暴水规则要求提高处理水平通常采取过滤系统的形式暴水中两种过滤系统是介质过滤和膜过滤
媒体过滤系统功能通过物理捕捉污染物以及通过化学反应吸附污染物 典型媒体过滤系统由沙石、有机物或其他材料组成
Media filters work in two basic ways. First, stormwater passes over and through the media. Pollutants become trapped in the voids between media particles, as well as on media particle surfaces themselves. The second way in which media filters remove pollutants from stormwater is through chemical reactions and adsorption. Adsorption occurs when a pollutant is removed through chemical or molecular actions. This is known as cation exchange. The cation exchange process is most commonly utilized in media filters targeting nutrient and metal removal. It is important to understand the pollutant removal goals for a project and select the appropriate media gradation and composition to promote successful removal.
薄膜过滤使用薄渗透层或薄片排水消除杂质和目标污染物
膜滤波用各种材料设计制造。 一般说来,材料选取基于两个关键因素:孔尺寸和耐久性。孔尺寸指膜材料中“孔数”或“漏洞数”的大小。孔数越小,粒子阻塞穿过膜滤波时阻塞越小。可达性指膜功能和耐受其接触条件的能力
暴水应用中,关键是膜滤波能承受水、沉积和沙子、金属、养分和油气基材料/物质的影响。 当膜滤波新时,小于孔径大小的粒子会穿透滤波薄膜开始捕捉大于孔状粒子时,它开始抓取 ripen 。 薄膜割裂时,孔状下降并捕捉小粒子 。 薄膜滤波失效时,暴水不再穿透它,或水流流速(流速)小于滤波设计流速
今日暴水规则继续逼迫土地所有者提供暴水溢出处理,并证明为过滤技术提供高层次单机处理、量基处理以及强化预处理绿色解决方案。查查Contech工程解决方案媒体和薄膜过滤解决方案m.digimundi.com/jellyfish并m.digimundi.com/stormfilter.
