Les guides techniques EHEDG en Anglais

The choice of the most suitable water treatment depends on the water source and intended applications. Referencing CODEX, WHO and EU Directive 98/83/EC, the Process Water subgroup discusses in this document various techniques in relation to main hazards, 3 sources of which are namely: mechanical design and building; normal operation (including stops); and external factors.

Ion exchange, membrane filtration, chlorination/ozonation, and ultra-violet radiation are among the treatments discussed. Other titles from this subgroup are: The prevention and control of Legionella spp (incl Legionnaires' Disease) in Food Factories (2002) and "Safe Storage and Distribution of Water in Food Factories (2004).
