Ecology Galvanization ZGR Kovačić has a completely resolved system of technological wastewater treatment, which begins with the selection of chemicals used in metalworking processes. In our processes, we use only environmentally friendly and acceptable chemicals from renowned manufacturers that contain no cyanides or hexavalent chromium. We are Cr VI – free electroplating job shop. The wastewater treatment process is fully automated. It consists of neutralization of acid – alkaline rinsing waters, and precipitation of metal hydroxides in the form of sludge, which is filtered through filter press, where a cake containing 70-75% of water is obtained. The treated water, which fully meets the parameters set by the law, goes to the public waste water collecting system. Regular analyzes of water by an authorized institution meet the requirements set by the law. In order to reduce the volume and mass of sludge, we were the first in the Republic of Croatia to start drying galvanic sludge in 2004. A low-temperature WATROMAT® dryer from Swiss manufacturer WATROPUR AG was purchased for this purpose. Ventilation air undergoes a scrubber wash process and leaves the process completely clean. ZGR Kovačić has a certified environmental management system ISO 14001: 2015.

Ekologija Galvanizacija ZGR Kovačić ima u potpunosti riješen sustav obrade tehnoloških otpadnih voda koji započinje već kod izbora kemikalija koje se koriste u procesima obrade metala. U našim procesima koristimo samo ekološki prihvatljive kemikalije renomiranih svijetskih proizvođača koje ne sadrže cijanide i kromate. Proces obrade otpadnih voda je u potpunosti automatiziran. Sastoji se od neutralizacije kiselo – alkalnih voda i taloženja hidroksida metala u obliku mulja koji se filtrira kroz filter – prešu, gdje se dobiva filter kolač koji sadrži 70 – 75% vode. Obrađena voda koja u potpunosti zadovoljava parametre određene zakonom o vodama odlazi u sustav javne odvodnje. Redovite analize vode od strane ovlaštene ustanove ispunjavaju zahtjeve iz vodopravne dozvole. U cilju smanjenja volumena i mase mulja prvi smo u Republici Hrvatskoj započeli sa sušenjem galvanskog mulja 2004. godine. Za tu namjenu nabavljena je niskotemperaturna sušara WATROMAT® švicarskog proizvođača WATROPUR AG. Zrak iz ventilacija prolazi postupak pranja u skruberu i napušta pogon potpuno čist. ZGR Kovačić ima certificiran sustav upravljanja zaštitom okoliša ISO 14001:2015.
