AquaFoam Protein Skimmers

Protein Skimming, or foam fractionation, is a valuable mode of filtration when used with closed-recirculating systems. Both saltwater as well as freshwater systems can benefit from protein skimming especially with systems carrying intense fish loads.

Only Protein Skimming can:

- Remove solid/dissolved
  organic waste

- Increase dissolved oxygen

- Reduce the biological
  demand on the biofilter

- Improve water clarity

Emperor Aquatics  Foam Fractionator diagram. How It Works

Protein Skimming is accomplished by injecting "Micro-Fine" air bubbles into the water stream (venturi injector) entering the contact reactor.

The "Water-Air" mixture is held inside the contact reactor for a predetermined retention time (60-120 seconds). During this retention time, the fine air bubbles are given the chance to accumulate dissolved organic wastes and tiny particles on their bubble walls.

The many "Micro-Fine" air bubbles, laden with organic waste eventually rise to the top of the contact reactor where a dense foam collimates.

Once the foam collimates at the top of the reactor, it begins to slowly but continuously climb upwards into a foam collimation tube/s where it works its way out of the reactor, falling into the waste collector. When foam exits the reactor the protein skimming process is complete.

Note: Waste effluent will vary from a light colored, yellowish liquid to a dark green. A dark color effluent has less water content, representing a more concentrated waste. Dropping the water level inside the reactor and increasing the foam collimation time will produce a more concentrated waste effluent.


AquaFoam PVC Series Advantages:

1. Our exclusive "Dual-Venturi Air Injection Manifold” allows precise air/ozone injection adjustments. This dual venturi injector arrangement allows one injector to be adjusted to the ozone equipment’s precise requirements while the other injector operates independently.

2. The inlet’s pressure gauge allows for precise adjustments between the venturi injectors and the manifold’s raw water feed to the contact vessel.

3. The waste collector can be easily disassembled for periodic cleaning, if required, and is constructed of durable PVC.

4. Connect our waste collector’s wash-down nozzle to a pressurized fresh water source to remove solids that will accumulate on the foam collimating tubes inside the waste collector.

5. The outlet port’s valve controls the column height inside the reactor vessel during operation. An outlet stand-pipe can be added to ensure a precise water level.

6. The Opaque Heavy-Wall PVC construction eliminates algae growth inside the vessel while increasing durability and longevity. The PVC body’s durability also lends itself to resistance from shipping damage.

*Easy to assemble, disassemble, and operate.

AquaFoam Poly Series Advantages:

1. Water flowing through the contact vessel is recirculated by the “Dual Venturi Air Injection Manifold”. This dual venturi injector arrangement allows for independent, precise injector adjustments that are critical especially with the use of ozone.

2. Our inlet pressure gauge, critical to operating efficiency, identifies the pressure before the venturi injectors.

3. The venturi injector manifold’s pump supplies water to the venturi manifold and waste collector wash-down nozzle.

4. The outlet port’s valve controls the column height inside the reactor vessel during operation. An outlet stand-pipe can be added to ensure a precise water level.

5. The waste collector can be easily disassembled for periodic cleaning, if required, and is constructed of durable PVC.

6. Connect our waste collector’s wash-down nozzle to a pressurized fresh water source to remove solids that will accumulate on the foam collimating tubes inside the waste collector. Cleaning can be automated with our timer initiated solenoid valve.

7. Durable polyethylene construction increases longevity and virtually eliminates the possibility of shipping damage to the contact vessel.

*Easy to assemble, disassemble, and operate.



Combining Ozone with Protein Skimming

Ozone is an unstable oxidizer and therefore we recommend its use only in freshwater applications. Combining protein skimming and ozone enhance foam collimation performance by reducing bubble size and oxidizing dissolved organic wastes.

WARNING: Using ozone requires careful consideration. Ozone off-gas, entering the atmosphere, is hazardous to humans and animals in a confined area. Also, uncontrolled ozone residuals in the water may affect the system’s inhabitants causing damage to tissue or even death.

Another important consideration when implementing ozone, is the purity of gas being fed to the ozone generator. Humidity and nitrogen (80% nitrogen in air) can easily and quickly foul the generator’s internal ozone producing components rendering it useless.

When preparing the feed gas, removing moisture prior to the ozone generator is critical to the equipment’s efficiency. Ozone output can be tripled by stripping nitrogen from the air and supplying the ozone generator with 97% oxygen while keeping the generator clean and free of nitrogen by-products.



Delzone Corona Discharge Ozone Generators
Features include 20 kHz frequency, ceramic tube dielectric
ozone generator cells for consistent, reliable ozone production. Delzone models CD-2 to CD-45 feature configurable feed gas options, multiple safety features and sturdy reliable construction.



Dual Venturi Air Injection
Our dual venturi injection manifold allows ozone injection through a dedicated venturi injector without disturbing the main air venturi injector. Using a dedicated injector will maximize ozone solubility, because it allows for precise air/oxygen adjustments through the ozone generator.

Applications
Brood Stock/Grow-Out – Whether your application is fresh or saltwater, protein skimming offers tremendous benefits like increased dissolved oxygen levels in high bio density recirculating systems. Retail Tropical Fish Holding Systems – Saltwater retail fish holding systems require a constant high water quality level. Protein Skimming separates dissolved wastes before they mineralize, in turn reducing the load on the biofilter. Exhibits – Fish, reptile and mammal exhibits can benefit from protein skimming with improved water clarity.
