  • Material flow analysis of pollutants in Taiwan

    We present a material flow analysis (MFA) of biological oxygen demand (BOD5) and suspended solids (SS) in estuaries located on the northern and southern coasts of Taiwan. Using data from 1992–2000, we examine human economic activities in each watershed to predict associated pollutant flows. This estimate is compared to data collected at monitoring stations. The ratio allows us to calculate each ...

  • Energy and material management based on a fuzzy-Petri net approach

    In modern production systems, materials and different forms of energy are provided, converted, stored and transported. Environmental impacts can be identified at any stage of the energy and material flow process. Due to the fact that production units and processes are interconnected with energy and material flows, it is of special interest to implement production control policies, which control ...

  • A material flow analysis of wood and paper in Cape Town: is there potential to redirect flows in formal and informal sectors to foster use as a renewable resource?

    The City of Cape Town has recently drafted an energy strategy and an integrated waste management plan. The creative implementation of these strategies requires knowledge of potential sources of energy and flows of waste. Inventories of requisite data are sparse. Wood and paper are interesting cases in point, as they are significant contributors to waste and potential energy carriers. A better ...

  • Assessing material flows in urban systems: an approach to maximize the use of incomplete data sets

    Data scarcity and uncertainty are the main limiting factors for an integral evaluation of the urban water and wastewater management system (WWMS) in developing countries. The present research shows an approach to use incomplete data sets to analyse the flows of water and nitrogen and to make an integral evaluation of the WWMS at a case study city. By means of data validation and model ...

  • Wastewater engineers go with the flow

    The efficiency of maintenance work has been improved by water treatment engineers employing Intellisonde monitors in their final effluent. Designed primarily to measure water quality, the Intellisondes also measure flow, and this reading is being used to detect the accumulation of debris that necessitates a maintenance visit. Wastewater treatment efficiency is often measured by the analysis of ...

  • Material Matters - An Engineering and Fabrication Challenge

    The world of engineering is a very large and diverse universe which ranges from electrial, mechanical and civil to environmentaland structural. It is true that their varied disciplines have many qualities in common, e.g. the mixture of logic, creativity, awareness of cost /benefit ratio etc., are requirements of all engineering. It is equally true that each discipline has its own mind set, ...

  • Predictive water quality modelling and resilience flow conditioning to manage discolouration risk in operational trunk mains

    This paper presents predictive discolouration modelling and subsequent field trial validation for a cast iron trunk main network. This enabled a UK water company to propose an ‘operational flow conditioning’ maintenance plan that reduces discolouration risk, improves network resilience and asset condition and yet does not require the trunk main to be decommissioned for invasive ...
