The ROTEC, or Reverse Osmosis System, is designed to be extremely compact while allowing a convenient operating space and perfect usability. ROTEC is developed applying the modular approach, therefore combining pre-wired modules so that customer will get the best option for their needs. The modules pickable are pre-treatment module, sanitation, UV system, cleaning, EDI.

Feed water is micro-filtered and loaded into the feed tank; then it is pushed by the high-pressure booster pump to the first stage of reverse osmosis, through the micro-filtration and temperature control system. From the first stage, concentrate is partly discharged and the rest recirculates in the feed tank, while permeate is sent to the high-pressure pump of the second stage; this is repeated in all stages. The purified water produced is sent to the storage tank and then distributed to the POUs.

ROTEC 20.000 HWS is built on skid, designed to be a stand-alone unit, assembled and wired in the workshop, yet immediately operational at customer site. The PW generator has 20.000 l/h capacity, it is a double pass reverse osmosis system with UV lamp for debacterialization; operating temperature is 15° < T < 20°C and sanitization temperature is 85°C.

The system is composed of one 1.000 L buffer tank, high pressure pump, temperature control module, reverse osmosis (first and second pass), degassing station with caustic soda dosage, UV lamp, electric panel and PLC control.

The control system is based on PLC/HMI solution, with one remote I/O module. The HMI interface allows to supervision system status, manage and monitor automatic production, manage multiple user accounts/groups, monitor and manage alarms, view real-time and stored data and more.
