Sullage, also known as greywater, is wastewater generated from household activities such as washing dishes, clothes, and bathing. Spray drying has been explored as a method to treat and recover resources from sullage.
Spray drying of sullage involves atomizing the wastewater into small droplets and passing it through a hot air stream, which evaporates the water content and leaves behind dry solids. The resulting powder can be used as a fertilizer or soil conditioner, as it contains nutrients such as nitrogen, phosphorus, and potassium.
Spray drying of sullage has several benefits, including reducing the volume of wastewater for disposal, recovering valuable resources, and reducing the environmental impact of wastewater discharge. However, the effectiveness of spray drying as a treatment method for sullage depends on the composition of the wastewater and the optimization of process parameters such as inlet temperature, feed rate, and air flow rate.
