Lubron Water Technologies’ specialists investigate which technique or combination of techniques will deliver the optimum solution for the specific circumstances. To do this, techniques such as filters and iron removal are employed. For demineralisation (removal of salts) of water, techniques including reverse osmosis are used.
Depending on the application, a dirt filter (filtering from 0.2 micron) or a side stream filter is used. Side stream filters are available rated from 1 µm to 50 µm. If necessary, magnetic inserts can be used to remove very fine magnetic particles. Lubron offers a wide range of side stream filters, with an operating capacity up to 50 m3/hour. We can design tailormade solutions for specific applications.

Iron and manganese can damage equipment and systems and are therefore often reduced to a minimum by treating the water. To remove iron and manganese from water, the source water is given intensive exposure to oxygen. After a series of subprocesses, passing through oxidation, hydrolysis, flocculation and precipitation, iron and manganese are eventually filtered out. In this process the divalent soluble forms of iron and manganese present in the water are converted into extremely poorly soluble forms. The iron and manganese particles resulting from this physical chemical process (also known as electrokinetic adsorption) can then be filtered out using calcined/heat-treated and sieved river sand, selected according the source of the water supply and the desired end result. The first precipitate formed, iron hydroxide, has a positive effect on the remaining formation of precipitate for both iron and manganese. Due to this catalytic action, clean filter sand must be given sufficient time to act before the iron removal process runs efficiently. The same principle applies for the manganese removal process. The ultimate quality of the water after iron removal (deferrised water) is dependent on various parameters such as the pH value (acidity) of the water, the oxygen concentration, the buffering capacity of the water source, the flow rate and the choice of filter medium.
Lubron has a wide range of standard units for iron and manganese removal, with a maximum hourly operating capacity of 80 m3/hour. Lubron’s specialists can provide tailormade advice on correct application of these. We always design units for higher volumes on a case-by-case basis.
