雨水是地下水蓄水层的重要水源， 无论是直接还是通过采集和再充电。的重要性 净化是为了减少污染物从补给径流的风险 雨水使用砂过滤器作为一种技术被认为是不昂贵的， 通常用于去除水和废水处理中的污染物 行业该方法使用实验室测试，通过设计和 建设中试装置，对砂滤器进行净化试验， 对雨水通过2 米的深度，以找到一个深度之间的关系， 手，并去除悬浮固体和粪大肠菌群的细菌 另一方面，了解得到净化的有效深度。的 三天的入渗研究结果表明，砂滤 可去除150 cm深处的粪大肠菌群， 悬浮固体浓度低于20毫克/升的纯净水 深度为75厘米。
Rain water is an important source to feed the groundwater aquifer, whether directly or by harvesting and recharging. The importance of purification is for reducing the risk of pollutants from recharging runoff rainwater. The use of sand filter as a technique considered not expensive and commonly used for removing contaminants from water and wastewater treatment industries. The methodology used laboratory testing, by designing and constructing pilot plant to experiment the sand filter for purification, and made simulation for the infiltration of storm water through sand filter of 2 meters depth, in order to find the relationship between the depth on one hand, and the removal of suspended solids and fecal coliforms bacteria on the other hand, to know the effective depth that gets the purification. The research results during three days of infiltration show that the sand filter can remove fecal coliforms bacteria at a depth of 150 cm, and provide purified water with a concentration of suspended solids less than 20 mg/liter at a depth of 75 cm.
