Deionised Water

UK Leading Pure Water Suppliers.

Deionised Water, Distilled Water, Demineralised Water.

What is the difference?

Deionised Water

Deionised or Deionized water (often referred to as DI water or de-ionised water) pretty much explains the type of water in the name. It is water that has had most of its mineral ions removed, such as cations like sodium, calcium, iron, and copper, with anions such as chloride and sulfate also being removed in the process. 

Demineralised Water

Demineralised or Demineralized water is a term often used in parallel to Deionized water, meaning it is water that essentially had all minerals found in natural water removed. The water is manufactured in a chemical process, using our on site Reverse Osmosis purification system. Read more about the process below.

Distilled Water

Distilled water is produced through the process of distillation. This involves boiling the water into vapour, then condensing it back to liquid into a sterilised storage container. The impurities that do not boil into the vapour will remain in the original container, which yields a exceptionally high purity of water.

Our Purification Process

Using our on site range of unique Reverse Osmosis purification systems, our water is first put through a process of removing organic matter. Once that is complete, it then passes through a mixed bed deionising resin, which removes the cation and anion impurities that are mentioned above. 

The maximum level of impurities now is typically <1 microsiemens (μS). To complete the purification process, the water is finally passed through UV sterilisation, and then through a 0.2 micron filter. 

Better than EP Grade Standard

Our RO System produces pure water to <0.5μS consistently, meaning our highly purified water easily meets the worldwide recognised EP Grade Standard.

What grade do you require?

The Industrial Grade of Deionised Water is the ideal solution for use with antifreeze, coolants, lubricants and battery top ups. Furthermore, the ability for use in forklifts, machine maintenance and other sitewide processes make this grade of water ideal for a variety of applications in this sector.

pH Mg/l = 7.1 | TOC Mg/l = <2 | Chloride Mg/l = <0.1 | Nitrate Mg/l = <0.1 | Conductivity uS/cm = <1.3 | Lead Mg/l = <0.01 | Copper Mg/l = <0.01 | Iron Mg/l = <0.01 | Cadmium Mg/l = <0.01 | Cromium Mg/l = <0.02 | Nickel Mg/l = <0.01 | Zinc Mg/l = <0.02 | TACC @ 37 degrees C Cfu/ml = 0 | TACC @ 22 degrees C Cfu/ml = 0 | Endotoxin EU/ml = 0.02

Our cosmetic grade water passes through a 10-stage filtration system including ultraviolet filtration to ensure no microbiological components are within. The nuclear grade resin also effectively removes ionic components to ensure optimal water purity. Our current cosmetic manufacturers utilise the water to dilute and thin a range of products including face creams, moisturisers, shampoo’s, soaps and more.

pH Mg/l = 7.1 | TOC Mg/l = <2 | Chloride Mg/l = <0.1 | Nitrate Mg/l = <0.1 | Conductivity uS/cm = <1.3 | Lead Mg/l = <0.01 | Copper Mg/l = <0.01 | Iron Mg/l = <0.01 | Cadmium Mg/l = <0.01 | Cromium Mg/l = <0.02 | Nickel Mg/l = <0.01 | Zinc Mg/l = <0.02 | TACC @ 37 degrees C Cfu/ml = 0 | TACC @ 22 degrees C Cfu/ml = 0 | Endotoxin EU/ml = 0.02

Our food and beverage grade water is used as a raw material in food manufacturing, processing, and machine sanitation. The ultraviolet filtration ensures no microbiological components are within, helping distilleries and food factories to preserve their products’ flavour during production.

pH Mg/l = 7.1 | TOC Mg/l = <2 | Chloride Mg/l = <0.1 | Nitrate Mg/l = <0.1 | Conductivity uS/cm = <1 | Lead Mg/l = <0.01 | Copper Mg/l = <0.01 | Iron Mg/l = <0.01 | Cadmium Mg/l = <0.01 | Cromium Mg/l = <0.02 | Nickel Mg/l = <0.01 | Zinc Mg/l = <0.02 | TACC @ 37 degrees C Cfu/ml = 0 | TACC @ 22 degrees C Cfu/ml = 0 | Endotoxin EU/ml = 0.02

This particular grade of water is often diluted into a variety of Hygiene products such as detergents, sanitisers, disinfectants and fogging solutions. No microbiological components are left within due to our 10-stage filtration system that includes ultraviolet filtration.

pH Mg/l = 7.1 | TOC Mg/l = <2 | Chloride Mg/l = <0.1 | Nitrate Mg/l = <0.1 | Conductivity uS/cm = <1.3 | Lead Mg/l = <0.01 | Copper Mg/l = <0.01 | Iron Mg/l = <0.01 | Cadmium Mg/l = <0.01 | Cromium Mg/l = <0.02 | Nickel Mg/l = <0.01 | Zinc Mg/l = <0.02 | TACC @ 37 degrees C Cfu/ml = 0 | TACC @ 22 degrees C Cfu/ml = 0 | Endotoxin EU/ml = 0.02

To ensure the ultra-pure quality of deionised water, this grade passes through our 10-stage filtration system using ultraviolet filtration and nuclear grade resin to effectively eliminate all microbiological and ionic components. This makes our Pharma/Lab Grade water ideal for our customers applications in instrument cleaning, calibration, autoclaves, and a plethora of pharmaceutical and medical purposes.

pH Mg/l = 7.1 | TOC Mg/l = <2 | Chloride Mg/l = <0.1 | Nitrate Mg/l = <0.1 | Conductivity uS/cm = <0.1 | Lead Mg/l = <0.01 | Copper Mg/l = <0.01 | Iron Mg/l = <0.01 | Cadmium Mg/l = <0.01 | Cromium Mg/l = <0.02 | Nickel Mg/l = <0.01 | Zinc Mg/l = <0.02 | TACC @ 37 degrees C Cfu/ml = 0 | TACC @ 22 degrees C Cfu/ml = 0 | Endotoxin EU/ml = 0.02
