摘要

This article is a case study about a real environmental project in Hungary that is financed by the Hungarian Government.nThe main task of the project is to re-cultivate the area of an old leather factory in the town ofnSimontornya, including soil exchange and underground water rehabilitation. This article itself mainly givesndetailed technological information about the underground water treatment process, but also basic informationnabout the recultivation parts of the whole project. The basic question of the underground water treatment projectnwas how to withdraw 168,000 m3 of highly polluted underground water, remove the very heavily polluted metalsnand salts (arsenic, boron, chrome, ammonia, nitrate, chloride) and infiltrate the treated water back into thenground, all over a period of 2 years. The solution implemented is an integrated membrane system (NF; RO) includingnconventional physical and chemical pre-treatment and softening, with a selective ion exchange process fornpost-treatment. One further key aspect of the technology applied was to minimise the waste created during thenwhole process.
