ARISEO WATER TECH has an unparalleled depth of experience in zero liquid discharge (ZLD), which include more than 160 installations, including stand-alone thermal/evaporative processes, membrane processes, or hybrid systems.Zero Liquid Discharge(ZLD) At a Glance
Thepower industryas well as oil & gas, chemical, petrochemicals,miningand other industries generate large volumes of waste water that must be managed. Commonly these wastewaters are discharged via a plant outfall to a surface water body, an evaporation pond, or in some cases deep well injected. However, there are growing environmental concerns regarding such discharge practices, which has resulted in the development of Zero Liquid Discharge (ZLD) processes.
Zero liquid discharge can be defined broadly as a process for maximum recovery of water from a waste water source that would otherwise be discharged. This water is beneficially reused and the salts, and other solids contained in the waste water are produced and generally disposed in a landfill.
The drivers for zero liquid discharge include a growing concern by the public about the impact of such discharges on the environment, and in many areas of the world, water is a scarce resource. Such concern is resulting in increased regulation and limitation of waste water discharges. Even without regulatory push, many companies in various industries are mandating initiatives for reducing water discharge by recycle reuse, as well as ZLD, to reduce their environmental footprint and improve sustainability.

A ZLD treatment system utilizes advanced technological water treatment processes to limit liquid waste at the end of your industrial process.
After the concentration step is complete, the next step is generating a solid, which is done through thermal processes or evaporation, where you evaporate all the water off, collect it, and reuse it.
Application industries are also Sugar, Distillary, Process, Textiles, Dairy, Semicoductor, Chemical, Pharma.
Water is a precious resource and its demand is growing exponentially. Water quality and environmental regulations are continuously evolving, requiring industries to review their water management strategies. Zero Liquid Discharge (ZLD) is increasingly being adopted by industries. However, all of these approaches have limitations due to high capital, maintenance and/or operational costs. This publication discusses the basics of ZLD as well as the role of reverse osmosis (RO), membrane technology in ZLD applications. The paper also reviews key applications, their challenges and cost-effective resolution approaches through the use of RO.
To fully utilize all the industrial water produced, or that would otherwise go to waste streams, zero liquid discharge (ZLD) is necessary. Not all systems are created equal and – in addition to upgrades – may need a custom ZLD design to suit your application. A ZLD treatment system utilizes advanced technological water treatment processes to remove dissolved and suspended contaminants from industrial waste streams. This technology then concentrates and crystallizes the contaminants into a solid waste so nearly 100% of your original water can be recycled or reused for boilers, cooling towers, process feeds, etc. In fact, this recycling process allows for a significant reduction in blowdown and chemical usage, which will further reduce your sludge volumes and decrease operating costs significantly.
