Biological augmentation is the addition of archaea or bacterial cultures required to speed up the rate of degradation of a contaminant. Organisms that originate from contaminated areas may already be able to break down waste, but perhaps inefficiently and slowly. Wikipedia

How Avantu Products ‘Pitking’, ‘Fatking’ & ‘LooKing’ work in the Septic Tank: –

• the products are a combination of specially selected bacteria designed to breakdown
  sewage. The product has a high concentration of bacteria i.e. one billion bacteria per gram.
  So by applying these bacteria to a tank that is overloaded or congested they will rapidly
  convert the solids to water and carbon dioxide due to the large amounts of nutrients
  available to them.
• due to the bacteria in the product being aerobic, anaerobic, and facultative anaerobic they
  adapt quickly to their environment and thrive in the tank and soakaway.
• through applying a shock dose of bacteria, the schedule allows for maximum conversion
  of food to energy and reproduction, the population of bacteria in optimum conditions will
  reproduce as frequently as every twenty minutes.
• the solids and fats in the primary and secondary chambers will be broken down and the
  soakaway will be decongested allowing percolation to continue. The final quality of the
  effluent is improved as the E.coli die off in a healthy environment when they can no
  longer compete for food, the levels of suspended solids, B.O.D. and C.O.D. are lowered,
  therefore Pitking and Fatking will prevent contamination of the ground water.
• once the anaerobic sludge begins to biodegrade, the malodorous odour will disappear. This
  can be expected within the first 72 hours.
