Cellulose Recovery
Process
Two sieving steps
The CellCap® technology contributes to plant optimisation and closed-loop recycling by filtering out most of the cellulose in the effluent at the pre-treatment stage. A two-stage residue stream is created at the very beginning of the treatment, generally used for generating biogas and extracting a relatively clean cellulose stream.
Sludge management
CellCap technology means up to 20% less sludge. A considerable advantage when you consider the energy cost of dewatering sludge, the cost and environmental impact of using chemicals and disposing of dewatered sludge.
Hydraulic capacity
CellCap® extracts residues and cellulose at the beginning of the water treatment process, resulting in a significant reduction of suspended solids (up to 40% of the total). As a result, the technology is expected to increase the hydraulic capacity of the plant by approximately 15%.
Environmental impact
From sewagewater to Recell®, CellCap technology is a concrete example of the circular economy, as each tonne of cellulose recycled from wastewater saves between 3 and 5 trees and up to 2.5 tonnes of CO2 emissions, depending on the installation.
