Meet 'Barrel’ - the new face of digital desalination?

使用数据优化工厂性能

A new modular technology combining multiple reverse osmosis (RO) membranes with digital sensors is hoping to shake up the desalination market.

称为桶,钢压容器含有可以通过智能互连系统远程监测的膜元件。

虽然膜基解,installation of the Barrel is inspired by large evaporators of thermal desalination plants, according to Veolia Sidem, the company behind the development.

With the option for the Barrel to be built off-site and then delivered as a plug & play option, it’s hoped this will reduce capital costs, as well as offering a smaller footprint.

目前在演示阶段,一个小规模桶系统,包括七个压力容器,已经运作从加勒比海处理海水。

第二个安装,以略大的49个压力容器等级,是由于安装在公司现有的阿曼苏尔州现有的海水淡化厂,160公里的马斯喀特西南。

Smart connectors: Creating a digital barrel

The interconnector system includes electrodes that can provide real-time data on temperature and salinity.

Smart interconnectors are installed within the permeate tube, next to standard interconnectors, while loading the membranes. This gives a “permanent vision of the condition of each membrane” to help with diagnosis, operation recommendations, maintenance strategies and scheduling.

The concept is that based on this data, plant operators can optimise plant performance continually, leading to lower operation costs.

Veolia Sidem believes that by reducing the number of high-pressure connections, it will “drastically reduce” leakage sources found on the multiple high-pressure connections of traditional RO skids.

该公司正在将桶装作为一种数字解决方案,它与Aquavista数字平台开发结婚。

那么这项工作将如何?

互连装置可以与模塑在树脂结构中的天线连通,并提供具有局部电导率和温度的分布式控制系统(DCS)。根据该公司的说法,在DCS的几分钟内,桶渗透网络的完整映射可用。

连续监测RO膜的工作温度以确保满足膜供应商的建议。

Commenting as part of abroader article在IDA世界国会上,在GWI的出版商发布的系统推出,克里斯托弗卡森表示,桶发展可能“改变未来海水淡化”.

He said: “The concept was put together by a few old thermal desalters. Facing the choice of either becoming world-beating membrane specialists or being sent home to tinker with their kettles for the rest of their lives, they have come up with something quite brilliant….it is a challenge to every other player wishing to stay in the large plants market.”

Reduced flexibility

Dr Graeme Pearce, a membrane technology specialist with 30 years of experience in membranes, believes the upfront cost of the Barrel will be more but could be outweighed by design savings.

“The barrel vessel will be expensive, but there will be a saving on the number of vessels which will compensate,” he said. “The flexibility of the system will be much reduced, so it probably only makes sense for large or very large plants.”

谈到Aquatech Global活动,员工咨询公司的校长也谨慎地持谨慎态度影响该技术。

“Avoiding the building would probably be a pipe dream,” he said. “This has been claimed before but never works out. The degradation of materials in the merciless heat and UV is highly damaging to all sorts of plastics. Seawater reverse osmosis (SWRO) plants in the Middle East deteriorate very rapidly in buildings, so this would be much worse with additional decay factors if outside.”

“总之,它可能是一个有趣的发展,可以减少竞争激烈的市场中的成本,因此我们应该留意它。对我来说,对我的好处是不明智的。很好的想法是可能的,但它们会储蓄和改进吗?“

Pearce博士得出结论认为,下一阶段是了解“对比较经济学的实际招标案例研究,然后是一个操作案例研究,以了解福利是可实现的。

Responding to desalination market challenges and conditions

So have been the key drivers behind this development?

In its recent 'Wave' magazine, Veolia Water Technologies said the current desalination market “continues to display significant challenges”.

Veolia说,中东地区脱盐水的全部市场价格从未如此低于0.5美元的淡水,从未如此低。

It added that number and size of new desalination projects put the equipment supply industry under enormous pressure to deliver within time and budget.

“The competition is as fierce as ever on this market,” said Vincent Baujat, managing director of SIDEM. “In these challenging market conditions, competing actors struggle to save resources necessary for research and development budgets on new technologies.”
