About
SEMEO, founded in 2011 and headquartered in Bréal-sous-Vitré, France, is the mobile effluent and sludge treatment specialist within the SEMOSIA Group, which employs over 300 people and generates approximately EUR 67 million in annual revenue. The company maintains a fleet of more than 100 mobile treatment units available for short-term emergency response within 24 hours or long-term rental contracts, and has treated over 2 million cubic meters of effluents while achieving 80 percent or greater annual waste volume reduction. SEMEO holds ISO 14001 and MASE safety certifications. Each equipment line carries the distinctive -EO brand suffix. FLOTTEO provides dissolved air flotation in 5 to 50 cubic meters per hour with 20 to 50 micron micro-bubble generation for grease, COD, TSS, BOD5, and phosphorus removal. OSMEO delivers reverse osmosis at 120 to 240 cubic meters per hour with 99.9 percent pure output and 20 to 90 bar operating pressure for PFAS treatment, landfill leachate, and firefighting water decontamination. CENTREO offers mobile centrifuge and decanter units for continuous sludge dewatering. BANDEO and PRESSEO provide mobile belt filter press and sludge press options for on-site dewatering. VISSEO handles continuous screw press dewatering, while TABEO delivers drum and belt thickening. DECANTEO supplies mobile clarifiers and lamella settlers, SANDEO separates and dewaters grit, TROMMEL provides rotary screening drums for pre-treatment, AEREO handles aeration and mixing, and BATEO cleans basins and retention tanks. Several product lines, including FLOTTEO, BANDEO, and TUBEO, are manufactured directly by the SEMOSIA Group.
