This research thesis has been carried out at the WWTP San Pedro de Ancon in the treatment of its excess sludge, coming from the activated sludge treatment purge, by means of vermiculture, using the Californian red worm Eisenia foetida as digester and stabilizer. The objective of this thesis is to determine the removal efficiency of the residual sludge by measuring the reduction of parameters of volatile solids, fecal coliforms, salmonella spp and helminth eggs; after 22 weeks of monitoring; the first seven weeks corresponded to a first conditioning stage and the remaining weeks to a second stage of treatment, it is concluded that vermiculture with Eisenia foetida is an efficient treatment in the removal of these parameters, reaching reductions of 9.49% in volatile solids, 97.82% in fecal coliforms, 98.64% in salmonella spp and 96.12% in helminth eggs. Vermiculture is a viable option if the sludge meets the characteristics of worm development. The possible applications are reported according to the category according to Peruvian regulations in the reuse of biosolids. Finally, an application of the humus produced in the transformation of sewage sludge is shown, as a soil improver, in the green areas of the Parque del Recuerdo cemetery located in front of the WWTP in Ancon.
