JEC Hong Kong was recently awarded a contract from Drainage Services Department for the Main Works Stage 1 of Shek Wu Hui Effluent Polishing Plant. Operating for more than 30 years, the project aims to increase the treatment capacity which is approaching its maximum design capacity of 93,000m3/day with modern technologies.
The works include installation works and testing and commissioning of the electrical and mechanical sludge treatment facilities (including sludge dewatering building, combined heat and power building, sludge digesters, biogas holding tanks etc.); ultraviolet system and associated pumping station and the associated systems. To enhance its environmental performance, JEC will also be the first to install thermal hydrolysis pre-treatment system and sidestream treatment facilities in Hong Kong.
The improvement scheme of Stage 1 will increase the treatment capacity by 35,000m3/day, and eventually increase to 190,000m3/day upon completion of all stages. The project has commenced in late October and is expected to be completed in 2024.
JEC’s joint venture partner Trane Hong Kong (TYS) was awarded the Innovative Energy Project of the Year Award for the Asia-Pacific Region by the Association of Energy Engineers® in September. An advocate of the Government’s climate action plan, TYS pioneered in adopting the leading green technology from the US in its new generation chiller, coupled with energy-saving refrigerant and energy simulation software that achieves superior performance in energy efficiency. The remarkable energy saving and carbon emission reduction by the chiller have been well proven in buildings such as hospitals, clubhouses, commercial buildings and institute complexes, saving up to 2,837 MWh per year which represents the reduction of 1,986,500 kg CO2/ year (equivalent to planting 86,370 trees).
JEC with its joint venture partners was recently awarded the contract from Environmental Protection Department to design, build and operate the Organic Resources Recovery Centre Phase 2 (O·PARK2).
O·PARK2 will locate at Sha Ling in North District and will be able to treat 300 tonnes of food waste daily and produce biogas. In addition to providing electricity and heat for the facilities in O·PARK2, the surplus biogas will be used for production of town gas or electricity to be fed into the power grids of the power companies. Furthermore, O·PARK2 will produce about 10,000 tonnes of compost annually, of which some will be reserved for use by government departments, farmers and members of the public for free.
With the commissioning of O·PARK2 in 2022, the decrease in use of fossil fuels for electricity generation together with the reduced amount of organic waste being sent to landfills will prevent the emission of some 67,000 tonnes of greenhouse gases, and reduce the amount of food waste to be disposed of at landfills by about 110,000 tonnes annually.
JEC Hong Kong secured the contract to design and install E&M systems for the Temporary Sewage Treatment Plant at Sha Tau Kok. This is part of the works for Expansion of Sha Tau Kok Sewage Treatment Works Phase 1.
To tackle the challenges on short construction period and small site footprint, the project team adopts Moving Bed Biofilm Reactor (MBBR) technology in the project. MBBR is an advanced wastewater treatment technology using specialised plastic carriers to create a surface on which microorganisms treating the wastewater are grown. It is renowned for its compactness and high treatment efficiency.
Besides, Modular Integrated Construction (MiC) technology is used during the construction of steel processing tanks in the plant. Integrated modules of steel tank are manufactured in the factory before transporting to site for installation, substantially reducing the adverse impacts of weather conditions, labour resources and site constraints, in turn significantly improves construction efficiency and site safety.
The project has commenced in March this year and is expected to be completed in May 2020. The plant will have a treatment capacity of 2,500 m3/day and become the largest MBBR plant in Hong Kong upon its completion.
Solignum, a leading wood preservative brand exclusively distributed by Jardine Distribution, Inc. (JDI) was once again awarded with Superbrands status in The Philippines. Being named Superbrands since 2009, Solignum was awarded an Emerald Trophy for the longest participation in Superbrands programme.
Solignum is a tried-and-tested timber expert brand of high-performance wood treatment products such as wood preservatives, soil termiticides, and timber decorative coatings.
JEC was awarded the contracts from Hongkong Land to upgrade air handling units (AHU) for Chater House, Exchange Square, Jardine House as well as Edinburgh Tower and Gloucester Tower of Landmark.
The project involves replacing the AHUs with multiple electronically commutated (EC) plug fans. An EC plug fan has a high-performance direct current (DC) motor which is at least 10% more efficient than a conventional alternating current (AC) motor in general. It incorporates voltage alternation within the motor, enabling speed variation in accordance with target room temperature for a more precise control and less energy consumption.
The design air flow rate of an AHU will be shared by several EC plug fans instead of a single fan. If one of the EC plug fans fails to operate, other fans can speed up to reach the required flow rate so that air-conditioning supply can remain unaffected.
To echo with the Government’s five-year target to achieve a 5% electricity saving for government buildings by 2020, JEC has been working closely with clients from commercial sector to meet their energy saving target with latest technology and products.
JEC secured a contract from CLP Power to refurbish and redesign the electro-chlorination plant for Black Point Power Station in Tuen Mun, Hong Kong. JEC will rearrange six existing modules of electrolyser cell, replace transformer rectifier units, upgrade associated inlet and dosing system, and refurbish existing chemical handling system for the electrolyser cells.
The refurbished electro-chlorination system will increase the output capacity of sodium hypochlorite by 44%, allowing a more efficient control of biofouling in power plant cooling system and facilitating operation of new power generation unit at the Power Station. The project has already commenced in February and will be completed by end 2019.
To support the Government’s carbon reduction policies to combat climate change and transform Hong Kong into a smarter and greener city, JEC was recently awarded a contract from CLP Power Hong Kong Limited for Hong Kong’s largest landfill gas (LFG) power generation project in the West New Territories Landfill (WENT Landfill). JEC will build and operate a facility to convert waste LFG to electrical energy. It will generate 10MW of electricity at full capacity. JEC will also set up supervisory control and data acquisition system for remote operation control of the facility from CLP Black Point power station located at 3km away.
Located at Nim Wan in Tuen Mun, WENT Landfill is Hong Kong’s largest landfill where some of the LFG is currently used to generate electricity for onsite facilities and waste water treatment. After the generator site is established, un-utilised LFG can be put to good use for powering over 17,000 four-person households per year. The project will be completed in December this year.
JEC has secured a contract from the Airport Authority Hong Kong for the advance works of baggage handling system primary sorter replacement project at the Hong Kong International Airport (HKIA). JEC will design, manufacture, supply, deliver, install, and test and commission for the new conveyors, electrical and mechanical works, systems works and structural steel works for baggage diversion at Terminal 1 Baggage Handling Area (including North and South sides), as well as modification works for the existing baggage handling system equipment and firmware. JEC will also provide necessary training to relevant staff and contractors of HKIA on operational and maintenance aspects of these works.
