Effects of sponge pore-size on the performance of a down-flow hanging sponge reactor in post-treatment of effluent from an anaerobic reactor treating domestic wastewater

A bench scale study was carried out in order to evaluate the applicability of dissolved air flotation (DAF) as an advanced treatment for effluents from three different domestic wastewater treatment processes, namely: (i) a tertiary activated sludge plant ; (ii) an upflow sludge blanket anaerobic reactor (UASB); and (iii) a high-rate stabilization pond.

An anaerobic reactor was developed to biodigest alcohol distillery wastes. A further post-treatment of the effluent reduced the level of pollution to the point of eventually discharging into streams and rivers. The present work also analyses the use of biodigested vinasse as a source of food for fish. Very high efficiencies were obtained during primary and secondary treatment of vinasse effluent, as demonstrated by the greatly reduced organic load. The utilization of the treated effluent as a source of fish food presents an excellent alternative for the Brazilian alcohol industry.

Research on allophane has been done as an adsorbent to decrease MPN Coliform in domestic wastewater. The purpose of this study was to look for natural adsorbent materials that can be used to decrease MPN Coliform. Natural allophane was identified from andisol soil by pH analysis of NaF, FTIR, XRD, and SAA. The result of the analysis showed that there was allophane on andisol soil with pH 11,73. The diameter of empty space or alloy pores of 5 nm with a hole/pore size of 0.5 nm. Testing of MPN Coliform is done by method of Most Probable Number (MPN) variety 5: 5: 5. Based on the result of the research, allophane adsorbent can decrease MPN Coliform by 60.9%.

Sludge Production

This paper describes the performance, sludge production and biofilm characteristics of a full scale fluidized bed anaerobic reactor (32 m3) for domestic wastewater treatment. The reactor was operated with 10.5 m.h-1 upflow velocity, 3.2 h hydraulic retention time, and recirculation ratio of 0.85 and it presented removal efficiencies of 71 ± 8% of COD and 77 ± 14% of TSS. During the apparent steady-state period, specific sludge production and sludge age in the reactor were (0.116 ± 0.033) kgVSS. kgCOD-1 and (12 ± 5)d, respectively. Biofilm formed in the reactor presented two different patterns: one of them at the beginning of the colonization and the other of mature biofilm. These different colonization patterns are due to bed stratification in the reactor, caused by the difference in local-energy dissipation rates along the reactor's height, and density, shape, etc. of the bioparticles. The biofilm population is formed mainly of syntrophic consortia among sulfate reducing bacteria, methanogenic archaea such as Methanobacterium and Methanosaeta-like cells.

Objetivou-se com este trabalho avaliar os efeitos da irrigação com água residuária doméstica tratada e da adubação com composto de resíduo sólido urbano na matéria seca de plantas de girassol. O experimento foi conduzido em casa de vegetação na Universidade Federal de Campina Grande – PB; a cultura utilizada foi o Girassol (Helianthus annuus L.), variável EMBRAPA 122/V2000, cultivadas em vasos preenchidos com solo classificado como Neossolo Regolítico eutrófico. O delineamento experimental foi em blocos inteiramente casualizados em esquema fatorial 6 x 2, com 3 repetições, que foram 6 doses de nitrogênio disponível em composto de resíduo sólido (0, 60, 100, 140, 180, 220 kg. N. ha-1) e 2 tipos de água (água de abastecimento e água residuária doméstica tratada). A água residuária foi tratada por meio de reator UASB (Reator anaeróbico de fluxo ascendente) e a água de abastecimento foi proveniente do sistema de abastecimento público municipal. Verificou-se que a qualidade de água influenciou a produção de massa seca da parte aérea a 5% de probabilidade; já a variação das doses de nitrogênio não exerceu efeito significativo para a variável analisada.Effect of organic manure on the dry matter of the sunflower irrigated with wastewaterAbstract: is aimed with this work was to evaluate the effects of irrigation with treated domestic wastewater and fertilization with municipal solid waste compost on the dry matter of sunflower plants. The experiment was conducted in a greenhouse at the Federal University of Campina Grande - PB; culture used was the Sunflower (Helianthus annuus L.), variable EMBRAPA 122 / V2000, grown in pots filled with soil classified as eutrophic Entisol. The experimental design was randomized blocks in a factorial 6 x 2, with three repetitions, which were 6 levels of nitrogen available in compound of solid waste (0, 60, 100, 140, 180, 220 kg. N ha-1) and 2 types of water (water supply domestic wastewater and treated water). The wastewater was treated by UASB (upflow anaerobic reactor) and the water supply was coming from the municipal supply system. It was found that the water quality influenced the dry matter yield of shoot a 5% probability; since the variation of nitrogen doses no significant effect for the variable analyzed.
