(author)Aims Most swimming pools use residual disinfectants like chlorine for disinfection. The use of chlorine has several drawbacks: some waterborne-pathogens are chlorine resistant and disinfection by-products (DBPs) may be formed which are associated with various health risks. Therefore, an alternative treatment was developed which consists of...abstract 2017

Keuten, M.G.A. (author), Peters, M.C.F.M. (author), van Dijk, J.C. (author), van Loosdrecht, Mark C.M. (author), Rietveld, L.C. (author)Swimming pools are traditionally disinfected with a residual disinfectant such as sodium hypochlorite. Nowadays, swimming water without a residual disinfectant is increasingly popular, as can be seen by the growing number of (natural) swimming ponds (Weilandt 2015), but health risks for bathers do raise concerns for these type of pools, so some...abstract 2017

Lu, J. (author)The objective of this research was to decrease membrane fouling of a ceramic microfiltration system and at the same time increase the recovery. A conventional operation in micro- and ultrafiltration is an in-line coagulation and a frequent hydraulic backwash. The idea about these frequent backwashes is to limit the accumulation of fouling on the...conference paper 2013

In the Netherlands, the chlorine concentration in swimming pools has to be between 0.5-1.5 mg/L free available chlorine, which is based on a 4-log removal of Pseudomonas aeruginosa within 30 seconds. Besides disinfection of microorganisms side reactions form disinfection by...conference paper 2013
