“…Cotton pads with a diameter of 140 mm were labeled 1, 2, 3, and 4, soaked in the NO.1~NO.4 test solutions, respectively, and placed in the culture media cultivating different strains; the inhibition zone sizes of the cotton pads were observed to judge the microbial control effects [ 45 ]. The test process is shown in Figure 5 .…”

This study implemented a discharge energy and success-rate monitoring system to replace the traditional oscillograph observation method and conducted a microbial control test for a nanosilver colloid prepared by an Electrical Discharge Machine (EDM). The advantage of this system is that the discharge conditions can be instantly and continuously observed, and the optimized discharge parameter settings can be recorded. The monitoring system can use the arcing rate to control the energy consumption of the electrodes to standardize the nanosilver colloid. The results show that the arcing rate, electrode weight loss, and absorption peak wavelength are very accurate. The nanosilver colloid prepared by EDM is free of any chemical additive, and in comparison to other preparation methods, it is more applicable to biotechnology, even to the human body. The microbial control test for the nanosilver colloid included a Bathroom sample, Penicillium, Aspergillus niger, and Aspergillus flavus. In test solution NO.1 (prepared by micro-EDM), the effects of all four samples were inhibited at 14mm in a metal ring experiment, and in the cotton pad experiment, Penicillium was inhibited at 17 mm. In the metal ring experiment, test solution NO. 2 (prepared by EDM) had an effect at 20 mm on the bathroom samples, but at only 15 mm on flavus. In the cotton pad experiment, the inhibited effect was more effective in Penicillium and Aspergillus Niger; both inhibited effects occurred at 25 mm. Test solutions NO.3 (prepared by micro-EDM) and NO.4 (32 ppm Ag+) had a 14–15 mm effect on all samples in the metal ring experiment. In the cotton pad experiment, NO.3 had an effect on Penicillium at 19 mm while the effect on the others occurred at 14 mm, and NO.4 had an effect at 25 mm in Penicillium and Aspergillus Niger, and only at 14 mm in the bathroom and Aspergillus flavus samples.

“…Currently, nanomaterials are used for wastewater treatment for the removal of contaminates, such as inorganics, organics, and microorganisms. Different types of nanomaterials are used for wastewater treatment, including various metal nanoparticles for degradation of dye-contained wastewater [ 13 ], colloidal solutions of silver nanoparticles used for environmental safety [ 14 ], silver nanocrystals stabilized with Ag + and Ag 0 for treatment of azo-contaminated wastewater [ 15 ]. In addition, Vellaichamy et al [ 16 ] used composites of polyaniline/manganese dioxide/titanium dioxide (PANI/MnO 2 /TiO 2 ) for Cr 6+ reduction from wastewater.…”

The aim of this study was to investigate the use of natural zeolite as support for microbial community formation during wastewater treatment. Scanning electron microscopy (SEM), thermal decomposition and differential thermogravimetric curves (TGA/DGT) techniques were used for the physicochemical and structural characterization of zeolites. The chemical characterization of wastewater was performed before and after treatment, after 30 days of using stationary zeolite as support. The chemical composition of wastewater was evaluated in terms of the products of nitrification/denitrification processes. The greatest ammonium (NH4+) adsorption was obtained for wastewater contaminated with different concentrations of ammonium, nitrate and nitrite. The wastewater quality index (WWQI) was determined to assess the effluent quality and the efficiency of the treatment plant used, showing a maximum of 71% quality improvement, thus suggesting that the treated wastewater could be discharged into aquatic environments. After 30 days, NH4+ demonstrated a high removal efficiency (higher than 98%), while NO3+ and NO2+ had a removal efficiency of 70% and 54%, respectively. The removal efficiency for metals was observed as follows (%): Mn > Cd > Cr > Zn > Fe > Ni > Co > Cu > Ba > Pb > Sr. Analysis of the microbial diversity in the zeolite samples indicated that the bacteria are formed due to the existence of nutrients in wastewater which favor their formation. In addition, the zeolite was characterized by SEM and the results indicated that the zeolite acts as an adsorbent for the pollutants and, moreover, as a support material for microbial community formation under optimal conditions. Comparing the two studied zeolites, NZ1 (particle size 1–3 mm) was found to be more suitable for wastewater treatment. Overall, the natural zeolite demonstrated high potential for pollutant removal and biomass support for bacteria community growth in wastewater treatment.

“…At present, the knitting industries employ the warp knitting and the weft knitting process. There have been many potentials for fabric manufacturing by using the knitting process [7,8]. Knitting has a unique loop structure that makes it possible to use a small number of yarns, change the size of the loops, and make loops that change shape when under tension.…”

Reducing fabric faults in the textile knitting industry is one of the main challenges for knit fabric production. Due to the fabric defects, the sigma level of knit fabric production is between 3 to 3.5. This study aims to increase the sigma level of knit fabric productions. Here, we implement a six sigma strategy in the textile knitting industry. The Six Sigma methodology is applied step by step on the knitting fabric production floor. The DMAIC approach is clearly stated through the phases of defining, measurement, analysis, improvement and control. The types and reasons for different fabric defects are identified by using the cause and effect diagram. The Pareto chart showed that the highest percentages (51%) of defects are related to yarn quality. In the improvement phase, the defects are eliminated by utilizing the Six Sigma methodology. Then, the sigma level of our knit fabric production went to 4. The risk priority number was calculated and suggestions for preventive actions were analysed in the control phase. Implementing the six sigma methodology on the knitting production floor also reduces the cost of production. As a result, this real time study on the knitting production floor has proved to be an economically sustainable production of knit fabric.
