James Hartley
Chartered Water & Wastewater Process Engineer
CEng MIChemE · BEng (Hons) Chemical Engineering · 18 years in industrial effluent treatment
James Hartley is a chartered process engineer (CEng MIChemE) with 18 years of experience designing and commissioning industrial water and wastewater treatment plant. He has led process design on dissolved air flotation (DAF), membrane bioreactor (MBR) and moving-bed biofilm reactor (MBBR) installations for food and beverage, dairy, and municipal clients in the UK, Ireland and the Gulf.
His focus is pragmatic, standards-led design: sizing equipment against real load data, hitting discharge consents reliably, and keeping whole-life energy and chemical costs down. James writes MCBA's systems and equipment guides to translate that field experience into clear, decision-ready reference material.
Areas of expertise: Dissolved air flotation, Membrane bioreactors, MBBR, Coagulation & flocculation, Effluent compliance, Process commissioning
