P roquip's I-GON treatment, an acid-based crystalline agent, has long been tried and trusted by the borehole industry for removing the iron and manganese oxides that lead to bacterial infestation and bio-fouling. Following months of development and trials, Proquip Direct has introduced a reformulated range I-GON 2 and I-GON 3 offering even quicker, more powerful yet still cost- effective cleaning. The new formula uses the proven and safe organic chemicals of the original, making it suitable for the treatment of potable water wells. But intensive work by an accredited water chemistry laboratory has led to exciting improvements in the physical characteristics to maximise cleaning reactions through the process. New I-GON uses grades of chemical that differ to competing systems and in a unique formulation that sustains cleaning action throughout the borehole. Chemical reactions take effect within minutes, releasing controlled cleaning that lasts longer and penetrates deeper to remove iron-related bacteria as well as rust, scale and stubborn deposits. In some cases, a significant improvement in the flow from the borehole has been seen within ten to 15 minutes. The product is totally biodegradable and safe for disposal once neutralised, and does not react with or damage any metallic or man-made material. For user convenience, two crystalline preparations are available tailored around distinct cleaning needs: • I-GON 2 is a fast-acting two- part crystalline powder for the 'bench' cleaning of valves and other pump components contaminated with iron / manganese oxide deposits • I-GON 3 combines three types of modified crystal that control the solubility of the product as it works down the borehole – resulting in an enhanced and consistent clean throughout. It is intended for the in-situ cleaning of the complete borehole (with system offline) or of removed assembly parts before re-installation. In both forms, I-GON falls outside the scope of DWI Regulation 31 (October 1, 2015 revision) and is safe for drinking well applications when used strictly in accordance with A solution: Deep-clean for boreholes instructions. It is constituted, blended and packed in England to ISO 9001 QM systems, offering assured, reproducible product quality as well as improved availability to the UK borehole market. Impact in the field The new formula is already making a positive impact in the field. At the Royal Blackheath Golf Club, it saved the cost and effort of replacing a clogged pump and rising main in a troublesome irrigation borehole. Kent-based first-time user HWS was delighted with the results as director HWS director Darren Hogben explains: "We have been dealing with the Royal Blackheath Golf Club for some time and they were experiencing problems with their borehole as the flow was slowly decreasing. The borehole, installed in 1996, is lined with a 6" steel casing and was drilled 140m into the chalk with a standing water level of 44m. The water is stored in a tank adjacent to the borehole before irrigating the course. "On inspection, we found that the pump and rising main were clogged with iron ochre. Rather than choosing to replace the pump and rising main, we decided to try cleaning the system. We used I-GON3 and within minutes the water started to change to a green colour indicating that the chemical was reacting with the iron. The water was circulated for an hour and then le¥ to stand overnight. The next day the borehole was pumped out and showed an amazing improvement in flow. The flow before we started was 0.5m3/h and a¥er the clean it had increased to 3.3m3/h." Another customer who used I-GON for borehole remediation says: "A¥er two hours, the pump was circulating water at easily double the flow compared to when we started. A¥er 24 hours, the flow had increased back to levels similar to when the pump was brand new." Sound maintenance routines are strongly recommended to allow for timely detection of bacterial activity before bio-fouling takes hold. Routine checks, using proprietary products like Proquip's BART Test Kit, will signal the presence of problematic bacteria in the water source before it has time to grow and spread.
