  • Process for dewatering organic waste product
    Patent number: 4081366
    Abstract: A process for the chemical treatment of organic waste materials contaminated with a pathogenic microorganism, such as raw sewage, sewage sludge and other organic waste products, and to the treated organic waste material so obtained, which process comprises: prereacting the organic waste material with a water-soluble methylol compound subject to condensation, such as a methylolurea compound, under alkaline pH conditions; and, thereafter, condensing the methylol compound by establishing an acid pH condition to form a solid waste product comprising a condensation polymer containing methylene bridges and a sterile solid waste material.

  • Apparatus for treating sewage sludge
    Patent number: 4057392
    Abstract: An apparatus for and a process of treating sludge filter cake and the granular product thereof which comprises reducing the particle size and moisture content of the sludge cake, sterilizing the sludge cake by contacting the sludge cake with an N-methylol-urea solution, reacting the N-methylol-urea solution with the sludge cake at a pH of 3 to 5 while agitating the sludge particles to provide a granular-reaction product, and drying the product to provide a granular, high-nitrogen, odorless fertilizer or animal feed supplement product.
