Rugao Honghao

This project involved the construction and operation of a wastewater treatment facility with a capacity of 3,500 tons per day. The treatment process features technology designed to treat various types of water-soluble heavy metals.

Project Location Rugao ETDZ, Rugao City, Nantong City, Jiangsu Province, China
Project Company Rugao Honghao
Wastewater Treatment Type Heavy metal wastewater
Total Investment Amount
up to 31 May 2014
Approximately HK$62.6 million
Initial Commencement
Date of Concession Period
15 November 2011
Highlights Our acquisition of this facility marks our expansion into the treatment of heavy metal wastewater. This facility requires a specialised chemical treatment process but typically provides higher profit margins in comparison to municipal and industrial wastewater treatment

(1) The Rugao Honghao Facility became commercially operational in January 2012.
(2) The Rugao Honghao Facility was only acquired by our Group in February 2013 and thus we were not involved in the design and construction of this project.

Treatment of heavy metal wastewater

The Rugao Honghao Facility only treats heavy metal wastewater discharged from the factories operating in the Rugao ETDZ. The wastewater treated by Rugao Honghao Facility primarily consists of water-soluble heavy metals such as copper, nickel, chromium and zinc. The treatment process is different depending on the chemical properties of the pollutants in the wastewater and must be applied through varying sequences of chemical reactions in separate chemical tanks. The treatment process at the Rugao Honghao Facility requires more chemicals than our other two wastewater treatment facilities due to the nature of the wastewater it treats.
