TORAY ROPUR Antiscalant Case Study


Project Overview

Huber Group is leading manufacturer of Ink in World. They have multiple plants in worldwide. Unit in Vapi has effluent generation of around 2 MLD and after treatment it was discharged in to CETP on chargeable bases. Due to their corporate policy and continues failure in CETP drainage line they have to install ZLD at Vapi facility.

Benefits to End Customer

They used to face frequent caulking of membranes & had to clean it once in a week even after maintaining a regular dosing. Jay Water Management suggested TORAY “ROPUR” antiscalant, deciding the dosing PPM based on projection depending on the water analysis & the system design. Surprisingly after changing to ROPUR, dosing reduced by 20% & the cleaning frequency reduced by 5 times reducing their OPEX as well as effluent generation due to cleaning cycles.
