ZLD Plant – Zero Liquid Discharge Solutions for Industry
Romegamart offers fully engineered ZLD ( Zero Liquid Discharge ) plants for industrial wastewater treatment across India. Our platform connects EPC contractors , OEMs , system integrators , and project consultants to verified ZLD manufacturers at competitive factory prices , ensuring authentic and cost effective solutions.
What Is a ZLD Plant ?
A Zero Liquid Discharge plant is an advanced wastewater system designed to recover nearly 100% of water from industrial effluent and convert the remaining concentrated waste into solid residues. This ensures no untreated liquid is discharged into the environment. Industries such as textiles , pharmaceuticals , chemicals , distilleries , and food processing widely adopt ZLD systems to meet strict CPCB and SPCB environmental regulations while minimizing their ecological footprint.
How Does a ZLD Plant Work ?
A typical ZLD plant employs multiple treatment stages :
-
Pre Treatment : Removes suspended solids , oil , grease , and organic matter.
-
Reverse Osmosis ( RO ) : Concentrates dissolved solids and recovers clean water.
-
Multiple Effect Evaporator ( MEE ) : Evaporates RO reject water to separate brine.
-
Crystallizer/ATFD : Converts concentrated brine into dry salts suitable for safe disposal.
-
Condensate Recovery : Recycles recovered water back into industrial operations.
These processes enable water recovery efficiency of up to 98% , aligning with environmental sustainability goals.
Industrial Applications
ZLD plants are essential in industries such as :
-
Textile dyeing and garment manufacturing
-
Pharmaceuticals and chemical production
-
Distilleries and breweries
-
Paper , pulp , and food processing sectors
By implementing ZLD , these industries significantly reduce wastewater discharge and conserve water resources.
ZLD Plant Cost Factors
The investment for a ZLD plant depends on :
-
Effluent volume and flow rate
-
Total dissolved solids ( TDS ) levels
-
Number of treatment stages involved
-
Materials of construction
-
Degree of automation and control systems
Typical costs range from ₹40 lakh to ₹5 crore , varying by system size and complexity.
