Eau, l'Industrie, les Nuisances | Year: 2015

New advances in Green Chemistry have led to the development of novel products for the treatment of industrial waste waters as well as the production of drinking water. After a number of successful proof-of-concept trials there are now an increasing number of full scale applications where Green Technologies are generating value for their users. Amongst these innovations are biosourced coagulants and flocculation adjuvants. It is now clear that in many applications these products can perform as well if not better than traditional synthetic chemicals both in terms of clarified water quality and sludge volume and re-usability.


Managing waste is a challenge for any industry, and one that is becoming ever more difficult year-on-year. For example, the average cost to dispose of trade effluent in the UK has increased by more than 25% over the last 5 years alone. In addition, operational and utility costs continue to go up; the average charges for electricity have risen by more than 30% over the same time period and even the cost of water has also greatly increased. It is widely accepted that these trends are fixed, and that costs will continue increase yearonyear. With this in mind, Veolia have developed several proven solutions to turn waste and wastewaters into renewable energy and/or reusable water, dependant on the industry waste streams and site specific needs.

Polymer Degradation and Stability | Year: 2017

Technology advancements for mixed culture polyhydroxyalkanoate production have been made in recent years at pilot scale, and efforts continue towards implementation of the first commercial scale production facilities. The purpose of the present work was to develop thermogravimetric analysis (TGA) methods for routine monitoring of polymer quantity and quality in PHA-rich activated sludge biomass, and for the recovered polymers. TGA quantification of the biomass PHA content correlated directly with the maximum extractable polymer (±2% gPHA/gTS). Acid pre-treatment of the biomass, prior to sample drying, significantly increased the polymer thermal stability in the biomass. This increase helps to improve the resolution of the PHA fraction of the biomass by TGA. From the TGA results, an extension to common solids analysis from Standard Methods, by including an intermediate volatile solids (IVS) assessment, was developed to quantify biomass PHA content. The IVS method entails sample volatilization and weight loss evaluation at a selected temperature between 200 and 300 °C. This intermediate temperature is in between the Standard Method sample drying (103 °C), and ashing (550 °C) oven incubations, for relative weight loss measurements that are made routinely for solids analysis. Thermogravimetric analyses were applied in isothermal polymer recovery experiments using either acetone or 2-butanol as extraction solvents. Trends in extractability as a function of extraction temperature and time correlated directly to the poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) co-polymer composition in the biomass, over a 3-hydroxyvalerate in PHBV content ranging from 0 to 40 average weight percent, and a polymer weight average molecular mass between 200 and 600 kDa. Polymer type can be used to anticipate the extraction behavior, or conversely, as shown in the present work, isothermal polymer extraction trends can be used to infer the type of polymer present in the biomass. © 2017 Elsevier Ltd

This study investigates the performance of MBBR nitrifying biofilm post carbon removal at high loading and starvation conditions. The nitrifying MBBR, treating carbon removal lagoon effluent, achieved a maximum SARR of 2.13 gN/m2 d with complete conversion of ammonia to nitrate. The results also show the MBBR technology is capable of maintaining a stable biofilm under starvation conditions in systems that nitrify intermittently. The biomass exhibited a higher live fraction of total cells in the high loaded reactors (73–100%) as compared to the reactors operated in starvation condition (26–82%). For both the high loaded and starvation condition, the microbial communities significantly changed with time of operation. The nitrifying community, however, remained steady with the family Nitrosomonadacea as the primary AOBs and Nitrospira as the primary NOB. During starvation conditions, the relative abundance of AOBs decreased and Nitrospira increased corresponding to an NOB/AOB ratio of 5.2–12.1. © 2017 Elsevier Ltd

Biofouling | Year: 2015

The diversity of the bacterial community developed in different stages of two reverse osmosis (RO) water reclamation demonstration plants designed in a wastewater treatment plant (WWTP) in Tarragona (Spain) was characterized by applying 454-pyrosequencing of the 16S rRNA gene. The plants were fed by secondary treated effluent to a conventional pretreatment train prior to the two-pass RO system. Plants differed in the material used in the filtration process, which was sand in one demonstration plant and Scandinavian schists in the second plant. The results showed the presence of a highly diverse and complex community in the biofilms, mainly composed of members of the Betaproteobacteria and Bacteroidetes in all stages, with the presence of some typical wastewater bacteria, suggesting a feed water origin. Community similarities analyses revealed that samples clustered according to filter type, highlighting the critical influence of the biological supporting medium in biofilm community structure. © 2015 Taylor & Francis.

Desalination and Water Treatment | Year: 2016

This study describes the application of closed circuit desalination (CCD) as a first pass for boiler-feed supplies with high recovery (96%) and low energy (0.34 kWh/m3) from a municipal source (553 μS/cm) comprising the scaling constituents Ca (65 ppm), SO4 (180 ppm), SiO2 (32 ppm), F (1.2 ppm), Ba (0.022 ppm), and Sr (0.295 ppm) in addition to modest amounts of Na (65 ppm) and Cl (18.8 ppm). The 96% recovery trials were performed using a pilot comprised of a single module (8″) with three elements (ESPA2-MAX) under fixed flow and variable pressure consecutive sequential CCD conditions at flux of 27.5 lmh and feed temperature of 20.7°C. Under the specified trial conditions, average permeates of 13 μS/cm electric conductivity (~6.5 ppm) are produced with energy consumption of 0.59 kWh/m3 which translates 0.34 kWh/m3 at 25°C and pressurizing means efficiency of 75%. The process proceeds at pH 5.0 in the presence of an antiscalant (Hydrex-4192 and 4102) with recycled concentrates of high super-saturated silica (max. 800 ppm) without any signs of scaling and/or fouling. The module performance results of this study are scalable to larger CCD systems of similar process design. © 2016 Balaban Desalination Publications. All rights reserved.

Abstract: Reverse osmosis (RO) has developed into one of the most commonly applied technologies for the reduction of the salt content of a feed stream. While it is a widely applied purification process, the market is continuously challenging suppliers for innovation to increase the economics and sustainability. This paper will review and analyse the field performance of Dow FILMTEC™ new high-flow/low-energy seawater reverse osmosis elements—SEAMAXX™. This new seawater RO membrane, which has the highest permeability currently available, is based on innovation related to membrane chemistry. SEAMAXX can be used to increase the recovery of an existing system or to decrease the energy consumption. In either case, the final cost of water is estimated to be between 10 and 15% lower compared to previously available state of the art RO elements. This paper will focus on three different cases studies where the expected performance of SEAMAXX has been validated. Two of these cases correspond to small-size and medium-size pilot trials completed at the Water Technology Center of Dow Water and Process Solutions in Tarragona, Spain. The third experience is a commercial installation which has been in operation with SEAMAXX elements since May 2013. In this particular facility, a retrofit of the RO system was undertaken such that existing 11-year-old FILMTEC membranes were replaced with next generation SWRO membranes. This commercial installation, located in the Canary Islands (Spain) treats the seawater (Atlantic Ocean) well to produce drinking water. In this third case, the performance of the desalination plant will be compared with the performance of the previous elements as well as with the predicted or expected performance of SEAMAXX according to ROSA™ (reverse osmosis system analysis) simulation software and DOW™ FT-NORM normalization tool. Rejection of dissolved salts and in particular, rejection of Boron has been carefully monitored by regular analysis in Dow’s R&D Lab and in external certified laboratories. After almost one year in operation, the performance of SEAMAXX has been validated through different seasons and different sets of operating conditions, confirming the expected savings in energy consumption. © 2014 Balaban Desalination Publications.

Viscosity measurements play an important role in activated sludge (AS) characterization, especially with respect to Membrane BioReactor (MBR) operation where low and high shear rates (velocity gradients) occur near the membrane surface and on the bioreactor tank due to the mixing, respectively. Moreover, viscosity plays a role in terms of energy consumption (e.g. pumping and mixing). Therefore, an accurate viscosity relationship as a function of total suspended solids (TSS) and temperature can help to model the behavior of the AS. A total number of 10 municipal and 11 industrial MBR plants throughout Europe were investigated during the period 2007-2009 using the Delft Filtration Characterization method (DFCm). Unlike other literature studies, AS rheology was measured on site, exploiting the resemblance of the DFCm to a tubular rheometer and compared against the results of a rotational rheometer. A new rheological model for the viscosity of AS was developed maintaining the same mathematical structure as previous rheological models made for MBRs. The model proposed in this study is valid for TSS and temperature ranges of 5-20gL-1 and 10-25°C, respectively. This model proves that the DFCm unit can be used as a 'cheap' rheometer and produce the same results as a rotational rheometer for AS viscosity characterization. © 2014 Elsevier Ltd.


A process was developed for biological treatment of municipal wastewater for carbon and nitrogen removal while producing added-value polyhydroxyalkanoates (PHAs). The process comprised steps for pre-denitrification, nitrification and post-denitrification and included integrated fixed-film activated sludge (IFAS) with biofilm carrier media to support nitrification. In a pilot-scale demonstration (500-800L), wastewater treatment performance, in line with European standards, were achieved for total chemical oxygen demand (83% removal) and total nitrogen (80% removal) while producing a biomass that was able to accumulate up to 49% PHA of volatile suspended solids with acetic acid or fermented organic residues as substrates. Robust performance in wastewater treatment and enrichment of PHA-producing biomass was demonstrated under realistic conditions including influent variability during 225days of operation. The IFAS system was found to be advantageous since maintaining nitrification on the biofilm allowed for a relatively low (2days) solids retention time (SRT) for the suspended biomass in the bulk phase. Lower SRT has advantages in higher biomass yield and higher active fraction in the biomass which leads to higher PHA productivity and content. The outcomes show that production of added-value biopolymers may be readily integrated with carbon and nitrogen removal from municipal wastewater.
