IUWM aims to utilize all water resources (stormwater, wastewater, and rainwater) based on fit-for-purpose concepts. Here, a local water utility in Melbourne’s Melton growth area explored the availability of stormwater as an alternative water resource for water service planning for a proposed residential development in an existing greenfield area of 13,890 hectares for 160,000 new houses by 2040. A methodology was developed for assessing the stormwater quantity and quality under land use change and different climatic conditions considering the availability of stormwater from the proposed urban development. The modelling results indicated that the amount of annual stormwater generated in the region increased by nearly four times to 32 GL/year under the 2040 full urban land use with high climate chang...

Data are presented in two spreadsheets: laboratory-scale testing data and pilot plant trial data. The laboratory data spreadsheet records the effect of temperature and contact time, water type (treatment pond), and organism strains (laboratory and isolates from wastewater). Target pathogens are E.coli, enterococci, FRNA bacteriophage, cryptosporidium, giardia, adenovirus, coxsackievirus and ascaris. Log Reduction Values (LRVs) are reported. The test water’s pH, turbidity, ammonia concentration, nitrate and nitrite concentration, phosphate concentration, total Kjeldahl nitrogen (TKN), dissolved organic carbon (DOC), total organic carbon (TOC), biological oxygen demand (BOD), chemical oxygen demand (COD), electrical conductivity (EC), total dissolved solids (TDS), suspended solids (SS) and volatile suspended solids (VSS) were recorded. The pilot plant trial data spreadsheet records temperature, flow rates and contact time during MS2 challenge tests. MS2 coliphage and native E.coli concentrations are recorded. LRVs are reported. The test water’s pH, turbidity, EC, soluble calcium, COD, TOC, SS, VSS, and ultraviolet transmittance (UVT) on the challenge test days were also recorded. The pilot plant trial was conducted at Melbourne's Eastern Treatment Plant. The following were project partners: Judy Blackbeard (Melbourne Water), Paul Monis (AWQC, South Australia Water), Andrew Salveson (Carollo Engineers USA), Greg Ryan (Pasteurization Technology Group), and Glen Miller (WJP Solutions)

The relative heat sensitivity of key bacterial, viral, protozoan and helminth wastewater organisms (Escherichia coli, Enterococcus, FRNA bacteriophage, adenovirus, coxsackievirus, Cryptosporidium, and Ascaris) were determined by laboratory scale tests. The FRNA phage were found to be the most heat resistant, followed by enterococci and E. coli. Pilot scale challenge testing of a 2 ML/day pasteurisation pilot plant using unfiltered municipal wastewater and male specific coliphage (MS2) phage showed that temperatures between 69 °C and 75 °C achieved log reductions values between 0.9 ± 0.1 and 5.0 ± 0.5 respectively in the contact chamber. Fouling of the heat exchangers during operation using unfiltered secondary treated effluent was found to increase the energy consumption of t...

The review assesses key variables such as: source water quality, available technology, operability, maintainability, cost, health risks for non-compliance, performance and reliability – and summarise the findings for easy comparison.

This desktop study focuses on the cost and GHG emissions associated with food waste diversion from landfills using aerobic digesters with liquid outputs (ADLO). Despite the emerging popularity of ADLO units for food waste disposal, their cost and the GHG emissions associated with their use have not been independently quantified and compared to those of other food waste management options. This study compared landfill disposals, the currently available composting services, electric food dehydrators, and in-sink waste disposal units (garbage grinders). For a food waste production rate of 30 kg d−1, the landfill base case showed the lowest cost at USD 23 week−1. The modeled ADLO cost ranged from USD 20–42 week−1, depending on performance. Dehydrator costs were high at USD 29 week−1, largely due to the high energy intensity of the process. The cost of the current centralized composting wa...

Silica scaling in reverse osmosis of groundwater is a significant issue in water stressed areas d... more Silica scaling in reverse osmosis of groundwater is a significant issue in water stressed areas due to the limitations that scaling imposes on water recovery. While calcium and magnesium scaling potential can be significantly reduced by the use of ion exchange or other softening processes, the silica scaling potential typically remains. Improving the recovery of reverse osmosis by limiting the potential for silica scale is important in ensuring maximum water recovery. This is particularly important for mining and natural gas industries that are located in remote regions. The remote nature of these sites imposes three major restrictions on the silica scale mitigation process. Firstly, the generation of poorly dewaterable sludges must be avoided. Also, the quality of any reverse osmosis (RO) permeate must be able to meet the end use requirements, particularly for boilers. Finally, silica removal should not impact upon other potentially useful or valuable components within the brine, and should not make the disposal of the unusable waste brine components more difficult. Reduction of scaling potential can be achieved in three main ways: operating RO at high pH after hardness has been removed, operating at low pH, and reducing the silica concentration either in pretreatment or by using an interstage technique. Operating at high pH has the initial requirement of hardness removal to prevent scaling and this could be an issue on some sites. Hardness removal operations that use ion exchange resins may be challenged by water chemistry and the operational costs associated with high chemical regeneration costs. Operating at low pH may be more desirable than high pH operation as this can help to reduce the risk of scale formation from calcium or magnesium salts. The drawback comes from the cost of acid, particularly for high-alkalinity waters. There are numerous silica removal techniques including chemical dosing of lime, or aluminium or iron salts, electrocoagulation, adsorption, ion exchange and seeded precipitation. Of these, adsorption onto aluminium compounds appears to give the best results and have received the most attention where restrictions on sludge production and brine disposal common to operations in remote locations are in place. Adsorption onto iron compounds appears to occur more quickly, but leads to the formation of a hard, glass-like scale that may be more difficult to remove, making this process unattractive from the point of view of sorbent regeneration.

The study so far has focused on wastewater treatment, investigating state-of-the-art knowledge internationally, but has also identified important findings from a case study in Kinglake West, Victoria. While septic tanks are a common form of decentralised treatment plant, there is a drive towards more complex aerobic treatment, coupled with source separation. While aerobic treatment may be more environmentallysustainable, due to decreased fugitive emissions, the energy consumption may be a concern where the associated costs are borne by homeowners. This becomes a particular issue as periods of powering down can result in a significant loss of reliability for the treatment.
