Are you talking about the refuse water from the RO? If you cannot discharge it, you could recycle it through a tank or basin and treat it with ultrasound. You would need about a week of residence time to cause the algae after treatment to naturally settle where it could be concentrated at the bottom and routed to a waste treatment facility.
To reduce the intake algae level, treat the supply reservoir. Our device can control a circular area of 120 acres (50 ha) for cyanobacteria and 17 acres (7 ha) for green algae and diatoms. It can also prevent biofilm formation in a zone of 60 meters from the device radially.
