Test kit for Microbiological Quality of Drinking Water is a simple device to test the potability of drinking water. This test does not need any any laboratory facility. It is inexpensive, reliable and convenient method of testing in field conditions. Waterborne diseases like typhoid, cholera, diarrhoea and jaundice are caused by polluted water supply. The conventional method of testing the micro biological quality of water needs the service of a qualified microbiologist, laboratory facilities and takes 72 hrs. to know the result. Further getting this test done in the laboratory is expensive.But this test kit is cheap and has a great market potential.

The process is based on the detection of H2S producing organism in drinking water which are present alogwith coliforms. The process is the preparation of 20x concentrated media by mixing some chemicals in a definite proportion. Dry and sterile media is provided in the screw capped bottle which is ready for use. The water to be tested is filled upto the upper level of the bottle and bottle is gently shaken for 5 minutes and kept at room temperature for 18 hrs. The bottle can also be kept in the pocket while sleeping at night. The following changes indicate the results.

PROCESS

They can be proportionately scaled up for large scale production by only increasing the ingerdients. One ml portion of this solution is absorbed on a folded tissue paper (80 sq. cm.), which wasplaced in a Mcc Cartney bottle sterilized in Autoclave and dried at 50 degree Celcius under sterile condition.
