How to Size a Pond Aerator by the Number of Diffusers

Every pond is unique in size, shape, and depth. 

Figuring out the number of diffusers needed to mix the entirety of the pond and working backwards can be a prudent strategy. For example, if you have a kidney shaped pond, you probably need at least 3 diffusers. Some ponds may need 4 if they have multiple coves.

Pond Aerator Sizing Steps:

1. Choose the number of diffusers based on the shape and size of your pond.
2. Identify which model diffuser you are going to buy. Manufacturers typically publish how much air flow is needed to “self-clean” – the amount of air flow that will keep the pores open and free of biological growth. Somewhere in the 30-40 LPM (liter per minute) is common and creates good circulation.
3. Figure out the back pressure of your system (water pressure + diffuser backpressure + tubing friction loss). For a detailed step-by-step process, check out our article: https://www.hiblow-usa.com/2022/06/07/pond-aerator-how-to-calculate-backpressure/
4. Once you have figured out the backpressure of the system, review the pond aerator performance curves to determine the total amount of air flow. Start with the aerator recommended in the Pond Aerator Sizing Recommendation Table and bump up to the next size if needed. Pressure and flow have an inverse relationship – if one goes up, the other goes down. Performance curves are available on our website and are explained in the backpressure article.
5. Divide the number of diffusers needed by the total air flow. Choose the pump that exceeds the amount of flow per diffuser suggested by the manufacturer.

What Size Aerator Should You Buy?

Subsurface aeration is the best way to mechanically initiate the transfer of oxygen into a pond. Although micro bubbles – created by air flowing through a diffuser – add some dissolved oxygen, the greatest transfer occurs as water circulates to the surface. Water at the surface absorbs oxygen from the atmosphere and then circulates back to the bottom of the pond. Turning over the pond – the process of moving the entire volume of water to the surface periodically – creates an oxygen rich environment at all depths. In turn, fish can thrive, and conditions are right to break down organic matter and reduce/ prevent algae blooms.

Given the importance of water circulation, choosing the right size pond aerator is critical for getting the best results.

 Need help? We recommend two methods for choosing the right pond aerator - using our pond sizing recommendations chart, and sizing your aerator by the number of diffusers.

Aquaculture America – San Antonio, Texas – Feb 18-21, 2024

Come see us to discuss your aeration needs!

The Aquaculture America 2024 conference includes the largest tradeshow in the Western hemisphere for the aquaculture industry. Stop by our booth #805 and check out our HP, XP, and WG series air pumps. Whether you are aerating single tanks or larger ponds, our air pumps and manifold systems are a durable, energy efficient, and quiet option. Every air pump we manufacture is oil and lubrication free, so no worries of contaminating your water. We engineer and build our pumps for continuous duty operation, and they are approved for installation outdoors. You and your fish can depend on the reliability of HIBLOW linear air pumps.

Septic-Con 2024: Tacoma, WA | HIBLOW USA

HIBLOW USA is excited to exhibit and meet with current customers, wholesalers, and service providers at Septic-Con in Tacoma, WA! If you have questions about our linear air pumps—stop by our booth to talk with us.

SEPTIC-CON is the Western United States largest trade show and conference for the On-Site Septic Construction, Installation, Operations & Maintenance, Pumper and Design industries and consumes the entire Greater Tacoma Convention Center for two full days.

Dual Port Septic Air Pumps

HIBLOW manufactures Dual Port septic air pumps designed for aerobic treatment unit manufacturers.  The Dual port includes a timer that prompts the switch in air flow from the “MAIN” outlet port – used to aerate the main aeration chamber – to the second “SKIM” or “Backwash" port used for a secondary operation. Commonly, this secondary operation acts as an airlift or suction pump to move effluent, sludge, or scum from one section of the tank to another. Only one outlet port can operate at a time, both outlets cannot operate simultaneously.

HIBLOW manufactures two models: the DUO Series (DUO-50, DUO-60, DUO-80) and the Dual Series (HP-50W, HP-60W, HP-80W).  When purchasing a replacement air pump, it is critical for the timer settings to match that of your manufacturer’s system.  

Working with your local aerobic treatment service provider with knowledge of your system or contacting the OEM directly is essential to ensure your system has the correct timer settings and operates as it is designed.

HIBLOW Provides Linear Air Pumps for Residential and Commercial Wastewater Systems

In many onsite treatment systems, the air pump is the only moving part in the overall septic system, so it must be dependable. Working 24 hours a day and through all four seasons of the year — HIBLOW linear air pumps set the industry standard for reliability and service life. Additionally, most Aerobic Treatment Unit (ATU) manufacturers supply HIBLOW linear air pumps with their onsite wastewater treatment systems.

We design, engineer, and manufacture all HIBLOW linear air pumps in our own facilities. We don’t buy pumps from other companies and re-brand them, and we don’t use contract manufacturers. Every HIBLOW linear air pump is fully tested and certified for quality in your application before it is packaged and shipped to you from one of our factories.

HIBLOW DUO/DUAL Port Air Pump Timer Settings

HIBLOW manufactures Dual Port septic air pumps designed for aerobic treatment unit manufacturers.  The Dual port includes a timer that prompts the switch in air flow from the “MAIN” outlet port – used to aerate the main aeration chamber – to the second “SKIM” or “Backwash" port used for a secondary operation. Commonly, this secondary operation acts as an airlift or suction pump to move effluent, sludge, or scum from one section of the tank to another. Only one outlet port can operate at a time, both outlets cannot operate simultaneously.

Each Aerobic Treatment Unit manufacturer has specific and proprietary timer settings.  Their systems have gone through extensive testing to receive certifications from a third-party lab to meet regulatory requirements at state and local levels.  Any change to the timer settings could impact the effectiveness of the system and the quality of the effluent that enters the drain field. Standard single port air pumps should also not be used as a replacement for Dual Port models.
