چکیده

Leachate waste from piles of garbage in the landfill (TPA) has a high concentration Chemical Oxygen Demand (COD). High COD concentrations can cause decrease dissolved oxygen waters. Simple leachate treatment is carried out using adsorption method with adsorbents derived food waste. This research used Precipitated Calcium Carbonate (PCC) adsorbent ale-ale shells. study aims to evaluate effect particle size and calcination temperature variations on PCC yield analyze ability reducing concentrations. In addition, was characterized an infrared spectrophotometer (FTIR) X-ray diffractometer (XRD). Determination by permanganometric titration. The optimum 57.75% obtained Ale-ale shells 40 mesh 800 ° C. functional groups are C-O at wave numbers 1403 cm -1 , 873 713 . XRD characterization showed presence calcite phase peak intensity 2 = 29.38 organic matter (4.5 g/50 mL) stirring speed 200 rpm for 240 minutes reduced 1131.28 mg/L 456.94 efficiency 59.61%

Effect of Hydraulic Activity on Crystallization of Precipitated Calcium Carbonate (PCC) for Eco-Friendly Paper

Wt% of aragonite, a CaCO(3) polymorph, increased with higher hydraulic activity ( degrees C) of limestone in precipitated calcium carbonate (PCC) from the lime-soda process (Ca(OH)(2)-NaOH-Na(2)CO(3)). Only calcite, the most stable polymorph, was crystallized at hydraulic activity under 10 degrees C, whereas aragonite also started to crystallize over 10 degrees C. The crystallization of PCC is ...

Navier - Stokes ALE free

Droplet impact onto a solid surface is modeled and numerically simulated using an ALE formulation of the Navier-Stokes free surface equations. The triple line dynamics aspect is modeled implicitely through the Shikhmurzaev theory. Those equations involve a generalized Navier slip boundary conditions with the variation of the surface tension near the triple line (thus a local Marangoni effect). ...

ALE Mesh Updating using Mesh Optimisation

Accurate numerical simulation of problems in fluid mechanics requires using a method whereby the mesh can track free surfaces or fluid-solid or fluidfluid interfaces whilst coping with large distortions of the continuum. Such methods are referred to as Arbitrary Lagrangian Eulerian (ALE) methods and may be furthered studied in [1]. In order for the mesh to adapt to the deforming domain, a mesh ...
