Textile, printing, and other related industries are facing problems of treatment and disposal of dye wastewater. Adsorption experiments Removal of organic matter (COD) from the wastewaters with varying amounts of adsorbent (1-5g/100ml) was studied keeping pH (11.83) and agitation time (1h) constant. In wastewater treatment plants (WWTPs), adsorption processes are applied for the removal of dissolved pollutants that remain from the subsequent biological phases or after chemical oxidation treatments. adsorption process of 2,4,6-trichlorophenol in wastewater using coconut shell-activated carbon,11 and found that Langmuir model could describe the process of adsorption on coconut shell-activated carbon. The activation temperatures were selected at the range of 200–300 °C. 1. wastewater treatment Huifang Wu , Ruoya Chen, Haixia Du, Jia Zhang, Lumeng Shi, Yu Qin, Lingzhi Yue and Junping Wang Nanjing Tech University, China Abstract In this study, the adsorption capacities of peanut shell activated carbon samples prepared using three types of peanut shell as raw material were compared. the adsorption processes. However, using spent coconut husks can be a cheap, environmentally friendly alternative source of AC for removing nitrogen and phosphorus in the secondary effluent. Today, the most commonly adopted adsorbent is the activated carbon. The adsorption process is endothermic with a maximum adsorption of 83 percent at 30 o C for an … Adsorption takes place when molecules in a liquid bind themselves to the surface of a solid substance. INTRODUCTION Increased use of metals and chemicals in process industries has resulted in generation of large quantities of effluent that contain high level of toxic heavy metals and their presence pose environmental-disposal problems MATERIAL & METHODS Experimental Setup In the study of present work, an adsorption study with coconut shell … The adsorption of methylene blue could be best described by the pseudo-second-order equation. This research is studying ammonia concentration, COD, alkalinity, VFA, ammonia removal and COD removal after incubation 7 days. Key words: Batch adsorption, heavy metals, wastewater, coconut husk. The adsorption experiments showed that the adsorption temperature, contact time, initial pH, and the adsorbent dosage had a great influence on the adsorption performance of diesel oil by crab shell biochar, and optimal experimental conditions were: temperature = 30 °C, adsorbate dosage = 0.2 g, pH = 7, contact time = 4 h. Mubarik et al. Adsorption of heavy metal on the solid surfaces is an important technique to remove them from the industrial wastewaters. 1 CivilEngineering Department Z.H. Thus, peanut shell can be used to prepare activated carbon for wastewater treatment. Adsorption is most commonly implemented for the removal or low concentrations of non-degradable organic compounds from groundwater, drinking water preparation, process water or as tertiary cleansing after, for example, biological water purification. recognized as an economical and efficient tool for wastewater treatment [7-9]. Adsorption has advantages over the other methods because of simple design and can involve low investment in term of both initial cost and land required.

This study considered thermal and non-thermal, chemical activation methods to create four different AC treatments. The activated carbon surface is non-polar which results in an affinity for non-polar adsorbates such as organics. The extant of removal was found to be dependent on pH, contact time, adsorbent dose, concentration of metal and particle size. Treated wastewater should as good as normal water.
