The Xiga solution 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.

With carefully selected partners, Pentair develops innovative and ready-to-use membrane installations that meet both regulatory and financial KPIs. The Pentair scope consists of the modular Xiga solution, X-Flow membrane elements, engineering, commissioning and process optimization.
As one of the world’s foremost membrane technology knowledge centers, we share our scientific know-how and practical experience with our partners to make the difference in challenging filtration projects. 

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).
