Kelvin Water Technologies Pvt Ltd offers zero liquid discharge (ZLD) solutions for efficient wastewater management, enabling recovery of over 95% of wastewater and compliance with stringent discharge regulations. A typical ZLD treatment system includes components such as clarifiers, chemical feeds, ultrafiltration, reverse osmosis, and crystallizers tailored to specific contaminants and flow rates. These technologies help recover valuable products from wastewater and improve water quality for reuse in various industrial applications.

2. What is Zero Liquid Discharge Plant & Why is it
important in wastewater treatment?
Kelvin Water Technologies offers complete thermal and non-thermal ZLD solutions to manage
tough-to-treat wastewaters. Kelvin's proprietary evaporators, brine concentrators, and
crystallizers can help recover more than 95% of your wastewater while reducing the remaining
brine as a product or solid. Kelvin's Siever total organic carbon (TOC) analyzers help control the
quality of water to be reclaimed or recycled in semiconductor operations.
Zero liquid discharge technologies help plants meet discharge and water reuse requirements,
enabling your business to:
•Meet stringent cooling tower blowdown and Flue Gas Desulfurization (FGD) discharge
regulations.
•Treat and recover valuable products from wastewater sources.
•Better manage the generated output water.
•Control the water quality that is to be reclaimed or recycled.

3. What’s included
in a basic ZLD
treatment
system?
The exact components of a ZLD treatment system will largely depend on
the volume of dissolved material present in the waste, the system’s
required flow rate what specific contaminants are present. But in general,
a basic ZLD treatment system typically includes some type of:
•Clarifier and/or reactor to precipitate out metals, hardness, and
silica
•Chemical feed to help facilitate the precipitation, flocculation, or
coagulation of any metals and suspended solids
•Filter press to concentrate secondary solid waste after pre-
treatment or alongside an evaporator
•Ultrafiltration (UF) to remove all the leftover trace amounts of
suspended solids and prevent fouling, scaling, and/or corrosion
down the line of treatment
•Reverse osmosis (RO) to remove the bulk of dissolved solids
from the water stream in the primary phases of concentration
•Brine concentrators to further concentrate the reject RO stream
or reject from electrodialysis to further reduce waste volume
•Evaporator for vaporizing access water in the final phases of
waste concentration before crystallizer.
•Crystallizer to boil off any remaining liquid, leaving you with a dry,
solid cake for disposal
