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.

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
increase the community participation in household level,
especially in the lack of clean water areas in Indonesia.

Hinweis der Redaktion
World Health Organization (WHO) recorded in 2008, approximately 1.1 billion people worldwide were lack of access to clean water and 2.3 billion people live in areas of water shortage.
80% of disease in the world is caused by contaminated water
Until now, the high cost of water treatment technology are not accessible and reachable by people in remote areas.
E.g : Solar Disinfection, slow sand filter, Water Chlorination, dan flocullant. (CDC, 2011).
This public health problem needs to be given an alternative solution, one of the solution is Silver Ceramic Water Filters.
Turbidity of pre-filter water ranged from 5-300 NTU.
With this SiraWafil, the Turbidity of filtered water will always < 5 NTU.
Water Sources : ground water, well water, water pipe, rain water, or tap water.
Coated with Silver Nitrate (AgNO3) : AgNO3 can inhibit bacteria, protozoa, and other microorganisms effectively, nearly 100%.
Effective remove 100% of the total coliform and fecal coliform, 99.99% protozoa, and 99% of E. Coli
Involving the Community & NGO : - Citizen can be involved in the production process, - NGO can be involved in the production, distribution, and monitoring process. –> Creates a sustainability by involving citizens and NGO

Easy to use & Easy Maintenance
Diganti-> Banyak penduduk yang masih sulit air bersih
Filter ini bukan segala galanya. Harus dimasak agar bebas kuman. Takut terkontaminasi
Masak hanya mematikan kuman, mineral, kontaminasi lainnya tidak tersaring. Air itu sesuai baku mutu harus memenuhi baku mutu fisik, kimiawi, biologi. Air ini juga bisa dipakai untuk minum, cuci tangan, dll.
Masih banyak mdgs belom
-masy sulit diajak berpartisipasi karena terbiasa menerima intervensi dari pemerintah. Dan turut serta berperan dalam pemerintahan
