Flux enhancement

We demonstrate the immobilization of graphene oxide on polytetrafluoroethylene (PTFE) membrane surface for desalination via direct contact membrane distillation. The graphene oxide immobilized membrane significantly enhanced the overall permeate flux with complete salt rejection, and the flux reached as

The reduction in permeate flux caused by fouling is a drawback in the operation of membrane systems that can be alleviated using mechanical and electrical methods. Alternatively, physicochemical treatments provoking the elimination of fouling agents have been proposed as effective strategies for the

This paper presents a review of some of the key methods of generating flow instabilities that have been implemented in membrane separation processes by various workers during the past few years (mainly the 1990s). The types and effects of incorporating these techniques are discussed based on the exp

T he improvement in the flux as a result of o perating the plant in a cyclic model was s uccessfully predicted by the simple model. The m odifications applied to the model lead to p ermeation rates which were in close agreement w ith the experimental data for the considered f orcing functions, namel
