High-quality water treatment in hydroponic cultivation
Blomsterboda is one of the Nordic region’s largest producers of flowers and plants. The company has a constant focus on streamlining and increasing the quality of the entire production. So it was expected that the plant in Vallentuna north of Stockholm would stop cultivating bulbs and tulips in soil and switch to hydroponic cultivation.
Blomsterboda delivers full service of flower departments to grocery stores all over Sweden. The roots go back to 1912 when John Rydell started selling flowers from local commercial gardens at Kornhamnstorg in Stockholm. From the greenhouse in Vallentuna and together with local growers, flowers are sold to 550 grocery stores all over Sweden. The company is the largest in Sweden for bouquet binding and a large grower of tulips. Blomsterboda had sales of EUR 44 million in 2018.
When Blomsterboda switched to hydroponic cultivation they needed to find a solution to treat and disinfect the recirculation water. They also needed a way to add nutrients and limit the growth of bacteria, algae and othe unwanted substances in the water.
Along with the automatic addition of nutrients and chlorine, the automatic production and addition of ozone for water disinfection has freed up time for the staff. It is usually sufficient to supervise and to ensure that there are nutrients in the tanks.
This lead to a more reliable and efficient production with less chemical use and therefore reduced operational costs.
