“…5). This variation may be explained by the type of substrate and biofilm employed in this investigation [25]. The temperature was 29.2 ± 0.8°C on average, with variation from the input to the output of the reactor with 30.5 to 28.1°C, respectively (Fig.…”

“…The average removal efficiency was found to be between 80 and 85%. Unlike the operation of other experimental reactors in series [19], [25], the current reactor is setup with a primary and secondary treatment, satisfying the regulations for wastewater discharge to rivers for urban public use (75 mg/L). Furthermore, it complies occasionally to the aquatic life protection limit (30 mg/L) [23].…”

Constructed wetlands (CW) are efficient wastewater treatment technologies with low energy consumption. A constructed wetland with horizontal sub-surface flow was designed at a pilot scale involving Thalia geniculate as vegetation, with a wastewater loading rate of 204±66 L/day, using gravel as inert medium with a porosity and density of n= 56.3 ± 3.5 and 1666.7 ± 119.3 kg/m3, respectively. The reactor allows the biological treatment of 0.85 ± 0.05 and 0.66 ± 0.05 m3 of wastewater, with 4.2 days as a hydraulic retention time, favoring the removal of 85% of the average values of BOD with a k of-0.43 days-1. The pollutant analysis showed a pH value of 7.5 ± 0.1 in the reactor. The temperature (30.44 to 28.32°C), the electrical conductivity (4010 to 2922 μS/cm), the turbidity (144 to 17 UTN) and the bacterial biomass (30000 to 2646 mg/kg) decreased substantially from inlet to oulet across the reactor. The efficiency of the wastewater treatment in the CW is notable, nevertheless, keeping the appropiate hydraulic retention time is important in order to fully comply with the maximum permissible limits of 30 mg/L established in the Mexican environmental legislation (NOM-001-SEMARNAT-1996).

“…Apart from the VFAs content that has its own various application, a lot of studies have been carried out to treat ADE, for example, directly reuse in field as fertilizer [ 225 , 226 ]; cultivate constructed wetland plants and algae, etc. [ 227 , 228 ]; and nutrients recovery [ 229 , 230 ]. Some typical constituents of anaerobic digestion effluent, except for VFAs, are summarized in Table 1 .…”

Sustainable provision of chemicals and materials is undoubtedly a defining factor in guaranteeing economic, environmental, and social stability of future societies. Among the most sought-after chemical building blocks are volatile fatty acids (VFAs). VFAs such as acetic, propionic, and butyric acids have numerous industrial applications supporting from food and pharmaceuticals industries to wastewater treatment. The fact that VFAs can be produced synthetically from petrochemical derivatives and also through biological routes, for example, anaerobic digestion of organic mixed waste highlights their provision flexibility and sustainability. In this regard, this review presents a detailed overview of the applications associated with petrochemically and biologically generated VFAs, individually or in mixture, in industrial and laboratory scale, conventional and novel applications.

The majority of regions in Riau Province are coastal areas and many communities live on land that is dominated by peat. Peat ecosystems have unique characteristics, as they are classified as wetland areas, while also possessing regions of terrestrial land. Poor maintenance of these ecosystems can cause a variety of issues such as forest fires, drought, flooding, biodiversity loss, increasing emissions, climate change, and social community changes. The purpose of this paper is to formulate a model of peatland utilization based on local wisdom and community welfare, in an effort to support the sustainable management of peat ecosystems in Riau Province. The main commodities of the coastal community are agriculture, coconut, rubber, oil palm, sago, coffee, cocoa, areca nut. Therefore, an understanding of the use of peatlands is needed. This is to prevent damage to the peatland ecosystem, maintain biodiversity, store carbon, produce oxygen, and manage water. Policies and strategies for managing the peat ecosystem are carried out through the development of socio-economic and community culture to realize people's welfare based on local wisdom. The management and use of peatlands have contributed to the economy, even as the main source of livelihood for coastal communities. Utilization of peatlands based on local wisdom can maintain a sustainable peat ecosystem.
