| dc.description.abstract | In the data analysis presented the main problems, what should be fixing in the future. The first step is to investigate all the water quality measuring devices at the process lines. Especially at process line D, because the pH measuring contains failures, when the membrane system starts to backwashing. Not only can be the problem with the measuring instruments or their gadgets, but also if the interface contain bugs between the instruments and the regulation system can cause communication problems and services bad data for the remote control.
The main problem in the treatment plant is the number of backwashing which derived from the fouling and clogging of the membrane. Not only the problem the fast cake layer forming on the plan, which cause bigger particles such as hair or chewing gum, which amount is highly depend on usage of pool. The fouling t due to the smaller particles which captured the in the filter pores is also important. April is the best example when the number of the visitors was less than March, but the number of backwashing was larger, which can cause the pore constriction (section 2.6.1). As a result to reduce the number of backwashing, it needs to pre-treat the feed stream before the ceramic membranes. At process line D case where the number of backwashing was extraordinary high should consider the backwashed water treatment, thus reduce the amount of wasted water by backwashing. | en |
