In the Chemical & Energy industry, crude oil storage tanks require periodic cleaning to remove heavy sediments and sludge accumulated at the tank bottom. This process involves the use of ultra-high-pressure water jets and vacuum suction to remove the washing sewage which largely comprises of sludge, oil, and water. The waste products are then sent via tanker trucks for disposal and incineration.
As water is a significant constituent of this waste, being able to reduce the water content from the cleaning waste will be advantageous, providing a significant reduction in transportation and overall disposal costs.
A Singapore-based company is seeking a system to separate water (dewater) from sludge, and further option of incorporating in-line water treatment means including volatile organic compounds (VOCs) and pH treatment. The treated water is to be re-directed by the system for reuse as cleaning water via ultra-high-pressure jets.
Collaboration is sought with companies experienced with sludge dewatering, and capable of system integrating the water treatment and reuse functions. The preferred collaboration mode is to co-develop a POC system for evaluation, before scaling up for operations.
