The Evac Evolution ballast water management system (BWMS) is based on a combination of filtration and UV technology. Completely chemical-free, it operates effectively in marine, brackish and fresh water.
A unique feature of the system is a feedback ‘loop’ which ensures thorough irradiation of organisms, whilst ensuring that power is used as economically possible.
Developed by Cathelco, the UV transmission sensor system ensures precise UV dosage by adjusting the UV level to different water qualities. It is achieved by taking a sample of sea water before it reaches the UV chambers and measuring the amount of UV light actually passing through it. This works in conjunction with UV intensity meters which are mounted on the chamber and measure the intensity of light which is received.
The system is available with capacities from 34m3/h to 1,500m3/h in a single unit and it can be provided skid mounted or in modular form, simplifying retrofit installations in confined areas.
