Components
Water quality is the key to success in aquaculture, and by choosing the correct water treatment, you may increase the production capacity of the plant significantly. When the water quality is optimal, the fish stay in good health and production can be maximised accordingly.
For more than 30 years, Sterner has specialized in fabricating solutions for improving water quality, and Sterner has developed several unique products that ensure the right water quality for fish.
Effective degassing
CO2 removal from water is crucial for maintaining a water quality that fish need to thrive. Our in-house developed CO2 degassers have made it possible for many hatcheries to increase production without increasing the water consumption.
Our unique CO2 degassers holds a media that is not prone to growth by biofilm. This ensures optimal water quality and fish welfare. The degassers are easy to operate and require little maintenance.
Supersaturation of gases is a well-known problem in aquaculture, and is usually caused by water heating, pressure increases, pumps that suck false air or other factors. Sterner’s vacuum aerators are designed to alleviate supersaturation. Sterner makes the degassers in standard sizes in maintenance-friendly materials.
Our project engineers will assist in customising solutions tailored to your requirements.
Gentle particle removal with the right filter
Choosing the right filter is important for keeping good water quality, as well as for minimum of maintenance and operational smoothness.
Our mechanical filters are designed for high performance in aquaculture water treatment systems, where particle (suspended solids) shearing must be maintained at a minimum. Our filters are self-cleaning and require little maintenance.
Correct oxygenation contributes to optimal growth
Oxygenation is one of the most important parameters to have good control over in land based fish farming. The oxygen demand of the biomass is the single condition for the quantification of oxygen to be dosed to the system, with a direct relation between oxygen saturation and fish growth.
Sterner’s renowned OxyTech oxygenators provide oxygenation of the entire water course, directly to each tank. This allows the possibility of adjusting oxygenation for each tank as the demand changes over time.
Over 30 years, Sterner have installed several hundreds of OxyTechs and continually focus on optimisation of the technology.
We also deliver oxygen production through oxygen generators which can reduce oxygen costs by up to 50% when compared with the use of liquid oxygen. We also have emergency oxygenation and distribution systems as part of the OxyTech brand.
Disinfection of intake water
Effective disinfection of intake water is important and obligatory to prevent diseases from entering the plant.
The combination of good filtration and a correctly dimensioned disinfection system provides a safe solution against microorganisms. We deliver complete solutions based on ozone and UV, depending on the type of water and its use.
Our process engineers will serve you with a tailor-made solution, serving your needs in the best way.
Monitoring
To ensure that water quality is maintained at an optimum level, it is important to monitor key parameters in the water. Sterner offer a wide range of monitoring instrumentation and associated spare parts.
In our webshop, you will find an overview of the various measuring instruments and required spare parts for these.
