【Environmental Service】 Wastewater treatment O & M and Dioxin Analysis
Facility O&M and Analysis of water quality withour solid techniques- HIYOSHI CORPORATION -The Only One Unique and Quick Analysis
method for Dioxin Analysis

Features・ 60 years of experience in Japan, more than 80 business licenses,
and a total of 1900 personnel qualifications
・.One-stop Environmental Service: O&M, water testing, water treatment,chemical supply, installation repair work, solid waste treatment.

Overview“Everything starts from measurement” based on this principle, we
provide comprehensive solution to Environmental related issues.

Hiyoshi Corporation
908 Kitanosho, Omihachiman,Shiga, Japan 523-8555

It is approved as an official method in Japan, USA, EU and Taiwan
・Comparison with Instrumental Analysis:✓High Correlation✓ Cost is about ½✓ Turnaround is less than 1/4
・In Japan about 60,000 samples were analyzed
・Can be used for an official measurement screening , or internal testing purpose.
CALUX BIOASSAY (HighLux) is a reporter-gene bioassay that uses amouse recombinant cell line which can measure Dioxins in various matrices
such as Environment (ash, exhaust gas, soil, etc.) as well as biological andfood matrices.

Performance・Specifications of Technology・Product
Facility O&M and Analysis of water quality with
our solid techniques
With one window, we can solve any problems related to facility
management, so we can reduce cost, labor, time and so on.
Since each expert is present, it is possible to comprehensively judge
the problem and deal with it.
Even when accidents or troubles occurrs, the relevant department
can be contacted quickly for appropriate response.

The Only One Unique and Quick Analysis
method for Dioxin Analysis【Accuracy】

Since it highly sensitive as 0.19pgTEQ/well,it require less sample amount【Analysis Cost】No need of expensive instrument and so theanalysis can be done at low cost
【Analysis time】Using highly sensitive cells shortens the process andthus reduces the time for analysis【Simple Process & Operation】Does not reed complicated instruments
and so it is easy to set up.
【High performance】High Correlation with HRGC/HRMSCALUX (HighLux) vs. HRGC/HRMS（Conventional Method）

Usage Example・Actual Performance
In Japan, there are many achievements, from public sectors to theprivate sectors, such as water treatment, sewage treatment facilities,
waste disposal facilities, effluent wastewater treatment facilities andseptic tanks.
Furthermore, from the experience of wastewater treatment facilities
O&M in remote areas, we established a remote monitoring system
making it possible to maintain facilities not only in Japan but alsooverseas.

Japan (JIS K0463, MoE): Emission gas, ashes, and cinders.
USA (EPA Method 4435): Solid Waste
EU(Commission Directive 2002/69/EC): Food and Feed
Taiwan (NIEA S901.60B5): Soil
Because of 1) Low cost 2) Faster turnaround 3) Less sample amount,
it is being utilized in various field.
【Screening method】- Kanagawa Prefecture (Ashinoko Lake-Environmental survey carried out
to check the actual quality of sediment)- Nagahama city, Shiga prefecture (Survey of dioxins in soil)- World Bank (Biological Monitoring of POPs in SE Asia)【Self inspection / Product Development / Research】
There are various ways to use the method; Monitoring of waste incinerator,
product development such as dioxin inhibitor investigation of pollution ofdioxin in living organisms (blood, biological samples etc.)
