“…Over the last two to three years, interesting investigations on the treatment of hospital effluent have been carried out worldwide: consolidated and modified/enhanced technologies as well as new solutions have been tested on the effluent of specific wards, the whole healthcare structure, nursing homes specialised in psychiatric diseases ( 22 ), ( 23 ) or service units such as laundry ( 24 ). They have not only taken place in countries where studies or investigations on hospital effluent have also been carried out, but also in new ones, such as Ethiopia ( 25 ), Columbia ( 5 ), India ( 26 ), Iran ( 27 ), ( 28 ), Costa Rica ( 29 ) and Thailand ( 21 ).…”

Recently, investigations of hospital effluent management and treatment have not only interested research groups with acquired experience in the field but have also attracted the interest of new groups over the world. The most recent literature provides new insights into the occurrence of pharmaceuticals and other contaminants of emerging concern, pathogens, viruses, antibiotic resistant bacteria and genes in hospital effluent in various new developing and developed countries. It also provides information on the effective removal of key compounds (mainly antibiotics, analgesics, beta-blockers and chemotherapy drugs) by means of enhanced biological treatments and advanced oxidation processes. The current debate among the scientific community is mainly about the proper treatment to reduce the spread of antibiotic resistant bacteria and genes, and about the feasibility (from a technical and economic point of view) of treatment trains tested at lab and pilot scale.

“…O Hospital Santa Cruz (HSC) encontra-se no centro da cidade, sendo o principal centro de saúde do Vale do Rio Pardo, RS, com cerca de 23 mil metros quadrados de área construída, e com capacidade de atendimento para 232 leitos. Cerca de 150 m³ de águas residuais são gerados diariamente pelos diferentes setores do hospital, dos quais aproximadamente 50 m³ são produzidos pelas máquinas de lavar roupas (LUTTERBECK et al, 2020).…”

Atividades humanas, como a descarga de qualquer tipo de efluente em sistemas lóticos e lênticos, geralmente sem nenhum tipo de tratamento, estão atualmente se tornando uma das principais preocupações ambientais. Por exemplo, efluentes de lavanderia hospitalar são caracterizados como tendo alto impacto ambiental entre os setores das unidades de saúde. Dessa forma, sistemas integrados de tratamento de efluentes têm sido propostos para melhorar sua eficiência. Neste contexto, esta pesquisa teve como objetivo avaliar a eficiência de um sistema de tratamento multifuncional de baixo custo, integrando o uso de uma célula de combustível microbiana (CCM) com Wetland Construído de Fluxo Vertical (WCFV) para tratamento de águas residuárias da lavanderia do Hospital Santa Cruz, Município de Santa Cruz do Sul, RS, Brasil, utilizando ensaios ecotoxicológicos. Os resultados indicaram que P1, ponto de coleta correspondente ao efluente bruto, apresentou uma toxicidade aguda média de CE(I)50 48h% = 29,3 ± 15,5% (Coeficiente de Variação, CV = 52,8%), sendo classificado como altamente tóxico. Já P2, ponto de coleta correspondente ao efluente tratado, apresentou uma toxicidade aguda média de CE(I)50 48h% = 100,0 ± 0,0 %, sendo classificado como não tóxico. Concluímos, desta forma, que o sistema de tratamento multifuncional de baixo custo para remediação de efluentes de lavanderia hospitalar, fui altamente eficiente, uma vez que houve a completa detoxificação do mesmo, representando uma alternativa promissora para a remoção de toxicidade de efluentes hospitalares.

Surfactants are substances that when in aquatic environments, can cause negative impacts. Hospital effluents carry numerous chemicals daily, including surfactants, used in sanitization and disinfection procedures. These chemicals are found in different concentrations in the effluents and reach water bodies due to a lack of proper removal in the wastewater treatment plants. The present study investigated data about effluents monitoring from healthcare facilities located in the city of Belo Horizonte, Brazil, focusing on anionic surfactants. The results showed, in 2018, a total of 72 establishments monitoring this parameter, resulting in a median concentration of 1 mg⋅L-1 of anionic surfactants in the period. Cationic surfactants still do not have specific legislation in the studied country that dictates a limit for discharge into sewage, however, these compounds are used in the formulation of routine hospital products.
