This paper reports the results obtained during an investigation aimed at transferring to the demonstrative scale an aerobic granular biomass system (SBBGR--Sequencing Batch Biofilter Granular Reactor) integrated with ozonation for the efficient treatment of tannery wastewater. The results show that the integrated process was able to achieve high removal efficiencies for COD, TSS, TKN, surfactan...

this study presents the natural dye recovery from various biodegradable temple and household wastes. the raw material for colour extraction consisted residual flowers and garlands from various temples as well as onion and vegetables peels from vegetable markets, university hostels, and households, which were washed, dried, crushed, and sieved. the extracted natural colours were produced by mean...

A dispersed-ozone flotation (DOF) separator was devised for a pilot study of tertiary wastewater treatment for re-use purposes. As a compact device combining coagulation, ozonation and flotation in an integrated unit, the DOF separator achieved a very high removal of SS, TOC, UV254 and colour, as well as effective inactivation of coliform and total bacteria within a short hydraulic retention ti...

The discoloration of a biologically pretreated waste water stream from a molasses processing by ozonation and two advanced oxidation processes (O3/H2O2 and 03/7-irradiation, respectively) was studied. Colour removal occurred with all three processes with almost the same efficiency. The main difference of the methods applied was reflected by the BOD increase during the discoloration period. By o...

The bucket reactors based wetland system were adopted for the treatment of pulp and paper mill wastewater using two macrophytes namely Typha angustifolia and Canna indica. The study was carried out for the treatment of wastewater collected from primary clarifier overflow (E1) and wastewater after the partial aerobic treatment of primary clarifier overflow (E2). Effectiveness of the two macrophy...

Shadow will occur by sunlight or any light sources. In the area of machine vision, shadows occur frequently in a wide variety of scenes. In many cases, this is undesirable due to the fact that they often lead to the result of irretrievable processing failures. In this paper, we introduce a novel shadow detection and removal technique that produces a shadow-free scene. In this method, shadow fea...

+ ve G) were countered with limited success by pressure suits, horizontal posture, etcUpward forces (i.e. ve G) were less well tolerated. Whereas the former caused first greying out due to loss of colour vision, then blacking out and final unconsciousnessi recovery usually took place on removal of the stress in good time. On the other hand* with negative G a red out occurred, leading to cerebra...

A beautiful smile is dependent on many factors. One of those factors is the gingival scaffold. Symmetry, proportion, as well as colour and appearance of the gingiva are critical to an aesthetically pleasing smile. Physiological gingival hyperpigmentation does not present as clinical pathology requiring intervention, nonetheless it may be of aesthetic concern to the patient. Minimally invasive i...

Two synthetic aperture radar (SAR) datasets with validated icebergs in sea ice were analyzed. A qualitative assessment of the data using false colour visualization methods for dual polarization SAR was conducted indicating that icebergs had an improved visually discernable signature from the background over single polarization SAR.A quantitative analysis was completed to exploit these observati...
