Cycleau

Long description

Cycleau is a compact greywater treatment system designed to retrofit below sinks to capture and treat greywater for potable water reuse applications. The hardware unit, which is sized at approximately 24 inches by 36 inches, connects to the drain pipe and water supply lines which remain exposed below most sinks to redirect incoming municipal water supplies through a point-of-use treatment system that removes public water contaminants, while also collecting greywater for immediate treatment and purification to potable standards. To provide clean water, Cycleau serves as a point-of-use treatment system where water can be filtered and purified immediately before it’s consumed. To reduce sewage pollution, it directly reduces the size of a building’s wastewater footprint by capturing a fraction of greywater for on-site reuse applications, while also treating all other wastewater before it leaves the building to prevent household contaminants from entering the local aquatic ecosystem. 

Cycleau operates by way of a comprehensive, five-stage wastewater treatment system. Greywater first passes through a coagulation chamber, where a chemical coagulant such as aluminum sulphate is added to water supplies to attract and coagulate suspended particles. Physical particles are then filtered through a bed media chamber and three stages of membrane filtration. Water is then disinfected by UV irradiation and purified by advanced oxidation. These stages are adapted from the processes used in municipal wastewater treatment plants, though through their modular design they become capable of decentralizing our urban water systems to advance circularity in water consumption patterns.
