WATER TREATMENT SYSTEMS
“POOL CHEMICAL DISINFECTION IS VERY MUCH PART OF A SYNERGISTIC SYSTEM THAT INCLUDES CIRCULATION, FLOCCULATION, FILTRATION AND PH CONTROL AND MUCH MORE.”
down thus protecting the pool from germs; the formation of mould, bacteria and algae is kept under control and the use of chlorine and other chemicals can be reduced by up to 80%. In addition, UV-C prevents the smell of chlorine and irritation to the skin and eyes and they are more environmentally-friendly than traditional methods.
PROPURE SYSTEMS FEATURE A COMBINED PROCESS The ProPure:SV range uses the latest technology to create crystal clear pool water. All systems incorporate a scientific process called hydrolysis combined with either industry standardionisation or UV treatment and complemented by automated pH and ORP control.
Monitored by the ORP demand, hydrolysis is achieved by a controlled electrical charge being passed through a combination of specially coated titanium plates, which separates the water into its constituent hydrogen and oxygen molecules. This reaction then reforms quickly and briefly into associated chemicals such as hydrogen peroxide, atomic oxygen and ozone. All three of these carry a significantly higher relative value (ORP) than chlorine gas or indeed sodium hypochlorite and, by the time they reach the pool, have reformed into H2
O
leaving no harmful traces in the pool water. The ProPure:SV Ion system utilises an automated copper/silver ionisation process directly treating the pool filter with copper and silver ions that on their own merits are a very efficient biocide and have been used for many years.
The new SV UV Scenic has the same intelligent control unit as the SV Ion but incorporates ultraviolet treatment, thus

Triogen’s UVARAY CROSSFLOW medium pressure UV system, designed for commercial pools and spas
eliminating the requirement for copper/silver. The SV UV Scenic ultraviolet radiation which uses a wavelength of 253.7nm, across a process of photolysis and photo-oxidation, destroys the organic matter in pools. UV sterilisation has been used for many years in the pool industry but until now has always required chlorine donors alongside.
All systems are automated and once set up, require six or 12 months servicing. This can be completed by one of ProPure’s service engineers or after training, any competent technician.
For 2013, ProPure are also launching a new remote monitoring system for sites that want additional support and backup.
EASE OF INSTALLATION AND LONG TERM RELIABILITY FROM TRIOGEN UV and ozone water treatment specialist Triogen have a wide range of products for the treatment of pool water. Their new UVARAY CROSSFLOW and
UVALITE CROSSFLOW medium pressure UV systems are designed for commercial pools and spas. The systems have been developed over 18 months as a further addition to the company’s UV range and provide optimal ease of installation and long term reliability. Covering flow rates from 40 to 830 m3
/h
the CE approved systems utilise a 316L stainless steel reactor, UV monitor, reactor temperature sensor and an automatic ‘smart drive’ wiper system. The reactor also features quick release UV lamp connections making lamp replacement quick and easy. The new

systems offer high efficiency, plus low cost installation, operation and maintenance. Triogen’s TR2 range is designed to provide reliable, cost-effective treatment and improved water quality for domestic pools and water features. The range offers models with one, two, three or four low-pressure UV lamps, treating flow rates of up to 40 m3/h with a UV dose of 30 mJ/cm2
at the end
of the 18 month lamp life. The lamps are powered by electronic ballasts housed within the reactor top cap and feature a pressure shutdown switch for system protection, while a centre ring visually indicates the lamps are operational when powered up.
The suffix to the model designation (e.g. TR2-4) indicates the number of UV lamps provided. The new models are designed to have a small footprint and low power consumption. The TR2 systems with, corrosion resistant vessel, are easy to install, with selectable inlet and outlet positions. The 2-inch and 63mm PVC inlet and outlet unions provided on all four models are designed to allow easy connection to existing or new PVC systems.
HANOVIA’S SWIMLINE SYSTEM AIMS TO REDUCE UV OPERATING COSTS
Hanovia pioneered the use of UV in swimming pools in the 1980s and since then has installed thousands of systems around the world. The company’s award-winning
