Abstract: An apparatus for separating fats, oils, and greases (FOGs) and miscible organics that are present in the wastewater from businesses, institutions, and industries such as restaurants, hospitals, and food processing plants. The apparatus can be installed in situ or can be mobile. The apparatus provides for wastewater to flow through a network of fluid channels, for example a distribution pipe, on to an absorption/filtration media within a substantially watertight container. The wastewater percolates through the absorption/filtration media leaving FOGs behind inside the container, which have been absorbed by the organic absorption/filtration media. Fluid, free of the organic waste, flows through a fluid removal pipe at the bottom of the container, thereby exiting the container. The organic absorption/filtration media saturated with organic waste can then be treated in an environmentally sensitive manner by composting, land application, incineration or land filling at a remote site or composted on site.
