In the field of environmental science, the technology of SOFT99 Group is also used.
Advanced wastewater treatment equipment (AION's own plant)
-
In order to meet the new wastewater standards of the Ibaraki Prefectural Ordinance (BOD and COD both 10 ppm or less), advanced wastewater treatment equipment was installed.
The wastewater load of BOD, COD, and SS*3 was halved.
*3 SS: Represents the amount of floating material.
The process of this device (flowchart on the rightflowchart below)
AION PVA Microbe Carriers
Sludge dewatering machine "PC separator"
Two environmental technologies are used. 
Microbe Carriers
High affinity with microorganisms, wastewater treatment using PVA sponge having a high porosity of about 90% and continuous pore structure, Immobilized microbe carriers for deodorization treatment.
Because it has excellent abrasion resistance and is not decomposed by microorganisms, it can be used for a long period of time, saving the time and cost of replacement and replenishment.
PC Separator
High-precision, high-performance compact type continuous vacuum solid-liquid separation device using advanced percolation material.
Sludge Recycling
-
The most difficult aspect in wastewater treatment is the treatment of sludge.
AION outsources to compost and recycle all sludge.
The extracted sludge is placed in a container and transported to the processor, where it is composted through a fermentation process.
Applications include soil improvement materials, greening materials, etc.
