AD is used by 146 UK WT plants to clean wastewater and produce energy but its efficiency isseverely limited by aggressive scale in pipes and equipment. AD suffers from aggressivescaling in pipes and equipment as the wastewater must be heated to facilitate AD. Scalereduces heat exchange, reducing efficiency of AD and consequently reducing methaneproduction by up to 25%, losing water companies an avg of £490K annually for each ADfacility.Existing de-scaling solutions are chemical & mechanical treatments. These are expensive anddamage surfaces, resulting in rapid re-scaling and ongoing expense. Descaling chemicals killAD bacteria so facilities must be shutdown for descaling.WT companies use polymer to thicken wastewater (referred to as sludge once majority ofwater is removed) before transportation to sewage treatment centres, however thisthickening/dewatering can be very inefficient, resulting in increased weight of sludge beingtransported. Water companies spend on avg £1.5m per treatment centre per yr on sludgetransport.Project will output Paradox, a non-chemical method for treating wastewater using frequencymodulatedenergy to change the properties of wastewater, causing coagulation of suspendedsolids. Paradox will: 1) Remove existing scale build up and eliminate ongoing scale (Calcite,Struvite, Vivianite). 2) Significantly improving separation, reducing polymer consumption by25%. 3) Enhance effect of coagulants, reducing chemical consumption, reducing cost. 4)Reduce equipment damage and maintenance required. 5) Increase efficiency of the AD plantby 10%. 6) Reduce sludge water content by 20%, reducing transport costs by £300K pertreatment facility per yr.UK market for Paradox (spending on polymer/coagulants, descaling chemicals and sludgetransport) is worth £66m in 2013, growing 10% CAGR to £124m by 2020.

AD被146家英国WT工厂用于清洁废水和生产能源，但其效率受到管道和设备的严重限制。由于必须加热废水以促进AD，因此AD在管道和设备中遭受侵蚀性结垢。水垢减少了热交换，降低了AD的效率，从而使甲烷产量减少了25%，每年每个AD设施给水务公司造成的损失平均为49万英镑。现有的除垢解决方案是化学和机械处理。这些都是昂贵的和损坏的表面，导致快速重新缩放和持续的费用。除鳞化学品会杀死细菌，因此必须关闭设施进行除鳞。WT公司在将废水输送到污水处理中心之前，使用聚合物对废水（去除大部分水分后称为污泥）进行增稠/脱水，但这种增稠/脱水效率非常低，导致输送的污泥重量增加。自来水公司每年在每个处理中心的污泥运输上平均花费150万英镑。该项目将输出Parkway，这是一种非化学方法，用于处理废水，使用调频能量来改变废水的性质，引起悬浮固体的凝结。Paramount将：1）清除现有的结垢，并消除正在形成的结垢（方解石、鸟粪石、Vivianite）。2)显著改善分离性能，降低聚合物消耗25%。3)提高混凝剂的效果，减少药剂消耗，降低成本。4)减少设备损坏和所需的维护。5)AD工厂的效率提高10%。6)减少20%的污泥含水量，每年每个处理设施减少30万英镑的运输成本。2013年，英国的Parkless市场（用于聚合物/混凝剂、絮凝化学品和污泥运输的支出）价值6600万英镑，到2020年，复合年增长率为10%，达到1.24亿英镑。
