Industrial Services Inc. (ISI) products

ISI Water specializes in Seawater Reverse Osmosis (SWRO) technology. Our SWRO systems are capable of producing water suitable for drinking, irrigation, commercial, municipal, or industrial use. Regardless of your application, we offer SWRO systems tailored to your exact needs and ensure that the system runs properly once installed. When you work with us, we strive to provide a system that is exactly what you need, without unnecessary complications.

We offer Brackish Water Reverse Osmosis (BWRO) systems for water that is lower than seawater salinity and generally comes from an inland, underground source. We can provide reverse osmosis water treatment systems to serve industrial, commercial, or municipal purposes such as drinking or irrigation. These BWRO systems run at lower pressure than typical seawater RO plants and can be used for a variety of purposes such as the removal of heavy metals, chemicals, or minerals. We now even offer a variety of energy recovery solutions for clients interested in reducing energy costs.

Our nanofiltration systems use membranes to separate high charge molecules, chemicals, minerals, and organic matter from otherwise drinkable water. Nanofiltration does not reject many dissolved solids such as sodium and chloride, so it is well suited to areas where total dissolved solids are not a concern, but removal of larger contaminants is a must.  Some applications may include water softening, removal of bacteria and other organics, chemicals, or harmful metals. Nanofiltration systems offer lower energy consumption compared to brackish water RO (BWRO) systems, which greatly reduces operating costs.

Ultrafiltration (UF) is a common pretreatment process used to clean the feed water for reverse osmosis systems. These systems are capable of removing colloidal particles, viruses, bacteria, and suspended solids. UF systems require a Silt Density Index (SDI) less than 5.0, and ideally less than 3.0, for long term use. With UF filtrate SDI levels often reaching less than 1.0, UF is undoubtedly the best pretreatment system for RO.

The S and H series seawater reverse osmosis skids feature a FEDCO turbine energy recovery device. All ISI Water RO Skids are pre- assembled and ready for installation. Each skid includes all components required to operate and can be customized to  nclude any special requirements. There are many optional upgrades and accessory systems available for use with the RO skids (see www.ISI-Water.com). The product from the RO systems complies with World Health Organization (WHO) standards for potable water (
