Aquacare Environment Inc
About
Founded in 1987 by Henning Gatz and headquartered in Bellingham, Washington, Aquacare Environment Inc is a manufacturer and integrator of recirculating aquaculture system (RAS) equipment for commercial-scale land-based fish farming worldwide. The company designs, supplies, and supports complete aquaculture installations from individual components to turnkey facilities, emphasizing modular prefabricated design that ships economically and assembles with local labor under Aquacare supervision. Their tank line includes glass-fused-to-steel bolt-together circular tanks for freshwater and epoxy-coated steel tanks for marine environments, both designed for efficient solids transfer. Primary solids removal uses stainless steel or duplex drum microscreen filters, with standalone and in-sump foam fractionators handling fine particulates. Aquacare offers five distinct biofilter technologies: Moving Bed Biofilm Reactors (MBBR) using 500-2,500 m2/m3 polyethylene media, static media biofilters, trickle filters, micropore biofilters integrating CO2 stripping with nitrification, and denitrifying filters with ORP-sensor-controlled automated carbon dosing. The Oxyflow oxygenation system dissolves 1.0 to 60.0 kg of oxygen per hour at over 95% efficiency using a design by French engineer Bohumil Sevic. Additional product lines include forced-air CO2 stripping columns, radial flow separators achieving 90% settleable solids removal, the Watropur press-dryer converting 2% inlet solids to 90% dry output, pneumatic Fish Farm Feeder systems from Galicia, Spain, and custom SCADA monitoring packages. Notable installations include Dunn's Market Fish in Arkansas and Tsar Nicoulai Caviar in California.
Key Products
Modular bolt-together circular tanks for freshwater aquaculture with corrosion-resistant glass-fused-to-steel construction for long service life.
Marine-grade circular tanks with epoxy coating for saltwater aquaculture applications.
First-line solids removal equipment available in stainless steel or duplex models depending on salinity, providing robust and reliable mechanical filtration.
Self-scouring biofilm reactors using polyethylene media (500-2500 m2/m3 surface area) with correctly sized aeration grids and retention screens for continuous nitrification.
Biofilters that trap fine solids and perform nitrification simultaneously, requiring periodic backwashing for maintenance.
Passive biofilters with or without countercurrent airflow, often combined with CO2 stripping for dual-function treatment.
Biofilters using polyethylene micropore disk media that integrate CO2 stripping with biological nitrification in a single unit.
Anaerobic biofilters where heterotrophic bacteria reduce nitrate to nitrogen gas, with automated carbon dosing controlled by ORP sensor feedback.
High-efficiency oxygen dissolution system dissolving 1.0 to 60.0 kg oxygen per hour at over 95% efficiency, designed by French engineer Bohumil Sevic.
Forced-air stripping columns using structural plastic media for high air-to-water surface area, paired with efficient low-head turbine pumps for scalable and cost-effective CO2 removal.
Solids removal unit achieving 90% efficiency for settleable particles with sinking speeds of 8 cm/min or greater, available in five prefabricated models.
Standalone or custom low-head in-sump fine solids removal systems for removing micro-particulates and dissolved organics from aquaculture water.
Press-dryer system converting 2% inlet dry matter to 90% outlet solids, handling 0.25-12 tonnes/day dried solids using only 0.33 kWh/kg separated water.
In-ground ecological system using progressive cells to capture solids and break down dissolved nutrients (N and P), producing reusable treated water.
Customized real-time monitoring, alarm, and control systems for critical water parameters and equipment status in aquaculture facilities.
Computer-controlled pneumatic feeders delivering precise doses frequently to each tank population, maintaining balanced biofilter load and optimizing feed conversion.
Complete hatchery equipment including broodstock tanks, larval tanks, rotifer/artemia/algae production systems, egg disinfection, LED lighting, and dosing systems.
Low-head pumping systems designed for RAS where water is pumped once after solids removal and biofiltration, before oxygen enrichment.
