“…The physical process that occurs in the SSF is the filtration process which includes the transport and attachment of pollutant particles to the filtering media. Sedimentation and adsorption processes also affect the effectiveness of the removal (Dampang et al, 2022;Kurniawan et al, 2022). SSF is very suitable for water treatment in developing countries, due to its uncomplicated design, passive mechanism, operation, and relatively easy maintenance (Byrne, 2010).…”

This study aimed to determine the performance of modified slow sand filter (SSF) media with blood clam shells (Anadara granosa) and activated carbon to remove turbidity, TSS, TDS, and FOG on the food court wastewater. The concentration of water pollutant parameters processed by SSF was determined based on Indonesia water quality standards, as well as knowing the optimum operational parameters of intermittent slow sand filter with Response Surface Methodology (RSM). The research data was processed using the Optimal type (custom) design which consisted of independent factors including the type of filter media, the addition of bacteria to the grease trap pre-treatment unit, and running time, as well as the research response in the form of the effectiveness of removing turbidity, TSS, TDS, and FOG. The reactor was operated intermittently (48 hours) for a maximum of 22 days and the concentration of pollutant parameters was calculated using the Standard Methods. The results of the Analysis of Variance (ANOVA, p<0.05) in the 2FI model of the study showed that there was a significant effect of all independent factors on the effectiveness of removing all water pollutant parameters. The most optimal operational parameters were achieved with the type of activated carbon media, the addition of Bacillus sp. in the grease trap pre-treatment unit in the amount of as much as 1%, and the detention time of 4 days, with the effectiveness of removing turbidity reaching 39.53%; TSS 45.25%; TDS 19.30%; FOG 61.35%.

“…The long-distance transfer of ballast water and sediment enables aquatic organisms to spread across natural biogeographic barriers, providing opportunities and possibilities for species invasion [6][7][8]. Thousands of species flow with ballast water around the world every day, among which more than 100 alien species have been identified by scientists as suspected alien species [9,10]. After successful colonization in the new environment, alien species will multiply in large numbers and become dominant species, which may lead to repeated invasion disasters periodically.…”

Alien invasive algae along with ship ballast water have posed a serious threat to China's marine ecological security. A clear understanding of the geographical distribution of invasive species and their response to climate change can provide a scientific basis for their prevention and control. In this study, combined with environmental variables and distribution data, MaxEnt was used to predict the potential geographical distribution and change trend of Alexandrium in the four major sea areas of China currently, 2040s (2040-2050) and 2090s (2090-2100), reveal the dominant environmental factors affecting the geographical distribution, analyze the migration trends of centroids the highly suitable area, and clarify the key control sea areas. The results showed that: 1) The AUC values of all models were significantly higher than random models, and the Kappa statistics of all models were higher than "general", demonstrated that the prediction results were available.2) The most important environmental variable affecting the geographical distribution of Alexandrium was the Temperature. Range (bio24), and its suitable range was 23.43-31.52ºC. 2) At present, in the corresponding sea areas of Nantong,

“…As population grows rapidly, clean water consumption also increases, which results in the surge of the amount of wastewater that can pollute the environment (Purwanti et al, 2018b). Wastewater comes from domestic activities, industries, and other public places (Ighalo et al, 2022;Igwegbe et al, 2022;Kurniawan et al, 2022c). It contains the materials that can endanger the life of humans and other living beings and disturbs environmental sustainability (Al-Ajalin et al, 2020).…”

This research aimed to discover the macroscopic, microscopic, and physiological characteristics and the genus of heterotrophic bacteria found in the schmutzdecke or biofilm layer in slow sand filters. The isolation of heterotrophic bacteria in the schmutzdecke applied the pour plate and quadrant streak method, while the characterization used macroscopic, microscopic, and physiological tests. Samples were taken from the schmutzdecke on top of the filter layer, and they were diluted 3, 4, and 5 times, then grown in Nutrient Agar media in order to isolate heterotrophic bacteria. The results of the research were analyzed using the identification manual books titled Bergey's Manual of Determinative Bacteriology, 9 th edition and Manual for The Identification of Medical Bacteria, 3 rd edition. These manuals show the names of the genus of bacteria in the schmutzdecke layer. On the basis of the identification results from macroscopic, microscopic, and physiological tests, there were 4 dominant genera out of 18 living isolates obtained from the schmutzdecke layer, namely Kurthia gibsonii, Bacillus badius, Bacillus firmus, and Bacillus lentus. The similarity percentage of these 4 isolates was 83%, 81%, 85%, and 77% respectively.
