Industrial Water Treatment Applications
Raw Water Pre-Treatment
Wherever your raw water comes from; Well, borehole, surface water, river water, sea water, recycled waste streams or potable water from the municipal supply, good pre-treatment is essential to protect your downstream processes and save costs.
Raw water often contains a wide range of water contaminants such as suspended solids, organics, hardness, heavy metals such as manganese, iron, lead and arsenic. All of which must be removed or reduced before introducing the water into your processes.
Culligan offers a number of technologies designed specifically to treat raw rater including media filtration, ultrafiltration, reverse osmosis, chemical dosing and disinfection systems.

Physical Water Conditioners Ultrafiltration
Available in 2 models, ClearScale andClearScale Plus, Culligan UK’s WRAS range of physical water conditioners can prevent or reduce the formation of hard (lime) scale by use of magnetic fields. By using magnetic rather than electromagnetic fields a power source is not required.
The Clearscale Plus range of physical water conditioners possess a two stage magnetic and catalytic treatment system.
Ultrafiltration (UF) is a process of separation under pressure, able to separate insoluble particles form the water.
Ultrafiltration systems are ideal for Ground water and surface water treatment, as well as Seawater desalination pretreatment applications.
Culligan uses robust outside-in PVDF fiber technology hollow fiber membranes benefit that provide high clean-ability, low chemical consumption, high recovery, and a superior combination of mechanical properties and chemical resistance.
Deionization – Ion Exchange Water Treatment Systems
Continuous Electro-deionization (CEDI)
CEDI process reduces ions from water using electricity, resin and membranes, decreasing the need for chemicals. CEDI is used as a polishing process to further deionise Reverse Osmosis permeate to multi megaohm-cm quality water. Models are available for up to 13m3/hr flow rate.
Fully automated demineralisation units designed for flows up to 40m3/hr. Choose from a flexible configuration of weak base or strong base resin tanks. Deyolit series deionizers are equiped with a control system designed to monitor the process & automatically initiate regeneration when water quality deteriorates to a pre-determined limit.
Portable Exchange Deionizers (PEDI)
For installations where regeneration systems are not appropriate, replaceable portable exchange deionisers (PEDI) are an great solution. Suitable for a wide range of flow rates (up to 500 L/hr), Culligan PEDI systems reduce both positively and negatively charged ions from water by means of ion exchange resins. When your PEDI tanks are exhausted, a Culligan service technician can replace your ion exchange tanks at your convenience. This type of system can reduce capital costs as well as handling of regenerate chemicals such as caustic and acids.
Medical & Pharmaceutical Reverse Osmosis
The SDS (Single Dialysis System) produces up to 80 l/h of reverse osmosis quality water for use in haemodialysis. The unit is ideal for applications such as dialysis in a patient’s home, use by emergency services, dialysis in acute cases and for transplant patients. Designed to be compact and easy to use, the equipment is on wheels to aid with mobility.
RO2 Dialysis RO
For flows of up to 3600 l/h, the RO2 Bi-Osmosis system is ideal for treating water for whole-ward haemoldialysis applications. Water passes through 2 reverse osmosis systems to produce the highest quality water, but in the unlikely event of a problem the system will automatically move to single pass treatment thereby ensuring patient safety at all times
Pharma RO System
The PHARMA unit utilises reverse osmosis and demineralisation technologies to produce up to 160 L/hr of ultrapure water. Designed to satisfy the most demanding pharmaceutical type applications, the pharma water treatment unit is an ideal choice for industries requiring reliable ultra-pure water production.
Ideal for fast installations in areas with limited space, the Dual Box system includes pre-treatment and a PLC controlled RO2 Bi-osmosis system within a satin-finish steel enclosure.

There are more ways to disinfect your pool water than you may realize:
Chlorine & Bromine disinfection
the widest known and most common solution to pool water disinfection. Chlorine and bromine is extremely effective at killing microorganisms, but needs careful control. All Culligan chlorine treatment systems are designed with ease of use and safety of the pool user in mind.
is a technology that is growing in popularity, particularly in competition pools for swimming athletes. Ozone uses oxygen atoms to destroy microorganisms through oxidation. Ozone has a number of advantages over traditional chlorine and bromine based disinfection systems. Ozone not only disinfects the water it also leaves pool water clear of the chemical residue that can cause haze in the water, chemical odors, and can cause skin and eye irritation.
By utilizing UV light wavelengths bacteria are deactivated and rendered harmless. This type of technology shares many of the benefits of ozone systems but does not require dosing controls as no chemicals are involved.
