Abstract This paper presents an analysis of the wastewater treatment plants in six Latin American and Caribbean countries. Based on a sample 2734 municipal facilities, applied processes are classified by sizes (influent flow) type technologies. The distribution technologies is also presented for each In addition, representative characterization, based influent data from 174 plants, proposed. Results show that stabilization ponds, activated sludge, upflow anaerobic sludge blanket reactors...
Anaerobic treatment of terephthalic acid plant wastewater was tested using two UASB reactors (T and U) a downflow tubular fixed film reactor. T inoculated with sludge sampled from an anaerobic stabilization pond receiving waste activated petrochemical industry plant. U the reactor were anaerobically adapted municipal Raw effluent had to be settled neutralized before feeding. Sedimentation resulted in 70% TSS 37% COD removal. digesters presented comparable efficiencies rather low removals:...
Two different sludge retention times (SRTs) were tested in order to assess the impact on membrane fouling and effluent quality an anaerobic bioreactor (AnMBR). up-flow bed (UASB) reactors (1 l volume) coupled external tubular ultrafiltration membranes (filtration area = 81 cm2) operated at a hydraulic time of 3 h two SRTs (100 60 days). The transmembrane pressure (TMP), flux (J) relevant parameters water measured. Effluents from UASB filtered for 500 without intermediate cleaning. permeate...
A laboratory UASB reactor was fed with cane molasses stillage at organic loadings from 5 to 21.5 kg COD/m3 d. With an load of 17.4 d, accumulation VFA, principally propionic acid, observed due little bioavailability or lack trace metals (Fe, Ni, Co and Mo). Associated this, the performance low (44% COD removal efficiency), alkalinity ratio above 0.4. The addition Fe (100 mg/l), Ni (15 (10 mg/l) Mo (0.2 influent reduced significantly level acid (5291mg/l 251 acetic (1100 mg/l 158 mg/l)....
The combined effect of carbon source and nitrogen loading rate (NLR) on denitrification sludge granular settleability in upflow anaerobic blanket (UASB) bench-scale reactors was studied. Acetate, lactate glucose were used as sources for denitrification. Three NLR evaluated: 500, 1000 2000 mg NO3−-N/ld. It found that NO3−-N consumption efficiency 99% all the cases. Denitrification efficiencies high (85-96%) substrates tested, but specific denitrifying rates a better representation process....
The combined and individual effects of aluminium sulphate at concentrations 1,000 mg/l as Al(OH)3, 150 mgSO4(2-)/L K2SO4, respectively, on the anaerobic digestion sludge from enhanced primary treatment (EPT) were evaluated in 1 L capacity semi continuous reactors. It was found that 59 days, inhibits specific methanogenic activity (SMA) acetogenic bacteria resulting a 50% to 72% decrease. Sulphate also (48% 65%) SMA same type bacteria. Methanogenic able adapt, different extent, assayed...
