VEOLIA RO (H1) X 6 Pianta a osmosi inversa

VEOLIA RO (H1) X6 Reverse Osmosis plant
Formerly used for ethylene glycol recovery, with a 12 m3 raw water storage and homogenization tank, a nominal feed flow rate of 4 m3/h at 4 bar, and a filter backwash flow rate of 11 m3/h at 1.5 bar. Includes an automatic downflow multimedia filter with anthracite and sand beds on a gravel support, designed to remove suspended solids and protect the membranes.

Compact skid-mounted reverse osmosis unit featuring a dual-stage filtration system with replaceable 20 and 5-micron cartridges, a high-pressure pump with a variable speed drive, and a reverse osmosis module configured in two stages (1+1)x6, equipped with 8-inch DOW aromatic polyamide spiral-wound membranes installed in FRP pressure vessels rated up to 1,000 psi. Nominal recovery rate of 90 percent, equivalent to a theoretical production of approximately 3.6 m3/h of permeate under design conditions. Low and high-pressure piping and interconnections manufactured in AISI 316L stainless steel. Incorporates recirculation, front and side permeate collection, a CIP chemical cleaning and membrane flushing system, an FRP solution preparation tank, a 25-micron mesh microfilter, and a delivery pump for cleaning solutions and permeate water. Automation system based on a Siemens S7-200 PLC, with measurement and control of flow rates, temperature, pressures, pressure drops, operating times, pumping, backwashing, flushing, and process alarms. Operator panel with a 6-inch color touchscreen for parameter display, configuration, start, stop, filter washing, alarm consultation, and trend graphs. Includes a 2 m3 reverse osmosis reject tank for subsequent transfer to the evaporator. Serial No. MPP51525.
