Wastewater from wet flue gas desulfurization (wet FGD) systems and integrated gasification combined cycle (IGCC) plants contains highly soluble salts, e.g., calcium and ammonium chlorides, and certain heavy metal salts, which are not so easy to crystallize by evaporation. Discharge of FGD and IGCC wastewaters is usually regulated due to the presence of relatively small amounts of toxic contaminants, such as heavy metals, selenium, boron, and organics. A discussion covers the conventional treatment methods; water evaporation process; crystallization that occurs in the forced-circulation evaporator-crystallizer; alternatives for the use of a crystallizer; and HPD's new ZLD process employing the approach used in industrial crystallization of very soluble chloride salts; a unique low-temperature crystallization process known as the CoLD Process (Crystallization of high-solubility salts at low temperature and deep vacuum).

Membrane bioelectrochemical reactors (MBERs) integrate membrane filtration module into microbial fuel cells (MFCs) to achieve silmultaneous wastewater treatment, bioenergy production, and high-quality effluent. Previous MBERs usually have membrane modules as a part of the MFC reactors that creates challenges for membrane cleaning. In this study, an MBER with an external membrane module was investigated through both experiments and mathematical modeling. This MBER produced a current density of 7.1±0.5Am-3 with an anolyte recirculation of 90mLmin-1; reducing the anolyte recirculation rate had a negligible effect on MBER's electrical performance but resulted in a positive energy balance of 0.003±0.002kWhm-3. Periodic backwashing (1min-backwashing/15min-operation) was demonstrated as an effective method for fouling control. A mathematical model was developed and validated using the experimental data. The model could predict the influence of key parameters such as influent organic concentration and anolyte flow rate on the current generation, and identify the maximum organic loading rate for current generation. Those results encourage further investigation and development of this MBER toward system scaling up. © 2015 Elsevier B.V..

Within the current and future world's water scarcity, the reuse of treated waste water for specific applications offers an appealing alternative to conventional fresh water sources that cannot meet the expectations, mostly in terms of quantity. Spain is no exception to this global situation, with a constantly increasing population, in combination with growing water demand for applications such as production industry, exportation oriented agriculture, tourism development, and booming construction, access to sufficient quantities of fresh water is currently a rising concern. Camp de Tarragona (ACA) Water Reclamation Project is a prime example how water scarcity can be solved regionally by reclaiming water that would otherwise be discharged to the sea. The new reclamation plant treats municipal secondary effluent from Tarragona and Salou/Vilaseca Wastewater Treatment Plants to supply process water for the petrochemical industry of Tarragona. The plant capacity is currently 19,000 m3/d (Phase I), and further expansions are planned for increases up to 29,000 m3/d (Phase II) and even to 55,000 m3/d (Phase III) in the coming years. This additional supply would replace the water currently taken from the Ebro River, thus releasing this volume for drinking water supply to the population. Utilizing such a process, the industrial growth in water scarce regions can be supported and industry sustainability is increased further. A pipeline connects the two different Wastewater Treatment Plants (WWTPs), 10 km apart from each other, and feeds secondary treated effluent to the reverse osmosis (RO) pretreatment process. The pretreatment consists of ballasted flocculation, followed by disc filtration, sand filtration, and multimedia filtration prior feeding it to the two pass RO system. Final permeate treatment is done by UV light and chlorine disinfection, prior releasing water to the distribution system. This paper will review the detailed design of the plant, as a scale-up of pilot plant results, as well as the RO membranes performance data obtained during the start-up of the installation. RO performance is evaluated in detail taking into account the performance differences when different combinations of raw water sources were used. This paper will also explain in detail the preservation of the installation by means of 5-Chloro-2-Methyl-2H-Isothiazol-3-one/2-Methyl-2HIsothiazol-3-one (CMIT/MIT), during a medium term stop of the plant. © 2013 Desalination Publications.

The cost of water treatment is now more than ever a major consideration for maintaining an environmentally and economically sustainable mining operation. As an industry, we often have to consider water sources that are highly impure and difficult to treat. We are also discovering the value of our waste waters in this regard and using new and improved methods and technology to reclaim and reuse water. In many instances, the water or waste water to be treated is highly acidic and saturated in sparingly soluble salts. Conventional systems used to liberate this type of water typically involve high doses of lime with large volumes of waste sludge produced, and are comparatively complex to operate, to pretreat the water in order to reduce scaling tendency on the reverse osmosis stage. However, if the water is considered valuable for reuse, then why not avoid difficult and cumbersome pretreatment processes and treat the water at low pH to keep the sparingly soluble salts, metals and other dissolved species in solution. This paper describes a patented technology that uses and successfully proves this concept as a cost effective option for certain situations. Results from a treatability study on an Australian groundwater are discussed, along with an economic comparison to a conventional method and discussion on full-scale potential.

Desalination and Water Treatment | Year: 2013

Deep coastal aquifer of Llobregat delta constitutes the main source of drinking water supply to El Prat de Llobregat municipality (64,000 inhabitants) near Barcelona (Spain). Since 70s this aquifer initiates a gradual salinization process by seawater intrusion, magnified by an exhaustive and not ordered water extraction. Also, aquifer pollution by volatile organic compounds (trichloroethylene and tetrachloroethylene) appeared in 90s. In order to remove groundwater pollution, three air stripping plants were built 15 years ago. When groundwater salinity achieved nondrinking water standards, two water treatment plants (Sagnier WTP and Mas Blau WTP) were built using reverse osmosis technology. Both WTPs by RO has a pre-treatment based in volatile organic compounds removal by air stripping, in-line coagulation (only for oneWTP), multimedia filtration, cartridge filtration and scaling inhibitor dosage. Chlorination and dechlorination is available but it is not used. Each WTP has two RO lines with two stages and 75% recovery design. As energy recovery device, Turbo Charger is working as booster pump between first and second stage. Drinking water quality according to Spanish regulations is achieved using filtered water by-pass blend and postchlorination before distribution tank. Operation and maintenance aspects are monitored using supervisory control and data acquisition register and remote/local control by O&M team of Aigü es del Prat (public company). Water quality (raw water, filtered water, RO feed, permeate, blend, distribution tank and point of use) is monitored daily by Aigü es del Prat laboratory (accredited under ISO 17025) according to drinking water Spanish regulations and municipality health criteria. Since January 2009, Aigü es del Prat produces without interruption the 90% of drinking water of El Prat municipality using RO plants. This paper presents the experience acquired on operation and maintenance, reliability, drinking water quality distributed control, groundwater quality evolution, network changes and public perception. © 2013 Desalination Publications.

Consorci Costa Brava is a public water utility created in 1971 responsible of the management of the water cycle in NE Spain. Reclaimed water is produced in 13 facilities which, over the years, have improved their performance and reliability. Operational protocols, online probes, quality-protection criteria and automatization have been instrumental to increase the safety of water reuse by both reducing the risk of failures in the key processes of the reclamation treatment, and by reducing the likelihood that water of insufficient quality could ever reach the end user. This degree of protection has been achieved after identifying the critical control points (CCPs) and the attention points (APs) of the reclamation treatments and also after establishing threshold safety levels for the essential parameters. Since disinfection is key in reclamation treatments, the main CCPs are linked to that process, either if only one disinfectant is applied or if a combination of two or more are used. Another key CCP is at the secondary effluent level, as raw material for the subsequent processes. APs are points where water quality and/or performance of the treatment can be easily monitored to provide additional information on the reliability of the processes. © IWA Publishing 2013.

Commercial production of olive oil generates four times the amount of waste as it does oil, along with a number of environmental issues. We propose an integrated biorefinery concept for the management of pomace, i.e. solid Olive Mill Waste (OMW), that utilizes supercritical carbon dioxide (SCO2), coupled with a polar co-solvent (Ethanol), for extracting value-added polyphenols and mono/poly-unsaturated fatty acids (MUFA/PUFA), followed by thermochemical (oxidation or pyrolysis) recovery of energy, biofuels and materials. The SCO2 + EtOH extraction recovered 77.6 g of freeze-dried extract per kg of raw OMW, with relatively high concentrations in polyphenols (10.9 g kg-1 of which 60.1% of di-hydroxytyrosol), PUFA (20 g kg-1), MUFA (601 g kg-1) and other valuable compounds, such as squalene (10 g kg-1). All these substances are of extreme interest in pharmaceutical and nutraceutical market, for their antioxidant, anti-cancer, functional, anti-bacterial and nutritional properties. The SCO2 + EtOH flux acted as physical/chemical carrier for over 85% of humidity, leaving the exhaust OMW almost dry, with evident advantages for downstream. Using nonisothermal thermogravimetric analysis, the apparent activation energies required to pyrolyze OMW to produce fuel and biochar ranged from 20 to 140 kJ mol-1 depending on heating ramp rate and temperature regime. BET analysis of unactivated biochars show increased (+25%) mesopore surface areas after SCO2 extractions (up to 500 m2 g-1). A more in-depth view on the proposed biorefinery is needed, to consider the overall energy balance, as well as possible market values of the obtained extract, and evaluate the real feasibility of the proposed concept. © The Royal Society of Chemistry 2015.

A high rate fibre filter was used as a pre-treatment to seawater reverse osmosis (SWRO) to reduce membrane fouling. Seawater was drawn from Chowder Bay where the Sydney Institute of Marine Science, Australia is located. A lab-scale fibre filter with a height of 1000 mm and a diameter of 30 mm was used in conjunction with in-line coagulation. The effect of operating the fibre filter with different packing densities (105, 115 kg/m3) and filtration velocities (40, 60 m/h) was investigated in terms of silt density index (SDI10), modified fouling index (MFI), pressure drop (ΔP), turbidity and molecular weight distribution (MWD). The use of in-line coagulation improved the performance of fibre filter as measured by the MFI and SDI. Regardless of filtration velocity and packing density the MFI and SDI10 values remained low as did the turbidity until the end of the filtration run. The MWD analysis showed the removal efficiencies of organic materials like biopolymers, fulvic acids, low MW acids for even experiments with the highest filtration velocity (60 m/h) and lowest packing density (105 kg/m3). This pre-treatment has a small foot print as it has the capacity of operating at a very high filtration velocity. © 2009 Elsevier B.V. All rights reserved.
