Good day,

We are a company in South-Africa who specializes in building Industrial water treatment and Process separation plants using membrane technology. We work across many industries but mostly specialize in mining applications. As such we have a need for Stainless steel 316L, Duplex Stainless Steel 2205 and Super Duplex Stainless Steel 2507 RO Membrane Housings. These Materials of Construction have been found to be the best selection as they don't corrode or react with the process stream

We would like a quote for the following RO Membrane Housings listed below:

1. Vessel size 1812
— Quantity 1 X 1812 (1.8'') in Stainless Steel 316L, 1 membrane per vessel, Pressure rating 1000 psi (69 bar)
2. Vessel size in 2540
— Quantity 2 X 2540 (2.5'') in Duplex Stainless Steel 2205, 1 membrane per vessel, pressure rating 1000 psi (69 bar)
3. Vessel size in 4040
— Quantity 8 X 4040 (4'') in Stainless Steel 316L, 6 membranes per vessel, pressure rating 1000 psi (69 bar)
— Quantity 25 X 4040 (4'') in Duplex Stainless Steel 2205, 6 membranes per vessel, pressure rating 1200 psi (83 bar)
— Quantity 25 X 4040 (4'') in Super Duplex Stainless Steel 2507, 6 membranes per vessel, pressure rating 1200 psi (83 bar)
— Quantity 18 X 4040 (4'') in Super Duplex Stainless Steel 2507, 4 membranes per vessel, pressure rating 1200 psi (83 bar)
4. Vessel size in 8040
— Quantity 12 X 8040 (8'') in Duplex Stainless Steel 2205, 6 membranes per vessel, pressure rating 1200 psi (83 bar)
— Quantity 20 X 8040 (8'') in Super Duplex Stainless Steel 2507, 6 membranes per vessel, pressure rating 1200 psi (83 bar)
— Quantity 6 X 4040 (8'') in Super Duplex Stainless Steel 2507, 4 membranes per vessel, pressure rating 1200 psi (83 bar)

The requirements we need for the Membrane Housings are to comply with the EU Standards (PED) and ISO Standards for pressure equipment. In all options, we prefer side ports on the vessels for feed and concentrate with Victaulic fittings. The feed and concentrate port should be at opposite ends of the vessel, with one at the top and one at the bottom for easy connection, if possible.

Please add in the quote the following information:
— Lead time for each item
— Proof of the manufacturers pressure vessel certification
— The Standard the vessels are manufactured to
— The total cost of the Membrane Housings
— The Delivery cost to Cape Town, South-Africa
