The Ocean Guard system from Desmi consists of three units. First, a filtration unit removes particles, zooplankton and large algae, and comes in sizes ranging from 40m~3/h to 5,400m~3/h. For the basic BWTS 300-P30 system configuration, where space is a limiting factor, a pressurised filter is fitted with a mesh, of pore size 30μm, which removes particles in order to secure the efficiency of the succeeding disinfection step.
