Water is absolutely necessary for the survival of all living things and one of the most essential sources of economic activities as well.
But currently the world is facing a serious water problem due to population growth and economic development.
One of water problems is water pollution. In areas where sewerage and Johkasou (STP) are not widely covered, human-waste and miscellaneous wastewater is discharged directly into rivers and the ocean. If this goes on, water will continue to be contaminated.
“Johkasou(STP)”can contribute to the solution of these problems.
Johkasou is a facility that treat human-waste (water from toilets) and miscellaneous wastewater (water from kitchens, bathrooms and laundry machines, etc) and discharges them into reivers other than public sewers.
It decomposes and filters various substances, and treats dirty water properly and returns it to nature.
We at Daiki Axis manufacture wastewater treatment products at our Johkasou-STP manufacturing plant equipped with the latest equipment.
Separation BoxSeparate solids in wastewater by gravity and prevent the agitation of the excess sludge in Sedimentation & Separation Chamber by influent.
Separation & Sedimentation ChamberSeparate solid debris or impurities from water in influent and circulated water and store these sediments in the chamber.Accumulated sludge should be desludged from the tank periodically at least once in 6 – 12 month.
Anaerobic ChamberIt is filled with filter materials, which separate solids and keep anaerobic microorganisms to decompose organic mater.
Moving Bed ChamberIt is filled with mesh cylindrical media, which retain aerobic microorganisms to decompose and remove organic matter from wastewater.
Sedimentation ChamberIn order to obtain clear treated water, separate the excess sludge (suspended solids,SS) by gravity. The settled sludge is constantly returned to the sedimentation & separation chamber by the airlift pump.
Disinfection ChamberDisinfect the treated water to discharge to the river or other water bodies.
SAVE ENERGY COST
Compared with conventional sewage treatment plant, Johkasou requires only 50% less energy.
NO NEED RESIDENT OPERATOR
Unlike conventional wastewater treatment systems, Johkasou do not require an operator to constantly monitor them. Labor costs associated with Johkasou management can also be reduced.
GOVERNMENT CERTIFICATION PRODUCT
Our product's ability and structure have been certified by the Japanese Government. Overseas factory has facilities fitted with the same equipment as those in Japan, therefore we can provide Japanese quality products.
ADVANCED TREATMENT PERFORMANCE
Johkasou has the circulation system and makes it possible to repeat nitrification and denitrification process. This provides the advanced treatment for the wastewater.
The key point of the process is to repeat "Nitrification" and "De-nitrification" continuously in succession.
NO NEED EQUALIZATION TANK
Johkasou has a recirculation system for wastewater treatment in a single tank, designed to generate a cycle of nitrification and denitrification, treating the wastewater over and over again in the tank to obtain clear treated water.
AGAINST PEAK INFLOW RATE
Product is already designed by taking account for the peak flow rate. The peak flow rate upto 2.5 times higher than the average flow rate can be treated without any additional equipment.
EASY TO INSTALL
Just connect inlet/outlet pipes and electric cables!
The structure of the Johkasou is simple, and its equipment is user-friendly. Therefore, it is easy for operation & maintenance.
