Reverse osmosis modelling
RO has been around for more than a decade and focusing on modelling alone might has little novelty and contribution to knowledge. Do try to explore more about the applications for membrane filtration and the role new membrane technologies in RO.
For protein extraction i found a protocol that separate phosvitin from egg yolk using ultrafiltration trough 10 MWCO then uses the filtrate. But phosvitin molecular weight is 35 KDa. So how it is...
