Progressive Recovery
Water Recovery & ZLD
Recover Early. Recover Often. Evaporate Last.
About Us
Progressive Water Recovery Strategy
Our ZLD systems are built on a multi-stage recovery philosophy, where water is extracted at multiple points.
Higher overall recovery
Reduced steam consumption
Lower operating expenditure
Improved plant reliability
Biological Treatment & Solid Separation
The first recovery step starts with stabilised biological treatment and solid-liquid separation.
Removes bulk organic
load
Produces stable feed for membrane systems
Prevents fouling and process shocks
Three Stage Reverse Osmosis (Primary Recovery)
In textile ZLD systems, wastewater contains high dissolved salts (TDS). Attempting very high recovery in a single RO stage increases fouling, scaling, and energy consumption. We design and integrate three-stage reverse osmosis systems that recover water progressively.
How It Works
Stage 1 : Primary RO
Recovers the bulk of reusable water
Stage 2 : Secondary RO
Treats first-stage reject to recover additional water
Stage 3 : Tertiary RO
Extracts maximum possible water before evaporation
Key Benefits
- Higher overall water recovery
- Reduced membrane fouling and scaling
- Optimised energy consumption
- Extended membrane life
- Lower load on MEE and reduced operating cost
The Differentiator
Fourth-Stage Recovery
Conventional ZLD systems send RO reject directly to evaporation. Our approach introduces an additional recovery layer to extract more water before thermal treatment.
Saturator
We treat RO reject water using a Saturator followed by Ultrafiltration (UF) as a pre-conditioning step before routing it to RO-4 for further recovery. This process reduces silica, hardness, alkalinity, and organic load-helping protect downstream membranes and extend their operational life.
- Reduces silica, hardness & alkalinity
- Lowers organic load before RO-4 recovery
- Enhances membrane life and system efficiency
Ultrafiltration (UF)
We design and integrate Ultrafiltration (UF) systems as a critical polishing and protection step within the treatment train. UF acts as a physical barrier, removing fine suspended solids and colloidal matter.
- Removes suspended solids and colloids
- Protects NF membranes
- Improves reliability
Fourth-Stage Recovery: UF + NF for additional water extraction
Nanofiltration Membrane Selectivity
Nanofiltration (NF)
We offer Nanofiltration (NF) systems to extract additional reusable water from high-salinity streams before thermal treatment. NF membranes selectively separate multivalent salts and organic compounds.
- Selectively removes multivalent ions
- Allows partial salt recovery
- Produces additional reusable permeate
RO4
We design and integrate Ultrafiltration (UF) systems as a critical polishing and protection step within the treatment train. UF acts as a physical barrier, removing fine suspended solids and colloidal matter.
- Removes suspended solids and colloids
- Protects NF membranes
- Improves reliability
Engineering Difference
Why Fourth-Stage Recovery Matters
We are an engineering-driven company with a process-first mindset. Before selecting technologies, we conduct thorough analysis to design systems that perform consistently in real conditions.
"Not equipment templates - but solutions engineered around your specific wastewater behaviour."
This step transforms ZLD from a compliance solution into an efficiency-driven system.
Reduces volume sent to MEE
Cuts steam and energy consumption
Lowers operating costs
Improves overall recovery percentage
Reduces load on thermal equipment
