I am selling the remaining amount because I no longer need it due to moving. I will ship it after taking it out of the box via Yu-Packet Post. Please purchase only if you understand that this is a product inspected by an amateur and stored at home. How about trying it out? Bio-Seeder is effective for restoring and maintaining the function of household septic tanks and various septic tanks. It can also be used for early seeding of newly installed septic tanks. ● Aerobic and anaerobic microbial groups rapidly decompose organic matter in wastewater and become the dominant species, enabling the biological treatment function of the septic tank in a short period of time. ● It is also effective for restoring the function of septic tanks with deteriorated treatment functions. ● It also removes and prevents odors from septic tanks. ● Since it does not contain high-molecular-weight flocculation components, it can also be used in membrane separation type septic tanks. ● It exhibits a strong deodorizing effect through the immediate effect of deodorizing components and the sustained effect of microorganisms. 【How to use】 ・ Seeding of new septic tanks: After filling with water and starting the blower, add 12 packets to the anaerobic filtration tank. ・ Seeding of membrane separation type septic tanks: 40% to 50% of the amount of this agent added will be quickly converted to MLSS. Calculate the dosage of this agent from the required MLSS and add it to the anaerobic filter bed tank. ・ Seeding after regular cleaning: Add 8 packets to the anaerobic filtration tank. ・ Restoration of treatment function: Add 8 packets to the anaerobic filtration tank. ・ Deodorization of odors: Flush 2-3 packets from the toilet.
