We specialize in Water Treatment Products. RO Membranes

Siam Meditrade Co., Ltd.: We are one of the Marketing and Distribution Company for Medical Equipments in Thailand since 1994. More than 18 years of our establishment in Thailand, we have recently expanded our distribution lines for the water treatment products to serve both Medical & Industrial sectors.

RO Membranes

Our RO membranes are the produced from high quality elements which is applicable from light commercial use to drinking water industries. The RO membranes are checked to meet the set standard test level (high performance count) to ensure that customer will get both highest quality water and rejection rates.

The RO membranes technologies of the filtration system will remove large molecules and ions from the solutions that flows through to membranes stages. The results obtained is that the solute to retained on the pressurized side, and pure solvent to pass through the pores on the other side of the membrane elements to ensure high purification output. (Please refer to the specification and performances per attached data) And this is the reason why our selected RO membranes are the very consumable, economical plus cost effectiveness and mostly used with the water treatment filtration process.
