Facilities for membrane studies

Pervaporation/membrane filtration

The laboratory-scale equipment (P28, Celfa) for micro, ultra and nanofiltration and reverse osmosis and pervaporation. Membrane effective area is 28 cm2 and the maximum volume of the apparatus is 500 cm3.

 
Pervaporation unit

Dead-end pervaporation unit with flat membrane module. Separation and dehydration of organic compounds form aqueous solutions and separation of organic mixtures. The membrane effective area is 78.5 cm2 and the tank capacity is 1 liter.

 

Ultrafiltration stirred cells

The ultrafiltration stirred cell is a dead-end unit designed for rapid concentration or purification of macromolecular solution up to 400 cm3. The ultrafiltration membranes used are flat sheet membranes with an effective area of 41.8 cm2. The maximum pressure recommended is 4 bar.

 

Pilot-scale tubular membrane unit

The tubular membrane unit for micro, ultra and nanofiltration as well as reverse osmosis. The maximum volume of the apparatus is up from 10 liters, and the maximum pressure can be up to 55 bars.

 

Membrane filtration units

The laboratory-scale Millipore Pellicon and Prostak equipments are in use in micro and ultrafiltrations. The membrane area is from 0.5 to 2.5 m2, depending on how many cassettes (1-5) are used.

 

Membrane separation equipment for gas separation

Laboratory scale membrane separation unit for purification of gas mixtures. The unit consists of one or more adaptable membrane filters for the separation of different gases such as CO2 and methane. The equipment is constructed of noncorrosive materials. The analysis of the gas flows (e.g. CH4, CO2 and H2S) can be measured on line. The maximum pressure recommended is 20 bar, the maximum temperature is 60°C and the gas flow rate is 0-10 l/min.

 

ÄktaCrosflowTM Filtration system

Automated bench scale (40-500 cm2) filtration system for cassette and hollow fiber crossflow filtrations for screening and process optimization. Flexible use of membranes of different manufacturers. Working volume from liters down to 25 ml.
