  • Alternative water supply and treatment solutions in Durban (SA)

    As a result of persistent drought conditions in South Africa a customer (an international consumer goods producer with a production facility in Durban) experiences the pressure of limited availability of water. The ever dropping dam levels currently result in higher risk for intermittent water supply resulting in unplanned and forced production stops in case no water is available. Aquest Colsen ...

  • Techniques for Soot in Oil Analysis

    Since no engine is 100% efficient, products other than carbon dioxide and water will be formed during combustion. One such product produced from incomplete combustion is soot. Soot is a mass of mainly carbon particles that are typically spherical in shape. As soot levels rise, the soot particles begin to clump together and ...

  • Monitoring the fate of fluorescing substances recycled in ultrafiltration process backwash water

    The fate of fluorescing substances during the recycling of membrane backwash water (MBWW) ahead of coagulation, flocculation and sedimentation (CFS) with ultrafiltration (UF) membranes has been investigated. Bench-scale UF membranes were used to generate MBWW from a CFS-treated surface water containing 21 mg/L dissolved organic carbon (DOC) registering a 0.95 cm–1 UV254 absorbance that ...

  • Techniques for Oil in Water Analysis

    The people responsible for conducting oil in water measurements understand that the measurement can be quite challenging. Wastewater from different sources can contain many different types of hydrocarbons, each with different chemical make-ups. On top of the lack of chemical uniformity in different oils, there has been a ...

  • Case Study - 30MW Single Flash Power Plant and 20 MW Expansion

    Lihir Island, Papua New Guinea – 2005 In December 2003, Lihir Management Company awarded GDA a contract for supply and site supervision for a 30MW (net) geothermal power plant. In 2005, Lihir contracted with GDA for an additional 20 MW of plant equipment. The picture at the right shows the main power house and annex under construction. The power house is the larger open section which ...

  • Disinfection By-Products (DBP) Precursor Monitoring

    Chlorine has long been used as a primary disinfection method for many water and wastewater treatment applications. However, there is growing concern about the harmful DBP’s produced by the use of chlorine. DBP’s, such as triahalomethanes (THMs), can occur when the natural organic matter (NOM) that is present in the water is combined with chlorine. More specifically, the portion of ...

  • Produced Water Case Study

    Challenge Managing the increasing volumes of produced water associated with oil & gas production as well as sourcing water for operations is becoming more challenging for E&P companies. Handling oily wastewaters with high and variable contents of O&G and TSS requires complex and costly treatment trains with conventional technologies. To evaluate akvoFloat ’s ...

  • Removal of Ni(II) and Cu(II) from aqueous solutions using ‘green’ zero-valent iron nanoparticles produced by oak and mulberry leaf extracts

    The production of zero-valent iron nanoparticles, using extracts from natural products, represents a green and environmentally friendly method. Synthesis of ‘green’ zero-valent nanoparticles (nZVI) using oak and mulberry leaf extracts (OL-nZVI and ML-nZVI) proved to be a promising approach for Ni(II) and Cu(II) removal from aqueous solutions. Characterization of the produced green nZVI ...

  • Identification and assessment of water quality risks associated with sludge supernatant recycling in the presence of cyanobacteria

    This study focussed on the fate of cyanobacteria cells and associated metabolites during the sludge management processes that follow the conventional drinking water treatment train. The topic is of importance, as the release of metabolites during sludge treatment may pose a risk to water quality if supernatant is recycled to the head of the plant. The study of the kinetics of cell damage and ...

  • Failing arsenic mitigation technology in rural Bangladesh: explaining stagnation in niche formation of the Sono filter

    Arsenic contamination of shallow hand pump tube well drinking water in Bangladesh has created opportunities for radical innovations to emerge. One such innovation is the household Sono filter, designed to remove arsenic from water supplies. Applying a strategic niche management approach, and based on interviews, focus groups and a workshop, this article explains the Sono filter's failure to ...

  • Relations between abundance of potential geosmin- and 2-MIB-producing organisms and concentrations of these compounds in water from three Australian reservoirs

    Relationships between the abundance of potential geosmin- and 2-methylisoborneol-producing (2-MIB) cyanobacteria and bacteria, and concentrations of the two taste and odour compounds (T&Os) were examined in a 7 day incubation of natural water from the surface and bottom of three reservoirs in southeast Queensland, Australia. Only a single known T&O-producing cyanobacterium ...

  • Detailed characterisation of essential oils by flow-modulated GC×GC and Tandem Ionisation mass spectrometry

    Volatile oils of plants, also known as essential oils, have been used for many years for their flavour, fragrance and medicinal properties. However, their extreme complexity and diversity presents analysts with a significant challenge when it comes to quality control. They are generally composed of monoterpenes and sesquiterpenes, as well as their oxygenated derivatives, such as aliphatic ...

  • Development and evaluation of a small scale water disinfection system

    Provision of microbiologically safe drinking water for people living in the rural areas of developing countries remains a major challenge to date. A simple gravity-driven membrane point of use system was developed based on woven fabric microfiltration (WFMF) membranes. The WFMF is a loose type of membrane (0.45 μm). However, complete disinfection is not achieved with the WFMF, hence it was ...

  • Water Reuse Terminology

    All water on Earth is used and reused, over and over, in an elegant water cycle. Water reuse occurs in various ways on a daily basis. It happens when a community’s treated wastewater is discharged into rivers or other water bodies. If you live in a community downstream of another, chances are you are reusing water from an upstream town. Scientifically proven advances in water technology ...

  • Removal of naphthalene from offshore produced water through immobilized nano-TiO2 aided photo-oxidation

    In order to increase the applicability of photocatalysis in treating offshore produced water (OPW), an immobilized catalyst was introduced into the UV irradiation system and its performance on the degradation of organic compounds in OPW was evaluated. Naphthalene was selected as the target pollutant owing to its abundance in produced water and its chemical property as a typical polycyclic ...

  • How is biodiesel produced?

    This article is the first in a series that will take a close look at alternative fuels production and source materials. Over the next several months, we will cover natural gas, propane, ethanol, hydrogen, and fuel cells. This month, we will focus on biodiesel. Methods for creating fuels from renewable biomass feedstocks have been used since the 1800s. Vegetable oils were used in diesel engines ...

  • New indices for reliability assessment of water distribution networks

    This paper presents new indices to evaluate the reliability of water distribution networks (WDNs) usable in the design, planning and management of these networks. Since the pressure-driven analysis (PDA) of WDNs produces more accurate results than the demand-driven analysis, the new indices are proposed based on the PDA. In the proposed measures, nodal pressures, nodal available discharges and ...
