The current study aimed at fostering bacterial growth in BFT aquaculture tanks by early Nile tilapia stocking. Control had no but received daily applications of dry molasses (NT+) or C:N ratio adjustment (T-). Experimental and application to adjust the water 15:1 (T+). development bioflocs NT+ was insignificant as demonstrated low levels settleable solids (SS) total suspended (TSS). Total ammon...

Pollution reduction in the Conasauga River is a high priority for Georgia due to the remaining biological diversity of the Conasauga. Home to 76 native species of fish, more than the Columbia and Colorado Rivers combined, the Conasauga serves residential, agricultural, and carpet industry needs in and around Dalton. Segments of the river are impaired due to sediment, nutrients, and fecal colifo...

Irrigation is a dry season agricultural activity that was known to man for centuries. Agricultural runoff has been identified as the major nonpoint sources of pollution into surface waterbodies which changes physico – chemical parameters thereby impacting on biodiversity such ecosystem. River Ngadda receives pollutants from irrigational sites along river bank. The study aimed at assessing impac...

The paper investigates the dynamic behaviour of Inverse Fluidized Bed (IFB) for treatment petroleum wastewater using adsorbents date seed activated carbon (DSAC) and commercial coconut shell (CCAC). fluidization is downward flow technique, where density particles are less compared to liquid density. IFB wasexperimentally validated by analysing chemical oxygen demand (COD) removalefficiency, tot...

Total suspended solids (TSS) are sediment material that floats in the water column moves without touching bed, influenced by input from land, river flow, and oceanography factors. TSS is closely related to sedimentation, which can harm aquatic ecosystems, especially coral reefs. This research was conducted using data as well flow for each season (May, June, October 2019, February March 2020) kn...

In conventional wastewater treatment, biological nutrient removal (BNR) depends on bacterial assimilation for phosphorus removal and nitrification+denitrification for nitrogen removal, with the resulting loss of the fixed nitrogen resource. Alternatively, treatment by microalgae allows for assimilative removal of both phosphorus (P) and nitrogen (N) thereby avoiding the oxygen demand of nitrifi...

Pendangkalan PPN Pemangkat akibat sedimentasi sudah menjadi perhatian sejak beberapa tahun terakhir. Penelitian ini dilakukan untuk mengidentifikasi 3 sumber yang berasal dari Sungai Sambas Besar, Prapakan Tanjung, dan Penjajap menentukan dominan penyuplai sedimen di dalam area pelabuhan. Data digunakan yaitu elevasi pasang surut, arus, debit aliran sungai, konsentrasi TSS. Hasil penelitian men...

Nitrifying bacterial community structures of suspended and attached biomasses in a full-scale integrated fixed-film activated sludge process were investigated by analyzing 16S rRNA gene sequences obtained from pyrosequencing. The suspended biomass had a higher number of ammoniaoxidizing bacterial sequences (0.8% of total sequences) than the attached biomass (0.07%), although most of the sequenc...

This laboratory work examines the relationship between turbidity (NTU) and total suspended sediment concentration (TSS, mg/L) for a Cecil Ap soil, a common Southeastern Piedmont soil type. We show a 1:1 correlation between NTU and TSS for the silt and clay fractions, but a smaller ratio for clay and bulk-soil samples. These results suggest that NTU measurements can be used to estimate sediment ...

Spectra, salinity, total suspended solids (TSS, in mg/L) and colored dissolved organic matter (CDOM, ag(400) at 400 nm) sampled in stations in 44 different locations on December 18, 19 and 21, in 2006 were measured and analyzed. The studied field covered a large variety of optically different waters, the absorption coefficient of CDOM ([ag(400)] in m(-1)) varied between 0.488 and 1.41 m(-1), an...
