Mineral-based filters are removing bacteria and other contaminants from drinking water in the developing world.
More than two billion people around the world live without direct access to safe drinking water.
In the developing world, access to clean water services is a matter of survival. And it also has a profound social and economic impact: Untreated water causes infectious diseases that prevent people working. And if their children get sick, medicine is expensive.
The most serious cases of waterborne diseases such as typhoid, cholera and dysentery can be fatal. Diarrheal illnesses, which cause severe dehydration, kills half a million children under the age of five every year.
In some areas, accessing hygienic water is an everyday struggle. Elsewhere, freshwater resources are unexpectedly impacted because of a natural disaster or conflict.
During a crisis, simply getting relief materials to families can be a challenge. These families often rely on community-based water supply and filtration systems, which allow them to fill buckets of water to bring home – but there is a significant risk from point-of-use contamination. Every time a glass or hand is used to draw water from the storage bucket, the water may be re-contaminated.
Imerys is using its technical knowledge of filtration and minerals to help tackle this critical health and social issue.
ImerPureTM is its low-cost water treatment and storage system, which is helping low-income households and communities that lack basic water sanitation. It is a ceramic filter cartridge based on filtration aids that Imerys supplies to its beverage customers. Containing the mineral diatomite, the cartridge purifies highly turbid and contaminated water.
Research has proven ceramic to be an effective, simple and low cost filter technology for disease-causing microbes and other pathogens. Imerys carried out lab and field trials over three years to develop an optimized combination of diatomite, and binders for a fast flow and removal of microbes.
Humanitarian and disaster relief organization Global Medic uses ImerPure cartridges in its filters, and has distributed tens of thousands to refugees and families across the world who have been affected by floods or displaced from their homes because of war or other disasters.
There is a clear social need for filtered water. Wider access to filtered drinking water can help break the poverty cycle. It reduces the likelihood of illness and increases families’ ability to work, raise income and send their children to school.
The lithium-ion battery market has vastly expanded in recent years and our Graphite & Carbon business is fully committed to support this market growth.
Fonducrete® – an engineered calcium aluminate cement – is reducing costly maintenance and repair work in sugar mills.
Filtration is a commonly observed practice by winemakers across the world. For decades, minerals such as diatomite and perlite have played a vital role in the process – removing unwanted substances and leaving wine producers with clear, quality wines.
