 EPCOVAP-MVR, standardisert kompakt MVR inndamper
 MVR fallstrøms inndampere, med ”case studies” fra
biomarin industri
 Nyutviklet overhetet damp tørke med MVR
 EPCON testanlegg
Evaporation
Evaporation is a boiling process for dividing a liquid feed with low DS in a
very pure condensate and a liquid concentrate with high DS.
If not using MVR energy system, evaporation require big amount of
thermal energy supply and cooling water.

SHS-MVR tørken er nylig utviklet, og per i dag
utprøvd og verifisert på mineral produkter. Andre
anvendelser må verifiseres når ny pilot-tørke blir
etablert (innledende tester på egnede væsker er
også mulig idag). Tørking av bio-marine avfalls
fraksjoner/ slam er en mulig anvendelse.
