This innovative Mor-sand filter boldly establishes an improved way of using an old technology in order to better safeguard the health of the poor in an environmentally ravaged region.  

The Mor-sand filter adopts the combined processes of coagulation and mechanical filtration to make water clean.  It markedly differs from other filters by its adoption of these processes and its combination of the individual strengths of slow sand filtration with the effectiveness offered by coagulation using Moringa oleifera powder.

It was piloted and clinically tested in Uboma and Isukwuato communities of southeastern Nigeria in late 2004. Various protocols were used for this evaluation. 

Both the Palintest protocol and Hach Ez Kit were respectively employed in the chemical tests while the membrane filtration principle was employed in the microbial tests. 

The Mor-sand filter yields an average of 80litres per day of safe drinking water. The reason for this performance is the extra finesse and expertise adopted in the sorting of the filtration grains (beds), such that the specific retention rate of water on the grains of each bed is drastically reduced.

Specific retention rates observed indicates: 

• Pumice/Gravel, 25% 
• Coarse sand, 20% 
• Fine sand, 25%
