Zld System Manufacturer

ZLD stands for Zero Liquid Discharge, a system that is used to treat and reuse wastewater in a closed-loop system. The following are some common features of ZLD systems:
Pre-treatment: The first step in a ZLD system is pre-treatment, which involves removing solids and other contaminants from the wastewater. This is typically done using a sedimentation tank, a filter, or a clarifier.
Evaporation: After pre-treatment, the wastewater is subjected to evaporation, which removes water from the waste stream and concentrates the remaining contaminants. This is typically done using multi-effect evaporators or thermal evaporators.
Crystallization: In some ZLD systems, the concentrated waste stream is subjected to crystallization, which further removes water and results in a solid waste product that can be disposed of or processed further.
Recycling: The purified water from ZLD systems can be recycled back into the industrial process, reducing the need for fresh water and helping to conserve water resources.
Energy recovery: ZLD systems often use energy-intensive processes, such as evaporation and crystallization. However, these processes can also generate heat and other forms of energy that can be recovered and reused, reducing the overall energy consumption of the system.
Monitoring and control: ZLD systems are typically equipped with monitoring and control systems that help to optimize the performance of the system and ensure that it is operating within design parameters.
By incorporating these features, ZLD systems can effectively treat and reuse wastewater, reducing the need for fresh water, conserving water resources, and improving the overall sustainability of industrial processes.
ZERO LIQUID DISCHARGE PLANT BENEFITS & APPLICATIONS:
As Waste water recycling plant manufacturer, recover valuable resources from the wastewater which can either be sold or reused during industrial processes. Here are some examples:

Production of valuable potassium sulphate (K2SO4), fertiliser from a salt mine
Concentration of caustic soda, sodium hydroxide (NaOH) to 50 and 99% purity
Minimise coal mine wastewater treatment costs by recovering pure sodium chloride which can be sold as a road salt.
Decrease the volume of wastewater and lowers the costs of waste management.
On site recycling of water, thus decreasing the need for water intake and meeting treatment requirements.
