The technology removes fatty acids, gums, sulfur and metals from various triglyceride feeds such as used cooking oils and tallows allowing the production of pure triglycerides for the oleochemical and biofuel sector. This aqueous–based process can be operated under batch or continuous conditions and can be tailored to impurity levels within the used triglyceride. The technology can be used to treat previously inaccessible feedstocks and can also be recycled
