The Xiga technology is an unique and robust technology that provides maximum membrane footprint utilization. This enables inline operation and direct coupling with a downstream reverse osmosis (RO) system without an intermediate break tank.
The Xiga technology is a reliable and cost effective solution. Up to 4 ultrafiltration (UF) modules can be placed in one GRP housing. The largest Xiga unit has 4 columns of GRP housings which are stacked 12 housings high, holding 192 membrane elements in total. This incredibly compact design delivers a huge membrane area per square meter of floor space. In fact, Xiga provides the highest membrane area-to-footprint ratio in the market. Although Xiga is mainly used in big projects (> 10 MLD), the concept is also suitable for smaller plants. The smallest Xiga has 2 columns with 6 GRP housings, holding 48 membrane elements.
Xiga is developed for the treatment of surface water (to produce potable water or process water) and drinking water. It it also applicable for wastewater polishing and reuse. As pretreatment for seawater RO, it has a very impressive reference base. Xiga is also applied in industries such as Oil & Gas (injection water production).
As part of its separation into a new pure play water company, a new Pentair website has launched. Please visit the new Pentair.com to learn more about our exciting new company and your favorite brands!
