Filtration is a key control point, when optimised and monitored thoroughly, increases the chance of producing safe drinking water. An additional advantage of implementing good operational practices will be a considerable saving in media replacement costs and filter rebuilds, when deterioration of the filter is noted but it is all too late.
The Practical Guide to the Operation and Optimisation of Media Filters has an introduction into the importance of filtration in improving public health outcomes. There is a chapter on hazards, risks and control measures for managing drinking water from catchment to tap.
Filter optimisation, backwashing, monitoring filter function and filter media are covered in dedicated chapters. Further to this there are detailed chapters on repairing and rebuilding media filters.
