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 valorisation 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…

Pumps are an essential part of many food processing lines: not just for liquids, but also viscous materials such as spreads and dips, and materials containing solids such as fruit and vegetable mixes. Using the wrong pump can have expensive consequences in terms of both potential damage to products or equipment, or higher than expected…

The management and treatment of manures and slurries from livestock production is becoming an increasing issue around the world. The potential of manure to cause environmental harm and contribute to climate change when not correctly stored, handled or applied is significant. However, manures and slurries also represent a valuable resource and can return valuable crop…

Thanks to tighter environmental regulations and greater public awareness, companies are increasingly looking to reduce or eliminate the waste that they produce. In recent years, Zero Liquid Discharge (ZLD) has become an important waste reduction technique, but its potential in dealing with hazardous waste streams has not been fully appreciated until now. One of the…

At BioCycle REFOR18 stand 38, HRS Heat Exchangers will be demonstrating the crucial role that heat exchangers can play in improving the overall efficiency of biogas plants: from pre-heating feedstock to concentrating and pasteurising digestate. HRS Heat Exchangers provides a wide range of dedicated heat exchangers for the anaerobic digestion sector around the world, including…

At WEFTEC 2018 New Orleans, stand 2357, HRS Heat Exchangers will demonstrate the trial version of its unique effluent Concentration System for the first time ever in the US. The trial system enables plant operators to measure how much their effluent waste volumes can be reduced before committing to a full-sized system. With the trial-size…

When treating wastewater, sludge and digestate, it can be beneficial to reduce the volume of material or increase the solids content. Mechanical dewatering via a centrifuge or belt press to separate solids and liquids is standard for the water treatment and anaerobic digestion sectors – but what if you want to further reduce the water…
