NEWS they operate at guaranteed maximum recovery rates, reducing wastewater by 50–75% and energy consumption by up to 35%, resulting in a significant saving in operating costs. ‘Many of our customers require the water purity that only reverse osmosis can provide. Desalitech’s high-efficiency reverse osmosis systems are a great addition to our mobile fleet,’ commented Lisa Sorgini Marchewka, who is the vice president of global strategic marketing for Pall’s water group. Desalitech worked with Pall to design a custom trailer-based ReFlex RO system that is compatible with Aria products. The Desalitech unit can produce up to 2650 litres (700 gallons) per minute of RO permeate at water recovery rates of 70–98% from feed water with a salinity up to 10 000 ppm TDS. ‘Desalitech strives to make our customer’s lives easier, whilst saving them considerable amounts of water and money,’ added Nadav Efraty, CEO, Desalitech. ‘Pall’s position as a global leader in water treatment makes it an invaluable partner in our efforts to bring our next-generation RO products to new customers and projects around the world.’ Contacts: Desalitech Ltd, One Gateway Center, Suite 250, Newton, MA 02458, USA.

Desalination plants to double by 2020
A
report, entitled ‘Analysis of Global Desalination Market’, published by Frost & Sullivan reveals that the market earned revenues of $11.66 billion in 2015 and estimates this will reach $19.08 billion in 2019. More than 17 000 desalination plants are in operation in 150 countries worldwide, a capacity that is expected to double by 2020, says the market research company.

Increasing global water scarcity because of rapid industrialisation and urbanisation has opened up vast avenues for growth in the desalination market. As drought situations intensify, desalination will evolve into a longterm solution to such problems rather than a temporary fix. Developing cost-effective and sustainable systems will enable technology providers to capitalise on this immense potential. ‘Environmentally-conscious countries in Europe and the Americas are hesitant to practice desalination owing to its harsh effects on sea water,’ noted Vandhana Ravi, Independent Consultant, Environment and Building Technologies, Frost & Sullivan. ‘Eco-friendly desalination systems that do not use chemicals will be well-received amongst municipalities in these regions.’ Whilst a number of desalination projects are under construction in the USA, India, United Arab Emirates, Saudi Arabia and Mexico, adoption is slow in other droughtstruck portions of the globe, says the study. The lack of regulatory support in several regions limits uptake. Moreover, the desalination process is highly expensive and is prone to contamination. Thermal desalination technology uses large amounts of energy and releases significant volumes of highly salty liquid brine back into water bodies, which massively impacts the environment. Brine disposal will remain a prime challenge until a technology upgrade puts this issue to rest. ‘Carbon nanotubes, radial deionisation and biomimetic aquaporin membranes are some of the new approaches that will push desalination to become an indispensable element in water management,’ added Ravi. ‘Innovations, such as ceramic and polymeric membranes targeted at reducing operating costs will pave the way for the acceptance of desalination as a practical way of tackling the shortfall in fresh water.

Veolia’s technology produces water for Dutch pharmaceuticals firm
A
major pharmaceuticals company – through its appointed engineering partner – recently procured a water treatment system based on sustainable technology for its manufacturing facility in Oss, The Netherlands. The system comprises Veolia Water Technologies’ latest Orion, for purified water, storage and distribution, along with its Polaris VCD technology for production of water for injection, plus full project management. The complete system provided meets the requirements as defined within the US and European treated water guidelines and standards. Project management and execution is ongoing to ensure the required timeline is met to deliver this system in 2016. Orion and Polaris are described as highly competitive, leading-edge Veolia technologies for the production of purified water and water for injection. Both combine tried and tested core processes with the latest innovations in energy and water conservation, as well as key features for health and safety, says the firm. Operational costs are optimised to achieve aggressive payback models for capital investments without compromising long-term reliable operation. Veolia Water Technologies introduced the new Orion system towards the beginning of 2015. It comes with a number of sustainability features, including low-energy reverse osmosis (RO) membranes, integral recovery RO and concentrate recycle. All construction products and materials have been selected for optimum recyclability. As microbial control is paramount in any purified water-treatment system, the Orion retains proven hot water sanitisation (HWS) of the main treatment unit as well as the pretreatment softeners. It is available in three models, with an expanded range of flow-rates – from 0.5 m³/h to 20 m³/h.
