  • The risky business of resource recovery

    Waste management operations, like any transport business, have many risks attached to them and all operators should avoid the “Dodgy Brothers” ignore-the-risks to save costs approach! Any transport business with large vehicles working in tight city and site access areas is prone to accidents and near miss incidents. Add to that the hazards of working with lifting, loading and compacting systems. ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Pilot test of pollution control and metal resource recovery for acid mine drainage

    The study was undertaken in order to recover the metal resources from acid mine drainage (AMD). A 300 m3/d continuous system was designed and fractional precipitation technology employed for the main metals Fe, Cu, Zn, and Mn recovery. The system was operated for six months using actual AMD in situ. The chemicals' input and also the retention time was optimized. Furthermore, the ...

  • A novel PSB-EDI system for high ammonia wastewater treatment, biomass production and nitrogen resource recovery: PSB system

    A novel process coupling photosynthetic bacteria (PSB) with electrodeionization (EDI) treatment was proposed to treat high ammonia wastewater and recover bio-resources and nitrogen. The first stage (PSB treatment) was used to degrade organic pollutants and accumulate biomass, while the second stage (EDI) was for nitrogen removal and recovery. The first stage was the focus in this study. The ...

  • Produced water recovery at Seneca Resources using short bed ion exchange

    As a result of water restrictions in the Bakersfield, California area Seneca Resources has installed a new produced water recovery system. The paper reviews this process, which consists of water knock out and clarification tanks, an IGF unit, a specialized nutshell filter, and a short bed ion exchange softener that is regenerated with salt. The water being treated has a TDS level of 4,000 - ...

  • 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 ...

  • A model and a simulator for disaster recovery

    The level of economic and social cost arising from large scale disasters has become apparent in recent years. One of the conclusions that can be drawn from recent experiences is that both corporations and regulators have difficulty in predicting both the post disaster scenario, and the results of management actions in these scenarios. This paper discusses an approach that could lead to ...

  • Heat recovery from wastewater

    Heat recovery from gray water is particularly important in water-intensive industries such as pulp and paper plants, dairies and breweries. Rather than flushing used water down the drain, consider whether a heat exchanging system can help you put that energy to work in your process again. Most plant operators arc aware of the need to save money and reduce the environmental impact of their plant ...

  • Paper and Cardboard - Recovery or Disposal?

    To provide a solid basis for policies and policymakingin the field of waste management, the environmental and economic impacts causedby different waste treatment options should be examined. In recent years, a large number of studies comparing recycling with recovery or final disposal have been published, which are based on life cycle assessment (LCA) and cost-benefit analysis (CBA). To the ...

  • Environmental evaluation of systems for the recovery of biogenic wastes

    The recovery of waste materials is promoted by the German Waste Act 'Kreislaufwirtschafts- und Abfallgesetz'. It requires that among the recovery routes available for a specific waste category the priority has to be on those which are more environmentally compatible. As a restriction given by the law, only those recovery routes which are technically feasible and economically reasonable must be ...

  • Planning for disaster recovery

    Q: When is a business disaster not a complete disaster? A: When you have a disaster recovery system in place, of course. The dictionary defines disaster as “an occurrence that causes great distress or destruction”. Any business can be affected by natural disasters, like recent weather patterns, contrived disasters such as the credit crunch, or even physical disasters like the loss of your ...

  • Waste water recovery

    Wastewater Treatment Recovery and Recycling Supports the Environment. Industrial Waste Water Treatment has encompassed industrial waste water recovery and recycling for a long time now, and it's getting better and better.No longer do wastewater producing industries nonchalantly discharge wastewater into runoff systems that eventually merge with the water cycle whether in lakes, streams or in the ...

  • Feasibility of anaerobic membrane bioreactors (AnMBR) for onsite sanitation and resource recovery (nutrients, energy and water) in urban slums

    Slums are challenging locations for sanitation technologies. High population densities, a lack of water and electricity infrastructure, and space constraints combine to ensure that many traditional waste treatment technologies fail when implemented in this context. This paper proposes the use of anaerobic membrane bioreactors (AnMBRs) for slum sanitation. AnMBRs allow for localized water ...

  • Treatment of Biogas Produced in Anaerobic Reactors for Domestic Wastewater: Odor Control and Energy/Resource Recovery

    Anaerobic municipal wastewater treatment in developing countries has important potential applications considering their huge lack of sanitation infrastructure and their advantageous climatic conditions. At present, among the obstacles that this technology encounters, odor control and biogas utilization or disposal should be properly addressed. In fact, in most of small and medium size anaerobic ...

  • Evaluation of resource recovery through a Waste-to-Energy plant operating with municipal solid waste

    On 1 December 1984, an inter-local joint enterprise agreement was entered into between the Alexandria Sanitation Authority and the Arlington Solid Waste Authority (the 'Authorities'). The Joint Enterprise was formed to design, construct, equip, test and operate a solid waste to energy facility having an installed capacity of 975 tons per day of mixed Municipal Solid Waste (MSW). ...

  • 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 ...
