A study of leaching tests for cement stabilised waste
A cement-stabilised waste was subjected to batch, column, and dynamic leaching tests, and the leaching behaviour of arsenic, copper, lead, selenium, and zinc was investigated. Batch tests included the Australian Bottle Leaching Procedure (ABLP, AS 4493.3-1997), Toxicity Characteristic Leaching …

An investigation of methods to reduce solvent emissions, for the printing of flexible packaging substrates
The flexographic and gravure printing houses are the major suppliers of flexible packaging substrates, which are principally based on solventbased ink systems. The Environment Protection Authority (E.P.A) has issued a Code of Practice, in 1990, that targets the Victorian flexographic and gravure …

Microbial degradation of high molecular weight polycyclic aromatic hydrocarbons
The bacterial degradation of high molecular weight PAHs was investigated by isolating communities and individual strains from a PAH-contaminated site. Microbiological analysis of soils from Port Melbourne, Australia, resulted in the enrichment of five microbial communities capable of degrading …

Hydraulic conductivity and chemical compatibility of some Victorian soils used as liners for waste containment
… of the clay is a governing parameter and many environmental regulations require this parameter to be less than 1x10"' m/s. Therefore, the precise assessment of hydraulic conductivity and the compatibility of the liner material with the permeant or leachate encountered, is paramount to ensure …

Methodologies for the analysis of petroleum hydrocarbons extracted from contaminated soils
Australian research into TPH and BTEX test methods has, to date, not been coordinated and no standard methods have been agreed to. Overseas research also lacks acceptable solutions for the standardisation of TPH and BTEX methodologies. Since Australia carries out many thousands of analyses of TPH …

Directions for best management of Kangaroo grass (Themeda triandra Forssk.) re-establishment in southeastern Australian native grassland remnants
Western basalt plains native grasslands, which extend from the west of Melbourne in Victoria to the South Australian border, are recognised as one of the most threatened ecosystems in Victoria (DC&E 1992). Ecosystem functions and their ability to support life are disappearing along with the remnant …

Short term planning and operation of irrigation systems
In recent times, with regards to rural water supplies in Victoria and most other parts of Australia, emphasis is placed more on efficient use of existing water resources than on new resource developments. This is especially true for irrigation systems. This emphasis is mainly due to limited funds …

Parameter optimisation of river water quality models using genetic algorithms
Rivers can provide valuable supply of drinking water for humans, irrigation water to farmlands, water for hydropower and home for many aquatic ecosystems. However, due to population increase and its adverse effects on the rivers, inappropriate farming activities in the river catchments, and other …

The design and control of anaerobic ponds with specific reference to Western Treatment Plant
This thesis reports results of a study of the control and improvement of the covered 115E Anaerobic Reactor at Western Treatment Plant. The 115E Reactor treats 60 ML of sewage per day and produces methane which is harvested for power production. The objectives of this research were to identify ways …

Light scattering by smoke and nuisance aerosols
This study was aimed at discriminating between three classes of aerosols, namely those generated by flaming and non-flaming (smouldering and forced pyrolysis) fires as well as nuisance aerosols. This was undertaken using a scattering cross section based on the mass concentration of aerosols as …

The development of hydraulic ram for village use in developing countries : a dissertation submitted for the degree of Diploma in Natural Resources, Lincoln College and University of Canterbury
A hydraulic ram may be described as a simple, noisy, self-operating/automatic and efficient water raising machine. It is also a unique and interesting pumping device which combines the quality of prime-mover and pump. The assembly of the different components of a hydraulic ram is shown in Figure 1. …
