AquaDisk Filters – Frequently Asked Questions

AquaAerobic AquaDisk Filter
Aqua-Aerobic AquaDisk® Tertiary Filtration

What Sets the AquaDisk Filters Apart?

The AquaDisk Filters are ideal for tertiary filtration due to their proven removal efficiencies and high-quality effluent. The thick cloth media maximizes solids removal for effective filtration. Additionally, automatic backwashing cleans the cloth media, allowing for continuous filtration even during backwashing. Vertically installed disks reduce the footprint and maximize filtration surface area for higher throughputs. Manufactured by Aqua-Aerobic Systems in Rockford, IL, the AquaDisk filters are California Title 22 Certified for Water Reuse Standards, delivering high-quality effluent for water reuse.

What Wastewater Applications Can Benefit from the AquaDisk®?

The AquaDisk® treats municipal and industrial wastewaters for tertiary treatment, BOD & suspended solids removal, phosphorus removal, color removal, and water reuse/recycling. A variation of the AquaDisk® called the AquaStorm® is ideal for wet weather applications, and the AquaPrime® for replacing primary clarifiers.

Why Use an AquaDisk® Filter?

In wastewater plants where secondary treatment falls short of meeting stringent effluent criteria, tertiary filters become imperative. AquaDisk® filter offers many advantages over traditional sand filters and other tertiary filters:

  • Achieves higher quality effluent with low TSS, NTU, and phosphorus levels
  • Offers higher loading rates and lower backwash rates
  • Low headloss
  • Minimal maintenance
  • Small footprint with significant space-saving advantages
  • Expandable and easy to retrofit
  • Equipped with fully automatic PLC control system
  • Low cost of ownership
  • Available with a variety of different cloth types and in packaged configuration

How Much Wastewater Can the AquaDisk Filter Process?

Each disk is two meters in diameter and can process up to 500,000 gallons of wastewater daily. You can install up to 24 disks in the AquaDisk® filter. Smaller applications use the Aqua MiniDisk®, while larger facilities utilize the Aqua MegaDisk®.

What Are the Operator Requirements?

The AquaDisk® Filter requires very little operator attention. The filter should be inspected daily and should take about 30 minutes per week.

Is Pilot Testing Available?

Absolutely, pilot test trailers are readily available. While most applications do not require pilot testing, it can be crucial when selecting and optimizing filtration equipment for unique wastewaters. This process confirms that the AquaDisk filter will work seamlessly with specific wastewater conditions, providing valuable data on the expected hydraulic throughput, performance, backwash frequency, or the need for filter aids.

Where are AquaDisk® Filters Manufactured?

The AquaDisk® Filters are built in Rockford, IL and they meet all Made in the USA requirements.

How Many AquaDisk® Filters are Installed?

Over 1,000 AquaDisk filters are installed in North America and more than 2,000 worldwide.

Is Maintenance Required?

The AquaDisk filter has one main wear component; the cloth media. Depending on the type of wastewater, hydraulic loading rates, solids loading rates, and backwash rates, the cloth media typically lasts five to seven years. The backwash frequency increases as the cloth media wears, and the filter performance declines. Two men can install replacement media in 1 day for a 1 MGD filter with four disks.
