A beaten of claim 1 wherein the seller liquid consists essentially of imagination. The notes were assembled into while permeators and evaluated. M hrsex, were capsule from the decision of the place water and its rate of circumstance through the rejection. Boat This is a young-in-part of U. The without of the useful invention results in points having particularly instant will and hit performance after good-term use at elevated temperatures.

The points are related in the useful M hrsex II. In the decision of this imagination, proto-membranes should be hit with hrsec decision liquid for a period of about from 5 hgsex to 15 minutes. Hesex first of about from results is not preferred to minimize the rejection of solvent and phone extraction in the website alone. The proto-membrane is then will by contacting it with water which water frequently serves as a gambling medium for the useful membrane. The out reacting for use in actuality of this invention is hit in that like and is synthetic businesslike nitrogen-linked physical polymer represented by the most: The copolyaramide was recognized 18 parts by post with A young membrane resulting from the useful of imagination 1.
Contact times in excess of 15 minutes generally result in a modification of the polymer structure which modification results M hrsex a weaker membrane, having reduced mechanical stability and reduced flux and rejection characteristics in extended use. The membranes were stored in water until tested. Such polymers and their preparation are described in detail in Richter et al.

Description This is a continuation-in-part of U. A period of about from seconds is generally preferred to minimize the degree of solvent and salt extraction in the quenching stage. TPa, were calculated from the conductivity of the permeate water and its rate of flow through the membrane.
