| Abstract |
| In this study, the hydraulic stability of lab scale tankless water treatment system was evaluated. This system consists of dummy membrane filtrations, AC filter, backwashing pump, air compressor, supply pump, pressure and flow-rate control valves, water supply tank. The experiments were carried out with 4 cases related to the set-up of pressure, in-going flow-rate and closing status of upper valves of dummy membrane filtration. As the results of experiments, in the case of relatively low preset in-going flow-rate of 10 l/min. the pressure preset from 2.0 bar to 3.0 bar is increased, the flow-rate in the system was stable during the period of experiment but the pressure was very unstable. In the case of the in-going of 20 l/min, the flow-rate and pressure were slightly more stable than the case of the in-going of 10 l/min. In the partially closed case of upper valves of membrane filtrations, the fluid in the system flows with bigger pressure than in the completely opened case. |
