Kinetics Coefficient of Palm Oil Clinker Media for an Attached Growth Media in Sequencing Batch Reactor Mode

Kuan Yap Zhi, Kutty Shamsul R. M., Ghaleb Aiban A. S.

Journal of Ecological Engineering

Vol. 20, nr 9

Palm oil clinker media (POCM), which is a by-product of incineration process from palm oil industry, creates environmental sustainability issues. This is due to the method of handling solid waste material of industry by simply dumping it on an open land area. The previous study of POCM including physical and mechanical properties of solid present showed promising results of utilizing POCM as a packing media for treatment of domestic wastewater industry. The packing media can be used in the process of biological wastewater treatment system in Sequencing Batch Reactor (SBR) mode. By adopting POCM as an attached growth media, this research paper focuses on the performance of POCM in SBR mode in the context of organic and nutrient removal rate. The performance pertaining to the removal of organics and nutrient was measured using USEPA Standard Method for Chemical Oxygen Demand (COD) and Ammonia. The average rate of removal for COD and Ammonia per biomass adopting POCM in sequencing batch reactor mode is 0.0069 mg COD/mg MLVSS and 0.001 mg Ammonia/mg MLVSS.

Ostwald ripening of nanoislands in semiconductor heterosystems and its influence on optical properties

Vengrenovich R. D., Ivanskii B. V., Moskalyuk A. V.

Opto-Electronics Review

2010

Vol. 18, No. 2

168-175

Influence of the Ostwald ripening on character of the size distribution in semiconductor heterosystems with quantum dots as island films consisting of cylindrical, disclike islands of constant height is studied. Size distribution function and formulae for temporal changes of average island size are derived. Calculations are carried out within the LSW theory, in assumption of joint action of two (diffusion and Wagner) growing mechanisms. Comparison of the calculating results with experimental data proves validity of the accepted model approximations. Expectancy of correlation of the distribution function, growing mechanisms and properties of heterosystems is discussed.
