general. Up until the year 2000, the European standard for drinking water was 50 µg · L –1 of As, a target that was within the reach of clarification or carbonate removal treatment in most cases. Since this standard was modified (1998 European directive 98/83/CE), the limit has been lowered to 10 µg · L –1 of As, and this has led to the development of more specific processes
Biological iron and manganese removal - Degremont®
These treatments apply specifically to ground water that is lacking in oxygen and that contains reduced and dissolved iron and manganese (Fe 2+ and Mn 2+ ions).Removal of these two elements has, for a long time, been based on physical-chemical oxidation using the oxygen contained in the air for iron and a powerful oxidant for manganese; thus, the basic system included extensive water aeration
Clarification Filtration Ferazur Drinking water Iron removal Carbonate removal Oxidation Iron removal... manganese removal. fundamental concepts of water treatment processes and technologies as well as degremont® solutions applied to treatment line and adapted to each use of water. Designed by field men for field men, this valuable
drinking Water treatment: salinity removal - Degremont®
Remember that excessive salinity (seawater or brackish water) can only be reduced by using the reverse osmosis or electro dialysis membrane techniques (see chapter separation by membranes) or by distillation (see chapter degasification, odour control, evaporation).. If the aim is to use membranes to resolve a divalent ion problem (or ions having a higher valency), then nanofiltration should be
38 Iron and Manganese Removal Handbook SEQUESTRATION Sequestration is a form of treatment in which a chemical, known as a sequestrant, is added to groundwater. The chemical forms a bond with iron and manganese ions, allowing them to remain in solution. Seques-tration for drinking water treatment of iron and manganese is generally

Water treatment handbook - 1991 sixth edition Degremont. ISBN: 2950398413. A useful handbook on water treatment for engineers and students. Volume 1 1. Water, a fundamental element. 2. Treatment, what type of water and why? 3. Basic phsyysical-chemical processes in water treatment. 4. Basic biological processes in water treatment. 5. Methods
Water Treatment for Iron and Manganese Removal. Water Treatment for Iron and Manganese Removal Polyphosphate Treatment Polyphosphates react with dissolved iron and manganese by trapping them in a complex molecule that is soluble in water (Figure 2). As a result the iron and manganese are not available to react with oxygen and precipitate.

Specifics Water treatment manganese removal - Degremont® Bacteria involved in biological manganese removal grow far more slowly than iron oxidising bacteria Therefore, the plant takes far longer to start up and may require 1 to 3 months of natural seeding (in fact, that is why the feasibility of this type of process was noticed ,
Water treatment plants have physical quality criteria including screening and controlling colour, odour and temperature. Also, they have a series of chemical quality criteria including chemical quality refinement, hardness removal, desalination, fluorine injection and alkalinity which some of them are investigated in this study (Spellman 2013; Ang et al. 2015; Hua et al. 2015).

Color removal from waters with low turbidity requires considering specific unit in water treatment plant (Nalco, 1988). Color removal by chemical oxidation, especially when chlorine is used as oxidative agent, produces problematic products (AWWA, 1999; Kawamura, 2000; Rezaee et al., 2008).
