Maj 13, 2002. Aqua Reci stöds av Stockholm Vatten
I en artikel i Ny Teknik (www.nyteknik.se) nyligen framgår att Stockholm Vatten stöder Aqua Reci processen för slamdestruktion och återvinning av fosfor. Enligt Agnes Mossakowska på Stockholm Vatten har Aqua Reci processen flera fördelar jämfört med konkurrerande metoder:
- Lägre kemikalieförbrukning.
- Bättre energiåtervinning.
- Fosfor återvinns som kalciumfosfat som lätt kan användas för tillverkning av handelsgödsel.
- Anläggningen är mycket kompakt.
- Ingen förbränning ingår vilket underlättar tillståndsgivning.
Aqua Reci processen är ett samarbete mellan Chematur Engineering och Feralco (www.feralco.com). Processen bygger på högeffektiv destruktion av alla organiska föroreningar genom oxidation i superkritiskt vatten. Denna del av processen har utvecklats och patenterats av Chematur och marknadsförs under namnet Aqua Critox. Feralco har utvecklat återvinningsprocessen för fosfor och fällningskemikalier ur den oorganiska rest som återstår efter oxidationen.

March 31, 1998. New aeration system has been inroduced
When substrates such as molasses, starch hydrolysates,
cellulose hydrolysates etc. are fermented to give ethanol, an
equivalent amount of carbon dioxide is formed. Due to the
necessity of adding oxygen to the fermenter during part or whole
of the fermentetion cycle, air is normally added in the fermenter
vessel. The carbon dioxide gets mixed with air, and a recovery of
the carbon will be more costly.
Together with our Biostil licensee in India, Messrs Alfa Laval
(India) Ltd, a revised aeration system has been successfully
introduced in one of the ethanol plants in India, whereby the
required oxygen is added by aeration of the substrate before it
enters the main fermenter. In this way carbon dioxide is recovered
in a very pure form, and more than 90% of theoretical amounts.
The new system can be adapted to any fermentation, and can be
using air, oxygen-enriched air, or oxygen, accordnig to
availability and cost.
