Drinking water treatment - Alternative filter materials for slow filtration

As part of the collaborative project to optimise slow filters and extend their applications, researchers in this subproject are studying the cleaning capacity of alternative, cost-effective filter materials. Recycled glass granulate and coconut fibres proved to be suitable. However, in outdoor studies only coconut fibre filters produce drinking water that meets WHO standards from the untreated water used.
