Abstract

Many people commonly are using surface water as the main source for clean and drinking water.
Ironically, the quality of surface water decreases from time to time due to domestic and industrial
pollution. Earthen pots with colloidal silver applied on their surface created simple coated filters where the
silver coating serves as a disinfectant that render the product water ready for consumption.
This is a descriptive pre-experimental research, using one group pretest-posttest design, that is
to evaluate water treatment to produce water ready for consumption by analyzing the water quality,
before and after treatment with the unit, especially with regard to physical and microbioloqical parameters
according to PERMENKES/N0.492/ MENKES/PER/IV/2010re: drinking water quality requirements.
Measurements indicated that pottery filter with a mixture of clay-bran 40% is fastest flow
filtration flow filtration, which meant 5 liters of filtrate out in 21 minutes. Meanwhile a mixture clay-wood
20% with an average flow of (Q) 0.254 It / jm was slowest.However clay-rice bran mixture 20% was the
most is stable. Result of microbiological examination on pond water (raw condition) indicated a Coli MPN
Index of >2400, and E Coli index of 1600. After filtration with six pots coated with colloidal silver
significant reduction ini microbiological parameter was observed, indicated by MPN. Coliand E Coli indices
of O. Initial (physical) condition of the pond water have indicated no odour, no colour, no taste, and the
turbidity level was 11.78 NTU, TDS level was 142mg/L, temperature was 27°C and pH 5.5. After passing
through six filter pots coated with silver colloids, physicsl parameter i.e. TDS and turbidity decreased, and
pH was normal.
With respect to Permenkes No. 416/1990 and Permenkes No. 492/2010 on requirements for
potable water and drinking water respectively, suggestion for follow up research on filter pots coated with
colloidal silver pertaining to the chemistry parameters.
