Deionizers, demineralizers and DI systems are different names for the same equipment. Deionization or demineralization is a process to remove ions, minerals and some gases from water. The deionization process removes ions, dissolved solids, gases, and cations and anions including:
Our DI water equipment comes in various sizes and can be configured to meet any flow rate or quality specification, no matter how demanding.
The most common deionizer process uses specially manufactured ion exchange resins to remove the mineral salts from water by exchanging the ions on the resin with the unwanted ions in your water to be treated. Deionization produces high-purity water that is generally similar to distilled water. Nalco Pretreatment Solutions (PTS) provides deionization solutions ranging from under-the-sink tanks to trailers.
Another process, electrodeionization (EDI), utilizes ion exchange resins and electricity to produce ultra pure deionized water. EDI is a continuous and chemical-free process of removing ionized and ionizable species from water using DC power. Nalco PTS can work with you to design an EDI system to meet your needs.
Nalco PTS is a leading manufacturer of industrial water demineralizer and deionizer (DI) equipment designed for the economical and efficient removal of dissolved salts and minerals. As required water quality increases, recirculation skids with quality monitors, UV units and sub-micron filtration are required.
This option is perfect for customers who have: zero-discharge plants, other environmental limitations and cannot handle on-site regeneration. Also, if you have temporary applications such as power peaking stations that operate for short periods of time or as a temporary replacement during repair of an in-house system, offsite regenerated DI tanks will make sense.
Onsite Regenerated Customer Owned
Nalco PTS designs, manufactures, and services industrial water demineralizer and deionizer (DI) equipment designed for the economical and efficient removal of dissolved salts and minerals.
You will need the permits to discharge regenerant waste and the training to handle concentrated acid and caustic regeneration at your plant.
Nalco PTS has two-bed deionizers for industrial applications designed for full- or semi-automatic production of water with a conductivity of less than 10 micro-ohms and feature:
Nalco PTS can supply portable service DI water systems for high purity and ultra high purity water applications for virtually any process industry where deionized water is critical to production. The flow rate through individual banks of deionized water tanks ranges from 1 gpm to 150 gpm. Depending upon the flow requirement, single or multiple banks are used.
Service Deionized Water allows companies to concentrate on their core business and maximize profitability. Most importantly this option eliminates on site chemical handling and hazardous waste neutralization. Companies requiring a supply of deionized water for their process water or boiler feed water needs are choosing to outsource their high purity deionized water requirements from a service company.
Known in the water treatment industry as service deionization (SDI), this procurement option provides high purity deionized water users with a cost effective alternative to the difficult issues associated with owning and operating regenerable deionizers or demineralizers. Renting portable deionized water systems eliminates:
Renting DI water systems also provide a consistent supply of high purity deionized water employing standard designs and proven ion exchange technology. Portable deionized water systems are particularly attractive when there is a temporary need for high purity deionized water or an ongoing need that is expected to change over time.
Nalco PTS offers two options to produce deionized water with the quality you require. We have a DI service exchange service option and a DI capital equipment option.
Nalco PTS can supply portable service DI water systems for high purity and ultra high purity water applications for virtually any process industry where deionized water is critical to production. The flow rate through individual banks of deionized water tanks ranges from 1-150 gpm. Depending upon the flow requirement, single or multiple banks are used.
