Abstract: In the drinking water industry, pilot plants have played a big role in assisting water professionals, utilities, and engineering firms in generating information about the behavior of large full scale systems. Due to the identification of new contaminants, stringent regulations, and demand for improved water quality the demand for novel water treatment challenges across North America have significantly increased. A portable evaluation pilot skid (PEPS) accommodates all water qualities. A vent valve screen is mounted inside the contactor with holes large enough to prevent clogging. Air is introduced into the contactor prior to the screen. The screen is mounted such that it breaks the air into small bubbles creating the effect of a stone diffusor. Air flow is easily adjusted with a needle valve.

Abstract translation: 在饮用水行业，试点工程在协助水专业人员，公用事业和工程公司生成关于大型全面系统行为的信息方面发挥了重要作用。 由于新污染物的鉴定，严格的法规和对改善水质的需求，北美地区对新的水处理挑战的需求显着增加。 便携式评估飞行员滑行（PEPS）适应所有的水质。 一个排气阀屏幕安装在接触器内部，其孔足够大以防止堵塞。 在屏幕之前将空气引入接触器。 屏幕被安装成使得其将空气分解成小的气泡，产生石头扩散器的作用。 气针可以用针阀轻松调节。
