consumption in Water Treatment Plant. This study is focus on the comparisons between
variable Speed Drive, VSD and RVSS to assess the pumping performance as well as
energy efficiency in the WTP system. Based on the Layne Bowler pump characteristic, it
clearly proved that the VSD is more reliable in term of speed and energy usage compared to
RVSS. As results, by using VSD it will bring a lot of benefits for long term application and …
