increasing the concentration of ammonia in water can cause fish death. this study was conducted to compare the performance of conditioned activated carbon and zeolite in ammonia (tan = total ammonia nitrogen) removal in a simulated transport of rainbow trout fry in 40-liter plastic bags. hence, responses of zeolite and conditioned activated carbon in ammonia (tan) removal at different concentra...

Abstract Methylene blue dye discharged from the textile industries is a thiazine which toxic and non-degradable chemical. Activated carbon mostly used adsorbent to effectively remove industrial waste waters. Low-cost adsorbents like groundnut shell powder neem were for component level present in solution as batchmode treatment concentration of 200mg/litre fixed 0.5 grams Adsorbent I (Neem seed ...

The activated sludge process is one of the most important parts of conventional wastewater treatment plants. Wastewater is treated biologically in activated sludge basins. Activated sludge can remove soluble contaminants, primarily organics compounds and nitrogen, from the wastewater stream. The activated sludge is a mixture of microorganisms, inorganic and organic compounds aggregated to flocs...

In this study, we prepared activated carbon from coconut shell with a low activating time for (AC). The powder (< 100 µm) allows an effective pyrolysis process and activation (30 min) that reduces the cost of production. AC has characteristics micropore average size 1.9 nm surface area 460.50 m2/g. For supercapacitor electrode, electrodes have capacitance 50, 66, 67.5 F/g when 0.5 M, 1 2 M N...

Quantitative structure-property relationship (QSPR) for estimating the adsorption of aliphatic alcohols onto activated carbon were developed using substructural molecular fragments (SMF) method. The adsorption capacity of activated carbon (gr/100grC) for 150 aliphatic alcohols onto activated carbon (AC) is studied under equilibrium conditions. Forward and backwards stepwise regression variable ...

Polyvinylchloride (PVC) based heterogeneous cation exchange membranes were prepared by the solution casting technique. The effect of super activated carbon nanoparticles concentration as filler additive in membrane matrix on ionic transfer behaviors of the membrane was studied. SOM images showed uniform particles distribution and relatively uniform surfaces for the membranes. The membrane water...
