How does Deionization (DI) work?
Deionization (DI) is a water treatment technology used to remove ions and impurities from a liquid stream to produce ultra-pure water. This highly specialized technology is successfully applied using membranes or resin exchange systems, or a combination of the two. We design multi-pass membrane or resin exchange systems for most industrial applications.
Membrane based DI has the advantage of reliable mechanical rejection which ensures more comprehensive removal of contaminants whilst negating the need for chemicals and hazardous waste disposal. Resin based systems are highly selective and well-suited for further polishing.
Benefits of Deionization (DI) for water treatment
01
Contaminant Removal
DI effectively removes ions and impurities from water, including cations (e.g. Ca & Mg) & anions (e.g. Cl and SO₄²-).
03
Purification
DI efficiently produces high purity, low conductivity water suited to laboratories, pharmaceutical manufacturing, and electronics industries.
05
Sustainability
Membrane-based DI is more environmentally friendly than traditional ion exchange due to reduced chemical use and waste production.
02
Scale Prevention
It helps prevent mineral scale buildup in pipes and equipment, extending their lifespan.
04
Cost Savings
Membrane based DI reduces the need for chemicals and improves maintenance intervals leading to long term savings.
06
Versatility
Can be used with a variety of sources and combined with other treatment methods for a tailored purification approach.
Maintenance and servicing of Deionization systems
The service and maintenance of DI systems vary depending on the technology selected. Traditional resin based systems may require regular chemical top-ups, resin recharging, and resin replacement. Additionally, water quality must be continuously monitored to ensure optimal performance of the resin.
Membrane based DI systems require less frequent maintenance, but membrane pressures must be monitored along with system performance. Additionally, membrane cleaning cycles and servicing of other plant components may be needed to keep the system running efficiently.
Cost of installing a Deionization system
DI system costs vary widely depending on the technology chosen, system capacity, water quality required (e.g. Type II Grade), additional features, and site specific requirements. Typically membrane based systems prove higher in CapEx, but lower in OpEx.
