  • Nanofiltration for enhanced removal of disinfection by-product (DBP) precursors in swimming pool water–retention and water quality estimation

    Three nanofiltration (NF) membranes with a chlorine tolerance ≥ 1 mg L-1 were applied to reduce DBPs and their precursors in swimming pool water. A lab scale plant with crossflow modules was installed in by-pass at the sand filter outlet of a swimming pool for a period of several weeks. The chlorine tolerances of the membranes SB90 and NP030 were found to be adequate for filtration under swimming ...

  • Ozone is Not Just for Residential Potable Water Treatment

    It has been over 170 years since the d iscovery of the ozone (O3) molecule. Since that time, scientists and engineers have been testing and evaluating ways to use ozone in many different processes, from water and air treatment to surface and food sanitation. The evolution was somewhat slow in the early days, taking nearly 50 years before Europeans found, in 1886, that ozone could be used for ...

  • Sanitation Using Ozone & Chlorine

    For nearly 100 years, ozone has been used all over the world for water sanitation. It is nature’s strongest oxidizer and has a byproduct of pure oxygen. Chlorine, on the other hand, is a very effective, time-proven chemical, but is ineffective against hard-to-kill microorganisms such as cryptosporidium. It also has some unpleasant byproducts. Together, however, these two substances can ...

  • How to Plan Stormwater Management for Urban Areas

    Water is a vital commodity in our lives, but it is possible to have too much water all at once in our lives, especially following violent storms or snow melt. This excess water, lying on the ground, swelling rivers, canals and drains to over-capacity is known as stormwater. In order to make the best use of this water, local authorities need to safely contain stormwater while any ...
