  • Concentration-driven models revisited: towards a unified framework to model settling tanks in water resource recovery facilities

    A new perspective on the modelling of settling behaviour in water resource recovery facilities is introduced. The ultimate goal is to describe in a unified way the processes taking place both in primary settling tanks (PSTs) and secondary settling tanks (SSTs) for a more detailed operation and control. First, experimental evidence is provided, pointing out distributed particle properties (such ...

  • Becoming A “Water Resource Recovery Facility” Offers Financial Benefit

    While the term “Water Resource Recovery Facility” may seem like nothing more than a trendy phrase, the name change represents a distinct shift in the role that wastewater utilities can now play. Wastewater is packed full of resources — nutrients, micronutrients, metals, grit, biopolymers, biosolids, and more — and much of that can be recovered and sold, offering additional ...

  • First implementation of a SEMIZENTRAL resource recovery center

    The SEMIZENTRAL approach has been developed for fast growing cities, to meet their challenges regarding the supply of water and the treatment of biowaste and wastewater. Key elements of the SEMIZENTRAL integrated infrastructure approach are high resource efficiency due to urban water reuse and the usage of the energy potential of wastewater/sludge and waste, as well as its system size between ...

  • Modelling and characterization of primary settlers in view of whole plant and resource recovery modelling

    Characterization and modelling of primary settlers have been neglected pretty much to date. However, whole plant and resource recovery modelling requires primary settler model development, as current models lack detail in describing the dynamics and the diversity of the removal process for different particulate fractions. This paper focuses on the improved modelling and experimental ...

  • Reinvent the toilet: the NUS experience of building a decentralized toilet for energy, water and resource recovery

    In conventional activated sludge (CAS) treatment of sewage, the pollutants are mostly dissipated and hardly any reuse is present. This makes wastewater treatment very energy intensive and not sustainable in the future. Instead, sewage should be considered as a renewable resource, from which value can be extracted in the form of water, energy and nutrients (mostly nitrogen, N, phosphorus, P and ...

  • Power Positive Resource Recovery

    Using laws of thermodynamic analysis to evaluate the energy and power characteristics of wastewater and beneficial uses of biogas offers greater insight into best business practices and what is achievable. Growing numbers of waste-water treatment plants (WWTP) are striving to produce more power onsite. In recent years, there’s even been a race among WWTP operators to see who can ...

  • How Innovation Flourishes within The Nexus?

    The awareness of the conspicuous synergies and antagonisms existing among the various socio-economic sectors that constitute the urban fabric, e.g. water and energy sectors, and the increasingly complex nature of environmental and resource scarcity problems have triggered the discussion on the water-energy-food nexus, referred to as ‘the Nexus’ in this article. The discussion has been ...

  • Towards zero waste, Italy

    In 1993 ThyssenKrupp was looking to improve its internal recycling of by-products. Harsco has a proven record of technology application in the field of resource recovery and production of valuable products form iron and steel making by-products. Harsco’s tailor-made solutions were a natural fit with assisting stainless steelmakers in the recycling materials that have traditionally been land ...

  • Resource recovery from source separated domestic waste(water) streams; full scale results

    A major fraction of nutrients emitted from households are originally present in only 1% of total wastewater volume. New sanitation concepts enable the recovery and reuse of these nutrients from feces and urine. Two possible sanitation concepts are presented, with varying degree of source separation leading to various recovery products. Separate vacuum collection and transport followed by ...

  • Approaches to sustainable manufacturing

    Topics on sustainable manufacturing, use, environmentally friendly treatment and resource recovery are currently very important issues for governments and industries worldwide. Environmental regulations for technical products currently focus on recycling ratios and prohibition of toxic materials. The concept of creating more use-productivity with less resource consumption has considerable ...

  • Plasma resource recovery technology –converting waste to energy and valuable products

    Abstract Plasma Resource Recovery (PRR) is a revolutionary technology that can treat virtually any type of waste by combining gasification with vitrification. Vitrification produces inert slag that can be used as a construction material. Gasification produces a fuel gas containing carbon monoxide (CO) and hydrogen (H2), used for cogeneration of electricity and steam. The plasma fired ...

  • On industrial symbiosis networks and their classification

    The objective of this paper is the classification and characterisation of regional/local industrial symbiosis networks/industrial ecosystems in order to create a framework for future research and to enhance the planning of these systems in practice. Because of inter-organisational cooperation, which is arranged based on spatial proximity between the actors, costs and emissions can be reduced in ...
