Technical Specifications – Aquaculture Filtration Systems
1. General Requirements
The University of Southern Mississippi (USM) is soliciting sealed bids for the purchase and delivery of
aquaculture bead filtration systems and associated components for use in recirculating aquaculture
systems (RAS).
All equipment shall be new, unused, and of current production. Demonstration, refurbished, or prototype
units will not be accepted.
The specifications contained herein establish minimum acceptable standards for performance and quality.
Equipment offered shall meet or exceed all listed requirements. Equivalent products will be considered;

• Continuous operation in high-solids aquaculture environments
• Automatic or semi-automatic backwashing without interrupting system operation
• Minimizing water loss during cleaning cycles
All units must be suitable for both freshwater and marine applications and be compatible with existing
aquaculture infrastructure.
