The Hyde Marine BWTS is optimized for integration into a vessel's existing design and easily adapts to operating conditions. The system includes appropriate pretreatment to remove solids and large organisms. The Hyde GUARDIAN Gold's UV reactor kills or inactivates biological organisms including zooplankton, algae, bacteria, and pathogens from ballast water without affecting the normal operation of the ship and without using chemicals, toxins, or generated substances. Ballast water is treated again with UV light during discharge to ensure the maximum effect and ensure compliance.
