FilterCork consists of a novel adsorbent material based on cork granulates coated with iron that can be used as a filling in filtering columns to treat drinking water contaminated by arsenic (As). Arsenic is a toxic element for human health; it is classified as a carcinogen by prolonged exposure, even at low concentrations, and can be widely found in groundwaters. More than 230 million people worldwide depend on arsenic-contaminated groundwater catchments for their drinking water.
This project aims to serve the needs of many companies and municipal services (in countries with centralized water treatment systems) or families that deal with the problem of As in their groundwater catchments and intend to treat these waters for consumption through As removal in adsorption columns, similar to filtering columns. The water is circulated in the column and purified, thereby becoming safe for consumption.
FilterCork is a natural (based on cork granulates, an abundant material in Portugal), ecological, and low-cost material. The technology has been tested on a lab scale with good results in As removal. Arsenic fixation in the granules is resistant, so these can be discarded easily at their end-of-life. The project aims to accelerate the business idea to provide a solution for the treatment of groundwater catchment waters efficiently, with financial, technical, and environmental advantages.
