Water Environment Engineering Lab
Machine-translated · View original
A lab that cleans water with nanomaterials and generates energy from waste.
AboutAbout the lab
Creating safe, clean water environments with nanomaterials
The Water Environment Engineering Lab (WEEL) studies the removal of pollutants from water and the generation of renewable energy from waste.
Its targets include heavy metals such as arsenic and chromium, radioactive elements such as cesium and strontium, and antibiotics. The lab also researches recovering nutrients such as phosphorus and nitrate from wastewater.
It also works on developing bioenergy, including methane and hydrogen production by anaerobic digestion and power generation by microbial fuel cells.
The lab is a multinational research team that collaborates with scientists and engineers in Japan and other countries.
Key terms
- Microbial fuel cell
- An electrochemical device that uses the activity of microorganisms to generate electricity from wastewater and similar sources
- Anaerobic digestion
- A treatment process in which microorganisms break down organic matter to produce biogas. It is divided into four stages, and different microorganisms work at each stage
- Permeable reactive barrier
- One of the methods used to clean up groundwater. Groundwater is passed through a layer of material that reacts with the contaminants

ResearchResearch themes
Taking advantage of nanotechnology, the lab works on water treatment, resource recovery, and the production of bioenergy from waste. To this end, it synthesizes a variety of nanomaterials that are extremely small compared with ordinary materials and have a large surface area per unit volume and high surface reactivity.
Removing contamination from pharmaceuticals and other sources
This research uses iron-based nanoparticles and nanocomposites to adsorb and degrade pharmaceuticals and personal care products (PPCPs) in water. A major motivation is preventing people and animals from drinking water contaminated with PPCPs.
Improving iron nanoparticles with coatings
Unsupported iron nanoparticles aggregate and lose their reactivity and stability. By covering them with layers of magnesium, aluminum, and calcium hydroxides, the lab improves their dispersion stability in water and their ease of movement through porous media.
Predicting the transport of groundwater contaminants
The lab predicts how contaminants spread using computer models that combine chemical reactions and groundwater flow. Models based on laboratory column experiments are incorporated into the design of permeable reactive barriers.
Biogas production from wastewater sludge
This research uses anaerobic digestion, a waste and wastewater treatment technology, to produce biogas (a gas mixture of methane and carbon dioxide) from wastewater sludge.
