We supply complete land-based aquaculture systems, including RAS, and work closely with our customers throughout the process, from needs analysis to finished installation and commissioning
Complete land-based facilities
We design and build land-based fish farms for salmon and other fish species. From fry to smolt or grow-out. Our solutions are designed to meet the highest standards of quality and performance. We take into account all aspects of the plant, including water treatment, fish welfare and energy efficiency. Our goal is to deliver facilities that are both sustainable and economically profitable, and we work closely with our customers to achieve this.
Our experienced team of engineers and project managers support customers throughout the design phase, from concept development to detail engineering. We ensure that every part of the project is carefully planned and adapted to the wishes and needs of the client.
Our help ensures that the project is carried out efficiently and with high quality.
RAS Facilities
We specialize in the delivery of complete RASfacilities, which are designed to optimize water quality and minimize environmental impact. Our RAS facilities are built to ensure high production efficiency and reliability, with a focus on sustainability and cost-effective operations. We offer everything from design and engineering to installation and commissioning, and we are with the customer throughout the process to ensure a successful outcome.
Water treatment
The fish should thrive in an aquatic environment that throughout the production cycle is affected by nutrient turnover. Waste substances from fish are removed from the system using various processes in the RAS department. In this way, the water supplied to the production units is kept fresh and the need for new water from the environment is reduced. With reduced water demand, there is also less need for energy for heating the production water. A RAS solution ensures stable water quality with reduced resource use.
RAS Processes
We tailor our facilities to the customer's wishes. Basic need is good handling of particles from feed turnover. With gentle filtration, the waste can be further utilized as a nutrient for circular energy production.
The heart of the RAS facility is the biofilter where specialized bacterial cultures handle waste products from the fish's digestion. Water saturated with carbon dioxide from the fish's exhalation is handled in aeration systems, and fresh oxygen is supplied to the purified water before returning it to the production units.
Filtration and gas removal can be further complemented by use of processes that deal with demanding microorganisms and fine particulate wastes, such as UV treatment and oxidation methods consisting of ozone or AOT.
Engineered Solutions
VAQ AS offers design assistance to our customers for projects of all sizes. It involves extensive complete fish farms, but also partial processes and simple installations. These can be systems for intake purification, sludge treatment or optimization of existing systems. The solutions or sub-components are adapted, installed and commissioned at the customer's premises.
Components, service and maintenance
We offer a comprehensive range of components, including standard products and spare parts, to ensure your facility always has the necessary parts for reliable operation and maintenance. To ensure longevity and optimal performance, we offer a range of services, including maintenance support, service agreements, assembly, repairs and general maintenance.
We also assist with operational monitoring and optimization to ensure that your facility operates as efficiently as possible.
Our goal is to ensure long-term operation and satisfied customers through continuous support and follow-up.
Training
We offer thorough training in the operation of the RAS processes during the start-up of the facilities, so that our customers are given a confident daily work life with fish in focus.
