ReAgent Installs Cutting Edge Water Purification System

Share Article

ReAgent Chemicals, a leading UK chemical supplier, has installed a state of the art deionized water purification plant worth well over £50,000 in a new manufacturing facility in Cheshire.

Deionized Water

ReAgent supplies a wide range of chemicals and deionized water is a key component across many product lines

The water produced is pharmaceutical standard

The specialist equipment was installed by experts in a newly-purchased warehouse (the third owned by ReAgent) over a period of about one month. The main piece of machinery, a Veolia Strata Plus deionization plant, didn’t take very long to install but the company also fitted an array of after-market modifications plus a new ring main which pipes the water around the entire manufacturing plant.

ReAgent manufactures deionized water which is used in many of the chemicals they supply. The new system can produce exceptionally high quality water with a conductivity of less than 0.05 microsiemens per cm at its source. And it can do this at a rate of more than 10,000 litres per hour. ReAgent says the plant can theoretically produce more than this – probably close to double the amount – but the pressure of the mains water supply limits the flow so they don’t actually know what the plant is truly capable of.

However, although purifying 10,000 litres of water in an hour is impressive, it's not the size of the plant which makes it interesting. What makes it unique is the way ReAgent has set up the machine with a lot of additional pieces of equipment.

Mains water enters the building where it initially gets treated with a Softener to remove Calcium Carbonate. The softened water is then pre-filtered twice before it enters the deionization plant, firstly at 5 microns, then again at 1 micron. After this the water is then deionized (where all the Anions and Cations are removed such as calcium, magnesium, chloride and fluoride) then it gets sent through a UV filter to remove any bacteria. The recently deionized water is then filtered again, through a 0.2 micron filter to remove any dead bacteria, and finally stored in a holding tank where it is continually circulated back through the UV treatment and 0.2 micron filter so the treated water is kept moving until it is required. The water is also tested routinely for Total Viable Count (of bacteria) which is measured in Colony Forming Units per ml, the results of which are normally zero. The water produced is of a pharmaceutical standard.

Water is a key ingredient in many of the chemical solutions manufactured by ReAgent, which highlights the importance of this new piece of machinery. “For ReAgent, the quality of our products is of upmost importance” says Richard Hudson, Managing Director. “We supply a wide range of chemical solutions and deionized water is a key component across many of our product lines – such as buffer solutions, standard solutions, conductivity standards and many other chemical products”.

“We have a routine maintenance programme where the quality of water is checked daily, as well as being recorded for every batch we manufacture. We also monitor the pressure before and after all filters, as fluctuations indicate blockages (and thus new filters), along with salt levels in the softener and the chemical level which are used in the resins. Basically we check as much as we can as often as we can because the quality of the water produced goes hand in hand with the quality of our products.”
