Biological Activated Carbon (BAC) filters play a crucial role in modern water treatment systems. They combine physical filtration with biological processes to remove organic contaminants, improve water quality, and ensure safety. However, to get the best out of BAC filters, we need to focus on optimising their performance. This means understanding how they work, monitoring their condition, and applying practical strategies to maintain their efficiency over time. In this post,

After more than 20 years in water treatment, Peta Thiel has seen every “next big contaminant” come and go — from algal toxins and DBPs to endocrine disruptors and now PFAS. As Founder and Principal Chemist at Research Laboratory Services (RLS), she helps councils, utilities, and engineers move beyond reactive decision-making and into evidence-based, practical solutions that actually work. This blog shares Peta’s journey, her approach to filtration media analysis and treatmen

Is your BAC still doing the job you think it is? As carbon ages, performance shifts in ways that iodine number alone can’t capture. This blog introduces BAC Aging Profiles and the key indicators that help operators understand true in-service performance.
