  2. A Natural Way to Control Algae Blooms Diatomix is a natural solution to control nutrient levels as well as managing problem and toxic algae. Diatomix is a non-toxic, leading-edge nano-technology for water managing waterbodies. Before After

  3. How Does It Work?  By boosting diatom growth, Diatomix moves nutrients into the food chain  Diatoms can out-compete blue-green algae and other problem plant life for the Nitrogen and Phosphorus (N and P) in the water  N and P in the water are converted into zooplankton, invertebrates and fish biomass, so a healthy balance is restored to the waterbody

  4. What are Diatoms?  At the bottom of the food chain, diatoms are a diverse group of algae and are one of the most common types of organism found in oceans, lakes and freshwater ecosystems  Diatoms are a major food source for zooplankton which in turn are the primary food for invertebrates, fish, and other organisms.

  5.  Diatomix is a nano-silica based micro-nutrient liquid solution  1 litre of Diatomix promotes the growth of 200 to 1,000 kg of diatoms and can convert up to 80 kg of Inorganic Nitrogen into animal biomass (zooplankton, insects, fish, eels, birds, etc.)  Diatomix contains: Nano-silica and ten micronutrients: Iron, Manganese, Cobalt, Molybdenum, Calcium, Boron, Copper, Magnesium, Zinc and Potassium

  6. Council Trial STP site - Started 8 Feb 2016 Finished on 3 June 2016 • Dosing rate for the trial was 0.1 mL/m 2 /week • Total Blue Green Algae reduction was 99.4% by end of trial

  11. Council Trial STP site The New Plan • Controlling Blue Green Algae (BGA) with Diatomix works • Started dosing in winter before the problem arises, for easier control • Automated dosing station reduces OPEX and operator time

  12. Utility Trial Trialled at three of their sites Site 1 - Prior to trial start Four months into trial Dosing rates for trials ranged from 0.08 to 1.0 mL/m2/week depending upon the nitrogen concentration of the lagoon (11 to 37 mg/L Total Nitrogen)
