In 2015, only 55% of people in rural areas had access to water free of contamination, and microbial contamination remained the main concern. However, water quality data was available only for 45% of the world population (World Health Organization & UNICEF, 2017). Turbidity which is caused by suspended chemical and biological particles can be an indicator of pathogenic microorganisms’ presence while being measurable easily, quickly and cheaply. It is also a recommended measurement assessing the drinking water quality according to the WHO Guidelines for Drinking-water Quality (World Health Organization, 2017). Filtration is considered the most practical technology for reduction of turbidity, and hence suspended particles removal in drinking water application (US Environmental Protection Agency, 2003). This work is part of SAFEWATER research project (www.safewater-research.com), which aims to deliver clean drinking water to rural communities in Mexico and Colombia.

As communities of interest dislike the addition of chemicals to their drinking water, a cost-effective benefit of using cartridge filters is that they are commonly used without the addition of costly coagulants/flocculants (US Environmental Protection Agency, 2003). These filters are disposable media suitable for small systems (Hand, Tchobanoglous, Howe, Trussell, & Crittenden, 2012). Therefore, this pilot study investigates the efficiency, hydraulic performance and lifetime of low-cost commercial cartridge filters for removal of turbidity...
