Zero Liquid Discharge Solutions
Integrated process concepts for projects seeking high water recovery and reduced or eliminated liquid discharge.
Solution overview
Control scaling and concentrate before final disposal
PALLIND discusses membrane-based and integrated ZLD treatment routes for industrial wastewater and cooling-tower blowdown. The final process depends on verified water chemistry, recovery objectives and the required handling of salts and solids.
01
Pretreatment and softening
Reduce suspended solids, hardness, silica and other scaling risks before concentration.
02
Membrane concentration
Review RO, NF, STRO or related stages against salinity, recovery and concentrate quality.
03
Final concentrate management
Coordinate evaporation, crystallization or off-site handling with the project water and salt balance.
Project assessment
Information needed for process design
Share the project design basis so the treatment route and equipment configuration can be reviewed.
- Complete feedwater analysis, variability and temperature.
- Average and peak flow plus the site water balance.
- Required recovery and acceptable remaining liquid discharge.
- Scaling ions, silica, organics and suspended solids.
- Existing systems, energy sources, space and solids or salt disposal route.

FAQ
Before developing a proposal
Can a treatment route be selected without a water analysis?
No. The process should be selected from verified water quality, flow, operating conditions and the required outlet or recovery target.
Are treatment results guaranteed by this page?
No. Project targets and guarantees require a confirmed design basis, model selection and supporting technical documentation.
