Project Overview
Huber Group is the leading manufacturer of Ink in the World. They have multiple plants worldwide. Unit in Vapi has an effluent generation of around 2 MLD, and after treatment, it was discharged into CETP on a chargeable basis. Due to their corporate policy and continuous failure in the CETP drainage line, they have to install ZLD at the Vapi facility.
Benefits to the End Customer
They used to face frequent caulking of membranes & had to clean them once 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 was reduced by 20% & the cleaning frequency was reduced by 5 times, reducing their OPEX as well as effluent generation due to cleaning cycles.
