With a 100% corrosion-resistant and UV inhibited dual reactor design, it incorporates removable inlet/outlet unions, the ability to increase the system lamp wattage in the field, a corrosion-resistant poly-meric exterior, stainless steel inner reactor reflector for increased intensity, pressure gauge, automatic On/Off power, and plug in electrical components. The Trident is available in four capacities from 44 GPM to 168 GPM (10 m3/hr to 38.2 m3/hr).
HANOVIA ACT ON REDUCING UV OPERATING COSTS
Hanovia’s award-winning Photon UV products have been backed up by the next generation SwimLine UV system which comes after extensive research and pools trials and is re-engineered to provide lower capital costs and lower operating costs than previous UV systems.
It offers two fold protection for pool operators: water disinfection and removing combined chlorines and is incorporated into existing water treatment systems or can be included from the start into new builds. It is available in a range of configurations, from axial and in-line to U-shaped, making it perfect for any size of pool and every kind of plant layout.
SwimLine dramatically reduces the amount of chlorine required. There is less backwashing and dilution, less waste and notably purer water. The air around the pool is also much more pleasant. Hi-tech sensors and a microprocessor controlled computer interface give unprecedented control over the system – even from remote locations. Continuous UV monitoring and energy optimisation mean the system is more efficient and economical to run, while built-in alarms warn of low UV, power failures or other changes.
The SwimLine uses Hanovia’s UVlux, broad spectrum UV arc tubes as standard, and automatic wipers keep the quartz sleeves housing

Many leisure operators are still installing UV systems to ensure water does not pose a risk to public health
the UV arc tubes clean, so the only regular maintenance is an annual service at which the UV lamp is changed.
Combined chlorines or chloramines are responsible for the distinctive ‘chlorine’ smell associated with indoor chlorinated pools. They also cause sore eyes and irritated skin and are a major cause of rust within indoor pool complexes. UV not only destroys chloramines, but is also an effective disinfectant in its own right.
TRIOGEN NEW SYSTEM OFFERS LOW COST INSTALLATION AND MAINTENANCE UV and ozone water treatment specialists Triogen strengthened their place in the growing UV market, with their new Uvaray CF system for commercial pools and their low pressure TR2 UV range for residential pools, spas and water features.
The Uvaray Cross flow system, now available, has been developed over 18 months as an addition to their range, providing ease of installation and covers flow rates from 20 to 830 m3/h. The approved system utilises a 316L stainless steel reactor, fitted with a DVGW approved UV sensor, reactor temperature sensor and an automatic ‘smart drive’ wiper system. The reactor also features quick release UV lamp connections making lamp replacement simple. The system offers high efficiency, easy low cost installation and maintenance.
Also new for 2012 is Triogen’s TR2 low pressure UV system, designed for disinfection of small pools, spas, ponds and water features. The four TR2 models covers flow rates up to 40 m3/h and are manufactured in UV inhibited polymeric materials making them suitable for pools utilising both salt water chlorinators or standard chemical dosing. The system offers reduced chemical consumption, improved algae control and water clarity.
AQUA MODUS SALT ELECTROLYSIS OFFERS A LOGICAL SOLUTION Salt electrolysis offers a logical solution for swimming pool water treatment – generating chlorine on-site, in a system that simply recycles the ingredients again and again, using a contemporary version of the 150 year old process of saline electrolysis.
The issue has always been how to measure the pool chemical levels accurately and automatically. Legacy probes simply don’t work accurately in electrolysis systems. The eSystem from AquaModus has overcome the issues and now provides very accurate dosing based on frequent laboratory style analysis of the water chemistry. Salt is automatically topped up too. Some might argue that the usual chlorine problems still exist but consider that the chlorine produced by the carefully designed electrolysis cells is extremely pure, effectively destroying chloramines as they pass through, before being diluted in the pipe work as it enters the pool.
In considering a salt-electrolysis system, make sure it is correctly specified not just for the size of pool but also the maximum bather load expected. Such systems respond well to sudden changes in the number of swimmers, being able to change chlorine generation quickly and effectively, throttling back to conserve power when it is appropriate to do so.
With effective cell design, salt concentrations are reduced to the point where bathers remark on the water quality, and don’t notice the very low salt concentration in the water.
The advantages are simple: One system for the entire disinfection needs of the pool, tightly controlled dose levels, the effective de- chloramination, and low power consumption and
with CO2 control of pH, no hazardous chemicals to handle.
