AD of Food Waste, Hong Kong

Project: O Park 1 . Ammonia Removal

The removal of ammonia from the wastewater of an AD plant that treats food waste is important to ensure any water released to the environment is safe. This project, built on the waste treatment plant designated O Park 1 in Hong Kong, ensures that all emissions are carefully monitored. The heat from engines powered by the biogas generated in the AD tanks is used in a stripping tower to clean the wastewater prior to its release from the site boundaries.

Pillar Point Valley landfill, Hong Kong

Project: Thermal ammonia stripping system

The project included the design, installation and commissioning of thermal ammonia stripping at Pillar Point Vally landfill, Hong Kong.

The system separates the ammonia from the wastewater using heat produced by the combustion of landfill gas and works by injecting the wastewater into the top of a stripping column with air being injected at the bottom.

Thermal ammonia stripping can achieve >98% removal rates.

Project Specification

Flow rate: 685,000 gallons per day

Influent concentration: 2,500 mg/L NH3-N

Effluent concentration: <100 mg/L NH3-N

Sinarmas , Central Kalimantan

Project: Closed lagoon bioreactor

This project involved the design, installation and commissioning of a closed lagoon bioreactor on the settling lagoon of a palm oil mill owned by the Sinar Mas Group, Indonesia’s largest palm oil producer.

The brief of the project was to treat the high levels of COD found in the Palm Oil Mill Effluent (POME) and to ensure that the methane gas produced could not escape to the atmosphere. The ultimate objective is to construct a biogas power plant using the excess methane generated in the process.

The project commenced with the design phase and a period of testing to ensure that all parameters of the POME and the location were known before investment in the plant began.

Project Specification

The project was designed to treat the palm oil effluent produced from the production of palm oil, one of the staple foods of Asia and a product used in many other products around the world.

The mill handles 80 tonnes per hour of fresh fruit bunch generating 1,152m3 of wastewater a day.

It was designed to handle up to 3,000Nm3/hour of biogas, the equivalent of 4 MWe; enough bioenergy to power the entire operation leaving an excess to export. In this particular case, the biogas generated from the process is used to power the boiler.

The lagoon was designed to accommodate 60,000m3 of wastewater from a factory that processes 80 tonnes per hour of Fresh Fruit Bunch.

Project Budget

Project budget of USD $4 million.

Project delivered within the specified programme and on budget.

MMPC, Montalban LFS, Philippines

Landfill gas is a potently aggressive greenhouse gas. Methane, one of the main elements with the gas, is 21 times more effective as a greenhouse gas than carbon dioxide. Its control is therefore critical and, if it can be used, it can be converted into a carbon-neutral resource.

The landfill gas power generation project in Montalban, near Manila in the Philippines, has a total of 9MWe installed. This ensures that nearly 7,500Nm3 of landfill gas per hour is removed from the environment and converted into a useful resource, thus displacing the use of fossil fuel for generating electricity.

Project Specification

The project was designed to treat landfill gas issuing from a landfill site near to Manila. The project uses 7,500Nm3/hour of gas and generates 9MWe of electricity that can be used either on-site or exported to the national grid.

This was a turnkey project and involved the design, fabrication, project management, installation and commissioning.

Power capacity installed: 9MWe
Electricity potential: 70,000 MWh / year
