Description of materials of construction
Jal-TARA is based on slow sand filtration technique. Two types of filtration processes take place: physical filtration which prevents organic matter, silt and mud particles and biological filtration scavenges and breaks down unwanted pathogens and organic matter. Jal-TARA removes bacteria and turbidity up to log scale 2-3.
