A nature-based solution for sewage treatment

Following an innovative biomimicry approach, the so-called green filter is a cost-effective solution to sewage treatment based on natural processes of contaminant degradation in wetlands. Together with the Global Nature Fund (GNF), Germany, Sika supports the implementation of green filters that purify between 0.8 and 1.4 liters of water per second, removing 86% of polluting components hereby significantly contributing to protection of rivers and lakes. At Lake Sampaloc, Philippines, a green filter cleans parts of the sewage of surrounding households. Sika and the GNF are supporting the use of Green Filters in further countries such as Colombia, Mexico and South Africa. Sika solutions for corrosion and concrete protection guarantee high durability of efficient wastewater systems.
