A few intake stations have vibration problems caused by pumps, motors and pipes. The vibration transffered from pumps, motors and pipes excites buiding severely. Therefore, the crack is generated on building wall and people who work at intake station are damaged. In this paper, the vibration and noise have been measured and analyzed for pumps, motors, pipes and building at intake station. Also, the cause of vibration and noise is identified. Finally, the reference of vibration and noise is established using results of measurement.

Filtration is fundamental unit operation aimed at the separation of solids from the suspension by means of porous medium that retains the solids and allows the liquid to pass. Cake filtration is widely used in industry to separate solid particles from suspension in liquid. When the cakes are used as products in actual field, the solid-liquid separation has some problem such as high concentration cake, contamination of flocculants and batch type process of filtration. In this study, it has been developed the high performance cake-less filtration system whose condensed slurry layer maintains fluidity. The development of this novel filtration system allowed us to be unnecessary the scrapping operation of cake as well as to collect the high condensed slurry with more easily. These results clearly show that the new device will be realized for the making high condensed and fluidity slurry. It could be confirmed that the concentration of condensed slurry achieved 35 vol% with slurry fluidity. It is demonstrated that if particles are well dispersed, condensed slurry by filtration can be drained without scraper. In our new filtration system (DECAFF system), the specification of the system and operation conditions can be determined from a pre-filtration test.
