Abstract
This paper describes the reverse osmosis tests which were carried out on shower and laundry wastewater using dynamically formed zirconium oxide - polyacrylate membranes which were formed in situ. Performance data consisting of solute rejection and product water flux, as depending on several operating parameters, are presented. These parameters are : operating pressure with the range 8 × 105 N/m2 to 7 × 106N/m2, temperature with the range 76°C to 93°C, circulation velocity with the range 1.7 m/sec to 8.2 m/sec, and feed concentration ranging from normal to 14 times normal. Data presented include rejections of organic material (TOC), ammonia, urea, and several ionic species.
