Water & Wastewater Treatment

FilDrop is our business partner with significant experience in the field of water treatment. FilDrop is currently organised in two sectors:
Civil sector (treatment of water, aimed at installers, large distributors, State bodies, etc.);
Industrial sector (treatment of primary water, process water and waste water.);

Types of Activities


Fildrop entrusts the following to certified professional engineering studios: examinations of technical-economic feasibility, design and construction of water treatment systems, on a pilot and industrial scale. The company is capable of providing a complete range of services, from construction to supply, from assembly to ignition, with post-sales servicing, for systems of small, medium and large power, throughout Italy.
