Filterdirect UV Water Purifiers

 

The Filterdirect range of UV units have been manufactured in the UK for over 25 years.  These products are market leaders and approved by health specialists for domestic use.

 

How Does Ultraviolet Disinfection Work?

 The disinfection unit comprises of an enclosed chamber with an inner sleeve of high purity quartz, which contains a germicidal (shortwave ultraviolet) lamp.  Water passes through the chamber and is subjected to the UV light which shines through the quartz sleeve.

Shortwave ultraviolet destroys the genetic structure of micro organisms, therefore bacteria or viruses in the water exposed to the UV light will be destroyed.

Ultraviolet light is one of the safest ways to disinfect water since it does not use chemicals and therefore cannot be overdosed.  It also does not alter taste.

PERFORMANCE AND QUALITY

UV disinfection units are rated according to the UV transparency of the water, flowrate and level of bacterial kill.

Our units are rated conservatively to cope with bacterial problems on well water supplies, providing they generally meet EU water requirements.

15 and 30 watt domestic systems include a flow restrictor to ensure that the unit capacity cannot be exceeded.  These units are also rated for reduced efficiency at the end of lamp life.

 

 

Do not assume that alternative UV units are equal in reliability or can achieve satisfactory disinfection levels throughout lamp life.  “It is always possible to build something cheaper by cutting corners”.  The generally accepted minimum dose level for UV disinfection of potable water is found in ANSI/NSF standards number 55.  These state that a minimum dose level of 38mJ/cm² is required to ensure adequate treatment of drinking water.

UPVC / STAINLESS STEEL

Both UPVC and stainless steel chambers are available, each with over twenty years of proven reliability.  UPVC units offer the advantages of UV disinfection at competitive prices to the domestic user, whilst an extensive range of 304 Grade stainless steel chambers are designed to meet the stringent requirements of the food industry. 
 

Available options

UV Monitor, Lamp/Electric Failure Indicator and Hours Run Meter.
 

PRE FILTRATION

It is strongly recommended that a five micron particulate filter be fitted before the unit to prevent sediment from obstructing the UV light.
