Utilization Potency of Extracellular Polymeric Substance as Industrials Biosorbent And Ion Exchange Resin - Diponegoro University | Institutional Repository (UNDIP-IR)

Industrial contaminant cations and anions can be removed from water and or waste water by using ion exchange resin. Extracellular Polymeric Substances (EPS) resulting from bacteria can accumulate the elements ions from its external environment by biosorption accumulation mechanisms of adsorption, ion exchange, complex formation, and hydrogen bound. The ions exchange can accurs by supporting of negatively and positively functional groups in EPS. The EPS can be utilized as biosorbent and ion exchange resin for replacing the commercial organic ion exchange resin. The EPS is composed of polysaccharides (40-95%), protein (1-60%), nucleic acid (1-10%), lipids (1-10%), and polymers of amino acids and other compounds of microbial origin. The study of EPS utilization as biosorbent and ion exchange resin has been performed. The EPS was extracted from industrial activated sludge by 6,000 rpm centrifugation at 4 o C. From its analysis, the resulted EPS contains polysaccharides 60 %, protein 8 %, and lipids 16 %. The tests of resulted EPS biosorption capabilities have been done by dispersed EPS operation on the simulation radioactive liquid waste containing lead 4 x 10 4 Bq/l, uranium 4 x 10 4 Bq/l and thorium 4 x 10 4 Bq/l. The EPS performs normally the biosorption of contaminants by sequence of its selectivity i.e. Pb +2 > Th+4 > UO 2

Lactic acid and their esters are used in food industry for preservation and flavoring purposes, as well as in the pharmaceutical and cosmetic industries [9]. Sanz et al [17, 18] studied the ion exchange resin catalyzed esterification of lactic acid with methanol and ethanol and reported that Amberlyst 15 is most suitable catalyst for the reaction. Zang et al [19] investigated the esterification of lactic acid with ethanol in the presence of five different cation exchange resins. Their investigations indicated that pseudo homogeneous second order model was the most appropriate model to describe the kinetic behavior. Studies on esterification reaction of lactic acid with isopropanol has been done by Yadav et al [3] over Amberlyst 36 at higher molar ratios of reactants (i.e. lactic acid to iso-propanol upto 1:44).

LIQUID RADIOACTIVE WASTE STUDY BASED ON VARIOUS ADSORBENTS. Liquid radioactive waste could generate from the washing process of contaminated equipment and unused liquid radioactive substances. In 2014 Center for Radioactive Waste Technology (CRWT) received 64.240 litres of radioactive waste from reactor activity which mostly consist of Cs-137 and Co-60. Radioactive waste treatment at CRWT is done using evaporation method. If during the treatment process, a malfunction at the supporting apparatus such as the media and power availability occurred, the radioactive waste treatment process will be halted.bThe obstacle has to be overcome by developing another method as the support of the existing treatment method. The study to find an alternative method of radioactive treatment using adsorbent was done by investigating the available literatures that based on method similarity employed in several countries. This the tudy from several countries found that the radioactive waste treatments that commonly used are zeolit, ion exchange resin, bentonit and its modifications. Economically, the zeolit is much better to utilize since it is a natural resource and has an abundant availability. The zeolit and resind are absorbent that has relatively high KTK value compare to other absorbents, which is 0,9 – 2,2 meq/g. Based on the liquid radioactive waste characteristic that process at CRWT, the suitable adsorbent to utilize are zeolit and resin. Results of the study can be applied to further study at laboratory scale using the existing radioactive waste that process at CRWT. Therefore, the method that found in the study is applicable at CWRT.

PRELIMINARY STUDY OF BEHAVIOR OF SILICA IN THE PRIMARY COOLING WATER REACTOR RSG-GAS . The primary cooling water as a moderator and the media heat transfer of result of the fission reaction in the reactor core. The water coolant will interaction directly with the material component or structure of the reactor, so that will allow chemical reactions between water and the material component or structure of the reactor which can cause corrosion or scaling. Silica in cooling water can cause deposits that can form scaling on the surface of the metal so that the lower the heat exchange efficiency. Study of the silica content in the primary cooling water has been conducted. Preliminary studies conducted by monitoring the content of silica in the primary cooling water after the replacement of ion exchange resin purification system and the content of silica in the demineralized water as it is used as the primary cooling system supply.From the results of the study showed that the silica content in the initial condition after the replacement of ion exchange resin purification system decrease or showed small numbers( ranges from 0.1 ppm) even though the silica content in demineralized water is used as the primary coolant system supplier shows that large numbers( ranges from 20 ppm). This shows that the ion exchange resin can be used to remove silica in water. However, with the increase in the use of time, the silica content increases is allegedly due to the leaked silica which was originally bound to the ion exchange resin of purification system.

Water Treatment Program Manual 6 Th Revi

Water Treatment Program Manual 6 Th Revi

The Cation exchange resin has a positive charge and is normally associated with the softening process. This resin is also known as Sodium Zeolite and is typically the strong acid type. The resin is made of tiny polystyrene beads which have positively charged sodium ions loosely attached. These Sodium Ions will be readily given up for more desirable positive Ions such as Calcium and Magnesium. This exchange will continue until all possible sodium Ions have gone. At this point the resin beads are exhausted and need a new charge of sodium Ions. This is accomplished by reversing the softening reaction. A calcium chloride brine solution (salt) is introduced to the exhausted resin to remove the Calcium and Magnesium and restore the Sodium Ion on the resin bead once again. This is called the regeneration cycle and repeats continuously as needed.

Ion-exchange process for ammonium removal and release using natural Iranian zeolite

Ion-exchange process for ammonium removal and release using natural Iranian zeolite

The loss of nitrogen (N) from applied N fertilizer due to leaching, volatilization, and denitri fi cation leads to not only a decrease in N fertilizer ef fi ciency, but can also result in air and groundwater contamination (Cassman et al., 2002; Owens et al., 1992). Reduction in such loss has been one of the major issues in both agricultural and environmental studies. Among the approaches, the application of zeolites as a soil amendment to improve the physical and chemical properties of soil and to reduce the loss of nutrients and water has attracted intensive attention (Boettinger and Ming, 2002; Park and Komarneni, 1998). Natural zeolites are hydrated aluminosilicates with symmetrically stacked alumina- and silica tetrahedral which result in an open and stable three-dimensional honeycomb structure (Maranon et al., 2006) possessing high cation exchange capacity (CEC), cation selectivity, higher void volume, and a great af fi nity for NH 4 + (Dixon and
