In Textile Sector, specially in Terry Towel & Bath Robe Industry; they use Zero Twist Threat for Weaving of Towel Fabric which is being done by wraping the thread on PVA Noddle. This PVA noddle afterwards dissolved in the water and discharged into the wastewater. If we go for wastewater treatment and then recycling of this wastewater, then this PVA clogs the RO Membranes permanently. Anyone has any process how to remove this PVA from the wastewater prior to RO?
The quantity of this PVA enriched water is not high say 60 m3/day.
