- Article· Water TechnologiesHow reverse osmosis worksOsmosis, the pressure that reverses it, and why the dense layer of an RO membrane keeps salt out.3 Nov 2026Read article
- Article· Reuse & ResiliencePotable Water Reuse: Treatment Trains, Risk Frameworks and Regulatory ApproachesDirect and indirect potable reuse (DPR/IPR) are gaining regulatory acceptance globally as a drought-resilient supply source. This article reviews the treatment trains used by leading utilities, the multi-barrier risk frameworks employed, and the lessons from operational deployments in Singapore, California, and Singapore.3 Nov 2026Read article
- Article· Water TechnologiesReverse Osmosis Membrane Selection: An Engineering Guide for Water Treatment ProjectsSelecting the right RO membrane element requires balancing salt rejection, permeate flux, fouling resistance, pressure rating, and total cost of ownership. This guide walks through the key parameters, qualification testing, and the CAPEX/OPEX trade-offs relevant to seawater, brackish water, and wastewater reuse applications.3 Nov 2026Read article
- Article· Processes & OperationsCT Disinfection Control: Managing Chlorine Contact Time in Drinking Water PlantsCT (concentration × time) is the regulatory metric for drinking water disinfection efficacy. This article explains how to calculate, monitor and optimise CT under variable flow, temperature and pH conditions, with worked examples for free-chlorine, chloramine and UV systems.3 Nov 2026Read article
