There are mainly two different types of membrane material.
Ceramic membrane vs polymeric membrane.
Opex l j t this means that as far as the cost effectiveness of the ceramic membrane compared with the polymeric one is concerned the determining factor is the ratio of the term l j t for the two materials.
So the membrane replacement component of the opex is then approximately proportional to the ratio of the membrane cost l to the net flux j times the membrane life t.
The trans membrane pressure tmp increase at a constant flux of 150 l m 2 h 1 due to membrane fouling by direct filtration with lake water is investigated for four ceramic al 2 o 3 zro 2 tio 2 sic and a pes pvp polymeric microfiltration membrane s the membrane structures and compositions are characterised with permporometry pore size porosity and xps.
The downside of ceramic membranes is the high sensitivity to temperature gradient which leads to membrane cracking.
This makes these membranes suitable for many applications where polymeric and other inorganic membranes cannot be used.
They are generally used for highly acidic or basic environments due to inertness.
The higher degree of fouling on the polymeric membrane is partly due to its lower volume area ratio compared to ceramic membranes.
The type of membrane used in an application is dependent on waste characteristics treatment objectives and the best economic solution for the plant.
Mass balance analysis shows that 85 8 of the npoc is.
Moreover chemical cleaning efficacy on membrane fouling of polymeric membrane 24 25 and ceramic membrane 26 27 has only been studied in isolation with disparate initial fouling extent and different cleaning protocols.
A number of different polymeric and ceramic materials are used to form membranes.
Consequently cleaning effect on membrane fouling is lack of comparability between polymeric and ceramic membrane.
Distilled water flux for polymeric and ceramic membranes a similar dependence as that for distilled water was observed for all the mem.
Polymeric and ceramic membranes aqua aerobic systems provides two types of aqua multibore membranes polymeric and ceramic.

Ceramic membranes consist of metal aluminum or titanium and non metal oxides nitride or carbide.
