomposition, first Oxidation of the waste water takes place.
Organic waste + oxygen + bacteria CO1 + H2O + NH3+ energy
Due to release of energy synthesis of new cells takes place
Organic waste + oxygen + bacteria + energy C5H7NO2
Finally when organic matter is used up, cells consume their own tissue to obtain energy. This is called Endogenous Respiration.
