Activities
Products[Kitchen Wastewater Treatment facility]
It is mandated to meet the quality standard to discharge wastewater to sewers from buildings, commercial
facilities, complex malls, meal service centres, etc., in accordance with the Sewerage Service Act ofJapan and the relevant municipal ordinance.
Wastewater from kitchen often contains a lot of oils, fats and organic residues, which mostly requires"pressurized floating treatment method" to physically and chemically removes oil and fats, and "activatedsludge treatment method " to remove and reduce organic matter "or equivalent processing method. These
requirements entails customers additional financial cost for managing odour generated from removed oiland excess sludge; and disposal of sludge. DK AQUA Corporation has developed "BCS (Bio catalyticoxidation method)" which realizes efficient water treatment performance applying our proprietary oiland-fat decomposing bio-bacteria eventually to reduce such financial cost.
[Medium water equipment]
The owners of building and development planners with a designated size/scale are required to observe
the conditions set forth in the relevant ordinance and the Guideline on Efficient Use of Water. Increasing
number of buildings and projects adopts recycling of water to realize the society where water resource isrecycled.
DK AQUA Corporation proposes diverse and appropriate facilities according to the nature and scale ofraw water to enhance recycling of water under the budget.
[Wastewater treatment facility of Food factory]
Wastewater discharged to public waterbodies from factories such as food industries as designated in therelevant law are mandated to meet the national effluent standards. The standards set forth 1) hazardous
parameters such as dioxins and 2) human life-environmental parameters such as COD, Total-N, Total P.
Prefectural government are also authorized to enforce a set of more stringent standards.
DK AQUA Corporation offers best wastewater treatment system considering locations, scale, products,and laws and regulations to meet the budget.
In addition, DK AQUA Corporation provides service to assist the client in preparing and submitting
application forms for wastewater management, designing and constructing, operating wastewater
treatment facilities, monitoring and recording wastewater quality, attending on-site inspection andpreparing other types of reports mandated under the laws.

Daiichikankyo-Aqua Corporation"BCS (Bio catalytic oxidation method)"
It is a system to decompose oils and pollutants by “bio”.
1.«Tank capacity» compact design (2/3rd or less), which makes the installation cost lower
2. The treatment process does not emit noticeable odour. Therefore, it does not require
installation of large scale deodorizing equipment.
3. It does not adopt activated sludge, which would therefore not require any disposal ofexcess sludge. The cost can be minimized accordingly.
4. Operation and maintenance cost may be halved due to the simple treatment process.
5. It is also possible to install an additional facility to enable recycle of treated water after
the BCS treatment process.
We propose an appropriate set of system to minimize the installation and O/M cost byassessing the nature & concentration of wastewater, availability of pre-treatment
equipment such as grease trap, etc. and dimensions of the facilities.
