A South Australian water company has developed a way to treat water without using chemicals.
Hydrosmart claims its technology uses microprocessors attached to the outside of underwater pipes that emit sound frequencies and clean the water to environmental standards.
The innovative solution was originally developed to stop minerals in the water such as iron and calcium sticking to the pipes.
It is now being used to reduce algae and balance Oxygen level at a sugarcane processing plant in the Eastern Thai province of Sakeo.
It prevents the serious risk of large amounts of harmful waste chemicals being washed into waterways and allows good bacteria in the water to thrive.
It is said to be highly efficient, only costing about AUD$10 (£6.12) a year, less than a standard light bulb. It also requires very little maintenance and can be left to run on its own for long periods.
A demonstration unit of the unique process cleaned a large tank of dirty water in only four weeks.
The plant now plans to install a full size model.
