Part 1 Heat below 120 °C: the economics of low-temperature recovery 9 Mar 2026 Part 2 Biogas from municipal sludge: size the digester before the business case 14 Apr 2026

28 Jul 2026 Biogas to power, heat and turquoise hydrogen The anaerobic reactor makes the fuel. What happens next — CHP engines, hot water, and methane pyrolysis to hydrogen with solid carbon — decides what the fuel is worth. Energy · Biogas · Hydrogen · Wastewater

6 Jul 2026 Industrial wastewater: choosing the treatment train Municipal works treat one wastewater; industry produces thousands. The technology list is long — the discipline is characterising the effluent before choosing from it. Industrial · Wastewater · Water treatment

15 Jun 2026 Spent caustic: the refinery stream nobody wants Sulphidic, phenolic or naphthenic — spent caustic is small in volume, brutal in strength, and expensive to get wrong. The treatment routes, compared. Industrial · Wastewater · Refining

18 May 2026 RO or thermal? Desalination selection in Gulf conditions Gulf seawater is hot, saline and biologically active. The textbook case for membranes weakens here — but it does not collapse. A selection method, with numbers. Desalination · Water treatment · Energy

4 May 2026 Nuclear wastewater: treatment under a different discipline Radioactive effluent treatment uses familiar unit operations — filtration, ion exchange, evaporation — governed by an unfamiliar rule: concentrate and contain, never dilute and disperse. Nuclear · Wastewater · Industrial

14 Apr 2026 Energy at the works — part 2 of 2 Biogas from municipal sludge: size the digester before the business case Sludge-to-energy proposals fail at the same three numbers: volatile solids, destruction rate, and what the gas displaces. Get those right and the rest is procurement. Energy · Biogas · Sludge · Wastewater

2 Apr 2026 Membrane desalination: seawater, brackish water and the plants between Reverse osmosis now carries most new desalination capacity worldwide. Seawater and brackish duties share the membrane — and almost nothing else. Desalination · Water treatment · Membranes

20 Mar 2026 Thermal desalination: what MSF and MED still do best Membranes won the new-build market; the thermal fleet still makes a large share of the Gulf's water. Where distillation remains the right answer, and how to review one honestly. Desalination · Energy · Water treatment
