“…For developing countries, the expense of treatment is a concern. Previous research also demonstrated that shredded waste PET bottles as biofilm media provided a 70-90% COD removal, which meets Bhutan's discharge regulations [10,12]. Therefore, one of the best ways for the local government to reduce the environmental impacts is to waste PET plastic bottles.…”

Small-scale businesses often dominate the tofu sector in Makassar City, preventing any prior wastewater management. While tofu is typically produced on a household scale, the wastewater treatment process is limited due to the need for suitable technology and high prices. Therefore, it is necessary to conduct this research to obtain tofu wastewater results that meet environmental discharge standards and develop a straightforward and affordable waste treatment concept. A laboratory scale with an experimental method is used in this study, where the test parameters used were BOD, COD, and TSS using two types of biofilter media, namely mineral water bottle media made of PET plastic and plastic straw media made of PP plastic with variations in observation time of 24 hours for six days. The results presented that the efficiency of the average removal in plastic-media reactors with mineral water bottles reduced BOD by 88.30%, COD by 88.97%, and TSS by 79.13%. The straw-based plastic reactor reduced BOD by 86.74%, COD by 85.41%, and TSS by 67.03%. The effectiveness value obtained shows that biofilter media made from plastic mineral bottles (PET) produces better effectiveness in removing BOD, COD, and TSS than biofilter media made from plastic straws (PP).

“…In terms of economy, the cost for certain technology is closely linked with treatment purposes (discharging, reuse for irrigation or toilet flushing) and user number, so it might not be suitable to make a direct comparison (Dorji et al, 2022). Conventional biological and ecological processes are cheap options in terms of both capital expenditure and operating expenditure, making them suitable for water treatment and discharging in developing countries, especially in temperate regions (Boyjoo et al, 2013).…”

Blackwater (BW), consisting of feces, urine, flushing water and toilet paper, makes up an important portion of domestic wastewater. The improper disposal of BW may lead to environmental pollution and disease transmission, threatening the sustainable development of the world. Rich in nutrients and organic matter, BW could be treated for resource recovery and reuse through various approaches. Aimed at providing guidance for the future development of BW treatment and resource recovery, this paper presented a literature review of BWs produced in different countries and types of toilets, including their physiochemical characteristics, and current treatment and resource recovery strategies. The degradation and utilization of carbon (C), nitrogen (N) and phosphorus (P) within BW are underlined. The performance of different systems was classified and summarized. Among all the treating systems, biological and ecological systems have been long and widely applied for BW treatment, showing their universality and operability in nutrients and energy recovery, but they are either slow or ineffective in removal of some refractory pollutants. Novel processes, especially advanced oxidation processes (AOPs), are becoming increasingly extensively studied in BW treatment because of their high efficiency, especially for the removal of micropollutants and pathogens. This review could serve as an instructive guidance for the design and optimization of BW treatment technologies, aiming to help in the fulfilment of sustainable human excreta management.

“…The effective removal and treatment of wastewater are essential for environmental protection and human health [10]. Numerous theoretical and practical approaches have been developed to address this challenge, with an emphasis on different shredded materials and their role in these methods [11][12][13][14][15].…”

The primary objective of this research was to assess the efficacy of a novel solution under conditions closely resembling those of real-world scenarios. Biological beds, or filters, hold significant potential for widespread implementation in individual households, particularly in areas with dispersed housing. The system’s aim was to improve the quality of wastewater treated in on-site domestic biological treatment plants. A pivotal aspect of the project involved developing a prototype research installation for conducting comprehensive testing. Our installation system consisted of several components designed to create a laboratory-scale model for domestic wastewater treatment. The model comprised four biological reactors filled with ABS material and secured by a PUR frame. Additionally, the tested model included a controller for wastewater dosing control, a septic tank as a reservoir, and four tanks for collecting purified wastewater. Through regression analysis using the Generalized Linear Model (GLM), a correlation between CODCr and TSS was revealed. This study presents the research findings concerning the development of a prototype installation that incorporates an advanced reactor or filter. The data derived from this research have the potential to contribute to the creation of products that enhance the performance and efficiency of household wastewater treatment systems.
