The increasing requirement of desalination of sea water due to increasing water demand is driving the global water desalination equipment market at a faster rate. The growth of the water desalination equipment market is subsidized by the increasing concerns over the scarcity water due to rapidly growing population, industrial development and pollution. Also fast improving living standards in the developing regions are demanding cleaner water, subsequently driving the advancements in the desalination technologies. Desalination equipment facilitates desalination process that parts the dissolved salts and other minerals from seawater or other salinized water. The major advantage of desalinised water is that it can deliver high quality water for consumption purpose even at the time of droughts ultimately increasing the overall supply. The emerging water desalination equipment market has been experiencing a phase of new product development and technological advancements due to greater demand. The manufacturing companies are raising their respective market share with increased R&D activities. Some of the major factors subsidizing the growth of water desalination market are increasing rate of technological developments, lack of alternative to the process of desalination, increasing urbanization and rising standard of living of the population. On the other hand the scarcity of fresh water are convincing the government to increase the investment in the enhancement of desalination capacities to meet the water demand. The major restraint in the desalination equipment market is the investment and operation cost involved in the desalination process. Also, with the increasing competition in the market due to new entrants and relatively mature and similar technologies offered by the OEM’s are intensifying the competition and making it price based. Thus the companies’ are needed to grow their organizational efficiency and develop strategic sourcing of components required to manufacture desalination equipment so as to be at a competitive edge. Better management of risk factors and associated costs are required. By application the water desalination equipment market is segmented as follows: By technologies, the water desalination equipment market is segmented as follows: The global water desalination equipmentmarket is expected to register a favourable growth for the forecast period, 2015?2025. Middle-East is projected to endure its control on the global water desalination equipmentmarket followed by North America and Europe. The key countries in the Middle-East are projected to be GCC (Gulf Cooperation Council) and Algeria as an outcome of practicing desalination for long specially in GCC countries. Some of the key players in the desalination equipment market are General Electric, Doosan Heavy Industries and Co, Acciona SA, Genesis Water Technologies, Koch Membrane Systems, Degremont Sas, IDE Technologies, Hyflux Ltd, Biwater, and Cadagua The research report presents a comprehensive assessment of the market and contains thoughtful insights, facts, historical data, and statistically supported and industry-validated market data. It also contains projections using a suitable set of assumptions and methodologies. The research report provides analysis and information according to categories such as market segments, geographies, types, technology and applications.

This article describes the reform of Lines 3 and 4 of Gavà- Viladecans WWTP (Barcelona, Spain) to turn an active sludge conventional purification process into an Hybas hybrid process to eliminate biological organic matter and nitrogen by aerobic zones-anoxic-aerobic-anoxic. The aerobic zones includes a plastic landfill. Moreover, the turbine's aeration has been changed to diffusers with turboboosts. The Hybas treatment design is presented too, together the analytical results obtained during lines start-up.


A continuous supply of oxygen is essential for the correct operation of wastewater treatment plants. The transfer rate of oxygen to liquid medium depends on the design of the aeration system and, mainly, on environmental and operational conditions. The effect of these conditions on the two characteristic parameters of the oxygen transfer rate, volumetric coefficient of oxygen transfer KLa and oxygen saturation of the medium (C*), is dicussed after to analyze the basic principals and the effects of plant design (Tecnología del Agua, no 336 and 338). Moreover, a global correction factor χ is defined as a descriptor of the effect of real conditions on the transfer of oxygen in wastewater treatment systems.

A correct design of the aeration system is essential for technical and economic feasibility of a sewage treatment plant (WWTP), because it involves a 70% of the energy costs of the plant and determine the final degree of purification attainable. In this paper, the basic principles governing the transfer of oxygen gas-liquid are described, together with the main parameters used to define the efficiency of the system.

Extracellular polymeric substances (EPS) have a key role in water treatment processes because they are involved in biosorption, flocculation and adherence processes. In this paper, the main aspects related to the characteristics and chemical composition of the bound and soluble EPS are revised and discussed, together with the effect of operating variables on the production of these substances in the biological wastewater treatment.

A novel design for a pilot scale anaerobic submerged membrane bioreactor (AnSMBR) equipped with an ultrafiltration unit, treating municipal wastewater at 18±2°C, and inoculated with a mesophilic inoculum without acclimation, was implemented and evaluated over 3years of stable operation. The AnSMBR operated with a volumetric loading rate between 1.6 to 2.0kgCOD/m3 UASBd, 12.8 to 14.2h hydraulic retention time, and reached a tCOD removal efficiency of around 90%. Biosolid production was between 0.05 and 0.083gVS/gCODremoved. Dissolved methane oversaturation in the effluent was observed, reaching average values of 19.1±0.84mgCH4/L. The permeate flow rate ranged from 10 to 14L/m2h with trans-membrane pressure (TMP) values of 400-550mbar, using cycles of 30s backwash, 7.5min filtration, and continuous biogas sparging (9-16m/h). During the three years of continuous operation, the membrane was not physically or chemically cleaned. © 2015 Elsevier Ltd.

The performance of a pilot scale anaerobic membrane bioreactor (AnMBR), comprising an upflow anaerobic sludge blanket (UASB) reactor coupled to an external ultrafiltration membrane treating municipal wastewater at 18±2°C, was evaluated over three years of stable operation. The reactor was inoculated with a mesophilic inoculum without acclimation. The AnMBR supported a tCOD removal efficiency of 87±1% at hydraulic retention time (HRT) of 7h, operating at a volumetric loading rate (VLR) of between 2 and 2.5kgtCOD/m3d, reaching effluent tCOD concentrations of 100-120mg/L and BOD5 concentrations of 35-50mgO2/L. Specific methane yield varied from 0.18 to 0.23Nm3CH4/kgCODremoved depending on the recirculation between the membrane module and the UASB reactor. The permeate flow rate, using cycles of 15s backwash, 7.5min filtration, and continuous biogas sparging (40-60m/h), ranged from 10 to 14Lm2/h with trans-membrane pressure (TMP) values of 400-550mbar. © 2015 Elsevier Ltd.
