Stick-bed Biofix is a special contact media made of polyester monofilament as a frame and absorbent acrylic fiber as a sludge holder. From it’s innovative effects, this Biofix will lead to new applications in wastewater treatment that were never considered possible by biological process.

Stick-bed Biofix has the following good points because of its original structure.
●The surface area is six times larger than Biofringe.
●The retained sludge volume is a maximum
　―10 times greater than Biofringe.
●Delivers good effluent quality because the contact 　probability is high owing to its three-dimensional
　structure that creates turbulent currents.
●Less blockage of water currents occurs because
　the gaps in the textile are wide. Sludge does not
　drop all at once.
●Holds sludge tightly and stable.
●Offers new applications with anaerobic pretreatment.

 

Compared with Biofringe, Biofix has the unique features shown in the table below

	BIO FRINGE	BIO FIX
Surface area	1	6
Hold sludge volume	1	Max. 10
Blockage	◎Never occurs	△Occurs minimally
Contact	High frequency (Velocity) High efficiency	High probability (wide surface area, turbulence currents) High accuracy
Application	Highly effective versatile material	Highly effective function-added material

 

Stick-bed Biofix has developed new applications, as mentioned below, because of its unique characteristics.
●Higher contact probability
　 (From wide surface area + turbulence currents)
　　　　↓
　Biofilter, Recycling, Pretreatment system
　for drinking water.
●Holds higher sludge volume
　(as a result of high sludge retention efficiency and wide surface area)
　　　　↓
　High efficiency BOD removal
●Anaerobic
　(From high sludge retention efficiency and wide surface area)
　　　　↓
　SS, Starch, Dissolve, Refractory organics,
　Organic acid, Nitrogen removal,
　Anaerobic trickling filter
