An Attempt of the Treatment of Underground Water in an Integrated Multifunctional Plant

摘要

AbstractBy means of an integrated multifunctional experimental pilot plant there were tested several process variants for the treatment of carbonic‐acid‐aggressive and manganese‐enriched model water. Deacidification and oxidation of iron‐ and manganese‐constituents are effected by gas exchange with atmospheric oxygen. The hydrated‐oxide particles formed are held back by two layers of foamed polyurethane and a sand bed lying uppermost. The process of neutralization and oxidation as well as flocculation is accelerated by the use of chalk, lime or soda. The effectiveness of the process technology investigated is illustrated by a table of results of small‐scale experiments with model waters prepared from d
