Filtration
A two-stage approach to filtration – mechanical and biological – ensures fish health and helps maximize production. Innovasea can provide individual components or a complete equipment solution.
A healthy, productive land-based operation needs both mechanical and biological filtration systems – mechanical filters to remove larger waste particles and biological filtration systems to convert ammonia to harmless compounds. When used together, mechanical and biological filtration systems result in healthier fish and increased production.
Mechanical filtration
It is crucial to remove solids from a recirculating aquaculture system as quickly as possible to prevent breakdown and poor water quality. Mechanical filters are either gravity fed or pressurized and help remove different solid sizes from fish culture systems. In addition to drum filters, we offer:
- Radial Flow Settlers: These are the preferred settling devices for intake water, RAS and effluent treatment applications. Radial flow settlers are gravity flow fiberglass vessels that can be plumbed at different key locations within a system.
- Beadfilters: These are pressurized vessels where water is cleaned by pushing it through small plastic beads. Backwash of the beadfilter can be done using a small air blower to minimize water usage.
- Protein Skimmers: Also called foam fractionators, protein skimmers are a great way to filter out extra fine solids. They work great in saltwater application and with ozonated systems.
- Sandfilters: These are pressurized vessels that push water through sand for a fine filtration down to 20 microns.
Biological filtration
Our biological filter is a moving bed biofilter system that uses MB3 media, which is manufactured in the United States and proven in freshwater and saltwater applications.
This advanced media, which can last more than 12 years, is made from durable, bacteria-friendly, virgin polyethylene with a self-cleaning outer surface and a protected inner surface. It enables the nitrification cycle to take place in the RAS, reducing toxic ammonia and nitrite to a less toxic form, nitrate. The moving bed biomedia needs to be aerated so the MB3 media gently tumbles around.
Innovasea can determine the volume of biomedia needed for your RAS based on fish species, water temperature, salinity, feed load and protein content.
