“…The results showed that modification of some current slaughter methods, the installation of filters at slaughterhouse drains, and avoiding application of slaughterhouse wastewater treatment sludge-derived fertilizer to grazing and forage producing land could decrease the likelihood of specified risk material contamination. (Fijan et al, 2006). The results demonstrated the presence of rotaviral RNA in wastewater after the washing process, indicating the hospital laundry disinfection procedure was not sufficient to prevent the transmission of rotaviruses.…”

“…Karanis et al (2006) Rotaviruses are the leading cause of diarrhea in humans. A study on the occurrence of rotaviral RNA in hospital laundry wastewaters was conducted using real time-PCR combined with a second round PCR followed by ultra-filtration and RNA isolation (Fijan et al, 2006). The results demonstrated the presence of rotaviral RNA in wastewater after the washing process, indicating the hospital laundry disinfection procedure was not sufficient to prevent the transmission of rotaviruses.…”

“…Several studies have reported the high incidence of these coliforms in wastewater from hospital laundries. 37,66,75 In this sense, the scientific community reports several cases of infection in hospital laundries: 65 rotaviruses, Clostridium difficile, 49,51,61 influenza virus (H1N1), 73 Streptococcus spp., 182 Enterococcus spp., 70,71 Acinetobacter spp., 69 Staphylococcus spp., 68,183 Pseudomonas, 67 Bacillus spp. 54 and hepatitis A virus.…”

Water is a fundamental substance for the existence of life on earth. However, globally there is a freshwater crisis. Hospitals generate exorbitant volumes of effluents (5 to 15 times more toxic than urban ones). Hospital laundry is known for demanding the highest volumes of water, generating a proportional amount of complex effluents with high toxicity and recalcitrance. Adequate treatment for hospital wastewater is always an essential solution. Among all treatment methods, coagulation/flocculation emerges as one of the best alternatives. However, the use of traditional compounds such as aluminium sulfate has caused secondary pollution; its residues are harmful to public and environmental health. In this sense, the present study used natural compounds that do not cause adverse effects, such as chitosan/hydroxyapatite, to clarify the laundry effluents of the largest hospital from the Tocantins. The results showed that the hydroxyapatite associated with chitosan, at pH 6 and dosage of 50 mg/L, reduced the turbidity and apparent colour of these wastewaters by up to 67 and 55%, respectively. With lower performance and higher dosage (60 mg/L), the chitosan gel used (pH 6) promoted a maximum reduction of 35% of the apparent colour and 40% of turbidity.
