MEMBRANES   10 FEBRUARY 2015

 

20150210 Sulzer Chemtech Ltd. - Mr. David Gladman & Mr. Jeffrey Felix –“Pervaporation and Vapour permeation: Scale-up with a hybrid bench test unit (BTU)”

Sulzer has a leading position in the design and installation of PV and VP systems (>200) Most applications are in dehydration of organic solvents, separation of organic mixtures and recovery of volatile valuables from aqueous mixtures in chemicals, pharma, food & fragrance, biofuel and bio-refinery. Their experience allows Sulzer to design full scale units on basis of their versatile BTU in which Sulzer tests new membranes, membranes & module geometries, applications, stability, flux, selectivity, process parameters. The BTU, the underlying principles and the test approach were elucidated with the scale-up possibilities to flat polymer and tubular ceramic membranes. www.sulzer.com

 

20150210 SolSep B.V. – Mr. Petrus Cuperus & MACT - Mr. Ton Franken - “Technoproject results: Recovery of Hexane/Acetone from Hexane/Acetone Oil extraction liquids in edible oil industry”

Membrane & Module Manufacturer for non-aqueous solvent systems SolSep and membrane application centre MACT have cooperated with NL GUTS members IOI LodersCroklaan and Cargill to test the possibility of solvent resistant nanofiltration SRNF to debottleneck distillation for recovering acetone and hexane form edible oil extraction and reduce energy consumption. Pilot rig, approach, membrane selection, experimental results on critical parameters, module characteristics, run time, performance stability for different oil fractions and economic feasibility were presented. The results are very encouraging. A large pilot will be prepared. www.solsep.com www.mact.nl

 

20150210 BiAqua B.V. – Mrs. Sandie Chauveau – “Biofouling of membrane systems by phosphate limitation”

The start-up BiAqua developed a novel approach (invented by TUD) of combating bio-fouling by selective phosphate removal from the feed water, which stops the growth of micro-organisms. Phosphate is adsorbed to below 1 μg/l on a bio-degradable adsorbens, containing iron with good affinity to phosphate. The adsorbens in a normal sand-filter or IX housing is operated as such and can be regenerated multiple times with caustic.Pilot on drinking water and secondary wastewater treatment effluent proved effective and stable, resulting in constant low pressure drop over RO modules that otherwise exhibited severe bio-fouling. Applications in surface water, horticulture, cooling towers are developed with partners. Outlook for 2015 is demo scale. www.biaqua.nl

 

20150210 MetalMembranes BV – Mr. Sybrand Metz – “Nanoporous membranes made out of metal”

MetalMembranes developed hard crystalline porous α-Al2O3 membranes from Al on a titanium support with plasma electrolytic oxidation. In the original metal Al layers flow channels are etched to form a well defined flow pattern with access to the actual membranes. The membranes have a high porosity with straight quite accurate pore sizes of 100-150 nm with 50-150 μm thickness. Permeate channels are etched in the Ti support layer. The flat sheet membranes are stacked to form modules. When using Ti as starting material pores of < 10 nm can be made.
They feature high clean water fluxes (> 3.000 l/(m².h), recoverable after cleaning.
Applications are tested in prototypes for fast growth detection of micro-organisms, for electro-filtration of cells (>500 l/(m².h) and other. www.metalmembranes.nl

 

20150210 MicroSieve Technologies GmbH (CH) – Mr. Franz Lieberman - “High Frequency Flow Reversal for continuous micro-, ultra- and nanofiltration with flat high performance membranes”

MicroSieve Technologies (MST) focuses on flat sheet micro-sieves with smooth surfaces and well defined straight pores and on maximizing the high fluxes these membranes in principle have. High fluxes cause rapid cake layer formation and flux decline. MST developed the sieve vacuum cleaner (HFFR High Frequency Flow Reversal) that combines permeate flow reversal by frequent back pulses and cake layer removal through a suction slot rotating at the feed side of the micro-sieve. Membranes and HFFR are stacked to make modules. As only the cake layer with a bit of feed is removed little liquid (<1%) is lost. Using the rotating slot abandons the necessity of pump energy to create shear forces, reducing power consumption, while maintaining high fluxes for beer, whey and milk between 5.000 and 25.000 l/(m².h.bar) at 0,2 bar feed pressure. MST cooperates with Aquamarijn in NL. www.microsieve.net

 

20150210 VITO NV (BE) – Mr. Pieter Vandezande – “Volume intensification of macrocyclisation reactions using membranes“

Reactive systems that require dilution to accomplish minimum yield, to prevent by-products & side-reactions or to avoid limitations from high concentrations of reactants feature high solvent use and large batch reactors while conversion is <100%. VITO developed the membrane assisted VID (volume-intensified dilution) process that increases yield, reduces solvent use by > 50% with 100% conversion potential. One approach is to place an NF membrane on the reactor that retains substrate and products and returns solvent to the upstream solvent – substrate mixing tank. Another approach feds solvent and reactants separately to a mixer/reactor that discharges into a separation tank, to which the NF membrane is connected. Both are effective depending on the reactive system. In a second part VITO demonstrated that 90% of API van be recovered from waste liquids through combining concentration and solvent diafiltration with OSN. www.vito.be

 

20150210 TNO – Mr. Albert Jansen – “Industry Award winning Mempower”

TNO received the Aramco Entrepreneurship & GE Award for its MemPower process that combines High Pressure Membrane Distillation of seawater with the production of electricity using waste heat. The normal MD principles apply, however only at high pressure. Proof of principle tests were positive. Different scenarios to produce 20 MW of power by combining solar heat and steam power generator with RO, MED or MemPower indicate that the MemPower combination requires 20% to 15% less solar heat, 30% to 17% less power and produces twice as much drinking water from the sea, than the others. Next phase is proof of concept. www.tno.nl

 

20150210 Pentair B.V. Mr. André Mepschen - “Pentair and Experiences in beer filtration”

Besides the X-Flow XIGA modules for water treatment, Pentair uses X-Flow membranes in special modules for beer membrane filtration BMF. BMF replaces diatomaceous earth DE filters, that produce high volumes of organic laden waste for disposal. With more than 50 commercial operating plants globally experiences can be summarized as: more sustainable, better + constant beer quality, same CAPEX, les OPEX, fully automated and simple process. The design, engineering, operation and cost aspects were reviewed including an explanation in the workshop. www.pentair.com
