... itself and water quality in the distribution system. Performances are very satisfactory, especially for the two main objectives: elimination of organic matters and of pesticides. The consumers are also satisfied with the reduction of the chlorine taste (chlorine rate has been diminished by facto ...

... in water (triazines and urea herbicides). Experiments were carried out on synthetic waters composed from distilled water to which has been added organic (humic acids) or inorganic (CaCl2 or CaSO4) matter and on a real water matrix collected at the outlet of the grain activated carbon. These matrice ...

... inorganic compounds on seed crystals. Barium sulfate precipitation was examined in a laboratory scale (DU) using supersaturated synthetic (no organic matter) and natural RO and NF concentrates. Effective barium removal for at least 100 h was observed in the case of synthetic concentrate. Earl ...

The pretreatment of raw seawater is necessary to minimize the organic fouling of seawater reverse osmosis (SWRO) membranes. To predict the membrane fouling of the pretreated seawater, the modified fouling index (MFI)... from Collioure, France. The concentration of total dissolved solids was 32,760 mg/L. The molecular weight (MW) of the initial seawater organic matter (SWOM) ranged from about 14160 Da to 280 Da. FeCl3 flocculation removed the majority of SWOM, while PAC adsorption could not remove the lowest MW

This study aims to find news a die of purification for a wastewater reuse. Primary effluent contains organic mineral, dissolved and suspended matter (colloids). Microfiltration or ultrafiltration is adequate for producing disinfected clear water suite ...

... chloride (FeCl3) flocculation as a pretreatment to seawater reverse osmosis (SWRO) were investigated. Their ability to remove turbidity, seawater organic matter (SWOM) and controlling the feed water quality of SWRO was evaluated. Flux decline of SWRO and membrane autopsy were studied. Titaniu ...
