纳诺斯通陶瓷膜及DTRO技术培训资料

1、CUF Design Data,Operation Flux: 100500lmh,有机膜预计通量的36倍 Backwash Flux: 34 X operation flux CIP flux: 1 X operation flux Turbidity Limits: 1000 NTU (Consult NSW if above) Total Suspended Solids Limits: 500 mg/L (Consult NSW if above) Feed water Oil Content: 1,000 mg/L (Consult NSW if above) pH Range: 1

2、-13 65C,CUF Value,Longer Membrane Life 膜的寿命更长 No Fiber Breaks 无断丝 Higher Suspended Solids Tolerance and organics/bacterial 对于悬浮颗粒物和有机物/微生物容忍程度更高 Higher Water Recovery Rates 回收率更高 Higher Chemical Stability 化学稳定性更高 Wider Operating Pressure Range 操作压力的范围更宽 Higher Temperature Limit 耐受温度更高 Lower Rack CAP

3、EX 机架投资降低,CUF Competitor,Flow Schematic Dead End Service,Similar to polymeric pressurized hollow fiber UF/MF 类似中空纤维膜的UF/MF 500-1000 screen filter vs. 150-500 500-100u格栅过滤 vs 150-500u Higher recovery rates than polymer (97%) 比有机膜更高的回收率（90%） Top or Bottom Feed 顶端或底部进料,流程示意图-死端过滤,5,Flow Schematic Cross

4、 Flow Service,Similar to Inside out polymeric UF (Older Koch, Hydanautics, Norit） 类似内压式有机UF内循环方式（如：科氏Koch，海德能，诺瑞特） Recycle flow with or without bleed 循环侧：有浓水排放/无浓水排放 Periodic backpulse to drain. 间歇周期反冲，冲洗水排放,流程示意图-错流过滤,6,Flow Schematic Backpulse,High pressure backpulse (5 bar). 高反洗压力（5bar） Short dur

5、ation (2-10 seconds) backpulse. Backpulse Fluxes 900-2500lmh. 反洗时间短（2-10秒）。反洗通量900-2500lmh May or may not need backpulse reservoir tank. 需要或者无需反洗储水池,流程示意图-定时反冲洗,7,Flow Schematic - Capillary Purge(Feed),Purge solids from channels during or after backpulse 清洗液在反洗时或反洗后加入 Purge with air for higher recov

6、ery 高回收率时可采用气洗,流程示意图-清洗路由(清洗液),ST valve proposition,Difficult to treat high TDS waste re-concentrating High COD tolerance Shorter Pre-treatment, lower CAPEX Minimize the evaporator scale, Reduce overall CAPEX and OPEX,7/21/2020,8,Main Competitors,ST/DT Shorter pre treatment, no ion exchange and de-c

7、arbonator Higher hardness/high COD tolerance More simple operation Up to 120,000mg/L TDS in reject 2 reference(1operating) in CTX,HEROTM Up to 80,000mg/L TDS in reject 5 or more references in CTX EDR Up to 100,000mg/l TDS in reject No operating reference in CTX Vibrating RO Up to 80,000mg/l TDS in reject 2 reference(1operating) in CTX Forward Osmosis Up to 140,000mg/l TDS in reject 1 reference(not
