Emerging Challenges of Micropollutants in Wastewater

In this article we examine the challenge of micropollutants in wastewater. These substances are becoming an increasing concern due to their potential impact on both the environment and human health. They are found in trace amounts in water bodies but can have significant long-term effects.

Micropollutants in Wastewater

Micropollutants are a diverse group of organic and inorganic substances found in water at extremely low concentrations-typically in the range of nanograms to micrograms per litre. Despite their minute quantities, they can have significant impacts on both human health and the environment.

What Are Micropollutants?

Micropollutants refer to a diverse group of substances, including pharmaceuticals, personal care products, pesticides, and industrial chemicals, which are present in the environment at low concentrations. Despite their minute presence, they can be highly persistent and bioactive.

• Pharmaceuticals: Medications excreted by humans and animals.
• Personal Care Products: Ingredients in cosmetics and cleaning agents.
• Industrial Chemicals: Byproducts of manufacturing processes.
• Agricultural Runoff: Pesticides and fertilisers washed into water bodies.

Risks to Health and Environment

Micropollutants pose significant risks due to their ability to disrupt ecosystems and potentially affect human health.

Water which has been inadequately treated and contains micropollutants has far reaching consequences; from antimicrobial resistance to population decreases in aquatic species and the bioaccumulation of micropollutants in the food chain.

They could pose a variety of threats to the environment, human health, and the viability of public/industrial wastewater reuse.

• It can lead to a build-up of dangerous chemicals in the environment which can be damaging to the wildlife.
• Potential contamination of rivers, borehole and underground aquifers which are relied as a source of drinking water.

Environmental Risks

• Ecosystem Disruption: Micropollutants can affect aquatic life, disrupting reproductive systems and growth patterns.
• Bioaccumulation: These substances can accumulate in the food chain, affecting predators and potentially reaching humans.

Human Health Risks

• Endocrine Disruption: Some micropollutants mimic hormones, interfering with endocrine systems.
• Antibiotic Resistance: Residual pharmaceuticals can contribute to the development of antibiotic-resistant bacteria.
• Chronic Exposure: Long-term exposure may lead to health issues, although more research is needed to fully understand these effects.

Arvia’s Treatment of Micropollutants

Addressing micropollutants in wastewater involves advanced treatment technologies. Arvia’s onsite Nyex™ Treatment Systems provide an industrial wastewater treatment solution in various applications relating to wastewater discharge, wastewater recycling and source water applications around the world.

Arvia’s design specialists optimise each system to preferentially treat the micropollutants found in your wastewater stream, enabling the treated water to meet individual discharge regulations. In most cases, treated water is also safe for reuse as process water within the business. This saves utility costs and boosts positive Corporate Social Responsibility as pressures rise in relation to sustainable operations.

Nyex™ systems can be installed as a standalone treatment or retrofitted into an existing treatment train. This is of particular benefit when water is extracted for distribution by utilities companies as micropollutants found in source water can surpass traditional treatment.

Conclusion

While micropollutants in wastewater present challenges, understanding their sources, risks, and treatment options is crucial for protecting both human health and the environment. Continued research and innovation in treatment technologies, alongside effective regulatory strategies, are essential in mitigating their impact. Through a combination of advanced treatment methods and proactive prevention measures, we can address the complexities of micropollutants and strive for a safer, cleaner future.
