The BTS5 Automatic Drum Micro Filter is a compact, professional-grade pond filtration system purpose-built for koi ponds, small aquaculture setups, and freshwater systems up to 1,200 gallons (5 tons). Combining mechanical micro-filtration, biochemical biological filtration, and UV20W sterilization in a single all-in-one unit, it delivers consistently clear, healthy water with virtually no manual upkeep. At the core of the system is a 316 food-grade stainless steel drum filter screen that intercepts suspended particles ≥50 μm — including fish waste, fine sediment, algae, and organic debris. When debris accumulates on the screen, the intelligent automatic water-level control system triggers a high-pressure self-backwash cycle: the drum rotates while pressurized nozzles flush impurities directly into the sewage outlet — completely hands-free. Constructed from durable, UV-resistant food-grade PP material with a lifespan exceeding 10 years, the BTS5 is engineered for permanent outdoor installation in all weather conditions. Its inclined-bottom design eliminates dead zones and ensures full sewage drainage, while the integrated biochemical filtration chamber rapidly cultivates beneficial nitrifying bacteria for stable, long-term water quality.
