Re ECF Project: ECF 2015-52

Project Title: Mobile algal cells cleaning system for application in fresh water and marine environment

Applicant: Prof Samuel Chun-Lap LO, The Hong Kong Polytechnic University

Total Approved Grant: $1,789,980

Duration: 1/4/2016 to 31/3/2018

Project Status/Remarks: On-going

Scope:
This is a technology demonstration project which aims to meet the strong need for rapid removal of excessive algal cells, both in fresh water and marine water bodies. A mobile unit (within a truck) with an industrial high-capacity-high-throughput (HCHT) centrifuge capable of operation in continuous mode as a central piece will be built. After a prototype of the mobile unit is built, the project team will test the system in shore areas around the Plover Cove Reservoir where there is occasional dense algal growth. Efficiency of the unit as well as water quality of the effluent from the pump will be studied and monitored closely. It is envisioned that provision of this mobile unit can improve water quality in the water bodies, prevent excessive release of algal proteins from the dead cells which promote bacterial growth and also reduce chance of further excessive growth of the algae. The “algal waste” becomes useful carbon-neutral bio fuel (that can be used by diesel engines without much modification). The algal biomass can also be sued to formulate food feed for fishes and animals.

Summary of the Findings/Outcomes:
To be available upon completion of the project
