TRAIDENIS
About
JSC Traidenis, founded in 1996 in Alytus, Lithuania, was the first Lithuanian company to manufacture wastewater treatment plants from glass-reinforced plastic (GRP). Using proprietary Cross Filament Winding technology with production lines installed in 2007 and expanded between 2011 and 2018, the company produces cylindrical tanks up to 5 meters in diameter and modular systems reaching 5,000 cubic meters capacity. Their residential NV-type wastewater treatment plants achieve 95–98% pollutant removal without internal moving parts, available in NV-A (two-chamber), NV-M (with integrated sludge dewatering bags), and NV-T (with sludge thickening) configurations, plus the fifth-generation NV Comfort line with simplified maintenance. The HNV-type modular biological treatment systems serve settlements from 200 m³/day upward, scaling through modular expansion for growing communities. Traidenis also manufactures chemically resistant tanks using Derakane and Hetron resins rated for pH 0–14 and temperatures from -50°C to +150°C, triple-wall thermo-insulated tanks with polyurethane insulation providing 4.8 m²·K/W thermal resistance, GRP pump stations, oil separators rated for 1–5 L/s, biogas scrubbers for hydrogen sulfide removal at anaerobic digestion facilities, firewater reservoirs, silo tanks, and closed-loop aquaculture recirculating systems. The company holds ISO 9001 and ISO 14001 certifications, provides a 20-year structural warranty on underground tanks, and exports to over 27 countries across Europe and Asia.
