LOW & NO CHLORINE
“FOR DOMESTIC POOLS AND SPAS THE DRIVE TOWARDS SALT CHLORINATION IS GROWING WORLDWIDE AND THE BENEFITS OF ITS USE INCLUDE NO MORE EXPENSIVE PACKAGED CHLORINE, SHOCK TREATMENTS OR ALGAECIDES AND NO MORE EXPOSURE TO CHLORINE POWDERS, DANGEROUS STORAGE, ETC”
The Bright Blue salt chlorinator from Thermalec generates chlorine from within its own electrolysis cell and allows the enjoyment of a softer and silkier feel to the pool
where a process of ion separation takes places, breaking the salt into a hypochlorous acid (chlorine). The chlorine is released electrochemically, under control. Afterwards the ions recombine, recomposing the salt. The process repeats itself continuously or whenever necessary.
SEAL Pool Equipment is another company specialising in the design and manufacturing of top of the range chlorinators and other swimming pool equipment.
The company first launched its popular range of saltwater chlorinators, the CL series for residential facilities. They have also recently developed the SEAL Pup, a chlorinator for small pools and spas. Reverse polarity, low salt and water flow alarms, manual and automatic settings and electrode monitoring are some of the common features to all their chlorinators.
The process requires the pool or spa to have a salt concentration of between 3 and 6 g/l. This is still classified as fresh water (by comparison, sea water contains 20 g/l of salt on average).
UV WATER TREATMENT MADE EASY IN RESIDENTIAL POOLS AND SPAS With the latest advances in UV disinfection technology, keeping water safe from unhealthy or undesirable organisms need no longer be just a case of waging chemical warfare. For residential swimming pool and spa owners, the UV options now available from leading water treatment specialist Triogen – via Golden Coast – include cost- effective TR2 units which save on both capital and running costs while improving water quality.
The TR2 low-pressure UV system is used in conjunction with chemical treatments, substantially reducing the amount of chlorine

or other sanitiser needed. This means lower levels of chemicals in the water and lower chemical bills. Irradiation by its high-output UV lamps is highly effective in controlling algae and killing chlorine-resistant organisms. What’s more, it releases no by-products into the water. Electricity consumption is minimised by the high efficiency of the low-pressure lamps and is enhanced by an automatic pre-set internal flow switch which shuts the unit down when there is no flow. The units are compact and are designed for easy, inexpensive installation and connection. Maintenance costs are reduced by a robust construction that includes a 100% corrosion-resistant, UV-inhibited, polymeric reactor vessel and long (18 months) UV lamp life. There are four models in the TR2 range,

giving a choice of two, three or four UV lamps, according to the flow to be treated – which can be anything up to 40 cubic metres per hour. A powerful UV dose of 30 mJ per square centimetre can be delivered. Triogen water treatment systems are distributed in the UK by Golden Coast, whose Managing Director Jamie Adams says: “Triogen’s developments have given pool and spa owners many new options and have brought increased levels of confidence in the health of wet leisure environments. The Triogen range, which includes a wide variety of systems for different circumstances, can offer a cost-effective solution for every owner.”
ATG OPTIONS TAILORED TO SPECIFIC REQUIREMENTS
atg UV’s range of treatment systems are proven to improve the swimming pool environment by improving water quality, air quality and safety, leading to increased customer satisfaction. UV systems not only provide disinfection against the 17 known chlorine resistant micro-organisms, such as Cryptosporidium and Giardia, which have a thick outer membrane making them highly resistant to traditional chlorine disinfection, UV also destroys chloramines. Chloramines are formed when free chlorine reacts with organics, such as sweat, body fats and urine, brought into the pool environment by bathers. atg UV Technology now offer a number of UV systems with pre selected options tailored to the specific requirements of swimming pool operators. Typical swimming pool UV units should include: 316L stainless steel chambers, UV monitoring, automatic wiper systems, strainer baskets and the option for half to full power for energy savings during periods of no/low use.
Additionally, UV manufacturers should always follow best practise when sizing a UV system, ensuring to supply UV equipment capable of providing a 60 Mj/ cm2 dose (average) at a transmission of 94% and taking pool usage into account e.g. typical bather load, additional disinfection technologies, such as filtration and pool volume turnover.
HANOVIA’S ‘SWIMLINE SPLASH’ DESIGNED SPECIFICALLY FOR SMALL FLOWS
Owners and operators of small pools and spas don’t need large UV systems to treat their water. What they do need, however, is
