The engineer who treats water like a living system.

At the intersection of rigorous chemistry and industrial reality, Tayfun Evcil has built a career that refuses to separate theory from consequence. Water treatment isn't abstract when it's keeping a geothermal power plant online or protecting a steel mill's cooling circuit from scale.

Currently at Solenis as an Industrial Solutions Applications Specialist, he designs chemical treatment programs for some of the most demanding environments in the MEA and CIS regions — from SWRO desalination systems to high-temperature boiler circuits and large-scale cooling loops. Every program is backed by verified field data, never approximated.

Beyond the field, Tayfun builds his own tools — Python-based simulation platforms that run water chemistry models in-house, cutting the dependency on expensive third-party software. And increasingly, he uses AI not as a shortcut but as a force multiplier: faster documentation, better proposals, sharper technical reports.

Core conviction
Good chemistry begins with honest data. If the numbers aren't from the field, the program isn't real.

Three companies.
One discipline.

A career built through multinational corporations and critical industries — each role adding a layer of depth to an already technically demanding practice. From fertilizer production to geothermal water chemistry to regional industrial account management, the thread is always the same: make systems work reliably in the real world.
