High recovery water reclamation process

Global water use has been increasing at a rapid rate due to population growth, and more areas are facing severe water scarcity. The conversion of wastewater into reusable water has been gaining attention as it is an important source of water. In water reclamation, reverse osmosis (RO) is the key technology in treating wastewater for reuse. However, membrane fouling by organics, inorganics and biological substances, has continuously hindered the membrane performance. Moreover, high RO recovery is necessary to increase the amount of product water. However, at high recovery, RO fouling is often exacerbated as the more concentrated retentate stream increases the fouling potential. Thus, the foulant compositions, fouling mechanisms and RO feed water quality at high recovery lab-scale RO processes were analysed in this study. The different types of RO feed water quality were obtained from pre-treatment with a novel nanofiltration-membrane bioreactor (NF-MBR) and an ultrafiltration-MBR (UF-MBR). The large increase in trans-membrane pressure (TMP) revealed the higher fouling rate was associated with high recovery as well as the lower feed water quality in terms of dissolved organic carbon (DOC) that was treated by UF-MBR. On the other hand, 90% RO recovery was achievable with the NF-MBR permeate which has lower DOC despite higher Ca & P content under the concentration factor effect. Results obtained showed that the combined effects of organic-inorganic fouling during high recovery RO processes could be observed as a dense fouling layer was formed with high amount of extracellular polymeric substances, ATP, Ca-P etc.Bachelor of Engineering (Environmental Engineering

The stock price behaviour of Chinese markets : a preliminary study

The emergence of the Chinese equity markets provides new opportunities for investors to participate in the economic boom in China. These markets exhibit high expected returns as well as high volatility. This research examines the daily return behaviour of the four China share indices: the Shanghai A-share Index, the Shanghai B-share Index, the Shenzhen A-share Index, and the Shenzhen B-share Index. By using daily data of these share indices from March 1993 to December 1994, the results show that weak form efficiency does not exist in the Bshare markets. Segmentation is found between the two B-share markets but not the A-share markets. This gives evidence that macro-economic factors of China affect the two A-share markets concurrently. There is evidence that the returns of the A-share indices lead the returns of the B-share indices. As for the two A-share markets, it is found that the Shenzhen A-share returns lead the Shanghai A-share returns but not vice versa. Both the B-share returns are shown to have bi-directional lead-lag relationship. This research further extends the analysis between the B-share indices with the Standard and Poor's 500 Index and the Hang Seng Index. No correlation exis ts between the China markets and the two foreign markets. It is found that the returns of the foreign markets do not lead the B-share markets.BUSINES
