The company’s product range covers mixing, aeration, fluid conveying, and solid-liquid separation. Mixing and flow-promoting equipment includes submersible mixers in standard, energy-saving, permanent magnet, and stainless steel configurations, along with submersible flow promoters and MBBR media fluidization units. These are designed to eliminate dead zones in anaerobic and aerobic tanks, with permanent magnet models reducing energy consumption by 20 to 30 percent compared to conventional motors.
Aeration equipment spans deep-water mixing aerators, centrifugal aerators, and jet aerators. Deep-water units operate at depths up to 50 meters with oxygen transfer rates reaching 2.5 kilograms per kilowatt-hour, while centrifugal aerators serve shallow tanks and open basins with air flow rates up to 20 cubic meters per minute. Jet aerators feature no underwater moving parts, making them suitable for small-scale and rural treatment systems.
Fluid conveying equipment includes submersible return pumps handling solids up to 50 millimeters in diameter and axial flow pumps with flow rates up to 5,000 cubic meters per hour for low-lift, high-volume applications. Solid-liquid separation equipment rounds out the portfolio with bar screeners achieving 95 percent screening efficiency, shaftless screw conveyors for viscous sludge, bridge and chain-type sludge scrapers, and sand-water separators for grit removal.
Blue Collar holds four utility model patents covering a new reducer for water treatment, an optimized submersible mixer design, an adjustable mounting bracket, and a folded rear blade sealing structure. The company’s quality system includes 72-hour continuous operation trials, hydraulic efficiency testing, and corrosion resistance verification using 96-hour salt spray tests.
All products are built with 304 or 316L stainless steel for corrosive environments, carbon steel with epoxy coating for general applications, or engineering plastics for lightweight requirements. Customization options include power ratings from 0.37 to 110 kilowatts, flow rates up to 5,000 cubic meters per hour, and water depths from 1 to 50 meters.
With ISO 9001, CE, and RoHS certifications, the company serves clients across municipal wastewater plants, industrial facilities, aquaculture operations, and water reuse projects. Its after-sales network provides on-site commissioning, operator training, and spare parts delivery from a Shanghai-based warehouse.
