With space missions already in the planning to send humans to Mars, there is an urgent need for more efficient water reuse on-board spacecraft. Reducing the total volume of water needed to sustain long-term space travel means lighter payloads at launch, or the ability to carry more cargo. The AELISS project, a collaboration between the University of Alicante and the University of Puerto Rico, aims to improve the efficiency of such water recycling systems in microgravity conditions.
Last month, NASA launched a cargo ship carrying an experimental system on board used to study the oxidation of ammonia under microgravity conditions to convert urine into water on the ISS. This research project is a collaboration between researchers at the University of Alicante in Spain and the University of Puerto Rico, titled «Ammonia Electrooxidation Lab at the International Space Station (AELISS)».

Consuming such ammonia-contaminated water can cause damage to the internal organs, lungs, brain, anaemia, cough, irritation in eyes and pain, according to health experts. 3 ways to remove ammonia from water [Representative image] | Photo Credit: iStock Images
Key Highlights
Nitrifying bacteria treat ammonia-contaminated water through biological processes.
In ion exchange method, the ammonium ions contained in the water get exchanged with the ions contained in clinoptilolite.
New Delhi: High ammonia levels in the river Yamuna, a major source of potable water for Delhi residents, led to a temporary closure of Wazirabad, Chandrawal and Okhla water treatment plants in the national capital, disrupting water supply in some parts on the city on Tuesday.
Jura Cement to install regenerative thermal oxidation system from Dürr Written by Global Cement staff
13 January 2021
Switzerland: Dürr is supplying a regenerative thermal oxidation system (RTO) to Jura Cement Fabriken integrated plant in Wildegg as the main stage in its air pollution control system. The upgrade is intended to enable the cement producer to comply with anticipated lower gas emission limits for carbon monoxide, hydrocarbons, and ammonia (NH
3). The supplier says its solution combines Dürr’s Ecopure RTO multiple-chamber principle with an optimisation of the existing process technology in the calciner. It is scheduled to start operation in 2022.
