System disinfects cultivation water
October 1st 2007 Hanovia UV technology has been
selected by NZ Hothouse, a New
Zealand provider of fresh produce,
to disinfect the water used for soilless
plant cultivation in its
glasshouses.Two Hanovia PMD200
medium pressure systems have
been installed treating up to 68m3
water per hour. UV treatment is
suitable for this application as it is a
clean technology that introduces
no chemicals or unwanted
disinfection by-products into the
water and does not alter its pH.
The UV systems feature an
automatic wiper which prevents
the build-up of deposits on the
quartz tube, ensuring optimum UV
dose at all times.
Photon control panels provide
the operators with data on flow
rate, UV dose and intensity and can
log up to one year's performance
data, which is downloadable to a
PC via an RS323 port. More articles from Hanovia Limited: |
