The aim of this project was to improve process water quality for the leader of the world cement sector-Tasluja Cement tfactory of Lafarge Group.
Prismatic water tank with 844 m3 volume is installed to store raw water. Raw water is fed to automatic multi-layer sand filters by system feed pumps made from 304 stainless steel with 67 m3/hour capacity each. tfeeding system includes service and standby pumps.

Disinfection is realized online. Sand filter has automatic, time-controlled backwash system. All controls of filtration system are realized by PLC and solenoid panels. After removal of physical contaminants from raw water, water is passed through reverse osmosis for removal of ions by the membrane technology. Reverse osmosis system is designed according to the raw water quality and can produce 50 m3 of treated water per hour with the 75% efficiency. The performance of the whole process is controlled by water parameters measurement at certain points of the process.

Product water is stored and after pH adjustment, pressurized to feed the lines. The system has 48 membranes and membrane cleaning unit as well and provides Lafarge Tasluja tfactory with process water.
