Innovative Flow Analysis Method for High Loading Rate DAF
Dissolved air flotation (DAF) is a well established method for removing suspended solids from wastewater that is gaining ground in the pretreatment of seawater for desalination. The authors describe a method for analyzing the flow of water in DAF to inform better design of DAF tanks. This article first appeared in the August 2014 issue…

Why MFI is edging SDI as a fouling index
PARTICULATE FOULING has plagued reverse osmosis (RO) systems since their first use in desalination and remains a persistent issue today for RO and other pressure-driven systems such as microfiltration (MF), ultrafiltration (UF) and nanofiltration (NF). In the early 1960s, the Du Pont company/Permasep Product successfully launched the hollow-fine-fibre (HFF) permeator onto the desalination market, where…
