Optimise aquaculture health with protein skimmers

Our protein skimmers are efficient and ready to use, with applicational use in aquaculture, aquaria and wastewater facilities. Microbubbles injected by the venturi drives ensure capture and removal of excess proteins in the treated water column to provide high water quality.

Removal of proteins

Foam control in RAS

Suited for ozone injection

Treating water

Our protein skimmers can be installed in a wide range of aquaculture facilities and are currently used to treat water in salt- and freshwater RAS and model trout farm systems, inlet water for flow through systems and as end of pipe treatment in fish processing plants. The simple design allows for easy setup. 

Other features include: 

  • Non corrosive plastic materials 
  • Individual venturi drives designed for both fresh- and saltwater applications
  • Ready for ozone injection 
  • Large foam chamber ensures foam to collapse resulting in low water use for backwash 
  • Time or sensor controlled backwash system
  • 7 sizes readily available 
  • Custom made skimmers on request, designed for desired flow and contact time 
  • Produced in Germany

Suited for ozone

Our protein skimmer models are suited with ozone injection points, off gas ventilation for treatment of excess ozone gas and a loop re-injecting degassed ozone from the foam chamber. Ozone improves coagulation and foam formation in the protein skimmer.

Working principle

The working principle of the protein skimmer is applying the physical and chemical properties of microscopic air bubbles to bind and entrap dissolved protein and particles. As low density foam rises to the chimney of the protein skimmer, the particles bound in the foam will exit the water column and is collected for final treatment.

Frequently asked questions

Why is protein skimming important in aquaculture systems?

Protein skimmers help maintain water quality by removing organic compounds that can lead to poor water conditions and stress for aquatic organisms. This improves overall health and growth rates in aquaculture systems.

What types of aquaculture systems can benefit from protein skimmers?

Protein skimmers are beneficial for a wide range of aquaculture systems, including fish farms, shrimp farms, and marine hatcheries. They are particularly useful in closed-loop RAS setups where water quality control is crucial.

How do I choose the right protein skimmer for my aquaculture operation?

Factors to consider include the system size, the species being cultured, and the waste load. It's essential to consult with an aquaculture equipment specialist to determine the best skimmer for your specific needs.

What maintenance is required for protein skimmers?

Regular maintenance is essential to ensure skimmers operate effectively. This includes cleaning the collection cup, adjusting the air and water flow rates, and periodically replacing or cleaning air stones or diffusers.

Can protein skimmers be integrated into existing aquaculture systems?

Yes, protein skimmers can be retrofitted into existing systems to improve water quality and overall performance. An experienced technician can help with the installation and integration process.

Are there any environmental benefits to using protein skimmers in aquaculture?

Yes, using protein skimmers can lead to more sustainable aquaculture practices by reducing the need for excessive water exchange and chemical treatments, thus minimising environmental impact.
