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…

HRS Heat Exchangers, Booth 8512, WEFTEC 2019 HRS Heat Exchangers will highlight its extensive range of heat exchangers and treatment systems for wastewater and anaerobic digestion at the world’s largest annual water quality exhibition: WEFTEC, when it returns to Chicago, IL this September. In particular, HRS will address the prevention of fouling and how to…

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 maximize direct (product-to-product) energy recovery from such low viscosity materials, allowing valuable heat to be…

Liquid and semi-liquid waste streams are an unavoidable aspect of many industrial processes, from energy production to food manufacturing; from chemical processing to wastewater treatment; systems which can reduce the volume and water content of such waste streams can not only cut disposal costs, but often turn a waste into a potentially valuable resource. Evaporation…

HRS Heat Exchangers, Stand G201, UK AD & World Biogas Expo HRS Heat Exchangers will showcase highlights from its extensive range of heat exchangers and treatment systems for anaerobic digestion at UK AD & World Biogas in July, with a particular focus on the benefits of removing water from biogas. If water enters a CHP…

There are a variety of tubular heat exchangers on the market, but for many applications corrugated tubes continue to be preferred over smooth ones. Matt Hale, International Sales & Marketing Director of HRS Heat Exchangers, explains why… While plate heat exchangers are still commonly used for simple viscous fluids such as water, milk and some…

As climate scientists and world leaders met in Poland in December, in the US the role that renewable energy – and biogas in particular – can play in mitigating the effects of climate change were highlighted by a report to Congress. The fourth National Climate Assessment report¹ (NCA4) was published on 30 November 2018 under…

At CHEMUK 2019 Stand F10, HRS Heat Exchangers will showcase its SI Series of multitube heat exchangers, which includes a double tubeplate to aid leak detection and prevent cross-contamination between the service fluid and product. Whether you are processing fine chemicals or treating complex waste streams, every part of the process needs to be reliable,…

Waste is increasingly viewed as a resource. From well-established practices such as recycling paper and aluminium, to the development of the circular economy, an increasing volume of resources are now being recovered from materials that were previously seen only as inconvenient wastes. Waste valorization is the process of recovering value from waste materials, for example…

HRS Heat Exchangers, Stand E12, Hall 4, SMAGUA 2019 At SMAGUA 2019 Stand E12, HRS Heat Exchangers will explain why resource and energy efficiency is just as important when dealing with wastewater streams as it is for fresh water availability. Under Article 9 of the EU Water Framework Directive (WFD), governments have a responsibility to…
