Innovative process line for wastewater treatment

Contain, Alleviate, Create

Our project consists of processes that reduce water usage in both domestic and industrial scale with forward osmosis membrane technology

Use Case

The average household of four produces 301-575L of wastewater daily, and 30% of which are used for toilet flushing system, and further 33% of which are used for shower and bath. The amount of water used for toilet flushing could be conserved by recycle the second hand shower and bath water into a storage tank for toilet flushing. The waste water produced will be fed into an industrial waste water treatment plant. The conventional membrane reactor will be replaced by our forward osmosis membrane reactor in the waste water treatment plant; this provides cheaper and more efficient solution in processing waste water. Furthermore, all side products and draw solution used in the processes can be sustainably reused for fertilizer irrigation.

Potential

Our concept help reduces the water footprint by 30% among domestic waste water, as well as 80% in industrial waste water treatment process with the use of osmosis membrane reactor, a method which achieves high waste water treatment conversion with low energy cost and low operating pressure compare to the conventional membrane unit. Furthermore, the possibility of generating fertilizer from downstream sludge and membrane draw solution provides a reduction of overall waste-product ratio and recycle the majority of generated water onsite. The average household of four produces 301-575 L of waste water daily, by implementing this strategy we would have major water footprint reduction on a global scale.

Business Case

Our project offers great business potential for global market. The key strength of the system is the low energy consumption and the high reaction efficiency compare to the conventional membrane unit. Our major clients would be industrial waste water treatment plants whom replace the conventional membranes with forward osmosis membranes. Domestic household would also be potential clients where their bathroom could be fitted with waste water storage units for secondary shower water recycling. Our major collaborators would be Fertilizer Companies where the downstream sludge products can be further processed into fertilizer; this is system could be beneficial to local farmland by providing cheaper fertilizer irrigation service with the draw solution used in forward osmosis membrane reactor.

Objectives:

  1. To develop a domestic scale wastewater recycling stream which reduced 30% of household waste water
  2. To develop membrane bioreactor for industrial wastewater treatment with forward osmosis technology
  3. Provide strategy for further usage of the draw solution in forward osmosis reaction and sludge produced in wastewater treatment process.

What contributes to your domestic wastewater?

The average household of four produces 301-575L of wastewater daily, and 30% of which are used for toilet flushing system, and further 33% of which are used for shower and bath. The amount of water used for toilet flushing could be conserved by recycle the second hand shower and bath water into a storage tank for toilet flushing.

BBC Africa just published this article about what could be done with the downstream sludge produced by wastewater treatment plant

Discussion over a College Black Tie formal dinner -- Where the idea sparked

As a common weekly ritual in Oxford University, Fozia and I were having a four-course formal dinner in Somerville College, a college which was named after Lady Somerville (1780-1872), a Scottish science writer and polymath, and tutor of Ada Lovelace, whom is chiefly known for her work on Charles Babbage's early mechanical general-purpose computer, the Analytical Engine. Naturally, after the Latin Grace being said and high table being seated, we talked about female in engineering and their impact to the community. This was where it all begins, when we decided that we would like to start on a project together that will benefit a community with our engineering background.

The running of forward Osmosis cell- mass flux of the output is read from the balance and recorded by data logger, whereas the draw solution is recycled

Our Mission

The overall aim of our project is to drive down the water footprint across the world, in both domestic scale and industrial level. Efficient wastewater recycling loop and the most innovative forward osmosis membrane distillation technology will be introduced here for industrial wastewater treatment. Our objectives are as follows, 1. To develop a domestic scale wastewater recycling stream which reduced 30% of household waste water; 2. To develop a membrane reactor for industrial wastewater treatment with forward osmosis technology; 3. Provide strategy for further usage of the draw solution in forward osmosis reaction and sludge produced in wastewater treatment process. Our project will establish an innovative industrial process line in order to reduce both domestic and industrial water footprint, achieve high wastewater treatment conversion with low energy cost as well as reduce the overall waste-product ratio.

Our Background

Team Oxmosis is formed by a group of enthusiastic engineering and science PhD students from University of Oxford. We care intensely about life quality for people all around the world. Human Life matters, and water scarcity has become an important issue across the globe. We are here to bring you the most innovative solutions for water desalination, together with efficient water reusable strategy, our final goal is aim to drive down the water footprint across the world.
