Nanozeolites for Total Indoor Air Quality Control
(January 2001 - present)

There is a growing market for total indoor air quality control appliances in Hong Kong due to greater awareness of the health problems associated with air pollution. This industrial sponsored project focuses on humidity control, odor removal and remediation of volatile organic compounds from indoor air. Although adsorbent wheel dehumidifier had been employed in large-scale, industrial drying, employing the same technology for domestic use requires significant re-engineering in order to reduce its size and cost while simultaneously improving its energy efficiency. This requires new adsorbent formulation that has high adsorption rate and capacity, good regenerability and long life while constrained by cost. Nanoporous and nanometer sized zeolites were key ingredient in the new adsorbent formulation that met these criteria.
This project is done in collaboration with Prof. Mitchell Tseng (IEEM, HKUST) who is an expert in manufacturing system design, has initiated this project with industrial support from Honeywell.
1. HKUST-Honeywell JRC Technology development for sorption-type indoor air quality control.
PRINCIPAL INVESTIGATOR: Prof. Mitchell Tseng and King Lun Yeung
STATUS: Completed
SUMMARY: Efficient adsorbent mixtures were formulated for application in energy-efficient, low cost, sorption-wheel type air dehumidifier. The adsorbent capacity, rate and regenerability were tested, and adsorbent-wheels coated with the new adsorbent formulation were prepared for plant testing.
2. HKUST-Veolia Water-Anjou Recherches A membrane process for water and wastewater applications
PRINCIPAL INVESTIGATOR: King Lun Yeung
STATUS: On-going (October 2003 - present)
SUMMARY: The objective of the study is to develop membrane-assisted technology for the treatment and remediation of wastewater and production of clean water.
3. Innovation and Technology Fund Nanocatalytic systems for air and water quality control
