| Opis: | Humanity has recently begun to realize that resources on Earth are not infinite and that, consequently, it is imperative for us to start to use them sustainably and renewably. Aligned with this mentality, forward osmosis has been rigorously studied in the past few decades with some commercially available products already on the market. This thesis used one of those products, namely, the Aquaporin HFFO 2 membrane module, and assessed its stability in sodium metabisulfite solution and high salinity without flowing solutions under long-term storage conditions. The sodium metabisulfite preservation part was devised to upgrade the existing guidelines for prolonged storage of fouled membranes and the osmotic drying project was looking at a scenario where the modules would be exposed to a salt solution on the draw side and no flowing wastewater on the feed side. The assessments were made on pristine HFFO 2 membrane modules and with RO water prepared on site. Their performance after exposure was measured with an internal quality control procedure, producing values for water flux, reverse salt flux, normalized reverse salt flux and temperature, which were later compared with the initial values. The findings show us that the sodium metabisulfite and increased salinity have a detrimental effect on the membrane inside of the module, but not enough to be considered damaged and would need to be discarded. More valuable results will be gained if the measurements are done on fouled membranes, as the biggest factor in increasing the lifetime of a module is preventing algal and bacterial growth |
