Solutions for municipal water and wastewater

Climate change coupled with population growth result in wastewater becoming an increasingly critical challenge for all councils and water utilities.

A growing sewer network create issues such as infrastructure damage, odour complaints and potential health and safety hazards, as well as accelerated corrosion of sewer assets, pump station wells, discharge manholes and treatment plants.

Trends and challenges facing water utilities today

With rapid urbanisation and development, there is an increasing pressure on water utilities to find safer and more sustainable solutions to prevent odour, protect existing and new infrastructure, and improve wastewater treatment performance.

A fast-growing sewer network and the disposal of untreated or poorly treated wastewater in natural waterways can lead to dramatic consequences on biodiversity, the quality of our water resources and the health and safety of people.

While wastewater management and pollution prevention are a priority, waste-to-energy programs can also help improve the productivity of treatment facilities by maximising the economics of biogas generation from anaerobic systems.

Our solution

ACTI-Mag, a high surface area magnesium hydroxide solution

ACTI-Mag is non hazardous, non-toxic and has a very low solubility, which makes it perfect for acid neutralisation, and hydrogen sulphide gas (H2S) control in sewers, while maintaining the water quality for any kind of downstream use.
