HRS helps AD plant tap into additional heat from existing CHP
January 22, 2020 Categories: Environmental - Opinion Piece

Operators of anaerobic digestion (AD) plants know how important it is to optimise energy use across all stages of the process. That is why many recapture as much heat as possible for reuse elsewhere, including from the hot exhaust gases generated by the combined heat and power (CHP) engines which turn the biogas from the…

Understanding and preventing heat exchanger fouling
September 18, 2019 Categories: Environmental - Opinion Piece

When operating in exceptionally challenging conditions, or handling difficult materials such as sewage and wastewater sludges, even the best designed heat exchangers will be susceptible to fouling. Understanding the different types of fouling and what causes them will help engineers and operators pick the best type of heat exchanger for their particular application and keep…

Spiral or corrugated tube heat exchangers – which is best for wastewater treatment?
September 3, 2019 Categories: Environmental - Opinion Piece

Since the first spiral heat exchanger was proposed back in the 19th century, they have become synonymous with the treatment of slurries and wastewater. However, in many situations the performance of a corrugated tube heat exchanger is equal to or better than that of a spiral design. Corrugated tube designs also provide a number of…

Product-to-product heat recovery
July 16, 2019 Categories: Environmental - Opinion Piece

Wastewater, sewage, effluents and sludge are useful sources of energy with the potential to heat (or in some circumstances cool) other products or materials in industrial processes. The DTR Series of double tube heat exchangers from HRS is designed to maximise direct (product-to-product) energy recovery from such low viscosity materials, allowing valuable heat to be…
