Case Study of Disinfection Testing for Legionella Bacteria: Water Purification Device 'Mecasera Device'
Mechacera device
Under the presence of residual chlorine at 0.1 to 0.2 ppm, the mecacera ball acts ⇒ the number of Legionella bacteria is zero after 24 hours! *Demo units available for loan.
The term "Legionella" refers to bacteria that inhabit rivers, lakes, hot springs, and soil, and can cause Legionnaires' disease upon infection. Approximately 60 species are known to date, among which Legionella pneumophila is considered a representative species that causes Legionella pneumonia. 【Legionella Bacteria Disinfection Test Using Mekacera Water】 ■ Method (1): Effect of Residual Chlorine Concentration on L.p.1 It is said that Legionella bacteria die within 15 minutes at a residual chlorine concentration of 0.4 ppm, so first, we investigated how much the residual chlorine concentration affects Legionella bacteria. ■ Method (2): Effect of Mekacera Water on L.p.1 It was considered that a residual chlorine concentration below 0.2 ppm would have little effect on the number of Legionella bacteria, so tests were conducted within the range of 0.2 ppm or lower. ★ Results ★ As a result, when Mekacera balls were applied in the presence of residual chlorine concentrations between 0.1 ppm and 0.2 ppm, the number of Legionella bacteria gradually decreased, and no viable bacteria were detected after 24 hours! * You can experience the actual effects with the demo unit. * For more details, please refer to the PDF document or feel free to contact us.

Company information
The main business of SGM Corporation, the "Mecasera System," was developed in 1983 through joint research with Tohoku University. The core technology of this system is the superoxide ion generation method, which is aimed at water quality purification treatment of waste oil and other substances, as well as deodorization, water quality purification, and sludge reduction of sewage and domestic wastewater in agricultural communities and sewer systems. The water purification quality is remarkably stable and low-cost, requiring no modifications to existing equipment, and it can be used semi-permanently as a reliable and robust product. For over 30 years since its launch, there have been numerous achievements, including local governments (agricultural communities), major companies in Japan, and various foreign countries.
