Authors offered a new class of microfiltration membranes ULTRA-J based on
modified polycarbonate with the spatial globular structure. The technology existing
at present allows to make purposefully membranes with effective pore diameter
0,1-5 micron. Low thickness (to 150 microns) and high porosity (to 80 %)
provide a high specific productivity at entrance pressure on membrane
0,1-0,2 MPa up to 0,9 m3/(m2в€™h). An important advantage of ULTRA-J is constant filtration efficiency, which is lightly dependent of the inlet pressure. This
property is due to the rigid addition structure of spatial globular modified polycarbonate. The tests of membranes ULTRA-J at Kamenskvolokno JSC showed the prospects of using them for water pretreatment in industry. Roll-cage modules based on microfiltration membranes ULTRA-J have been recommended
for use in constructing of water cycling system with productivity 100 m3/h.
