Minimum Qualification


DOCTOR OF PHILOSOPHY (PHD)




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).
