SWT RO-500L (2/4040) - reverse osmosis unit with pump (up to 0.5 m3/h)

SWT RO-500L is a commercial reverse osmosis unit with a pump for 500 l/h of permeate. It is used for polishing treatment of domestic drinking water and natural water: it removes total mineralization, hardness salts, heavy metals, organic matter, bacteria, and viruses down to the required standards.

The second model in the SWT RO range: twice the capacity of RO-250L with the same 1.1 kW pump and the same BB10 cartridge — the gain comes from a second 4040 membrane housing. It also differs from the smaller model in size: 610×585×1630 mm (±50) is the standard dimension for the series, whereas RO-250L is built in a smaller 490×480×1600 mm. The next model in the range, RO-750L, already requires a 1.5 kW pump, so RO-500L is the capacity limit on the weakest drive in the series.

Raw water flow rate — 820 l/h in production mode and 1750 l/h during hydraulic flush: the flush circuit is the same as for RO-250L. Typical conversion rate on fresh groundwater and surface water is from 60% to 75% (permeate : concentrate from 3:2 to 3:1). Raw water inlet and concentrate outlet — G¾", permeate outlet — G½"; the G½" CIP wash inlet and outlet lines serve reagent membrane washing.
