Cost reduction in digested sludge dewatering
As partner of KHD Humbold Wedag GmbH, Cologne, ProMinent supplies the polymer preparation station for powdery and liquid polymer for the production of stock solutions or working solutions of synthetic flocculants. The components optimally matched among each other and to the process guarantee an extremely economic overall solution.
Challenge
Process-technical optimisation of the sludge dewatering by an effective and reliable metering of synthetic flocculants (polyelectrolyte)
Solution
- Ultromat® ATFP 2500 2-chamber batch system for the preparation of liquid and solid flocculants to prepare a 0.05 - 0.5 % polymer solution
- Precise addition of the liquid flocculant by using metering pumps
Customer benefits
- Fully-automatic operation with a minimum of staff and maintenance
- Optimisation of the sludge dewatering through high dewatering ratio
- Reduction of the sludge disposal costs by obtaining higher dewatering ratios (high dry matter contents of 30 %).
Customers voice
“Thanks to the effective and reliable generation and addition of flocculants with the polyelectrolyte preparation
and dosing system Ultromat®, we are obtaining a very high dewatering ratio in the generated digestive sludge.
This means that we obtain a relatively dry residual sludge with a very high dry matter contents. We are thus
saving considerably with regard to the disposal of residual sludge”
Dieter Hochdörffer, waste water manager and plant manager of the Landau sewage works
