Wastewater reuse is a long-established practice used for irrigation, especially in arid countries. Reusing wastewater as part of sustainable water management allows water to remain as an alternative water source for human activities. This can reduce scarcity and alleviate pressures on groundwater and other natural water bodies.
Clean water source is always concerned in all aspects of production and life.
Today, with the development of urbanization, climate change, clean water is running out. Therefore, saving water resources is very necessary.
The best solution now is to recycle water / reuse water. Water recycling is reusing treated wastewater for beneficial purposes such as agricultural and landscape irrigation, industrial processes, toilet flushing….
Water is sometimes recycled and reused onsite. For example, when an industrial facility recycles water used for cooling processes.
Recycled water can satisfy most water demands, as long as it is adequately treated to ensure water quality appropriate for the use.

Wastewater reuse system using Ultrafilter
Water recycling offers resource and financial savings. Wastewater treatment can be tailored to meet the water quality requirements of a planned reuse, in which using Ultrafilter (UF), Ro-EDI technologies are the common solution applied to treat wastewater.
At present, Eratech has completed the wastewater reuse system for the ON Semiconductor Vietnam.
The treated water meets QVCN 01-2009/BYT.
In addition, Eratech has operated a reuse wastewater treatment system in An Nghiep Industrial Park in Soc Trang for the purpose of reusing part of the water for the operation of the plant.
