PANBIC-H system is fluidized bed-type high load anaerobic wastewater treatment equipment which eliminates the gas-solid-liquid separation unit in the reactor used in the conventional UASB method and uses the entire reactor as the reaction space, enabling high-load operation and significantly reducing the entire equipment size, in comparison with the normal UASB method.
- High-load treatment is possible
By reducing the size of the gas-solid-liquid separation mechanism, granule retention quantity per capacity significantly increases to allow for high load than the conventional UASB.
- Saves and generation energy
Aeration power is not necessary and methane gas produced from wastewater can be reused as clean energy.
- Less excess sludge
Excessive sludge is greatly reduced in comparison with the aerobic activated sludge method.
- Saves space
Higher load per tank capacity significantly reduces the installation space in comparison with the aerobic activated sludge method.
- Faster startup
By initially putting a necessary quantity of granules, startup period can be substantially shortened.
- Easy operation management
PANBIC system ensures stable operation against load variation of wastewater, in comparison with the aerobic activated sludge method. Because removed BOD quantity is in proportion to generated gas quantity, operation status can be managed by measuring the quantity of generated gas.
PANBIC-H system consists of (1) reactor, (2) separation tank, and (3) recycle pump.
Raw water flows from the bottom of the reactor, and is dissolved into methane gas and carbon dioxide while it passes the granule layer upwards.
Wastewater contacts granules in the reactor and organic substances are removed, then the granules and treated water are separated in the separation tank.
Granules separated by sedimentation in the separation tank are returned to the reactor by the recycle pump.
- Treatment of food, chemical, oil refinement, pharmaceutical, paper/pulp manufacturing wastewater and high-concentration organic wastewater such as stockbreeding wastewater
- Pre-treatment of existing activated sludge treatment
