Summary

NIVA has developed methods permitting an efficient control of lime dosers in streams. The control involves simple sensor technology and an efficient information flow. This system is used to improve on and ensure a cost-efficient liming. The information generated is processed and reported by NIVA and is an aid to operators and water managers. This report summarizes deviations from optimal operation detected during 2019. Measures to improve the operation are suggested.
