Abstract

Wastewaters from a touristic resort were treated by an anaerobic fixed bed reactor and posterior filtration comparing two high rate filters, one packed with sand and the other with natu­ral zeolite. The removal of total and faecal coliforms, Streptococ­cus and Pseudomonas was mo11itored. In the biological treatment, in spite of the variations made in the tlow at the entrance of the re­actor, the reduction of total and faecal coliforms attained values higher than 98 %, slightly better than Streptococcus and Pse11do-111011as. It was found microbiological removal was good and simi­lar for sand and zeolite packed filters. In this case, the pressure losses and the behaviour of the other parameters set the choice of the best ki.nd of granular material.
