END USER Public utility provider, Gyulai Közüzemi Nonprofit Kft.
CUSTOMER Pure-Aqua Kft.


The client was not satisfied with the existing belt-filter press because of high repair and maintenance costs, therefore they decided to change it during the general reconstruction of WWTP. The client was looking for sludge dewatering solution with low power consumption as well as small footprint to be installed in place of the existing filter press.


After the detailed analysis and comparison with other manufacturers, the client chose our dehydrator MDQ-201. During the design stage, Esmil specialists actively assisted in the development of sludge dewatering scheme.
