BACKGROUND High salinity (1-10% w/v) of tannery wastewater makes it difficult to be treated by conventional biological treatment. Salt tolerant microbes can adapt to these saline conditions and degrade the organics in saline wastewater. RESULTS Four salt tolerant bacterial strains isolated from marine and tannery saline wastewater samples were identified as Pseudomonas aeruginosa, Bacillus fl...

Starch sludge (SS) is a bulky main waste from modified tapioca starch production, high potential substrate for alternative volatile fatty acids (VFA) production. Because it has relatively organic content in SS easy and fast to convert into VFA. However, there are limitations when fed overloading rate anaerobic digestion (AD) system affecting the VFA production yield performance. This research a...

Experiment aims to determine the substitution effect of tapioca by purple sweet potato flour on antioxidant, fat oxidation, content and pH Manila duck sausage. Completely randomised design with 5 treatments 3 replications was applied in this experiment. Those treatment were: P0 = 100% tapioca; P1 25% + 75% P2 50% P3 dan P4 flour. Variable measured pH. The result showed that have close significa...

Erratum: “Radionuclides in Fracking Wastewater: Managing a Toxic Blend” The Focus article “Radionuclides in Fracking Wastewater: Managing a Toxic Blend” [Environ Health Perspect 122:A50–A55 (2014); http://dx.doi.org/10.1289/ehp.122-A50] incorrectly stated that Pennsylvania requires pit liners for temporary impoundments and disposal to have a minimum thickness of 30 mm. The correct minimum thick...

This paper reported the pollutant removal performances of a hybrid wetland system for the treatment of aquaculture wastewater. The system consisted of two treatment stages: a subsurface vertical flow (VF) wetland, followed by a horizontal flow (HF). The aquaculture wastewater with the different concentrations such as eutrophy and mesotrophy was treated using hybrid constructed wetland. The expe...

In many regions of the world, urban water systems will need to transition into fundamentally different forms to address current stressors and meet impending challenges-faster innovation will need to be part of these transitions. To assess the innovation deficit in urban water organizations and to identify means for supporting innovation, we surveyed wastewater utility managers in California. Ou...

Eight Holstein steers (439 kg) with "T" cannulas in the rumen and proximal duodenum were used to evaluate the characteristics of digestion of Pima cottonseed. Treatments consisted of a basal growing-finishing diet containing (DM basis) 1) 15% tapioca, 2) 15% whole linted cottonseed (Delta Pine 61, DP); 3) 15% whole lint-free cottonseed (Pima, PW), and 4) 15% ground Pima cottonseed (PG). Substit...
