Silver Ceramic Water Filters (SiraWafil) are a portable drinking water treatment technology using ceramic filters coated with silver nitrate to produce clean and safe water. SiraWafil can effectively remove bacteria and protozoa through filtration and silver's antibacterial properties. They are affordable and can be produced locally involving communities. This helps provide access to clean water, prevents waterborne diseases, and empowers communities, working as sustainable solution particularly for remote areas lacking access to clean water in Indonesia.

11. How Sirawafil Can
Prevent Waterborne Disease
Filter Mechanism
Silver Coated
Mechanism
filtration by size exclusion
removes
larger microorganisms.
Silver Nitrate (AgNO3) inactivate
pathogens that pass through the filter
pores, which limit bacterial growth in the
filter itself (bacteriostatic), or exert other
effects of benefit to disinfection.

16. Conclusion
SiraWafil, a portable drinking water treatment
technologies as an effective and sustainable point-of-use
water treatment technology for the developing countries.
The coating process of silver nitrate (AgNO3) and other ingredients
(MgO) can inhibit bacteria, protozoa, and other microorganisms
effectively, thus can prevent water borne disease.
Benefit : Affordable, Effective, Easy to implement, Involving
the community throughout the process
Leads to sustainable
“Arisan SiraWafil” Marketing strategy
