Culligan® High-Purity Water Advantages |
N/A
No Capital Investment You rent instead of buy and conserve your capital. Rental fees are part of your operating costs, spread out over the time you use the service. Rental charges can be arranged to suit your needs - per tank, per gallon, or per regeneration. Reduce Labor and Maintenance Costs There is no equipment to operate, repair and no equipment downtime. Your local Culligan® dealer installs and maintains the equipment. System regenerations are handled off site by a Culligan® regeneration facility. Your personnel do not need to handle chemicals, dispose of any waste or perform any routine maintenance or service work. Culligan® Global Network - Global Scope, Local Service and Knowledge With over 800 plus dealers and international licensees in over 90 countries, your local Culligan® dealer can provide quick, professional and efficient services and knowledge to address your water treatment requirements.

High-Purity Water System from a Single Tank to a Complete Solution |
N/A Culligan® PEDI High-Purity water systems are available in several system configurations. Your system is customized for size, capacity, system configuration to help meet your water quality and quantity needs in the most efficient and economical operation. |
Two-Bed Portable Exchange Deionizer (PEDI) System |
N/A This is a typical Ion Exchange DI System where the Cation and Anion Exchangers are connected in series as two separate columns. The Cation column/tank reduces positively charged ions (calcium, sodium, magnesium, potassium, iron, etc). The Anion column/tank reduces negatively charged ions (sulfates, chlorides, carbonates, bicarbonates, nitrate and silica). Strong Base Anion units typically produce deionized water with quality of <0.5 megaohms-cm at a pH of 8-9. Weak Base Anion units produce lower quality water (50 kohms-cm nominal), at pH of 6-7, and do not remove silica and CO2. |

Mixed-Bed Portable Exchange Deionizer (PEDI) System |
N/A Cation and Anion resins are combined typically in a 40/60 by volume proportion and mixed in a single column/tank. Mixed Bed Deionizers are used in the production of High-Purity water of >2 megohms-cm resistivity with a more neutral pH than two-bed systems. Typical installation includes two columns in series (worker - polisher) to provide continuous High-Purity water and back up contingency. Mixed Bed PEDI is used with tap water or as polishing systems downstream from RO water purifiers for the production of ultrapure water of >10 megohms-cm. Up to 18.2 megaohms-cm ultrapure water can be produced. |
Multiple-Tank Portable Exchange Deionizer (PEDI) Systems |
N/A Three tanks or more are connected in series or parallel or a combination of the two. Produces High-Purity water in any desired quantity. Systems typically consist of a Strong Acid Cation (SAC) column, a Strong Base Anion (SBA) and a Mixed Bed (MB) Polisher column in a number of varying combinations to produce the water quality and quantity required. High-purity water quality of >15 Megaohms-cm, with a more neutral pH can be attained. |
