****年,OriginClear利用其特有的专利技术,成功开发了高级氧化工艺AOx,实现了具有突破性意义水净化系统Electro Water Separation(EWS)的进一步补充。
实验室测试表明,EWS与AOx相结合可以解决溶解污染物祛除难题,而在以往的操作中,如果不使用则含氯等的化学物质,难以获得满意的处理效果。
AOx技术代表了目前已知高级氧化工艺发展的最高水平,AOx反应器模块专门设计,用于生成臭氧、过氧化氢和羟基等活性氧(ROS),在不使用化学添加剂的情况下实现污水净化。
AOx反应器
进入AOx反应器的水基本上不含悬浮颗粒和油,在EWS阶段,经过处理的水获得消毒和净化氧化,主要通过活性氧物种(ROS)完成。
在AOx反应器中,水与反应器内的阳极表面反应,原位生成大量ROS。在反应器的阴极,特殊材料靶向选择并触发阴极表面发生其他互补反应,解决不能被氧化的污染物。
在此阶段,少量剩余的微米级悬浮颗粒以及溶解/混溶的污染物将被氧化或还原。在这些化学反应之后,产物将沉降富集在AOx罐的底部以便移除,或者变为废气排出。如果需要,可以对反应器进行洗涤和其他处理。
根据具体的应用要求,AOx可以采用管状或罐状在线高级氧化反应器,或两者结合,这些都采用了OriginClear的专利反应器设计,应用性能可靠。
此外,AOx还可以根据应用需求生成其他化合物,包括氯等,以中和特定种类的污染物(如氨)。
百尺竿头 更进一步
****年*月**日,OriginClear宣布已完成新型污水处理技术AOxPlus的开发和测试, AOxPlus利用该公司特有的专利技术,能够生成大量羟基自由基实现高污染废水的大批量处理。
众所周知,高活性羟基自由基的氧化或清洁能力是氯的两倍以上,而且不产生有毒副产物。根据实验室测试结果,OriginClear工程师预计新的AOxPlus系统可以产生比上一代AOx技术多*****倍的羟基自由基,在相同的设备上提供更为卓越的污染物分解能力。
为了提高羟基自由基生成水平,OriginClear研究团队在一个新反应器中使用了一种特殊的吸气膜,可以分解难以去除的污染物。AOxPlus不需要注入化学添加剂或清水,与采用金刚石电极的技术相比,AOxPlus的经济效益明显更高。AOxPlus的出现解决了诸多行业的废水污染问题,可以为废水排量大的行业提供更有效的处理解决方案,例如油气开采。
今年*月,******Carollo Engineers对AOx模块进行了应用审查,并提交了一份测试结果报告,目前该报告的摘要已经公布。该研究量化了AOx模块有效生成氯基氧化剂的能力。还证实了AOx技术产生的羟基自由基可以处理高度污染的水,如垃圾渗滤液或工业废水,新一代AOxPlus的进步主要建立在这种既定能力的基础上。
OriginClear Technologies总裁Jean-Louis Kindler说:“通过AOxPlus这个新模块,我们就可以在彻底告别强化学添加剂的情况下提高氧化能力,这项新技术适用于工业环境,并且成本效益非常高。”
OriginClear的技术团队目前正在洛杉矶Kretz创新园区的高级原型制作中心制造生产AOxPlus装置。目前,第一台AOxPlus设备已经运往OriginClear******,将在亚洲进行定期示范。第二台设备将交付于佛罗里达大西洋大学(FAU),OriginClear于****年*月与其合作,主要研究垃圾填埋场“黑水”或渗滤液处理方面的技术。
FAU环境与地球工程系副主席Dan Meeroff博士说:“在我们与OriginClear的项目中,目前我们已经测量证实了AOx模块在垃圾渗滤液中去除氨和COD的良好性能。我们正在考虑使用Fenton工艺去除水中残留高硬COD,并期待OriginClear的AOxPlus技术成功推广,并将其用作废水的最终处理手段。”In ****, OriginClear announced that it successfully developed and proved its proprietary Advanced Oxidation process, AOx, to complement its breakthrough water cleanup system, Electro Water Separation?, or EWS.
University laboratory tests have shown that EWS, combined with Advanced Oxidation (EWS:AOx), can now also address dissolved contaminants, which are otherwise difficult to remove without chemicals such as chlorine.
AOx technology is an evolution of known Advanced Oxidation processes.The AOx reactor module is specifically designed to focus on the generation of Reactive Oxygen Species (ROS) such as ozone, hydrogen peroxide and hydroxyls.
The AOx reactor takes water that is largely clear of suspended solids and oils. In the EWS stage, this water has begun to acquire disinfecting and decontaminating oxidants, known as Reactive Oxygen Species or ROS.
In the AOx reactor, reaction with the anode surface inside the reactor causes on-site generation of an additional large amount of ROS. Targeted cathode material selection triggers other complementary reactions occurring at the cathode surface, addressing contaminants that cannot be oxidized.
At this stage, the few remaining fine micron-sized suspended solids as well as the dissolved or miscible contaminants will be oxidized or reduced. The resulting elements after these chemical reactions will either precipitate and sink to the bottom of the AOx tank for removal, or dissipate as offgas that can be scrubbed and treated if needed.
Depending on the application requirements, AOx can be implemented in tube-shaped inline Advanced Oxidation Reactors or in an Advanced Oxidation tank – or in combination – both featuring OriginClear’s patented reactor designs.
AOx can also generate other compounds including chlorine, to neutralize specific contaminants such as ammonia.
Los Angeles, CA – September **, **** – OriginClear Inc. (OTC/QB: OCLN), a leading provider of water treatment solutions, announced today that the company has completed development and testing of AOxPlus, a patent-pending method to produce hydroxyl radicals in large quantities to treat highly-contaminated wastewater.
The highly-reactive hydroxyl radical delivers more than twice the oxidation, or cleansing power, of chlorine, without the toxic byproducts. Based on laboratory testing, OriginClear engineers estimate that the new AOxPlus can produce **,*** times more hydroxyl radicals than the original AOx technology, delivering superior contaminant breakdown on the same footprint.
To generate these new levels of hydroxyl, the OriginClear research team used a special air-breathing membrane in a new reactor, disintegrating hard-to-remove contaminants. AOxPlus does not require chemical injection, or clear water (as with Ultra-Violet or UV), and is cost-effective when compared with, for example, diamond electrodes. It can offer a more efficient treatment solution to sectors that produce highly-contaminated wastewater, such as the pharmaceutical and food industries.
In April, the national engineering firm Carollo Engineers conducted a review of the AOx module, and submitted a report, with a summary now available. The study quantified the AOx module’s ability to generate chlorine-based oxidants efficiently.
It also confirmed that AOx technology produces hydroxyl radicals that can treat highly contaminated waters such as landfill leachate or industrial effluents. AOxPlus further builds on this established capability.
“With this new module, AOxPlus, we can increase oxidation power without relying on the addition of strong chemicals or other additives”, said Jean-Louis “JL” Kindler, president of OriginClear Technologies. “This new technology is practical for use in industrial environments, and cost-effective to implement.”
OriginClear’s Technologies team is currently manufacturing pre-commercial AOxPlus units in the Advanced Prototyping Center at the La Kretz Innovation Campus in Los Angeles. A first unit has been shipped to OriginClear’s wholly-owned subsidiary in China for scheduled demonstrations in Asia. A second unit is intended for Florida Atlantic University (FAU), with which OriginClear partnered in April **** to study OriginClear’s technologies in landfill “black water” or leachate treatment.
Dr. Dan Meeroff, associate chair and professor at FAU’s Department of Civil, Environmental & Geomatics Engineering, said, “In our current project with OriginClear, we have already measured good performance of the AOx module for ammonia and COD removal in landfill leachate. We are considering using a Fenton process to remove the remaining harder COD in that water and are looking forward to receiving the AOxPlus prototype from OriginClear and using it as the final polishing stage.”
OriginClear filed a provisional patent with the United States Patent and Trademark Office (USPTO) on August *th, **** to protect the Intellectual Property related to the manufacturing methods and the process for using AOxPlus.
OriginClear’s core technology is Electro Water Separation (EWS), which efficiently clarifies water by removing visible solids and oils. In ****, the company developed and proved its proprietary Advanced oxidation process, AOx, to address dissolved contaminants. EWS and AOx can be used separately or in synergy.
