Biodegradation of Isothiazolone Biocide by a Laboratory-Scale Rotating Biological Contactor

Sirikhansaeng, Prapaparn; Laopaiboon, Pattana; Vichitphan, Kanit; Laopaiboon, Lakkana (มหาวิทยาลัยราชภัฏบุรีรัมย์, 2007-11)

The aim of this study was to investigate the effects of operating conditions (organic loading rate, OLR; hydraulic loading rate, HLR and hydraulic retention time, HRT) as well as the presence of other carbon sources ...
Effect of Isothiazolone on the Performance and Microbial Community Changes in a laboratory Scale Rotating Biological Contactor

Sirikhansaeng, Prapaparn; Laopaiboon, Pattana; Vichitphan, Kanit; Laopaiboon, Lakkana (มหาวิทยาลัยราชภัฏบุรีรัมย์, 2006)

The effect of isothaiazolones, a commercial biocide widely used in paper and pulp industry, on the performance of laboratory-scale rotating biological contactors (RBCs) as well as biocide efficacy was studied. Biofilms ...
-Effects of Sub-lethal Concentrations of Isothiazolone Biocide on the Performance of Rotating Biological Contactors

Sirikhansaeng, Prapaparn; Phukoetphim, Niphaphat; Laopaiboon, Pattana; Laopaiboon, Lakkana (มหาวิทยาลัยราชภัฏบุรีรัมย์, 2021)

The aim of this study was to investigate the effects of operating conditions on chemical oxygen demand (COD) removal and biocide degradation in a synthetic wastewater by rotating biological contactors (RBCs). The RBC ...
Heavy Metal Accumulation and DNA Changes in Plants Around an Electronic Waste Dumpsite Suggested Environmental Management Plan

Tanee, Tawatchai; Chaveerach, Arunrat; Sudmoon, Runglawan; Teanma, Jatuporn; Ragsasilp, Areerat; Sirikhansaeng, Prapaparn (มหาวิทยาลัยราชภัฏบุรีรัมย์, 2018-01-30)

his research studied accumulation of heavy metals in soil and three plant species in E-waste dumpsite in Kalasin Province, Thailand. DNA changes in the plants were accessed by DNA fingerprinting and genomic template stability ...
