Washing machines in the context of "Ultrasonic cleaning"

Greywater (or grey water, sullage, also spelled gray water in the United States) refers to domestic wastewater generated in households or office buildings from streams without fecal contamination, i.e., all streams except for the wastewater from toilets. Sources of greywater include sinks, showers, baths, washing machines or dishwashers. As greywater contains fewer pathogens than blackwater, it is generally safer to handle and easier to treat and reuse onsite for toilet flushing, landscape or crop irrigation, and other non-potable uses. Greywater may still have some pathogen content from laundering soiled clothing or cleaning the anal area in the shower or bath.

The application of greywater reuse in urban water systems provides substantial benefits for both the water supply subsystem, by reducing the demand for fresh clean water, and the wastewater subsystems by reducing the amount of conveyed and treated wastewater. Treated greywater has many uses, such as toilet flushing or irrigation.

Akai (Japanese: 赤井, pronounced [a̠ka̠i]) was a Japanese electronics manufacturer, established as Akai Electric Company Ltd in Tokyo in 1929. It was best known outside Japan for its tape recorders during the 1960s and 1970s. The company became bankrupt in 2000 and since then third-party products have been marketed under the Akai brand name, which has since been owned by Grande Holdings of Hong Kong.

In its earlier history, Akai had made many innovations in the development of magnetic tape-based audio technology. Around 1980, the music division Akai Professional was founded, offering production and stage equipment for modern music. After the controversial collapse of the business in 2000, the Akai brand came under the ownership of Hong Kong based Grande Holdings. The company now distributes a range of electronic products, including LED TVs, washing machines, clothes dryers, air conditioners, and smartphones. These products are developed through collaborations with other electronics companies with relevant expertise.
