Enzymatic treatment for controlling irreversible membrane fouling in cross-flow humic acid-fed ultrafiltration.

Exploring reasonable ways to remove foulant is of great importance in order to allow sustainable operation of ultrafiltration (UF) membranes in water/wastewater treatment technology. Compounds of organic and inorganic origin largely contribute to irreversible fouling. This study attempted to remove problem of UF membrane fouling by using four different enzymes including alpha-amylase, lipase, cellulase and protease.

Effects of TiO2 dosage, pH and temperature on decolorization of C.I. Reactive Red 2 in a UV/US/TiO2 system.

This study elucidates the decolorization of C.I. Reactive Red 2 (RR2) in ultrasound (US), US/TiO(2), ultraviolet (UV)/TiO(2) and UV/US/TiO(2) systems.

Development of a dynamic strategy planning theory and system for sustainable river basin land use management.

Land use management is central to government planning for sustainable development. The main purpose of this study is to develop a novel strategy planning theory and system to assist responsible authorities in obtaining alternatives of sustainable top river basin land use management. The concepts and theory of system analysis, driving force-state-response (DSR) framework, and system dynamics are used to establish the DSR dynamic strategy planning procedure in this work.
