ABSTRACT
Introduction: Reverse osmosis (RO) is a water purification process that uses a partial permeable membrane to remove ions, unwanted molecules and larger particles from drinking water. In reverse osmosis, an applied pressure is used to overcome osmotic pressure, a colligative property that is driven by chemical potential differences of the solvent, a thermodynamic parameter. In the process of reverse osmosis the amount of water that is drained is a concern area for the people using the R.O. filtration device in their household because it wasted about 70% of the water to purify just one liter of water. This R.O. waste water can be utilized for various purposes such as washing vehicle like car bike etc, cleaning toilet this study is aimed to assess the knowledge reverse osmosis waste water utilization among general public at Indore. Objectives: 1. To assess the pretest knowledge regarding reverse osmosis (R.O) waste water utilization among general public. 2. To assess the posttest knowledge regarding reverse osmosis waste water utilization among general public. 3. To evaluate the effectiveness of structured teaching program on reverse osmosis (R.O) waste water utilization among general public. Hypothesis: H1- there will be significant difference between pretest and posttest knowledge who received structured teaching program regarding the utilization of waste R.O water. Materials and Methods: Quantitative, pre-experimental, one group pretest posttest design was adopted for the study. Total of 60 general public selected by using simple randomized sampling technique was used. Description of Tools: Structured knowledge questionnaire. Result: Data was analyzes using descriptive and inferential statistics. Major Finding: In the pre-test majority of the sample (44 out of 60, 73.3%) had inadequate knowledge and in the post-test, majority (54 out of 60, 90%) had adequate knowledge regarding reverse osmosis. A paired‘t’ test was done and it showed a‘t’ value of 22.34 at 0.05 level of significance, this indicates the effectiveness of structured teaching programme in enhancing the knowledge of the general public. There was no association found between the mean pre-test knowledge of the general public. There was no association found between the mean pre-test knowledge scorer with the selected socio-demographic variable such as age (?2 = 8.643), gender (?2 = 4.455), education qualification (?2 = 4.706), Occupation (?2 = 2.531), number of family member (?2 = 5.653) and previous knowledge about reverse osmosis filter water (?2 =0.393). Conclusion: There is a significant difference between the mean pre-test and post-test knowledge score among general public regarding reverse osmosis waste water utilization.
