摘要
为克服海水反渗透(SWRO)脱盐技术存在的预处理污泥体积大和总体水回收率低两大问题,提出了一种新型的混合反渗透正渗透(RO/FO)系统,在MATLAB中开发了RO/FO混合系统的软件,并对不同的水通量值进行了验证.通过在RO/FO系统软件界面设置不同的操作参数,可以在多种不同的选项中快速估算出预处理污泥体积的减少百分比、RO整体水回收率的增加量、所需FO膜面积以及RO废渣的稀释率.
Seawater reverse osmosis(SWRO)desalination technology is being widely used in coastal countries to meet the supply demand of fresh water for living and industry using.Despite major advancements in SWRO technology,the desalination industry is still facing significant practical issues.Generation of higher volumes of pretreatment sludge and low overall water recovery are the two of the major issues.A novel hybrid reverse osmosis-forward osmosis(RO/FO)system has been proposed to overcome the above two drawbacks.After that,a software for the RO/FO hybrid system in MATLAB was developed,and different water flux values were studied to verify the system.By setting different operating parameters in the RO/FO system software interface,the per-centage reduction of pretreatment sludge volume,increase in overall RO water recovery,FO membrane area required and dilution in RO reject can be estimated quickly in a variety of different options.
