The Application of Six Sigma for Process Control Analysis in the Malaysian Poultry Wastewater Treatment
No full textIn this paper, the researchers presented the process control analysis of a Poultry Wastewater (PWW) treatment plant that was designed to comply with the Environmental Quality (Industrial Effluent) Regulations, 2009. In this pilot case study, the researchers highlighted the fact that owing to the existing global environmental challenges, a Six Sigma approach needs to be used for developing a new technique that helps in optimising process capability and assesses the treatment reliability. This would allow the effective treatment of different pollutants like pH, BOD5, TSS, COD, O&G and NH3-N before their discharge into the environment. The researchers used several quality control process tools like the I-MR control charts, treatment process capability analysis and treatment reliability assessment in the study. After analysing the data, the researchers concluded that the plant could effectively treat NH3-N, as well as fairly decrease the pH, BOD5, and COD values, whereas it displayed low ability in treating TSS and O&G within the research period. The researchers noted that the process showed low reliability in the treatment of TSS and O&G, i.e., 88.6% and 29.8% respectively, led to the discharge of fine colloids in the effluent. This was attributed to problematic processes in the PWW treatment procedure, such as malfunction of the DAF unit process, ineffective physical-chemical treatment, and tertiary filtration breakdown. The researchers concluded that this PWW plant required additional control and design improvement so that it released a low concentration of toxic compounds in the effluent discharge, and complied with the standards. This research could be used as a reference for additional studies that aimed to improve the quality of the wastewater treatment processes
Promoting sustainable wastewater treatment operations: The role of lean practices and Lean Six Sigma enablers
No full textThis study investigates the influence of Lean Six Sigma enablers (LSS_En), comprising strategy, environment, culture, resource, and linkage based on Sustainable Performance (Sus_Perf) in wastewater treatment plants of Malaysian and Multi-national Companies (MNCs), using data from 276 respondents. Additionally, the study examines the intervening impact of lean practices (LPs), specifically statistical process control, human resource management, and total productive maintenance, on this relationship. Employing partial least squares structural equation modelling, the analysis demonstrates a positive and significant impact of LSS_En on Sus_Perf, withβ = 0.406, p= 0.001 for Malaysian companies, and β = 0.608, p = 0.001 for MNCs. Furthermore, the impact of LSS_En on LPs is also significantly positive in both types of companies, withβ = 0.544, p = 0.001 for locals, and β = 0.546, p = 0.001 for MNCs, respectively. However, the relationship between LPs and Sus_Perf is insignificant in MNCs, withβ = 0.126, p > 0.05, while Malaysian companies show a stronger impact withβ = 0.418, p = 0.001. Multi-group analysis confirms that local companies excel in H3 with a significant difference of 0.289, p = 0.043. However, the intervening role of LPs in H4 shows no significant difference between the two company types in the LSS_En and Sus_Perf relationship when p > 0.05. This research highlights the scarcity of studies exploring the impact of LSS enablers on sustainable performance in Malaysian wastewater treatment plants and emphasizes the role of LPs by focusing on ownership contributions
An explanation of lean six sigma barriers Malaysia wastewater treatment chapter
No full textThis study examines Lean Six Sigma (LSS) implementation challenges in Malaysian
wastewater treatment plants (WWTPs) to enhance the sustainability. LSS, known for waste
reduction through the “reduce, reuse, and recycle” (3R) principles and statistical process
stability, has excelled in manufacturing but faces hurdles in WWTPs. The need arises to
consolidate LSS knowledge and identify key barriers. Findings indicate that “Management
Barriers” (MgtBars) significantly influence “Resource Barriers” (ResBars), “Knowledge
Barriers” (KnwBars), and “Process Barriers” (PrcBars) with a p-value < 0.005. This emphasizes
the urgency for skilled WWTP personnel to adopt LSS, thereby improving compliance and
wastewater treatment service quality
Development of conceptual spin grind dryer design using integrated approach
No full textMinimizing the process of producing a product by considering appropriate design tools in the design process is very vital.
Inappropriate design activities and tools during the development process will escalate the cost and development time of
producing a product. Thus, this paper presents the development of a new conceptual spin grind dryer design using an
integrated approach. Several design activities such as market survey, conceptual selection and concept development were
conducted to develop a new conceptual design of spin grind dryer. Analytical hierarchy process (AHP), techniques for
sequential preference sequence with equal to ideal solution (TOPSIS), and Design for Assembly (DFA) were used to
determine and optimize the proposed new conceptual design. Four different conceptual designs were produced and the
best conceptual design was determined using AHP and TOPSIS. The final design was carried out using DFA and the results
showed that the design efficiency and operation time reduced to 12% and 20% respectively from the old conceptual design.
This result showed the effectiveness of implementing several steps and tools in the development process to produce a high-
quality product in the market
Examining the impact of enablers on green lean six sigma benefits in the Malaysian wastewater treatment sector: a pilot study
No full textManufacturing industries have increasingly recognized the value of Lean Six Sigma (LSS) not only for improving productivity but also for enhancing sustainability. LSS has also gained popularity in the service sector, prompting the exploration of enablers supporting its adoption in environmental services. This study aims to investigate the relationship between Green LSS enablers and operational benefits (OB) in wastewater treatment plants (WWTPs) in Malaysia. The study examines five independent variables (IVs): strategic-based enablers (S), environmental-based enablers (Env), culture-based enablers (C), resource-based enablers (R), and linkage-based enablers (L), in relation to the dependent variable (DV) of OB. Data was collected from 65 certified competent personnel working in WWTPs and analyzed using validity, reliability, factor analysis, and multiple linear regression. The results indicate that the IVs significantly predict OB when the p-value is below the 5% threshold. This suggests that the factors examined have a significant impact on WWTP operational benefits. Furthermore, the R2 value of 0.390 indicates that the model explains 39% of the variance in OB. Specifically, the variables S and C significantly support the hypotheses, while Env, R, and L do not significantly influence OB. These findings provide valuable insights for the wastewater service sector in improving their understanding and implementation of Green LSS to enhance operational performance in a developing country, Malaysia.<br/

POTENTIAL ENERGY CURVES FOR AND
No full textAuthor Institution: Department of Chemistry and Lawrence Berkeley Laboratory, University of California; Lawrence Livermore Laboratory, University of CaliforniaPotential energy curves for the ground state of , the first four states of the positive ion, and the eight excimer states corresponding to the addition a Rydberg electron to these ion cores have been computed using averaged relativistic effective core potentials (AREP) and the self-consistent field approximation for the valence electrons. The calculations were carried out using the LS-coupling scheme with the effects of spin-orbit coupling included in the resulting potential energy curves using an empirical procedure. A comparison of non-relativistic and averaged relativistic EP’s and subsequent molecular calculations indicates that relativistic effects arising from the mass-velocity and Darwin terms are not important for these properties of molecules. Spectroscopic constants for are in good agreement with all electron CI calculations suggesting that the computed values for excimers should be reliable. The lifetimes for the lower states of are computed
