Water treatment topics are covered in this section. These include different treatment methods, disinfectants and radiation protection legislation. Another topic is energy efficiency in water supply.
W 213-1 Technical Rule - Standard 07/2023
75,24 €*
This Standard W 213-1 covers the principles of particle removal in the treatment of drinking water for public supply. It focuses on the removal of particles in the treatment of waters that may be susceptible to interference from surface waters, in particular river, lake, dam, spring, karst and fissure waters or water ob-tained from riverbank filtration.
DVGW Series of Standards W 213 Part 3 through Part 5 describe water treatment methods that have been specifically designed for particle removal. DVGW Standard W 213-2 and DVGW Standard W 213-6, respectively, cover the assessment and application of granular filter media and the monitoring of water treatment methods for particle removal.
This series of standards does not cover artificial groundwater recharge, which is described in DVGW Standard W 126 “Design, Construction and Operation of Plants for Artificial Groundwater Recharge for Drinking Water Abstraction”.
Likewise, this Standard at hand does not cover processes aimed at e. g. adjusting the pH value of water or removing iron, manganese, organic substances or heavy metals. Such processes also employ the use of filters and can, in certain circumstances, run simultaneously with the particle removal process. These processes are covered in the DVGW Standard series W 223 (Removal of Iron and Manganese) and in DVGW Standards W 214-2 (pH Adjustment), W 239 (Organic Matter Removal) and W 249 (Re-moval of Heavy Metals).
W 1003 Technical Rule- Standard 06/2022 -PDF-Datei-
79,28 €*
This Standard W 1003 relates to the piped supply of public
water under normal operating conditions. Covering the different technical
aspects and value-added steps, it provides an integral overview of how to
describe, analyse and assess the resilience and security of supply in water
supply areas.
W 122 Technical Rule - Standard 08/2013 -PDF file-
79,28 €*
This Code of Practice W 122 comprises all closing‑off structures for groundwater developments by vertical and horizontal filter wells. The new version incorporates operational issues insofar as they have an immediate effect on the requirements placed on the planning and construction of closing‑off structures.
