Utilities companies are placed under significant pressure regarding their environmental impact, cost of service and quality of supply from both consumers and regulators. Harmful micropollutants in both source water and wastewater streams require advanced treatment to ensure they do not cause damage to our natural ecosystems or human health.
Manufacturing residues, chemical waste products and even commonly consumed pharmaceuticals can be persistent against the final tertiary stage of traditional wastewater treatment and contaminated water can consequently be returned to the environment. This in turn can lead to regulatory performance penalties due to breach of compliance.
Drinking Water Treatment
Drinking water supplies can also contain micropollutants, including persistent pesticides such as metaldehyde. When this water is collected for distribution across a water network, it requires treatment to selectively remove the final hard-to-treat compounds that can persist even after activated carbon treatment. The advancement of water analysis techniques enables utilities companies to closely monitor for known substances as well as emerging contaminants of concern and a new approach to treatment is required to tackle these effectively.
