The TWC Block technology – How it Restores Water Ecosystems


TWC treats polluted and unhealthy water systems by combining bioremediation technology and best management practices to restore the natural balance of an affected waterways microbiology ecosystem.


The Nitrogen Cycle


Health water ecosystems require a healthy “nitrogen cycle”. The nitrogen cycle is where the beneficial bacteria Nitrosomonas and Nitrobacter bacteria are responsible for transforming our waste from toxic ammonium into nitrite and then into relatively nontoxic nitrate. Nitrate is then consumed or removed in many ways including as nutrients for wet lands or it can be converted to nitrogen gas. Good water quality, fish health and weed control all comes down to maintaining the nitrogen cycle’s speed and health in any water environment and in turn this requires a favourable habitat for beneficial bacteria that assist the nitrogen cycle.


The TWC Block & Bacillus


This favourable habitat for beneficial bacteria is delivered by TWC through carbon trace elements infused in a wax block (TWC block). The TWC block contains millions of microscopic capillaries that act as a protective home for all beneficial bacteria and the carbon trace elements act as a catalyst for their growth. Importantly, this creates ideal conditions for the proliferation of the key bacterial species Bacillus to an extent where their colonies form a microbial mat. Bacillus is a key element of the TWC bioremediation process.
The carbon trace elements in the TWC blocks activate a natural doubling time in Bacillus. Under laboratory conditions one Bacillus bacteria becomes 8,000 in 10 hours. With our natural doubling time, one bacteria becomes 8 million in 10 hours.
This produces the following results:


  • The populations of Bacillus are able to convert nutrients such as phosphorus into forms which become available for other beneficial organisms to consume whilst restricting detrimental species such as E-coli and Cyanobacteria.
  • Bacillus produce enzymes which split nutrient cells down to a size that the nitrogen cycle bacteria can consume. When you have a nutrient overload the small nutrient cells re-attach to the larger ones and this becomes a nitrification inhibitor as the nitrogen cycle bacteria cannot consume these larger nutrient cells.
  • The TWC block activation of the doubling time in Bacillus allows more enzyme production to cope with the excess nutrient load, splitting the cells back down to a size the nitrogen cycle bacteria can consume, and producing biological nitrate as energy for diatoms and microalgae which then naturally restricts cyanobacteria (blue green algae).
  • Once the cycle of cyanobacteria has been broken the whole aquatic ecosystem is able to regenerate.
    The restoration of the aquatic ecosystem also means that the nutrient loads in the lake, reservoir, river, canal, or treatment ponds is greatly reduced
