LiqTech membranes get drinking-water certification

The silicon carbide (SiC) membranes manufactured and marketed by Danish company LiqTech International Inc have been tested and certified by NSF International to NSF/ANSI Standard 61, which means they are now approved for usage in drinking water systems.

The NSF/ANSI 61 is a performance-based standard which ensures that components used in water treatment systems are not leaching any harmful substances (ie, metals such as lead, chemicals, toxins etc).

All of LiqTech's SiC membranes product offerings have successfully passed the toxicological testing required by the NSF. In addition, in order to receive this certification, LiqTech's production (facility) had successfully been audited by NSF.

LiqTech's SiC ceramic membranes can be used to replace sand filters, cartridge filters and traditional polymer/ceramic membranes. The potential for SiC membranes in the drinking water production is diverse and the benefits numerous.

Some applications are, but not limited to, groundwater with the removal of precipitated salts like iron, arsenic and manganese; surface water with the removal of organic suspended solids and humic acid; and seawater for prefiltration before reverse osmosis.
