Water Treatment

Background

The methods to be used in purifying raw water into drinking water and, by extension, the cost of purification are determined by the state of the raw water, the occurring pollutants / impurities and their variability as well as the quality of the finished water and the demand situation. It should also be taken into account that the required drinking water quality must be guaranteed even during the aforementioned fluctuating raw water state as well as, if necessary, while the treatment plants are at maximum capacity.

Objective

Therefore, in order to treat the pumped karst water, a feasibility study shall be carried out to design combinations of innovative membrane methods and classical mechanical treatment methods for particle removal and test them at a small scale under local conditions.

Taking the test results into account, a process concept for a central treatment plant, which is expected to be implemented on a large scale by the Vietnamese partners at the Ma U distribution tank, with a volumetric flow rate of 1,000 m³/d shall also be drawn up to supply drinking water to the Dong Van region. Thus, the amount of water pumped through the Seo Ho Pilot Plant can be fully treated and passed on to the connected distribution zones at high quality.

Furthermore, there are plans to prepare the small-scale water treatment plant for permanent operation in the metropolitan area of Dong Van City at the end of the project. As a point-of-use plant, about 10 to 20 m³ of drinking water shall thus be provided for a suitable public building (e.g. school, town hall or hospital).
