活性砂過濾器工作原理

1、活性砂過濾器工作原理活性砂過濾器工作原理過濾物料過濾物料型式 密度 (kg/ m ) 成本 (EC U / m ) 化工濾料 活性碳 無煙煤 石英砂 花崗巖砂 磁粉 1000 1200 1400 2650 4100 5000 2000 800 400 175 2000 2500 過濾的機(jī)理Transport to sand particle移動(dòng)到砂粒Attachment to sand particle吸附到砂粒后Molecular diffusion分子擴(kuò)散Sedimentation沉淀Chance contact偶然接觸Straining變形Surface forces表面張力進(jìn)水進(jìn)水洗砂
