PRE-FILTRATION

IMPROVE YOUR RO OPERATION!

It is well-known that the performance of a RO system highly depends on the quality of the pre-filtration. This is due to the following facts:

• Improved pre-filtration in terms of more efficient removal of suspended solids results in longer operating intervals of the RO system before the need of chemical cleaning. The reduced number of chemical cleaning cycles means prolonged lifetime for the RO membranes and reduced operating costs.

• Efficient removal of suspended solids, results in reduced fouling of the RO membranes. This reducesconcentration polarization which again improves the quality of the RO permeate. An increase of the RO capacity is often seen when improving the pre-filtration step.


SiC MEMBRANES – THE HIGH PERFORMANCE AND ROBUST MEMBRANE ALTERNATIVE TO SAND FILTERS AND POLYMERIC MEMBRANES.

The robust SiC membranes are ideal in scenarios with bio fouling potential, since the SiC membranes can be cleaned with any chemicals (pH 0-14), strong oxidizers (e.g. ozone) and have a high mechanical strength which enables high pressure back flush. The temperature resistance is an operational advantage to assure both efficient cleaning and to assure membrane selectivity (integrity) at higher temperatures.

FEED CONTAINING OIL? - NO PROBLEM!

The SiC membranes can handle high oil concentrations (+100,000 ppm oil).


REDUCE YOUR CONSTRUCTION COSTS!

The high flux potential of SiC is achieved due to the high porosity of the individual layers, low contact angle to water and large pore sizes insupport/carrier.

High flux rates lead to compact membrane installations and reduced installations costs, i.e.
reduced number of pipes, valves, instruments and building square meters.
