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. After Before

SLIDE 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

SLIDE 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

f 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.

SLIDE 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

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

Site 1 - Prior to trial start Four months into trial

Utility Trial

Trialled at three of their sites 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)
