Algae Research Could Help Clean Wastewater in Jordan

A Jordanian PhD student has come to Bath to investigate how our algae research could help clean wastewater in her country

As one of the most water-poor countries in the world, Jordan's current water resources are significantly below the global water scarcity line. Annual rainfall falls under 50mm in 95% of the country and nearly all the groundwater sources are being seriously overexploited.Experts are warningthat the country could soon face absolute water poverty.

Jordan's geographic location also means that refugee flow,reportedin 2014 to be over 600,000, from Syria, Iraq and Palestine puts even more pressure on the chronically scarce resources.

New ways of cutting down water wastage and overuse are in desperate demand and high on the Jordanian government's agenda. This is what has brought Mais Sweiss to Bath.

"There is no one at my university in Jordan who does algae research and only a handful of people in the whole of Jordan doing research in this field", Mais says.

Building on Roman algae

Mais is drawing on the research of our Professor of Plant Molecular Biology, Rod Scott. In 2011, he led on a project looking at the algae that grow in the city's Roman Baths.

Rod's team was looking for an algae that would have the unique characteristics that enable its large scale use in biofuel production - enough easily retrievable cell oil and the ability to survive high temperatures.

Micro-algae is a diverse group of species with many potential applications beyond biofuel. Cleaning and improving the quality of wastewater is one of these - an application which, at the moment, remains an uncharted possibility in Jordan.

Mais' research is being funded by a Jordanian government scholarship. On her return, her plan is to establish an algae research lab at her home institution, Al Balqa' Applied University.

"I came here to learn - gain new expertise and skills so I can pass them onto my own students", she says.

"Good environment to learn"

A specific requirement for Mais' funding was to pursue a field of research which would bring something new to Jordan on her return. The cross-faculty algae research at Bath stood out as an ideal match for Mais' research interests.

"Jordan offers a good environment for growing algae - the light and the temperature are ideal. But the expertise isn't there yet. This is a good environment to learn", Mais says.

Dr Tom Arnot, Senior Lecturer at our Department of Chemical Engineering and Mais' co-supervisor, is leading a major collaboration with Wessex Water, which has resulted in the foundation of a newWater Innovation & Research Centre(WIRC @ Bath).

The newly launched centre draws expertise across various faculties and departments including Biology & Biochemistry, Chemical Engineering and Chemistry amongst others.

Mais has gained from the close industry collaboration by being able to sample algal species at various wastewater treatment works operated by Wessex Water.

Tom's existing links with Jordan have also proved useful.

"It was great to be able to help Mais organise an algae sampling trip to Jordan via my colleague Dr Murad Bino, Executive Director of the Inter-Islamic Network on Water Resources Development & Management, which is based in Amman, Jordan", he said.

"Mais is also clearly benefitting from working alongside other colleagues in WIRC @ Bath."

Reduced need for chemicals

In its current form, nutrient removal from water relies on chemical treatment and the process has a big carbon footprint.

The use of algae has the potential to address both these issues, but it would also introduce additional benefits - the biomass created as a by-product could be recycled back into agriculture as a fertiliser or used as a biofuel.

Using algae and wastewater samples from both UK and Jordan, Mais hopes to isolate native microalgae that have adapted to the local environment in Jordan.

Halfway through her PhD, she is already planning future work for when she arrives back in Jordan.

"I'm interested in genetically improving the algae strains for wastewater treatment and biofuel production, but also utilising algae to produce other high value products such as β- carotene, which is a precursor to vitamin A, and omega-3 fatty acids."

Importance of water research

In 2009, Mais' university opened a cross-facultyInternational Research Center for Water, Environment and Energyin co-operation with UNESCO.

Dr. Rakad Ayed Ta'any, the Director of the centre, comments on its website about the fundamental role research plays in the effective management of natural resources.

"Research institutions can provide technical and scientific information that should be the basis for policy and decision-makers and may contribute to building national capacities to ensure a sustainable management of these resources."
