Abstract: A wastewater treatment system is disclosed which can be used to treat high-strength septage, sewage and industrial wastewater. The wastewater treatment system consists of three major components. In the first component, solids are separated from the liquid component of the wastewater being treated. The separated solid portion is removed to a composting component wherein it is turned into a commercially useful compost material. The liquid component is subjected to a two part treatment wherein the first part of the treatment is carried out in a sequencing batch reactor and the second part is carried out in at least one reed bed. In an alternative embodiment of the present invention, the various components of the wastewater treatment system are in modular form.

Abstract: A tool for forming a soft contact lens having an optical zone formed with a center spherical surface and surrounding aspheric surfaces is disclosed. The tool includes a lens holder having a perfectly centered rearwardly extending cylindrical portion received in a collet of a lens cutting lathe and a transverse front end wall defining a front end opening receiving the lens blank body projecting forwardly through the opening. The lens blank is formed with a mounting flange seated against a rear facing step in the transverse end wall. The lens body is retained in the holder with an insert threadedly received in the holder. A set screw received in the insert applies pressure to the lens blank rear surface to deform the front concave surface which has been previously cut and polished to a spherical surface.
