Terragon has developed the highly innovative WETTTM-O (Wastewater Electrochemical Treatment Technology for Oily Water), the first Type Approved electrochemical treatment system for marine oily bilgewater.
The system has received USCG and IMO MEPC.107(49) certification and can treat to 5 or 15 ppm discharge as selected by the operator. WETTTM-O meets the most stringent discharge standards available for shipboard Oily Water Separators.
The system has been evaluated on commercial and government vessels, and is immune to the effects of ship motion including pitch, roll and vibration.
WETTTM-O can also be used for other oily wastewater, such as vehicle wash water and industrial oily water
WETTTM-O is a lightweight compact unit based on coalescence separation of free oil in a free oil separator (FOS), followed by one or more proprietary self-cleaning anti-passivating electrocoagulation (EC) units and a fluorescence-based Type Approved Oil Content Monitor (OCM).
WETTTM-O breaks the oily emulsions contained in bilge water and produces an effluent with less than 5 ppm of oil. As well, it removes many pollutants such as large solids, suspended solids, free oil, colloids, organics, phosphorus and heavy metals.
The WETTTM-O features include:
Effective, compact and robust
Makes use of sacrificial metal electrodes
Significantly reduced maintenance
Operates continuously 24/7 without operator attendance
Treatment capacities between 1.44 m3/d (380 gal/d) and 10.8 m3/d (2853 gal/d)
Option of selecting 5 ppm or 15 ppm discharge setting
WETTTM-O does NOT require:
