Protein Skimmer: Solutions for Dissolved Solids Separation

What is a Protein Skimmer?

When your RAS water turns murky, the Protein Skimmer steps in—like a tiny bouncer tossing out microscopic troublemakers. It uses foam fractionation to remove dissolved organic compounds before they decompose and pollute your water.

How Protein Skimmers Work

Fine air bubbles pass through the water column, attracting hydrophobic organic molecules. These molecules attach to bubble surfaces and rise as foam, which is collected and removed from the system.

Benefits for RAS Operations

• Removes dissolved proteins, lipids, and phenols
• Reduces biofilter load by up to 30%
• Improves water clarity and reduces yellowing
• Decreases chemical oxygen demand (COD)

Sizing and Selection

Protein skimmers should process 1-3 times your total system volume per hour. Saltwater systems require more aggressive skimming than freshwater due to higher protein levels.

Maintenance Requirements

Empty collection cups daily in intensive systems. Clean air diffusers weekly to maintain fine bubble production. Inspect venturi injectors monthly for clogs.
