Ships and marine technology — Ballast water management systems (BWMS) — Computational physical modelling and calculations on scaling of UV reactors
Preview
Summary
This document specifies the methodology to conduct computational modelling of ultraviolet (UV)
reactor designs for ballast water management systems (BWMS) that incorporate ultraviolet
disinfection technology (UVBWMS). The computational modelling is used to calculate the UV reduction
equivalent dose (RED) and to compare calculated REDs of the scaled reactor to its base reactor. REDs
are determined using organisms with a given dose response.
NOTE The IMO requires validation of the computational model.
The simulation of a physical UV reactor using a computational model requires that the model be
validated (i.e. it performs as intended and reflects the correct physical constraints) and verified (i.e.
produces outputs consistent with empirical data). A model developed according to this document
is intended to validate the performance of simulated but untested, scaled UV reactors, where the
simulation has been verified with test data from base model UV reactors within the product line. As a
complete UV BWMS typically incorporates other treatment methodologies such as filters, the impact of
changes to external subsystem performance on the overall BWMS is not considered in this document.
