River purification using biocodes

River purification using biocodes

Using the high-concentration wastewater contact material "BioCode" for river purification.

Currently, the pollution in rivers and coastal areas is caused by domestic wastewater, which accounts for 50-70%. In particular, the concentration of pollutants in domestic drainage channels has progressed to levels where fish cannot survive. This is attributed to the increased pollution load due to population concentration and the reduced self-purification capacity of rivers caused by concrete lining. However, by installing bio-codes in concrete-lined drainage channels, a large number of microorganisms can be fixed, which enhances the self-purification capacity of rivers.

Composite Microbial Preparation: Soil Remediation of Oil Contaminated Soil in Okinawa

Composite Microbial Preparation: Soil Remediation of Oil Contaminated Soil in Okinawa

Application of bioremediation for oil-contaminated soil purification in Okinawa.

In recent years, in Okinawa, soil contamination due to oil and other substances has become apparent alongside the return of U.S. military bases, leading to a serious problem. In Okinawa, the main method for addressing oil contamination is treatment through lime mixing; however, this raises concerns as it alters the properties of the soil. There is growing interest in the effectiveness of bioremediation and its applicability. In response, our company conducted a treatability test (biotreatment suitability test) using Okinawan soil. 【Target Soils】 ■ High-concentration oil-contaminated soil (Kunigami Marge) ■ Medium-concentration oil-contaminated soil (Jagaru) *For more details, please feel free to contact us.

Composite microbial preparation for the remediation of contamination by volatile organic chlorinated compounds.

Composite microbial preparation for the remediation of contamination by volatile organic chlorinated compounds.

Application of our composite microbial agent for the purification of contamination caused by volatile organic chlorinated compounds.

At Bio Rangers, we use a complex microbial formulation (microbial consortium) to address a wide variety of pollutants. Volatile organic chlorinated compounds (VOCs) are considered difficult to dechlorinate to ethylene using anaerobic dechlorinating microorganisms. Our complex microbial formulation "Oppenheimer TCE Formula" has been shown through previous experimental results to be more similar to oxidation reactions under (micro)aerobic conditions, unlike reactions under anaerobic conditions. [Test Cases] ■ Trichloroethylene simulated contaminated water decomposition test ■ Demonstration test of trichloroethylene contaminated groundwater in a certain location in N Prefecture *For more details, please feel free to contact us.
