There is no water condition we cannot treat. Review some of our more common applications below and call to learn how you can benefit from a customized water treatment system for your establishment.

Pre-Treatment Solutions

Preliminary treatment modules include multi-media filters, softeners, dealkalizers and chemical treatment, which allows water to perform more efficiently throughout your business. This is the first step to help reduce scale, extend the life of equipment down the line, reduce maintenance costs, and promote consistent production.


Culligan offers an advanced line of softeners to reduce the accumulation of harmful scale in equipment caused by iron, calcium, magnesium, and manganese ions. Softened water replaces those ions with sodium salts to improve efficiency of equipment without anti-scalant chemicals, resulting in both immediate and long-term cost reduction.


To provide complete filtration for any need or capacity, Culligan recommends filters to reduce turbidity from water, adsorb odors, neutralize acidity, and reduce heavy metals. Filtered water can reduce blowdown for substantial cost savings.

Dealkalizers & pH Adjustment

Culligan dealkalizers reduce unwanted anions in your water supply. By using an ion exchange process, dealkalizers reduce anions and may help reduce fuel and operating costs. Effective pre-treatment may utilize pH adjustment to help meet your equipment specifications.

Membrane Solutions

Membrane solutions can help reduce turbidity, suspended solids, dissolved solids, and organic substances. This step will help you increase the efficiency of your equipment and processes, resulting in substantial cost savings and reducing the need for chemical regenerants, in most cases.

Commercial Reverse Osmosis

Reverse osmosis is an advanced level of filtration, in which pressurized water passes through a semi-permeable membrane to separate dissolved substances from the water permeate. RO is the most effective barrier to salts, micro-contaminants, and organic substances such as viruses and bacteria, making it ideal for applications where high-purity water is needed.

Deionization Solutions

In this module, charged ion exchange resin reduces mineral ions from water. Deionization solutions include portable exchange deionization and automatic deionization. This module extends the lifespan of equipment, contributing to long-term cost savings.

Portable Exchange Deionization

Portable DI systems deliver a constant supply of quality water to operations large and small, without a capital investment. Regeneration or exchange is provided by Culligan of New York. This system reduces on-site labor and regenerant chemical handling.

Automatic Deionization

Premier Series DI offers automatic deionization and regeneration of depleted resins.

Storage Solutions

Storing purified water for peak instantaneous demand reduces capital costs and streamlines your production process. Storage tanks are available in a variety of materials and capacities for complete customization.

Standard tanks are FDA-regulated food grade. To completely customize your water treatment solution, tanks are available in various sizes, materials, and configurations.

Material Options: Cross-link polyethylene, High-density polyethylene, Reinforced fiberglass, Stainless steel
Shape Options: Conical bottom, flat bottom, dome top, vertical / horizontal orientation
Sizing Options: Standard sizes from 50 – 60,000 gallons, custom sizes

Distribution Solutions

Your business needs may at times require specific distribution solutions. Furthermore, polishing of water may be necessary based on final water quality requirements. Your Culligan Man will work with you to find the necessary pumps and disinfection technologies to provide you a complete solution.

  • Re-pressurization, recirculation and distribution
  • Sanitization
  • Disinfection – UV, Ozone, Chlorination, On-site Disinfection Generation Systems

Reclamation and Reuse Solutions

A complete solution must consider options for reducing water consumption through the reuse and repurposing of wastewater. Total plant water balance audits can help ensure your compliance with regulatory requirements and help you realize an improved ROI.

Salt Delivery

Leave the heavy lifting to your Culligan Man! A qualified team member will deliver the salt you need, when you need it, and with each delivery, he’ll perform a 10-point inspection of your softener.
