Crossflow

The effect of different hydraulic cleaning methods was investigated in terms of flux decline and resistance using the cross-flow UF unit. The use of varied production intervals, varied ratios of periodic relaxation and the use of a periodic high-rate crossflow were investigated. This cleaning method

This paper presents an investigation on the removal of hardness by using a crossflow membrane reactor. Lime soda (LS) and caustic soda (CS) were added to hard water as softening chemical agents. The effect of the LS–CS dosage, specific cake resistances (") and transmembrane pressure drop ()P) on ste

Most of the municipal sewage treatment plants (MSTPs) being operated in Korea were designed for wastewater with average concentrations of municipal sewage. However, they are in fact being operated at low organic loading. Thus, most of the secondary small-scale sewage treatment plant cannot satisfy t
