Smart membranes for treatment of produced water

G2 O Water Technologies Limited成立于2015年，提供石墨烯膜涂层，可显著降低水处理的成本和环境影响。G2 O公司位于英国达雷斯伯里科技园，拥有一个先进的实验室，拥有广泛的膜设计、开发和测试能力。该项目建立在以前的iUK资助项目的基础上（项目编号102538 -智能过滤器），为石油行业提供变革性的过滤解决方案，将大大降低石油生产的成本和环境影响。在开采原油的过程中，每桶石油会产生3桶污染废水（约100吨）。每年12万亿升）。采出水必须经过净化后才能回注井内、排入当地地下水位或用于其他工艺。目前的净化方法是能源密集型的，耗时的，并使用大量的危险化学品。膜过滤系统有可能解决这些问题。然而，目前的膜通常不适合从水中去除油，快速结垢并且迅速变得完全无效，因此没有被广泛使用。G2 O受专利保护的技术有能力改变这一点，使膜过滤得以利用，在之前的iUK资助项目中，结果表明，用G2 O涂层处理的膜在分离油和水混合物方面非常有效，并在整个操作周期中保持最佳性能。降低采出水处理的成本和环境影响。

G2O Water Technologies Limited was established in 2015 to deliver graphene-based membrane coatings that significantly reduce the cost and environmental impact of water treatment. The product applications include desalination, industrial wastewater treatment, processed water treatment and domestic water filtration systems.G2O are based in the UK at the Daresbury Sci-Tech Park, and occupy a state-of-the-art laboratory incorporating extensive capabilities for design, development and testing of membranes.This project builds on a previous iUK funded project (project number 102538 - Smart Filter), delivering a transformational filtration solution for the oil industry that will significantly reduce the cost and environmental impact of oil production. During extraction of crude oil, 3 barrels of contaminated wastewater are produced with every barrel of oil (ca. 12 trillion litres per annum). The Produced Water must be purified before it can be reinjected into the well, discharged into the local water table or utilised for other processes. Current methods of purification are energy intensive, time consuming and use vast quantities of hazardous chemicals. Membrane filtration systems have the potential to resolve these issues. However, current membranes are generally unsuitable for removing oil from water, fouling rapidly and quickly becoming wholly ineffective, so are not widely used. G2O's patent protected technology has the capability to transform this, enabling membrane filtration to be utilised, with results in the previous iUK funded project illustrating membranes treated with G2O coatings are highly effective in separating oil and water mixtures and maintain peak performance throughout the operational cycle.G2O will be working with strategic partners to be bring this transformational technology to market and deliver significant reductions in the cost and environmental impact of Produced Water treatment.
