Drinking water supplies can contain harmful micropollutants, including persistent pesticides such as metaldehyde. These hard-to-treat micropollutants  require advanced treatment to selectively remove the compounds and ensure they do not cause damage to our natural ecosystems or human health.

The treatment process for drinking water varies according to the type and quality of the raw water. Common treatment methods include aeration, flocculation, sedimentation, filtration, and disinfection to ensure water is of a safe quality for consumption. 

The advancement of water analysis techniques enables utilities companies to closely monitor for known substances as well as emerging contaminants of concern when a new approach to treatment is required to tackle these effectively.

Arvia Technology has built up long-lasting and successful partnerships with utilities companies who have struggled with the treatment of drinking water containing micropollutants, natural organic matter (NOM) and colour, which are a concern for both end consumers and regulators.

Hard to treat pollutants found in drinking water supplies include:

Pathogens – disease-causing organisms that include bacteria, amoebas and viruses.

Harmful chemicals from human activities and industrial wastes such as pesticides and fertilisers.

Chemicals and minerals from the natural environment, such as arsenic, common salts and fluorides.

Some non-harmful contaminants including zinc and iron may influence the taste, smell, colour and turbidity of water.
