The BTS50 Automatic Drum Micro Filter is a heavy-duty, commercial-grade pond filtration system engineered for large koi ponds, professional aquaculture farms, and high-volume freshwater systems up to 12,000 gallons (50 tons). At the top of the BTS product line, it delivers industrial-scale mechanical micro-filtration, biochemical biological filtration, and dual UV40W sterilization — all in one fully integrated, self-maintaining unit capable of processing 13,450 GPH continuously.

Powered by a 370W high-capacity pump and a 120W motor, the BTS50 handles the most demanding large-volume water treatment needs with ease. Its 316 food-grade stainless steel drum filter screen intercepts suspended particles ≥50 μm — including fish waste, organic debris, fine sediment, and algae — across dual DN100 (4-inch) inlets for maximum throughput. When the filter screen reaches capacity, the intelligent automatic water-level control system triggers a simultaneous high-pressure backwash cycle: the drum rotates while pressurized nozzles flush all accumulated impurities directly to the DN65 sewage outlet — 100% hands-free.

Dual UV40W sterilization lamps deliver twice the pathogen-neutralizing power compared to single-lamp systems, making the BTS50 the ideal choice for high-density koi environments or commercial aquaculture operations where water quality directly impacts livestock health and yield.

Constructed from food-grade PP material rated for 10+ years of outdoor use, it withstands continuous exposure to UV, heat, rain, and corrosion without performance degradation. The large-capacity biochemical filtration chamber rapidly cultivates nitrifying bacteria colonies, establishing a robust, self-sustaining biological filtration cycle for consistent, long-term water clarity.

Safety & Maintenance Notes:
• Never run the water pump dry — always ensure water flow before starting
• Stop the pump fully before adjusting any valve settings
• Regularly inspect nozzles for blockage; clean or replace promptly as needed
• Protect all electrical components from water overflow or splash at all times
• Follow pump operation manual guidelines for daily maintenance procedures
• Never disconnect pump fittings or unions while the pump is running
