Independent tests show TOC, THMs and combined chlorine all lower following UV treatment


Pina LED Underwater Lighting Fixtures PINA, the famous brand from Istanbul introduces a new lighting technology: LED. In 2008, the latest trends of lighting for swimming pools and all other underwater applications are complemented by the latest PINA lighting equipment range. In addition to the high quality of Pina lights, LED technology is applied so that it gives 5 different colors and multiple color alternatives, including animations and a remote controller for easy use. Each item has 180 LEDs with the highest lumen output. Furthermore, the PINA LED technology uses the same form of PAR56 which gives the ability to change already installed lighting equipment, which have traditional 300w bulbs, with the same ease of changing a regular light bulb!

Recent independent tests carried out at a UK leisure center showed a dramatic reduction in TOC (total organic carbon), THMs (trihalomethanes), and combined chlorine in pool water following the installation of a Hanovia medium pressure UV system. The tests were carried out by WRK Design and Services Limited, an independent chemical engineering consultancy specializing in contract research and development and pilot plant studies. They were conducted at the Lightwaves Leisure Centre in Wakefield.

PINA equipment provide the latest pool lighting technology with the lowest energy consumption rate. Today, there are 5 different models for concrete or liner pools and jacuzzi or fountain lighting in different colors with animations if requested.

The main objectives of the trial were to analyze swimming pool water samples for TOC, THMs, active/free chlorine and TDS (total dissolved solids) before and after the installation of a UV water treatment system. In all cases, there was a significant reduction of TOCs, THMs, combined chlorine and TDS post-UV. Transmission* values were higher post-UV, indicating a reduction in suspended organic material (with correspondingly lower absorbance) as a result of UV. The lower combined chlorine levels also indicated lower levels of organic material, matching the higher transmission values. Chlorine reacts with organic material to form combined chlorine, so lower organics would result in less combined chlorine, lower absorbance, and therefore higher transmission.


Following the trial WRK concluded that, “The results of the analysis indicate that the medium pressure UV system at Lightwaves Leisure Center was beneficial in reducing the TOCs and THMs to very low levels (~ 25 Âľg/liter) up to 14 days after installing the UV system.â€? The report also confirmed the reduction in combined chlorine was also significant. *The condition of the water being treated will determine how well the UV light passes through it (UV transmittance).
