PFAS Removal Services

Certificate of measurement for PFOS and PFOA: values detected before treatment fell below the quantification limit after treatment

A scientific approach
Restoring water safety

Okinawa Environmental Engineering not only sells PFAS removal equipment, but also performs the removal process on-site.
We accurately calculate the characteristics and concentration of PFAS (fluorinated organic compounds) and the treatment effect of ozone, and then safely and reliably remove them in the most appropriate way for each type of contaminated water.

We purify the water to a level that meets not only domestic but also global environmental standards , restoring the water to its original safety and clarity.
In fact, when spring water in Okinawa Prefecture was treated, the PFOS and PFOA concentrations were significantly reduced from 91 nanograms to less than 1 nanogram.
The analytical results prove its technical capabilities.

Implementation track record

Pond at Wakatake Park, Ginowan City

[Case Report] PFAS Reduction at Wakatake Park, Ginowan City

Wakatake Park Pond Restoration Project — At Wakatake Park in Ginowan City, high concentrations of PFAS had been detected in the pond water, and use of the pond was restricted for a long period.

FAQ

PFAS / PFOS Countermeasures
How much can concentrations be reduced?
It depends on the raw water characteristics and the process configuration. Significant reductions have been confirmed in actual field projects
(evaluated on the basis of analytical results).
What are the guideline values in Japan?
Japan sets a provisional target value for the combined total of several substances. Because implementation varies by municipality,
please consult us about your specific case.
Can you handle projects outside Japan?
Yes. The United States has set strict water quality standards, and regulations are being tightened worldwide.
We propose designs tailored to the target values.
Can ozone alone decompose PFAS?
Complete decomposition is difficult. Ozone works as a pretreatment that reduces the organic load, improving the efficiency and service life of adsorption and membrane processes.
We design optimal systems on this basis.
