Pretreatment Equipment and Consumables, Barnstead®

Use a Thermo Scientific® pretreatment option when the quality of your feed water doesn't match the requirements for your point of use water purification system.

• Ideal system to treat hard feed water
• Not only softens the water, but also protects the RO membrane from blockage
• Removes calcium, magnesium, iron, and manganese and a great variety of suspended matter and organic material
• Combination of multiple stages, from porous polymeric adsorbers to ion exchangers
• Necessary for feed water with a silt density index (SDI) that is greater than 3 or the total ionized solids (TIS) is greater than 250 ppm

• Easy-to-use pretreatment cartridge protects the RO membrane in a system against particles
• Ships with 10-inch filter housing and a 1 µm filter
• Ideal when feed water Silt Density Index (SDI) is 2-3

• Ships with two 10-inch filter housings, a combi-cartridge which contains a 5 µm filter and activated carbon, and a hardness stabilizer cartridge
• Removes chlorine, organics, and hard ions

• Ships with three 10 inch filter housings a combi-cartridge which contains a 5 µm filter and activated carbon, and a hardness stabilizer cartridge, and a 1 µm filter
• An effective triple pretreatment system removes chlorine, organics, hard ions, and particles larger than 1 µm
