Liquid filters

We spend years here developing it all !

As to the invitation from Robert Goldsmith from CeraMem, Waltham, Massachusetts, USA in 1997 we entered the world of ceramic filters for particle separation from liquids. The collaboration was divided so our LiqTech company 1997-2000 took care of the development of giant SiC carriers 5,66x34 inch (144 x 864 mm) as replacement of the similar size Corning Cordierite carriers. CeraMem took care of the oxide ceramic membrane cast onto the carrier.

Such big SiC monolith had never been designed, developed or manufactured by ANY. Our little company LiqTech succeeded this enormous task when LiqTech was 100% ours.


We managed and produced hundreds of these giant carriers for CeraMem. This was all screwed up when I invited investors into LiqTech in 2002. One of many big mistakes in my life! I sold my shares and left my own LiqTech in 2004 to recover.
