INDIA – The 60,000 m3/d SWRO plant at Kuthiraimozhi village in Ramanathapuram has been recommended for coastal regulation zone (CRZ) clearance. The Tamil Nadu Water and Drainage Board’s (TWAD) proposal was previously rejected by the Expert Appraisal Committee (EAC) of the Environment Ministry, owing to the location being within the eco-sensitive zone of the Gulf of Mannar Marine National Park.
The TWAD filed a modified proposal to the EAC for clearance in which the intake and brine disposal point was moved outside the eco-sensitive area. The TWAD also proposed the creation of a series of artificial lagoons filled with brine to reduce brine disposal into the sea. The artificial lagoons would be 1 meter deep so the brine could be collected and the surplus utilized either by the Tamil Nadu Salt Corporation Ltd or private salt pan owners at Periasamy Puram. The EAC expressed appreciation for the proposal model to reduce brine discharge, but urged the TWAD to explore the possibility of zero brine discharge from the plant. (The Hindu)

CANADA – Saltworks Technologies announced the first full-scale order for their Ultra High-Pressure Reverse Osmosis (UHP RO) system with Nitto Hydranautics Pro-XP1 spiral wound membranes. The first full scale industrial client is a US manufacturer of advanced materials that will use the system to achieve reduced brine production while recovering clean water for re-use. Saltworks’ Ultra high-pressure RO operates at a 50 % higher pressure than seawater reverse osmosis systems, generating half the brine volume. Saltworks started working on the UHP RO system two years ago and has since been pilot testing the system on various customer applications including mining waters, factory wastewater, ion exchange regeneration waste and cooling tower blowdown.
