In the thesis below, is research conducted on a compact potable water maker using desalination by reverse osmosis. In the first part there is a review of literature on the field of membrane technologies for desalination, the current system is also studied in depth. In the experimental part the salty water was prepared in a range of salinity from 0 g/l to 45 g/l and it was characterised through measurements of conductivity, pH value and water hardness. Besides water salinity, the operating pressure was also regulated in a range from 20 bar to 65 bar. After measuring the water parameters, noise level measurements were conducted. The measurements have shown that the value of salt rejection increases with the increase of operating pressure, that is why that kind of operating regime is recommended in cases with high demands for permeate purity even in regards to high necessary power values from the pump. It was also discovered that multistage microfiltration in the phase of pretreatment is not necessarily needed and it can be replaced with a single stage filter. In the final parts we suggest ways of reducing the system size and noise while maintaining similar potable water making capacities.
