What drives us

Safety and regulatory command, built into every project.

A relentless ALARA culture and deep command of nuclear and environmental regulation keep your operations compliant and audit-ready.

01

Safety First

Rigorous radiation protection and a relentless ALARA culture underpin every project we deliver.

02

Regulatory Excellence

Deep command of nuclear and environmental regulation keeps your operations compliant and audit-ready.

03

Integrated Expertise

Engineering, technical and technological capability under one roof, from first concept to final closure.

04

Sustainability

We minimise waste, recover value and protect the environment for the generations that follow.

Four technology divisions

One unit-operation toolkit, applied across industrial, nuclear and waste streams.

Precipitation, ion exchange, oxidation, membranes and evaporation — applied to industrial effluent, refinery spent caustic and liquid radioactive effluent, with a fourth division for everything that is not waste-liquid.

Industrial Waste-Liquid I DIVISION I

Industrial Waste-Liquid

Sector-by-sector treatment of non-radioactive effluent — physical–chemical, biological, thermal and zero-liquid-discharge trains.

Phys–chem Biological Thermal / ZLD
View division
Spent Caustic II DIVISION II

Spent Caustic

Destruction of sulfidic, phenolic and naphthenic spent caustic from refinery and olefins scrubbing — by advanced oxidation and wet air oxidation.

AOP WAO Sulfide → sulfate

Nuclear Waste-Liquid III DIVISION III

Nuclear Waste-Liquid

Liquid radioactive effluent management — co-precipitation, selective ion exchange, evaporation and immobilisation below release limits.

Co-precip Selective IX Immobilise

Waste Management IV DIVISION IV

Waste Management

Everything that is not waste-liquid — solid, hazardous, gaseous and conditioned wastes arising across both industries.

Advanced laboratory

ISO/IEC 17025-aligned fingerprinting of every stream — 120+ parameters in scope.

Piloting & R&D

Mobile pilot skids prove the route on the client’s real effluent before EPC.

On-skid manufacturing

Factory-built, FAT-tested skids and containerised plants, shipped ready to connect.

Standards & codes

ISO, ASME, PED and IAEA — compliance engineered in under the ALARA principle.

Technology toolkit

Each plant assembled from a proven set of unit operations.

KEMISTA selects and sequences technologies case by case to match the effluent, the discharge consent and the client's reuse and recovery goals.

Open selection matrix
T-01

Physical–Chemical

Coagulation, flocculation, DAF, clarification, filtration and ion exchange.

T-02

Biological

Aerobic AS/MBBR/MBR and high-rate anaerobic UASB/EGSB for organic load.

T-03

Membranes

Ultrafiltration and reverse osmosis for separation and reuse-grade permeate.

T-04

Thermal & ZLD

Evaporation, crystallisation and brine concentration to near-zero discharge.

Industries we serve

Wherever water, waste and compliance are mission-critical.

Sustainability

We minimise waste, recover value, and close the water loop.

Anaerobic stages turn organic load into biogas, nitrogen is recovered as fertiliser, salts are crystallised for reuse, and zero-liquid-discharge trains return virtually all water to process.
