N-FIX Biological Inline Bore Treatment

There are four types of inline sludge deposits associated with bacterial growth:

  • Iron bacteria
  • Manganese deposits
  • Sulphur slime
  • Iron sulphide

Iron bacteria deposits and associated slimes are usually red, yellow or tan in colour. Iron bacteria is filamentous (from bacterial filamentous) as a voluminous and gelatinous mass. The gelatinous can trap fine soil particles so that iron bacteria may contain more than 30% sand. In addition, old iron bacteria can become crystallized and hard. Iron bacteria have caused problems in water supplies since the dawn of time and there are many references in history to undrinkable red water that is covered in slime and also to plugged wells.

Manganese has been a serious problem in Australia in form of bacterially enhanced gelatinous black deposit. High salt sodium (Na) in ground water.

Sulphur slime is a yellow to white stringy deposit formed by oxidation of the hydrogen sulphide that may be present in ground water. Soluble sulphides are oxidized to elemental sulphur, predominately by bacteria Thiothrix niuea and Beggiatoa species. So that globules of elemental sulphur are deposited within the filaments of the bacteria. The fluffy masses of slime are held together by intertwining of the long filaments of the bacteria and sulphur slime containing hydrogen sulphide.

Iron sulphide is a gelatinous black precipitate formed from the reaction between ferrous iron and hydrogen sulphide. It can become a clogging agent when present in amounts that can block soil pores.

N-Fix Inline Bore Treatment Solves Inline Deposit Problems:

  • Raises and stabilises alkalinity of water by encouraging autotrophic bacteria and causing rapid oxidisation: under more alkaline conditions, ferrous (iron) and manganous (manganese) ions tend to oxidise rapidly;
  • Optimises pump capacity and reduces the need for heavy duty maintenance;
  • Is a natural biological formulation which eliminates the use of acid based products that cause corrosion and potentially contaminate ground water;
  • Eliminates blocked pumps, drains, pipes, filters, sprinklers and irrigation lines;
  • Improves flow rate of pumps;
  • Improves water quality;
  • Is non-toxic and safe to use;
  • Iron bacteria are generally resistant to chemical methods of control, but N-Fix is successful due to:
    • Its ability to complete the nitrification/denitrification process in reasonable period of time, so raising pH to start oxidising sulphur (S) by using CO2 present in media (water) as source of carbon and so decrease the number of iron bacteria present
    • Its high concentration

N-Fix Inline Bore Treatment Addresses Problems In Wells:

In wells, the major problems are:

  • Growths ‘plugging’ the screens
  • Coating of piped systems, impellers and motors, thereby reducing flow rates
  • Reduced potability of the water
  • Total plugging of the well encrustations of bore holes by:
    • Various species of Iron and manganese bacteria which exist in the soil could presumably enter a well during the initial boring operations or by seepage into the aquifer feeding the well
    • Sulphate reducing bacteria which reduce sulphates to sulphides to meet their respiratory needs (the sulphides when excreted react to form iron sulphide deposits)
    • Corrosion of metallic tubing and extension pipes
  • As with inline treatment, N-Fix Nutrient in application naturally eliminates these problems. We recommend that regular treatments be applied regardless of appearance, as iron bacterial spores can be transported undetected from one well to another

Evidential laboratory water testing results:

Results obtained from samples tested by an independent laboratory illustrate the changing composition of water sampling:

Manganese (Mg)Iron (Fe)
Mg/L Mg/L
Sample taken on 31/03/10 prior to first treatment (ID 001): 1.28 6.35
Sample taken on 14/04/10, 14 days after initial N-Fix Nutrient treatment 1.06 1.08
Sample taken on 05/05/10, over 1 months after N-Fix Nutrient treatment 0.17 3.66

Results from a microbiologist (illustrated below) also showed that filamentous bacteria in samples 000058-2 (taken 14/04/10) and 000058-3 (taken 10/05/10) contained highly refractive, brown coloured intracellular sulphur granules (positive) which means that filamentous bacteria present in the sample were oxidizing hydrogen sulphide (H2S) to sulphur (S) by using some of the CO2 present in the media (water) as source of carbon.

In summary, it was also noted that Sample ID 001 (taken 31/03/10 pre treatment) had 6 times higher number of filaments then Sample ID 002 (N-Fix Nutrient treated), and 10 times higher than Sample ID 003.
