HighlightCatfish aquaculture wastewater contains organic matter that exceeds the quality standard of 68.75 mg / L and 72.48 mg / L.Tutut Jawa snail (F. javanica) can reduce organic matter in waste by up to 92%.Susuh Kura snail (S. testudinaria) can reduce organic matter in waste by up to 87%.Catfish aquaculture wastewater treatment with snails only takes 8 hours. Abstract The residual or wastewater from the cultivation process that is discharged directly into common waters can reduce the quality of the waters because it contains a lot of organic material from organism feces and feed residue, so it needs management first. The purpose of this study was to determine the ability of Javanese snails and freshwater gastropods to reduce total organic matter in catfish culture waste. The research method used was the experiment with 2 factor Factorial completely randomized design, namely the measurement time (4, 8, 12, and 16 hours) and the abundance of the Tutut Java snail and freshwater gastropods (100%, 75%, 50%, 25%, and control) with 5 repetitions. Tutut Java snails were taken from the pond at UPR Sumbermina Dau and brought to the laboratory. The results obtained in the treatment with the addition of  Tutut Java snail, the total organic matter content decreased at 75% snail density by 90% (from 68.75 mg / L to 5.31 mg / L) at the 12th hour. The treatment with the addition of Freshwater Gastropods at a density of 25%, the total organic matter content decreased by 87% (from 72.48 to 9.35 mg / L) at the 8th hour. Water quality during the study was in a condition that could tolerate the Tutut Java snails and freshwater gastropods. The conclusion is that the addition of Tutut Java snail and / or freshwater gastropods can reduce the total organic matter content to the water quality standard.

Abstract Biofilters have been recognized as key technology in the mitigation of greenhouse gases (GHG) emitted by landfills. This study aimed to evaluate the methane (an important GHG) oxidation efficiencies of two experimental biofilters at the municipal landfill of Guarapuava (Brazil) under normal conditions (control column), just using landfill cover soil with low organic matter content, and improved, exploiting dried scum from municipal wastewater treatment plant (SWWTP) mixed with the cover soil (enriched column, with a high organic matter content). The influence of parameters such as the methane inlet loading rates (22 and 44 gCH4.m− 2.d− 1), temperatures, methane concentration in the raw biogas, carbon/nitrogen ratio and moisture content of the packing materials on the oxidation of methane was also evaluated during 25 campaigns. The campaigns with the lowest methane loading rates applied to the biofilters showed the best methane oxidation efficiencies (98.4% and 89.5% in the enriched and control columns, respectively) as compared to campaigns with a higher load (92.6% and 82.6% in the enriched and control columns, respectively). In addition to the loading rates, the methane oxidation efficiencies were highly influenced by the organic matter content and C/N ratio of the packing materials evaluated.

Abstract Biological treatment methods are used to remove organic and some inorganic substances from wastewater using the simplest organisms that use these substances for nutrition, breaking them down using cellular processes. The article deals with the aerobic, anaerobic and anoxic stages of biological wastewater treatment. Their differences are explained and the best way to use biological processes is analyzed according to the type of industry/production. At wastewater treatment plants, anaerobic treatment is often used at first to remove a significant part of organic substances from wastewater before sending them for further aerobic treatment. Aerobic treatment is effective for various types of wastewater, especially with lower biochemical oxygen demand (BOD) and chemical oxygen demand (COD). A comparative analysis of wastewater composition from food, oil and gas processing, pharmaceutical and pulp and paper industries was carried out. In the presence of organic compounds, the technology is chosen depending on the total organic matter content or the total COD content, which characterizes the total organic matter in water. A combination of anaerobic and aerobic methods is possible, if a discharge into the sewer system or into water bodies is required. The grounds for the application of biological wastewater treatment of these industries are given.

Dissolved Form

Distribution of total organic matter and its dissolved and suspended forms was investigated in two small estuaries with different morphometric characteristics, as Muchke and Toki Lakes, in late July 2014 at the low tide phase. The time of survey was distinguished by low river discharge and high tides. Content of all forms of organic matter and hydrocarbons was higher in the estuarine waters, as compared with fresh river water, regardless of salinity. The dissolved form prevailed (79.7-98.6 % of the total organic matter content) with concentrations of 5.2-35.7 mg/l. Chlorophyll a dominated (up to 87 %) among phytopigments in both estuaries that corresponded to active development of microalgae. Toki Lake was distinguished by higher productivity and microplankton abundance. On the contrary, allochthonous organic matter was more abundant in Muchke Lake, where interrelation between destructors (heterotrophic bacteria number) and primary producers (Chl a concentration) was observed. Oil-oxidizing microorganisms were up to 60 % of the heterotrophic bacteria number. The hydrocarbons content exceeded the maximal permissible level: 3.6 and 4.5 MPL in Muchke and Toki Lakes, respectively. Both estuaries were subjected to chronic hydrocarbon pressure.

Abstract The quality of municipal water supplies is of fundamental importance to public health and national security. Here, we assess the tap water quality in 31 provinces across China and examine the effects of natural and anthropogenic conditions on water quality and associated health risks. Precipitation is a crucial factor influencing the organic matter content and ionic conductivity in tap water, especially for arid and semi-arid regions. Although the concentration of disinfection byproducts (DBPs) is closely related to the organic matter content, the occurrence of highly toxic DBPs was more significantly affected by anthropogenic factors such as economic development and pollution emission. We confirmed nanofiltration as an effective point-of-use treatment to reduce the adverse effects of DBPs in public water supplies. Since DBPs in tap water is a long-term global problem, our results highlight the potential health hazards of drinking water brought about by social development and conclude that countries and regions with rapid development might face high DBP toxicity.

A 7.5 cm layer (.1 m3) of fresh or 8-year-old oak sawdust was applied to 1.7 m2 plots as a mulch or tilled in to a depth of 10 cm. Saw dust-treated and control plots received 0.45 or 227 g of nitrogen applied as ammonium nitrate. Five one-year-old `Lynwood Gold' forsythia plants were planted in each of the 90 plots in the experiment in September 1992 and were pruned in March 1993 to 20 cm above the soil surface. Plant height, soil pH and levels of Na, organic matter, P, K Ca, Mg, NO3 and NH3 in the soil were determined following the 1993 growing season. Fresh and aged saw dust reduced plant growth by 40 and 31% respectively when incorporated without supplemental nitrogen. Adding the high rate of nitrogen overcame the inhibition caused by aged but not fresh sawdust. Both materials significantly reduced soil nitrate content even when used as a mulch and reduced phosphorus when incorporated. Organic matter content of sawdust-amended plots averaged over twice that of control plots. Neither material had a significant influence on pH as determined one year after incorporation.
