WBA Training | Managing Summer Temperatures and Biological Health
19th December 2023 @ 12:30 pm - 5:00 pm
£147.50 – £295.00
Overview
Tuesday 19th December, 12:30-17:00 GMT timezone
The training is delivered by Angela Cronjé, a chemical engineer with 20 years experience in organic waste processing on operational plants.
This training is about the effect of temperature variation on biological health and gas production for AD. AD plants are typically built with lots of insulation to keep substrate warm even in cold winter temperatures, but this can contribute to increasing tank temperatures and biological risks in the hotter summer months. Gas production can also suffer when process temperatures drop due to low ambient temperatures or failures in heating systems. Operators will gain a better understanding of how process temperatures vary, what this means for biological health and gas production and what control measures should be considered to mitigate the risk of serious biological failures.

The World Biogas Association is the global trade association for the biogas, landfill gas and anaerobic digestion (AD) sectors, dedicated to facilitating the adoption of biogas globally. We believe that the global adoption of biogas technologies is a multi-faceted opportunity to produce clean, renewable energy while resolving global issues related to development, public health and economic growth. We seek to represent all organisations working in the biogas industry at the international level across the world, including; national associations, biogas operators and developers, equipment providers, water companies, the agricultural sector, waste companies, and academic & research institutions.
Discounts available for group bookings and non-OECD countries.
