Sludge Management

Background  Sembcorp operates more than 10 wastewater treatment facilities worldwide;  Sembcorp uses belt press or centrifuge to achieve 8-12% solid content and uses dryer to achieve 70-90% solid content with a high consumption of energy in the form of steam;  High organic content and low inorganic content in the waste sludge;  Power consumption for belt press is about 70 kWhr/ton dried sludge;  Power consumption for sludge dryer is about 390 kWhr + 2 ton steam for 1 ton dried sludge;

Objective Steam (ton)  Reduce energy consumption of bio-sludge 20 drying at least 20%; 12  Reduce energy consumption of sludge 15 treatment  Recover energy from bio-sludge 10 TRL > 7 11.8

Ash Management

Background  Sembcorp operates two woodchip plants and one industry & commercial waste to energy plant in Singapore.  The bottom ash generated is landfilled in Pulau Semakau.  If the bottom ash can be converted to resources, life time for the only landfill area can be avoided.

Objective  To repurposing the bottom ash from incineration plant  The overall cost is lower than existing disposal cost  TRL > 7

Service Corridor Inspection

Background  Service corridor is a designated space in Jurong Island where various transmission pipelines are located.  No proven autonomous leak detection method in open areas.  Visual inspections to spot for damage, corrosion etc are generally limited to the ground area. To inspect upper tiers of the service corridor, additional equipment is needed in the form of erecting scaffolding, using a boom lift or installing permanent platforms for personnel access.

Objective  To develop robotics / autonomous unmanned devices, mounted with one or more sensors, be deployed round the clock to detect leakage and conduct visual inspection.  TRL > 7

Low Grade Heat Recovery

Background  Receiving condensate return from customers and needs to reduce the temperature from 105 deg C to below 40 deg C.  Existing system heat exchanger is used to heat up hot demin for steam generation.  There is still excess low grade heat.  Explored solutions required heat rejects.

Objective To develop a robust low grade heat recovery system which allows Sembcorp to maximise the utilisation of the low grade waste heat and at the same time maximise the potential income to Sembcorp.  TRL > 7
