Microbiological diversity in an aerated lagoon treating kraft effluent

The microbiological diversity of cultivable bacteria was analyzed in an aerated facultative lagoon. The removal of specific compounds and measures of pollutant load was evaluated with isolated native bacteria, selected and identified in kraft cellulose effluent. The system was operated with an organic loading rate of 0.2 kgCODm-3d-1 for 60 days. Analyses of the fluorescence excitation-emission matrix, acute ecotoxicity, and microbiology were performed. Bioaugmentation tests were done to emphasize the removal of color, using promising species. The removals of biochemical oxygen demand, chemical oxygen demand, and total organic carbon in AFL were 94%, 51%, and 41%, respectively. Regarding color, removal was up to 4%, and the total phenolic compounds were not removed through biological treatment. The treatment also decreased turbidity by 94% and lignin derivatives by 12%. The bacteria identified through NCBI-BLAST and statistical similarity totaled 9 species in the cellulose effluent, three of which have the potential for color treatment: Bacillus cereus, Bacillus thuringiensis, and Paenibacillus sp. The Bacillus cereus combined with biomass removed color (69%), total phenolic compounds (37%), and compounds derived from lignin (53%). These species are promising for removing specific parameters combined with biomass from biological AFL treatment systems.

Advanced Oxidation of Segregated Streams for Effective Color Removal from Denim Processing Effluents

The study introduced footprint analysis as a new methodology and focused on differentiating wastewater streams with the highest color content and optimizing the advanced oxidation process for the segregated streams for effective color removal from denim processing. Experiments were implemented to four segregated streams rather than the entire plant effluent. A flow proportional composite mixture of segregated streams was used for color removal experiments using the advanced oxidation process with ozone and hydrogen peroxide and Fenton oxidation as other alternatives. The latter yielded the best results achieving total removal of color below visual detection limit after an optimum reaction time of 10 minutes. The Fenton oxidation process was also applied to a representative sample from the plant effluent after the physical-chemical treatment sequence, where color absorbance levels were lowered at all wavelengths below 1.0 m-1. The merit of the new footprint approach was confirmed by the results, which provided a conclusive indication that color treatment at source, implemented on selected segregated wastewater streams, presented concrete advantages over the end of pipe treatment of the overall effluent.

Evaluation of Physical quality of alang-alang (Imperata cylindrical) fermentation as fed greenswamp buffalo

The objectives of this study were to evaluate the physical quality of alang-alang (Imperata cylindrical) fermented using Banana Weevil Mol pH, color, aroma and texture. This research method using experimental methodswith completely randomized desig consists of 6 treatments repeated 3 times. L1 : Banana Weevil Mol 20 ml L2 : Banana Weevil Mol 25 ml L3 : Banana Weevil Mol 30 ml L4 : Banana Weevil Mol 35 ml L5 : Banana Weevil Mol 40 ml L6 : Banana Weevil Mol 45 ml.The results obtained were analyzed using analysis of variance and then the BNJ continued test. Based on the results of this study, it was shown that the physical quality of reeds fermented using banana weevil moles had a very significant effect (P <0.01) on pH parameters.significant effect (P <0.05) on color treatment and no significant effect (P> 0.05) on aroma and texture treatment parameters.Based on the research, it can be concluded that evaluating the physical quality of Imperata in the 35 ml L4: Banana Weevil Mole treatment gave the best results in all observation parameters.

Prayang Innovation Technology on Capture Results

Prayang is traditional fishing gear, a prohibition on the use of cantrang fishing gear by the Ministry of Maritime Affairs and Fisheries (KKP) requires an alternative replacement fishing gear, considering that the condition of the Java sea waters is already overfished. The study aims to determine the effect of using different color lights on prayang fishing gear on catches. The research method is an experiment by applying "light fishing" technology. The initial stage of the study was the use of lighting aids with different colors. Based on the results of statistical tests the lamp color treatment had no significant effect, the catch was dominated by white shrimp species for the use of white light and the shrimp continued to prefer green.

Evaluating the possibility of color treatment of Tarcon Blue 2BLN dye by coagulating materials PGa21Ca, polyaluminium chloride, iron (II) sulfate heptahydrate and aluminium sulfate octadecahydrate

This article presented the results of color treament ability of Tarcon Blue 2BLN dye with some flocculation chemicals such as PGa21Ca, polyaluminium chloride (PAC), iron (II) sulfate heptahydrate (FeSO4.7H2O) and aluminium sulfate octadecahydrate (Al2(SO4)3.18H2O). Our results showed that conditions for treatment the color to reach column B, QCVN 13: 2015 / BTNMT (national technical regulation on textile and dying industry) by different flocculation chemicals were the same exposure time (10 minutes), sedimentation time (30 minutes), but different in parameters of concentration (% mass), stirring speed and pH. Specifically: PGa21Ca (0.02%), PAC (0.01%), aluminium sulfate octadecahydrate (0.003%) can handle color at the initial pH of the solution (pH = 6), with the stirring speed corresponding to each flocculation chemical at 120 rpm, 45 rpm and 45 rpm respectively. In contrast, with iron (II) sulfate heptahydrate (0.02%), only the color treatment reaches column B, QCVN 13: 2015 / BTNMT when the pH of the wastewater raises to 10 and stirring speed is 120 rpm. Compared with PAC, aluminium sulfate octadecahydrate and iron (II) sulfate heptahydrate, PGa21Ca has the advantage of contributing to raise the pH value in the acid solution, which reduces the pH in the base environment, and not changing the pH when the concentration of PGa21Ca increases. Test results on actual wastewater samples taken from Hoa Khanh Danang Textile Joint Stock Company (DANATEX) showed that the ability of treating color of these chemicals on actual wastewater samples is lower than the ability on water samples blended with Tarcon Blue 2BLN dye.
