Ultrafiltration Plant Operation in Petrinja Croatia

This document is a technical report detailing the operation of the Stara Strojarna Ultrafiltration plant located in Petrinja, Croatia, which commenced operations in April 2015. The plant has a production capacity of 7,776 m3/day of filtrate water, sourced from five different wells, and serves a community of 25,000 people. The report describes the plant's configuration, which includes three operational lines, each equipped with 20 DuPont™ UF SFD-2880 modules. The feed water experiences turbidity levels between 8 to 120 NTU, necessitating a pre-treatment process. The cleaning strategy involves continuous dosing of Sodium Hypochlorite (NaOCl) and periodic backwashing to maintain operational efficiency. The report highlights the consistent product water quality, with turbidity values below 0.1 NTU and no bacteriological contamination. It emphasizes the effectiveness of DuPont™ Ultrafiltration membranes in producing potable water without altering salinity. The document concludes with a disclaimer regarding the information provided.
