The performance of a combined biological aerated filter (BAF) and an ultrafiltration (UF) system for the treatment of real and synthetic greywater, settled sewage, rainwater and borehole water has been assessed at both full-scale (at the Millennium Dome Water Recycling plant) and bench-scale. Irreversible membrane fouling was explained at bench-scale in terms of a simple but novel model whereby a proportion of the membrane area is progressively blocked, in proportion to the square root of the transmembrane pressure.

Abstract:

Urban water recycling has been promoted as one of several ways that water use efficiency could be improved in Australia???s cities, but few such schemes have been introduced. Many urban water-recycling schemes have been proposed, but often, these projects have been rejected because of community opposition. These difficulties suggest that recycling water is not just about having the right answer to any problem, but about the way in which the question is addressed. It is concerned with how practice is institutionalised; not just the rule making, but also the understandings and values that make t

Abstract:

Sustainable algae biofuel production is rising in demand, and the need to establish an efficient and proper algae harvesting method is extremely essential. Membrane filtration technology seems to be the most promising as a solid-liquid separation process. However, fouling seems to be the major problem for membranes. There is limited research on how to solve the problem of fouling, and cake buildup inside the membranes. A novel membrane design is required to solve the problem of fouling and cake buildup inside the membranes. The objective of this research is to construct a novel two way membran

Abstract:

Coal seam gas associated water (CSGAW) which is a main by-product of CSG production typically contains significant amounts of salts. The chemical composition of CSGAW is complex and may also contaminated with drilling chemicals contain heavy metals, carcinogens such as benzene, toluene, ethylbenzene and xylene, and radioactive elements like uranium. CSGAW has potential environmental issues; therefor it is unsuitable for further uses without proper treatment. The release of CSGAW to the land and rivers without proper treatment may drown vegetation, and endanger the aquatic life and environment.

Developing nations face insurmountable challenges to reliably and sustainably provide energy and water to the population. These resources are intricately entwined such that decisions on the use of one affects the other (energy-water nexus). Inadequate and ageing infrastructure, increased population and connectivity, urbanization, improved standards of living and spatially uneven rainfall are some of the reasons causing this insecurity. Expanding and developing new supply infrastructure is not sustainable due to sky high costs and negative environmental impact such as increased greenhouse gas e

Abstract:

With the drive to reduce water usage globally, the mining sector must reassess its water usage as it has in the past contributed greatly to environmental degradation due to effluent discharge, tailing disposal and process water seepage into the water-table. Mineral beneficiation entails different unit operations; amongst them is froth flotation. Froth flotation is a multifaceted complex process which is water intensive and to manage water usage, the global mining industries are now recycling water.

San Diego imports 80 to 90 percent of its water supply, depending on conditions during any particular year. This high level of imports and low diversity of water supply have combined with climate change to generate an urgent need for increased conservation and diversification of San Diego's water supply. Water reuse is one option to mitigate this problem. An attempt was made in the early 1990s to recycle wastewater but the public reacted badly due to a combination of bad public relations, perceived environmental justice issues, and a psychological phenomenon called the yuck factor.

Abstract:

To be environmentally sustainable, algae biofuel production requires extensive recycling of water and nutrients during algae cultivation. Such recycling can be in the form of reuse of external wastewaters, such as from municipal sewers, but, to achieve significant biofuels production, internal recycling at the algae farms is also needed. A potential difficulty with internal recycling is the accumulation of auto-inhibitory compounds in recycled algae pond water. An additional concern is that nutrients in the residuals from algae biofuel manufacturing will be only partly bioavailable. Both these

The pervious pavement system has been identified as an effective source control device capable of removing urban stormwater pollution by trapping pollutants within the system and biodegradation. Recent studies have further demonstrated that the pervious pavement system could be used as a source of renewable energy capable of reducing household energy bill by about 80%. In view of ever increasing demand for water and the continued reduction in available fresh water resources in the world, stormwater has been recognized as a potential valuable source of water which could be harnessed.

Abstract:

Water resources are known to contain radioactive materials, either from natural or anthropogenic sources. Treatment, including wastewater treatment, of water for drinking, domestic, agricultural and industrial purposes has the potential to concentrate radioactive materials. Inevitably concentrated radioactive material is discharged to the environment as a waste product, reused for soil conditioning, or perhaps recycled as a new potable water supply. This thesis, presented as a collection of peer reviewed scientific papers, explores a number of water / wastewater treatment applications, and

碩士<br>正修科技大學<br>電子工程研究所<br>102<br>This paper is focus on developing a wastewater recycling system that allows a single floor scrubber machine greatly enhance cleaning area, it not only can improve efficiency and save more power and operating time but also achieve environmental protection and water conservation purposes. Floor scrubber according to their system functions can be broadly divided into four parts, which are cleaning equipment, mechanical structure, electronic control systems and filtration circulatory system. Cleaning Equipment subsystems use scouring disk pads, round brush with cl

碩士<br>義守大學<br>生物技術與化學工程研究所<br>100<br>The main purpose of this research is to study whether polyethylene glycol remains after cutting wafer in order to recycle and reduce the cost and raise its utility rate. We also explore polymerization of ethylene glycol and sulfuric acid to find the optimum synthetic conditions. We use Gel Permeation Chromatography (GPC), Fourier-Transform Infrared Spectrometer (FT-IR), Gas Chromatography-Mass Spectrometer (GC-MS) and Nuclear Magnetic Resonance Spectrophotometer (NMR) to characterize the commercial waterborne cutting fluid getting its components. Then, the
