Research Scientist - Colloidal Chemistry

LNT/RS-CC/1612590

WET-Water & Effluent Treatment ICKancheepuram

We are seeking a Colloidal Chemist to advance the understanding and application of surface chemistry and colloidal behaviour in water treatment and sludge management. The candidate will study aggregation, adsorption, and particle-surface interactions, focusing on improving coagulation, flocculation, and solid-liquid separation processes.

The role involves both theoretical and applied research - developing predictive models for particle stability and designing novel flocculants or surface-active agents. The candidate will also support cross-functional teams by providing scientific insights into rheology, emulsion stability, and micro-particle behaviour.

Key Responsibilities

• Research colloidal stability and aggregation mechanisms in various water matrices.

• Develop a dedicated colloidal chemistry laboratory capable of simulating surface characteristics, particle interactions, and impurity separation mechanisms relevant to water and wastewater systems.

• Develop surface-active compounds and flocculants to improve clarification efficiency.

• Characterize particles and interfaces using DLS, zeta potential, and rheological analysis.

• Collaborate with process and mechanical teams for pilot-scale validation.

• Publish results in peer-reviewed journals and file patents where applicable.

• Support troubleshooting of plant-scale coagulation and sludge dewatering issues.

Qualifications

• Education: PhD in Colloidal or Surface Chemistry.

• Experience: ~10 years total, with good exposure to water/wastewater systems.

• Expertise in colloidal interactions, surfactant chemistry, and interfacial phenomena.

• Publications: At least 5 high-quality papers or equivalent conference proceedings; patents preferred.

• Experience with particle characterization instruments (DLS, TEM, FTIR).
