Dual Stage ULTRA-SEP® Bilge Water Separators optimize performance in both processing phases for separating and removing free and emulsified oils from bilge water. The first stage efficiently removes free oils using our HELI-SEP® coalescing separator, which is familiar to ship operators worldwide. More than 6000 units in service around the world are proof of reliable performance. The second stage - the critical component for satisfying IMO MEPC.107(49) regulations for treating emulsified oils uses proprietary SPIR-O-LATOR® ultra-filtration membranes. ULTRA-SEP® is available in eight models with capacities ranging from 0.25m³/hr - 10m³/hr
