WASTEWATER FROM SHIPYARDS
Efficient Water Treatment of Wastewater Containing Heavy Metals at Hvide Sande Shipyard A/S
HVIDE SANDE Shipyard, Steel and Service has been a steady part of the shipbuilding industry since 1950. The company specializes in the repair and servicing of fishing vessels, older sailing ships, and schooners, as well as a large portion of the boats used in the wind industry.
They also offer new construction and servicing of houseboats. Every day, they face challenges in an industry that demands innovation and flexibility.


Hvide Sande Shipyard A/S Challenge
As part of the cleaning process of fishing vessels before painting, process water and wastewater containing heavy metals are generated. Previously, this water was disposed of, but HVIDE SANDE Shipyard sought a solution that could treat and reuse the water instead of continuing with continuous disposal.
They contacted ENVOTHERM, who tested a sample of the wastewater in their laboratory.
ENVOTHERMs Solution
ENVOTHERM delivered an ET150 wastewater treatment system with a capacity of 150 liters per hour, which effectively treats the wastewater and enables water reuse.
HVIDE SANDE Shipyard is very satisfied with the solution, especially the support they receive from ENVOTHERM, including hotline support. During the startup and commissioning of the system, it was a great advantage for the company to speak with the same engineer each time and quickly resolve any issues online or by phone.
With ENVOTHERM’s ET150 system, HVIDE SANDE Shipyard has achieved both an economical and practical solution that not only helps meet environmental requirements but also reduces disposal and promotes water reuse.
