Concentration factor

The possibility of olive mill wastewaters (OMW) treatment and concentration by membrane distillation has been investigated. The objective is to obtain pure water and a concentrate containing high amounts of polyphenols, which can be extracted later. Two types of commercial membranes, polytetrafluoro

The results of concentration experiments on model dye solutions containing anionic surfactant and mineral salts were reported. The objective of the study involved recovery of valuable substances and water reuse. The membrane efficiency as well as dye and surfactant rejections during concentration te

A thermodynamic modeling of saline waters is achieved taking into account acid-base, ion associates formation and precipitation equilibrium. A microcomputer program, written in the graphical language LabView accomplished the necessities of iteration for the solution of simultaneous equations, calcul

In several areas like water desalination and geothermal applications, the occurrence of silica in the used waters is undesirable. Many studies show the complexity and the diversity of the topic. For a better understanding of some of its analytical aspects the determination of amorphous silica conten
