  • LIT25 level indicating transmitter controls swimming pool level

    The Town of Okotoks, Alberta I never gave it much thought, but what happens to the displaced water when a hundred people jump into a large public swimming pool? It goes into a surge tank - of course. This Greyline LIT25 Level Indicating Transmitter with ultrasonic sensor is installed in the basement of the Okotoks Recreation Centre in Alberta, Canada. The LIT's 4-20mA output is connected to a ...

  • Ultraviolet disinfection systems, the best solution to school swimming pools

    School swimming pools are a valuable asset, and are now present in the majority of high schools and higher education facilities throughout the UK.  Whilst school pools vary in size, shape and usage, many school swimming facilities are facing a common dilemma in their water disinfection strategy.  Existing treatment regimes are often badly designed, under sized or simply outdated, which ...

  • Hong Kong University of Science & Technology Outdoor Swimming Pool

    The Site: The outdoor swimming pooi has three sand filters, two carbon filters and one ozonator. The ozonator broke down regularly, whenever the temperature in the operating room was too high. The Ozonator was used because management wanted to reduce the chiorine dosage from 3ppm to lppm. Back washing frequency of the sand filters was weekly and the carbon in the carbon filters was replaced ...

  • Association Between Swimming Pool Operator Certification and Reduced Pool Chemistry Violations—Nebraska, 2005–2006

    Previous studies have recommended mandatory education for all public pool operators, but substantiating data are limited. This study evaluates associations between pool operator certification and chemistry violations by using 2005–2006 Nebraska routine pool inspection reports. Training and certification for nonmunicipal pool operators are only required in two Nebraska counties. Free chlorine ...

  • Importance of Air & Water Testing in Indoor Pools

    Have you ever wondered why your eyes hurt or why you have a cough after swimming at an indoor pool? We all assume that it’s from too much chlorine in the pool but that is false! If the pool staff doesn’t regularly test and monitor both the air and water indoors, the environment becomes very toxic and unsafe to everyone in the building. Water is an essential ingredient for all life as ...

  • Gas Detection in Recreation Facilities: Can the same detector work for pools and arenas?

    It is not uncommon for the same recreational facility to offer both skating and swimming amenities, two very different environments with different potential gas hazards. Given the fact that there is a possibility of 6 different types of gas to monitor and the large area between the two types of facilities, a single detector will not provide the monitoring requirements for both areas. It is ...

  • Profile of Ozone/Bromine Sanitation Systems for City of Tucson Municipal Pools

    Due to the inherent risks associated with the use of chlorine gas as a sanitizer for the City of Tucson’s twenty-six municipal swimming pool sites, I found myself in search of an alternative water sanitation method. The challenge was clear; find a system that would be safer to manage than gas chlorine, yet yield the same favorable sanitation and water quality results. Since all the sites ...

  • BioSense a Biofilm Monitor and Controller

    Abstract Biofilms (slime) can form on virtually every nonshedding surface, in a nonsterile aqueous environment i.e. anywhere where a water source is present; such as cooling/heating systems, swimming areas and in drinking water purification. These Biofilms can cause a myriad of problems including; harbouring harmful bacteria such as Legionella, inducing corrosion, and reducing ...

  • Biofilm Control for Industrial Waters

    Industrial operations can face a number of serious problems due to bacterial Biofilms growing in process water systems and cooling tower waters. Biofilm-induced corrosion, mechanical blockages and impedance of heat transfer processes result in huge monetary losses each year. In engineered systems, additional risks of biofilm-mediated contamination include negative public health consequences and ...

  • Controlling waste produced by shopping centres at christmas

    Approximately 6000 tonnes of waste will be produced by the UK’s 5 newest shopping centres over the Christmas shopping season – enough to fill 2.4 Olympic sized swimming pools. Research published by WSP Environment & Energy, using average shopping centre waste, predicts that the major new shopping centre openings in the UK will produce in total over 5,978 tonnes of waste over the Christmas period ...

  • Biofilm control strategies in industrial processing waters

    Bacterial biofilms cause a number of serious problems for industrial fluid processing operations. Mechanical blockages, impedance of heat transfer processes and microbially induced corrosion result in billions of dollars of losses each year. In engineered systems, such as cooling water systems, food processing, and other industrial applications possible risk to public health and product spoilage ...

  • Peroxodisulfate measurement using boron-doped-diamond electrodes

    Peroxodisulfates are strong oxidizing species with various ap-plications. Among others two particularly interesting applica-tions of these compounds are, on one hand, their use as the efficient oxidizing reagent for chemical synthesis, and on the other hand their capacity to act as a non-halogenated agent for water disinfection, e.g. in swimming pools [1]. For these ap-plications, as well as for ...

  • Hazardous waste cleans up its act

    Instead of landfill, incineration is being used increasingly in the UK to dispose of waste while recovering energy. The processes for controlling air pollution at these facilities creates a hazardous waste that represents approximately 3.5% of the original waste input by mass. Around 170,000 tonnes of Air Pollution Control (APC) residue, the hazardous by-product of incineration, is created every ...
