The UK is part of the Stockholm Convention targeting the removal of persistent organic pollutants (POPs); PFAS and PFOS (poly-fluorinated materials) frequently found in groundwaters and rivers are considered POP chemicals. Companies need to find effective ways to clean both regular water and wastewater from these chemicals by 2030\.Speral Sinfin is a company developing new plasma technology to address within others, water contamination problems. Water is becoming a limited resource and the level of treatment that water requires is increasing every day. The growing presence of Persistent Contaminants is putting a lot of stress on water companies to assure the quality of the water delivered to customers, as well as inflating the cost associated with these treatments. Furthermore, the elimination of grey waters is getting much attention, as the changes in rain cycles are creating temporal high levels of POP.Currently, when eliminating POPs from water, commonly using filtration systems leads the filters to accumulate a highly \[toxic\] concentration of POPs. After the filtration is completed, the filters need to be removed and burnt, which causes a release of a high level of toxic by-products like fluor-based gases into the air (so a system to neutralise these is required); unfortunately, the option of removal and neutralisation by filters is a complex and expensive task. Not many cost-effective alternatives are available today.We propose to eliminate POPs on filtration systems before the filters are removed from the plant. Our proposed plasma treatment is "a chemical treatment, but chemicals free", with no chemicals other than water left behind; plasma-activated water (PAW) means water molecules oxidize the organic material and decompose it returning water to regular, clean condition after a small period of time. PAW can effectively destroy organic material e.g. "eternal chemicals" such as PFOS/PFAS or POP. This technology has some very important benefits: the plasma treatment (directly or PAW) is equivalent to a strong chemical oxidative treatment, but with the advantage that all species are formed locally (no chemicals transportation or manipulation is necessary) and all "chemicals" created by the plasma in water, are short-lived, which means that there is no chemical residue caused by this treatment. All the created waste would be innocuous chemicals (as per scientific publications). This will have an enormous impact in terms of how clean the water treatment can be.

联合王国加入了旨在消除持久性有机污染物的《斯德哥尔摩公约》;地下水和河流中常见的全氟辛烷磺酸和全氟辛烷磺酸（多氟物质）被视为持久性有机污染物化学品。到2030年，公司需要找到有效的方法来清洁常规水和废水中的这些化学物质。Speral Sinfin是一家开发新等离子技术的公司，旨在解决其他人的水污染问题。水正成为一种有限的资源，水所需的处理水平每天都在提高。持久性污染物的不断增加给水务公司带来了很大的压力，以确保交付给客户的水的质量，并增加了与这些处理相关的成本。此外，由于降雨周期的变化造成了持久性有机污染物的暂时高水平，消除灰沃茨也越来越受到关注。目前，在消除水中的持久性有机污染物时，通常使用过滤系统，导致过滤器积累了高[毒性]浓度的持久性有机污染物。过滤完成后，过滤器需要被移除并燃烧，这会导致高水平的有毒副产品（如氟基气体）释放到空气中（因此需要一个系统来中和这些气体）;不幸的是，通过过滤器移除和中和的选择是一项复杂而昂贵的任务。我们建议在滤水器拆除前，先消除滤水系统的持久性有机污染物。我们提出的等离子体处理是“一种化学处理，但不含化学物质”，除了水之外不会留下任何化学物质;等离子体活化水（PAW）意味着水分子氧化有机物质并分解它，使水恢复到正常的清洁状态经过一段时间。PAW可有效地销毁有机物质，例如全氟辛烷磺酸/全氟辛烷磺酸或持久性有机污染物等“永恒的化学品”。等离子体处理（直接或PAW）相当于强化学氧化处理，但优点是所有物种都在局部形成（不需要化学品运输或操作）并且由水中的等离子体产生的所有“化学品”都是短暂的，这意味着这种处理不会产生化学残留物。所有产生的废物将是无害的化学品（根据科学出版物）。这将对水处理的清洁程度产生巨大影响。
