Horizontal Vaccum Belt Filters for Kazphosphate
Following the successful commissioning and performance of three 85 m² DELKOR Horizontal Belt Filters (HBFs), Kazphosphate placed an order for three additional 110 m² HBFs as part of their expansion project. These units were commissioned in 2022, strengthening DELKOR’s position further in the field of large-scale phosphoric acid filtration.
DELKOR is currently executing the largest phosphoric acid filter in its portfolio, with a filter area of 145 m² — a significant milestone in high-precision filtration technology. Previously, DELKOR supplied 133 m² and 121 m² HBFs, which were precursor installations to the current flagship project.
