Clay-biodegradable polymer combination for pollutant removal from water
Summary: In this study, the use of clay in combination with biodegradable polymeric flocculants is investigated to remove micropollutants from wastewater effectively. Experimental studies were carried out with four different clays to select the best clay for further optimisation. The removal achieved is in the range of 10-99% based on the clay concentration of 10 mg/L-50 g/L. The clay flocculation efficiency test leads towards 80-84% of the clay being flocculated by the polymer from the water matrixes.

Household water treatment and safe storage – effectiveness and economics
Summary: Household Water Treatment and safe Storage (HWTS) systems aim to provide safe drinking water in an affordable manner. The effectiveness of these systems to remove pathogens is crucial for the health of its users. Different researches report wide ranges of effectiveness for each of the three selected systems: SODIS, ceramic and biosand filters. The resources available for the prices of HWTS also report wide ranges. In the data available no relation was observed between price and effectiveness.
