Chemical & Pharmaceutical

Multi-stage treatment for complex chemistry, difficult contaminants and high-recovery reuse.

THE OPERATING CONTEXT

Complex water. A considered response.

Synthesis, formulation, washing and scrubbing produce highly variable effluent. Toxic catalysts, persistent organics, dissolved metals and salts can challenge both biological treatment and membrane recovery.

Nitaneer configures physical, chemical, biological and membrane stages around the incoming chemistry. Equalization and real-time monitoring protect the treatment train, while ZLD integration addresses applications requiring concentrate recovery.

UNDERSTAND THE STREAM

The wastewater challenge

Heterogeneous, inhibitory streams

Synthesis, washing and scrubbing introduce catalysts, complexing agents, metals and persistent aromatics that can inhibit biological activity.

High dissolved salts

Chlorides, sulfates, fluorides and other dissolved ions affect settling and increase membrane scaling and osmotic pressure.

An integrated recovery loop

Where zero liquid discharge is required, biological treatment, membrane recovery and thermal concentration must work together within the site footprint.

Key treatment requirements

Neutralization and protection from toxic shock
Targeted treatment of non-biodegradable organics
Salinity, scaling and membrane fouling control
Monitoring and concentrate management for ZLD

NITANEER / TREATMENT APPROACH

An integrated treatment train.

Configured around the incoming stream, operating conditions and intended water use.

Precision physico-chemical treatment

Neutralization, precipitation, coagulation-flocculation and metal reduction protect downstream biological and membrane stages.

Oxidation and biological purification

Ozonation, Fenton or UV/peroxide processes address refractory compounds. Aerobic reactors and nitrification-denitrification treat biodegradable organics and nitrogen.

UF and multi-pass RO

Membrane separation removes fine particulates and dissolved solids, supported by feed design and automated cleaning.

ZLD and process monitoring

RO recovery can be paired with mechanical vapor recompression, evaporators and crystallizers. Inline pH, conductivity, temperature and COD monitoring supports shock-load diversion.
