BalPure Severn Trent de Nora

摘要

BalPure, from the US joint venture of Severn Trent Services and Gruppo DeNora, only treats ballast during the uptake on the ballasting operation although a second operation during de-ballasting is done to neutralise and residual oxidants remaining from the treatment stage. Ballast water is first cleared of larger organisms and sediments by a 40(im filter. Once filtered, a slip stream of 1 % of the total water ballast uptake flow rate is fed to the BalPure system where a hypochlorite disinfection solution is generated.
