Case Study - Zero Liquid Discharge (ZLD) Application
Applied Water Solutions was contacted by a client who planned to move their manufacturing facility to an area where there is strict limitations on water discharge. Working close with the client we created a process flow diagram (PFD) using multiple water purification technologies that provided pure water generation, water recycling capabilities and offsite disposal of solids. From the PFD we then ...

Why Zero Liquid Discharge Systems Are Important?
Zero liquid discharge (ZLD) is a strategic wastewater management system that ensures that there will be no discharge of industrial wastewater into the environment. ZLD is achieved by treating wastewater through water recycling and then recovery and reuse for industrial purpose. Hence it is a cycle of closed loop with no discharge. Although ZLD is a costly process, it paves the way for economic ...
