Biodegradable Flocculant (Bioflocculant)

What Is a Biodegradable Flocculant?
It is a natural polymer solution with high flocculation performance. Because it contains no heavy metals or harmful chemical substances, this flocculant biodegrades in the natural environment. Sludge compost made using a biodegradable flocculant can be recycled in a safe and environmentally friendly form.

What Is Bioflocculant?
Bioflocculant K Powder:
A flocculant derived from natural materials.
Because it is biodegradable, it does not remain when returned to soil.

Bioflocculant A Powder:
Like K Powder, this is a flocculant derived from natural materials.
A Powder itself does not have flocculation ability, but when used in combination with K Powder, it forms strong flocs.

Safety
The components of Bioflocculant are also used in food additives and similar materials, and have been shown to be physiologically harmless.

How to Use
- When flocculating excess sludge, water content 98.2 - 99%
Dissolve Bioflocculant A Powder and Bioflocculant K Powder in water to concentrations of 0.2% and 0.3% (w/v), respectively. These are referred to as A solution and K solution. As a guide, add A solution at 0.5 powder %/kg - DS relative to the sludge dry solids, DS = Dry Sludge, and rapidly stir. Then add K solution at 2.0 powder %/kg - DS and slowly stir to flocculate and settle the sludge.

*Caution
- Flocculation performance differs depending on the type of wastewater to be flocculated and the properties of the sludge it contains, such as concentration, particle size, and charge. Please confirm the optimum dosage by testing before use.
- Bioflocculant shows particularly excellent flocculation performance for sludge that is well managed as activated sludge and is being treated properly. Therefore, process withdrawn sludge as soon as possible. If withdrawn sludge is stored and becomes anaerobic, flocculation performance decreases.
- Bioflocculant may flow out into the filtrate after thickening and dewatering, but because Bioflocculant is readily biodegradable, there is no problem with returning it to the aeration tank.

Storage Method
Bioflocculant has high biodegradability, so its flocculation capacity gradually decreases due to decomposition. Please follow the use and storage methods below.

1. Choose a storage location with good ventilation and no direct sunlight. In a dry powder state, it gradually changes in quality after one year in winter. In summer, the change is faster, so please use it promptly.

2. In an aqueous solution state, deterioration and putrefaction occur faster than in a dry state, so use it within one week.

3. When using, do not replenish by adding more. Use up the old solution before using new Bioflocculant.

4. Dispose of Bioflocculant whose flocculation capacity has decreased. In that case, because Bioflocculant is readily biodegradable, there is no problem with disposing of it in sewer systems or Johkasou systems.

*Caution
If used or stored in hot and humid locations, flocculation performance will decrease earlier than the above usage period. Please use caution.

When Returning Flocculated Sludge to Farmland
Because Bioflocculant contains no harmful substances, harmful metals, or carcinogenic substances, sludge flocculated using Bioflocculant can be safely returned to farmland as a soil conditioner or special fertilizer by composting it.

*Caution
- Bioflocculant itself contains no harmful substances, harmful metals, or carcinogenic substances. However, please note that it cannot separate, remove, or detoxify those substances from the target sludge itself.
- Depending on the composting state, such as immature compost or medium-mature compost, it may adversely affect plants. Before use, conduct germination tests, seedling growth tests, or similar checks on the composted material to confirm that it has no effect on plants.
- Please note that the timing and amount of compost application differ depending on the plant.
