Vitasoy International Holdings Limited

• Industry: Food & Healthcare Devices

Client's Profile

• Established in 1940, Vitasoy International Holdings Ltd is one of the largest beverage producers and distributors in Hong Kong. The Group's two leading brands are VITASOY and VITA.

Client's Needs

• The client operates a beverage factory in Tuen Mun, New Territories. It has a wastewater treatment plant (WTP) for treating waste liquid before its discharge to public sewers.

• The client wished to enhance the WTP system to further improve its wastewater treatment.

• Preliminary studies showed that there was room for improvement in the WTP's treatment of soluble organic substances.

HKPC's Services/Solutions

• HKPC obtained information on the quantity and flowing pattern of the wastewater, and collected samples for laboratory analysis to identify the best treatment method.

• The MBR was found to be the most cost-effective solution to address this problem.

• The MBR uses just one-fifth of the space required by conventional biological systems, overcoming the space limitations of the client's factory.

• HKPC conducted an on-site pilot test to demonstrate results of the treatment. The operating costs were acceptable to the client.

• The project schedule was very tight and HKPC completed the design and installation of a full-scale MBR system within 10 months.

Productivity Achievements

• With the installation of the MBR system, the client has achieved its objective to further improve the WTP's soluble organic substance treatment under space constraints.

• The client is now considering the possibility of recycling the effluent.
