PWTAG Technical notes are updates or new material for the standards and guidance given in the PWTG book, Swimming Pool Water and the PWTAG Code of practice and should be read in association with these publications.
Every year apparently new and sometimes interesting water treatment processes hit the swimming pool market – often in response to real or imaginary problems with the standard treatment methods detailed in this book.
PWTAG has endeavoured to assess these processes – not necessarily to give approval – but to protect pool operators against false claims as well as to encourage novel ideas. Sometimes this has involved PWTAG in sponsoring research – and often it involves detailed correspondence, discussions and presentations by those marketing the products. Rarely has PWTAG been able to come to a satisfactory conclusion that pleases all parties.
