1. Learn about Zero liquid discharge – ZLD.
Zero liquid discharge “Zero liquid discharge – ZLD” is understood as the wastewater treatment process at the end of the production process. Here, wastewater is thoroughly treated to recover maximum clean water.
The clean water obtained meets the standards for reuse/recirculation into the production process. The final waste of the ZLD process is in the form of sludge or solid. It is burned, buried or used for another industrial purpose.
Looking at the brief description of the ZLD process, we can also see the positive impacts it brings. Such as:
1.1. Benefits of ZLD.
- Save production water and water purchase costs
- Save water treatment costs and monitor wastewater discharge to meet standards
- Improve production water quality without adding an input water treatment system.
- Directly control water quality
- Save production area for the factory
- Conserve water resources
- Protect the environment
Therefore, the phrase “Zero liquid discharge” has been receiving a lot of attention recently. Especially in the manufacturing industry because of the values it brings.
1.2. Factors promoting ZLD.
With increasingly strict regulations on discharge standards, ZLD is receiving a lot of attention. Not only in countries with water shortages, but also in most countries in the world. It helps businesses reduce water treatment costs and fines for substandard water treatment regulations.
Some new regulations on discharge and strict water treatment related to reuse in Vietnam and some countries in the world. The new rules aim to minimize pollutants to the environment. From there, ZLD becomes the main and necessary water treatment solution for manufacturing plants.
It will be difficult to find a suitable ZLD system for your facility. The water treatment system is both environmentally friendly and cost-effective. The requirement is compatible with the production system. Especially under the high standards for the quality of water after treatment, it further limits the suitable technologies.

2. Who is the best supplier of ZLD system?
Your manufacturing facility wants to become a ZLD factory, you are asking the question “how to find a good company for equipment and technology in the process of zero liquid discharge?”. Where is a reputable company that can install a new system or support your factory to upgrade the current water treatment system to meet ZLD standards?
The increasing demand is also the time when suppliers need to do their job well to meet consumers. To design, supply, construct and complete a water treatment system that does not discharge liquid waste requires an environmental unit with extensive experience in the field of recycled water treatment.
Understanding water treatment techniques and constantly updating advanced technologies in the world will help suppliers of the ZLD “no liquid discharge” water treatment system to be confident in designing and implementing plans.
However, to evaluate the effectiveness of the design plan, it is necessary to have actual data on the ZLD system. That means it is necessary to have equipment to run tests in water treatment. From there, the effectiveness of each water treatment measure/technology can be evaluated.
We are a wastewater treatment unit and we provide “Zero liquid discharge (ZLD)” water treatment system. Therefore, we will not rank our partners and competitors in the Vietnamese market. But we are confident that TVTS is the leading unit in the field of supplying and operating 100% recirculating wastewater treatment systems for production in Vietnam and the region.
