Minimum Liquid Discharge Treatment
Minimum Liquid Discharge (MLD) is an approach aimed at reducing waste discharge from diverse industrial wastewater treatment facilities. This process involves recycling wastewater within the system to minimize environmental discharge. MLD systems, characterized by their complexity, demand meticulous design and monitoring for optimal effectiveness. Typically, they complement other water treatment methods to enhance environmental conservation and resource recovery, targeting a wastewater coverage of over 70%.
About the MLD Process
The MLD (Minimum Liquid Discharge) process encompasses various methods. Zirsakht Tadbir Arian Company primarily utilizes the Reverse Osmosis (RO) method as the core MLD technique, which can be complemented with pre-treatment and post-treatment methods tailored to the specific characteristics of the incoming wastewater.
We specialize in the design and implementation of cutting-edge MLD and RO systems that yield exceptional water recovery rates within MLD systems. Our RO systems encompass both conventional RO and Batch RO technologies.
Batch RO (BARO)
BARO (Batch RO) is a new type of closed-loop reverse osmosis system that operates semi-batch, taking advantage of dead-end filtration. In this batch RO process, the feed is continuous, while the reject stream or concentrate is recirculated internally to provide turbulent flow and prevent salt precipitation.
The BARO concentrate is recirculated to the feed until one of the three objectives is met:
Conductivity reaches a preset set point.
The maximum working pressure, as defined above, is reached.
The expected conversion is obtained.
and then purged from the system by entrainment with the influent water itself.
Features and Advantages of BARO:
Maximum Recovery (at least 15%-30% more than conventional RO)
Less Brine Waste
Greater Reliability through reduced fouling and Scaling
Unmatched Flexibility
Less Energy
to precipitate out metals, the materials that may cause hardness, and silica.
to help facilitate the precipitation, flocculation, or coagulation of any metals and suspended solids
to concentrate secondary solid waste after pretreatment or alongside an evaporator
To remove all the leftover trace amounts of suspended solids and prevent fouling, scaling, and/or corrosion
To remove the bulk of dissolved solids from the water
To further concentrate the reject RO stream or further reduce waste volume
For vaporizing water and other remaining liquids before crystallizer.
To boil off any remaining liquid and produce a dry, solid cake ready for disposal
