SKM Protein Skimmers
SKM Protein Skimmers
SKM PROTEIN SKIMMERS
Engineered with True 2-Minute Dwell Time calibration and fully recirculating architecture. From 7 to 510 LPM - built for serious nutrient export.
Why Professionals Choose SKM Skimmers
Three engineering principles that separate SKM from conventional protein skimmers on the Australian market.
True Displacement Calibration
Chamber volumes calculated after accounting for air-water mixture displacement. The stated 2-minute dwell time is a physical reality, not a gross-volume estimation.
Fully Recirculating Architecture
Independent feed and recirculation loops allow operators to tune air injection without altering system turnover. High-precision control for optimal foam fractionation.
Commercial-Grade Construction
Standard models available in Acrylic and Polypropylene, with other specialty material models available. Custom-sized options ready for the largest applications.
Engineered for Performance
Every SKM skimmer ships complete with advanced features that eliminate daily maintenance and maximise nutrient removal.
True 2-Min Dwell Time
Mathematically calibrated contact time accounts for air displacement and fluid dynamics. No overestimation, no guessing.
Fully Recirculating Design
Independent water feed & air injection loops. Tune skimming without affecting system turnover rate.
Automated Neck Washdown
Integrated cleaning head prevents organic sludge buildup. Maintains peak foam fractionation without daily manual cleaning.
Ozone-Ready Architecture
Dedicated injection port and ozone-safe materials. Advanced oxidation processes for enhanced water clarity.
Tailored Materials
Choose transparent Acrylic bodies for visual inspection, Polypropylene for ultimate durability, or other materials upon request.
Industrial Durability
Perfect for extreme chemical environments, public displays, and harsh aquaculture setups. Built to run continuously.
Custom Drive Options
Standard needlewheel pumps or custom-engineered venturi systems using your pump of choice. Flexible integration.
Scalable Customisation
From 7 LPM units up to massive facilities. Larger custom sizes fabricated for specific footprint constraints.

*System volume represents maximum volume at the calculated 2-minute dwell time. Calculated at a 30% system turnover rate, representing the stocking density and required turnover equivalent to a commercial aquaculture facility. Actual performance varies with bioload, feeding rates, and organic load. Contact BTA for site-specific sizing. Custom sizing available for higher bioloads.
Everything You Need (Except Feed Pump)
SKM skimmers ship complete with all components for immediate installation. Only one item must be sourced separately.
Included Hardware
Everything in the box: SKM Reaction Chamber, Needlewheel Drive Pump(s), Precision Gate Valve, All Required Fittings, Air Silencer & Tubing, Auto-Washdown Head, and Instruction Manual.
Required (Not Included)
One essential component: A separate feed pump is required to supply water to the skimmer. Size to match the "Flow @ 2-Min Dwell (LPM)" for your chosen model.
Custom Engineering
Beyond standard models: Units can be custom-fabricated for specific footprint constraints or scaled for massive aquaculture applications using various materials including Polypropylene.
Built for Serious Nutrient Export
From public aquariums to commercial aquaculture - where protein skimming performance matters, SKM delivers.
Public Aquariums
High bioload systems demand aggressive protein skimming. SKM units sized for continuous operation with auto-washdown eliminating daily neck cleaning.
Commercial Aquaculture
RAS, hatcheries, nurseries, and live seafood holding require reliable nutrient export. Polypropylene models withstand the harshest chemical environments.
Research Facilities
Precise control over air-to-water ratios and contact time. Recirculating design allows independent parameter adjustment for experimental consistency.
