The hydRO PWRO systems are fully optimized pre-engineered RO based systems which are intended to deliver ultra pure water at the ideal quality to optimize power production applications and minimizing energy inefficiencies. Feeding the right quality of water to boiler make-up and rinse processes, reduces scaling and thereby increases the boiler cycles saving thermal energy as well as boiler process water. High efficiency turbines & high pressure boilers require consistent and reliable Ultra high purity water which DHT Power Water Treatment systems produce, problem free, day in and day out.
