In locations where seawater is abundant but drinking water is scarce, such as islands or on the coastlines of arid countries, the DOT turbine can help transform pressurized seawater into renewable fresh water through reverse osmosis. The seawater is pre-treated before being pressurized by the pump in the turbine. From there, the resulting high pressure water will be fed through a filtration & desalination system resulting in fresh water. The water can be used for industry purposes, irrigation, H2 production or drinking water.
The DOT reverse osmosis system consists of the DOT turbine and several standard sized containers combined with a Pelton generator. It is a standalone system that only needs access to seawater to produce fresh water. The output of the system can be switched easily between producing water or generating power at the same location.
Reverse osmosis research for Aruba
Design, construction and testing of a small scale wind driven seawater desalination plant. This project gave insight into the possibilities of integrating a DOT wind powered desalination concept in Aruba.
- Insight in control of a wind powered desalination system
- Theory of ERD-RO systems validated
Reverse osmosis pilot
Design, construction and testing of a 500kW wind powered electricity and seawater desalination plant.
- Control of a wind turbine via spear valve in combination with a SWRO membrane
- Proof of DOT wind powered desalination concept
- Insight in pre and post water treatment requirements
All our innovations are supported by an extensive track record of studies, prototypes and offshore testing. Our approach is to “put steel in the water”: relentlessly testing the concepts in its designated environment of operation.
