Stripping Ammonia in Anaerobic Digesters

GIVEN its high population density, coupled with the demanding environmental standards enforced by the Environmental Protection Department, it is not surprising that Hong Kong served as the incubator for our process to remove ammonia from wastewater. What has resulted is a novel thermal ammonia stripping technology, which has low operating costs, high standards, and a small footprint.

Since 1997, the technology has been applied to both leachate from landfill sites, as well as the side-stream flows from an anaerobic digester (AD). While highly focused on the needs of Hong Kong, the technology is gaining momentum in other countries, where environmental compliance is a serious issue to address. It is also moving from leachate cleanup applications into AD.

To many engineers not involved with AD, the problems caused by ammonia may come as a surprise. It is well known that ammonia is toxic to fish and humans (sniff that floor cleaner if in doubt), so it should not be unexpected that many bacteria are similarly stressed.

An ever-increasing demand for resources, a growing population, a greater public awareness of the effects of mass pollution and increasing costs, all highlight the need for efficient natural resource management. In this note, published in June 2019 issue of the World Fertilizer magazine, Dr. Robert Eden discusses the advantages and disadvantages of the technical options that have traditionally been employed for the removal and recovery of ammonia from wastewater. In the paper, he discusses the use of heat as a mechanism for the removal of ammonia and its possible recovery, providing a cost-effective option for retrieving a resource which, while valuable, can result in significant environmental damage if not adequately treated. The paper highlights the practical implementation of the technology at several sites in Hong Kong and offers suggestions as to how the technology not only ensures adequate treatment of wastewater but could also convert a potential pollutant into a commercially viable resource. Read a full article here
