In Vietnam, there have been some studies on desalination but mostly on low and stable salinity and small-scale system. In fact, the salinity varies quite substantialy within seasons. Thus, the main objective of this study is therefore to evaluate the brackish water treatment capacity of different nanofiltration (NF) processes for domestic and drinking water supply for residential areas in Thu Bon river basin.

The purpose of this research was to investigate the technological feasibility of biological filtration process for Mn control in Lorne WTP. This thesis consists of eight chapters. Project background and research objectives are described in Chapter 1. Chapter 2 presents an extensive literature review covering the nature of manganese, manganese analytical methods, manganese control methods, the nature of MOB and biological control of Mn in drinking water treatment. The materials and methods used throughout the experimental investigation for this study are described in Chapter 3.

The rejects and membrane wash water were also treated in the bioreactor, resulted in complete removal of ClO4 ¯ through this approach. This is the first report where biotreatment is adopted as a pre- and post-treatment to membrane process for removing ClO4 ¯ , and this will find field application for treating ClO4 ¯ contaminated ground as well as surface water sources.

This study aims to explore the potential of layered double hydroxides (LDHs) materials for the treatment of contaminated waters by organic pollutants, using a combined dual process, namely adsorptionphotocatalysis. A series of LDHs of ZnCr-X where (X ¼ Cl, SO4 and CO3) were synthesized and characterized by several techniques such as DRX, FTIR, BET, TEM, and UV-Visible spectrophotometry.

Objectives of thesis: Study on phenol treatment in water by ozonation process combined with catalysts. An empirical kinetic model and one quadratic regression equations were built based on experimental data for destroying phenol by heterogeneous catalytic ozonation process with response variables (initial pH, ozone concentration, catalyst concentration and reaction time). Application of phenol treatment in coking wastewater.

Vitamin E Deficiency: Treatment Symptomatic vitamin E deficiency should be treated with 800–1200 mg of αtocopherol per day. Patients with abetalipoproteinemia may need as much as 5000–7000 mg/d. Children with symptomatic vitamin E deficiency should be treated with 400 mg/d orally of water-miscible esters; alternatively, 2 mg/kg per d may be administered intramuscularly. Vitamin E in high doses may protect against oxygen-induced retrolental fibroplasia and bronchopulmonary dysplasia, as well as intraventricular hemorrhage of prematurity.
