05/03/2023Enhanced dewatering | Web meeting |Severn Trent Water| 2016 5
Kemira support for Total Cost Reductionand meet regulation with combination of enhanced dewatering and SMART technology
Reduce sludge
disposal costs
Prevent struvite scaling
Reduce polymer
consumption
Improve centrate/filtra
te quality
Impact the highest cake solids (2-3 % minimum increase)
Phosphorous removal at dewatering stage(> + 30% removal)
Chemical performance optimization
Better [TSS ] & [Phosphate]

Confirmed customer benefits with enhanced dewatering program
Removes P from centrate Struvite avoided (10-20 k£/y)
Pipe protection
and avoiding maintenance
costIncrease cake solids (~2 to 5 %)
Reduced costs associated with
polymer dosage &
sludge management C&M to secure
the system and get more savings on dewatering process
Ensure compliance
/ reduce risk of failure/ penalty
