PROCESS FOR FLOCULATING SUSPENDED MICROSCOPIC PARTICLES IN A LIQUID AND APPLICATION TO THE COLLECTION OF PHYTOPLANCTONIC MICROALOGUES AND ZOOPLANKTON IN SUSPENSION IN WATER

摘要

THE INVENTION RELATES TO A PROCESS FOR FLOCCULATING MICROSCOPIC PARTICLES IN SUSPENSION IN A LIQUID. /P P A FIRST LIQUID INCLUDING MICROSCOPIC PARTICLES IN SUSPENSION IS PASSED THROUGH A FIXED LIT GRANULAR MEDIA BY COLTIA 2 JUSTICE 2. OR COMPLETE OF THE SAID GRANULAR MEDIUM BY THE SAID MICROSCOPIC PARTICLES, THE GRANULAR MEDIUM AT LEAST PARTIALLY IS DECOLMATED IN A FIXED BED BY MAKING IT THROUGH A SECOND LIQUID, CIRCULATING IN THE SAME DIRECTION AS THE FIRST LIQUID, BUT FAST AT A SPEED AND DOWNSTREAM OF THE SAID BED IS RECOVERED, FLOCCLE 4 AGGREGATES OF SAID MICROSCOPIC PARTICLES AND A LIQUID EFFLUENT 6. /P P APPLICATION TO THE COLLECTION OF MICROALGAE AND ZOOPLANCTON.
