Peng F, Lu Y, Dong X, Wang Y, Li H, Yang Z. Advances and research needs for disinfection byproducts control strategies in swimming pools. JOURNAL OF HAZARDOUS MATERIALS 2023; 454:131533. [PMID: 37146331 DOI: 10.1016/j.jhazmat.2023.131533] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/05/2023] [Revised: 04/16/2023] [Accepted: 04/27/2023] [Indexed: 05/07/2023]
Abstract
The control of disinfection byproducts (DBPs) in swimming pools is of great significance due to the non-negligible toxicity and widespread existence of DBPs. However, the management of DBPs remains challenging as the removal and regulation of DBPs is a multifactorial phenomenon in pools. This study summarized recent studies on the removal and regulation of DBPs, and further proposed some research needs. Specifically, the removal of DBPs was divided into the direct removal of the generated DBPs and the indirect removal by inhibiting DBP formation. Inhibiting DBP formation seems to be the more effective and economically practical strategy, which can be achieved mainly by reducing precursors, improving disinfection technology, and optimizing water quality parameters. Alternative disinfection technologies to chlorine disinfection have attracted increasing attention, while their applicability in pools requires further investigation. The regulation of DBPs was discussed in terms of improving the standards on DBPs and their preccursors. The development of online monitoring technology for DBPs is essential for implementing the standard. Overall, this study makes a significant contribution to the control of DBPs in pool water by updating the latest research advances and providing detailed perspectives.

[PMID: 36869957 PMCID: PMC10121517 DOI: 10.1007/s11356-023-26126-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 09/23/2022] [Accepted: 02/21/2023] [Indexed: 06/18/2023]
Abstract
The aim of the research was to check the possibility of using the rinsing water after rinsing the recreational pool filters, cleaned with the rinse water recovery system, for irrigation of green areas. The system consists of the following stages: flocculation, pre-filtration, and ultrafiltration based on filter tubes. The degree of contamination of the rinse waters before and after the treatment process was assessed by means of physicochemical and microbiological tests, and then compared with the permissible parameter values for wastewater discharged into the ground or water. Thanks to the use of flocculation and appropriate ultrafiltration, the high level of total suspended solids and total organic carbon was reduced, which allows for safe discharge of purified water into the environment. Circular economy, wash water, zero waste technologies, water footprint, water recycling.
