The consumers test resultindicated the most consumer accepted the product at the moderate level and 82% of them were interested in buying at 20 baht per 189 ml glass bottle of the product.

Nowadays increasing water pollution has put significant pressure on water resources. Natural organic matter and organic micro-pollutants have been found in potentially harmful concentrations in numerous water sources. Phthalate plasticizers are also micro-pollutants of concern; Di- (2-Ethylhexyl) phthalate (DEHP) is one of the most frequently observed plasticizers in the environment as well as one of the most persistent. The maximum permissible levels of these compounds in drinking water and wastewater discharged to the environment are set at low concentrations. In this research water samples were collected from the New Bang Kaen Canal in Bangkok Thailand (13°4906.1N 100°3042.4E) which receives wastewater from human activities and contains impurities in the water. Several common treatment technologies currently used to remove inorganic and organic contaminants from natural water supplies address serious environmental problems. Properly selected microfiltration membrane processes are elements of effective systems for water purification. Polymeric membranes are of primary interest for membrane separation techniques because they are both practical and effective. However pretreatment before using a microfiltration membrane is necessary for suspended solids reduction. This research used two types of polymeric membranes namely cellulose acetate membrane (CA) and polyvinylidene difluoride membrane (PVDF) and covers the most applicable requirements regarding pretreatment of the water intake. The performance of polymeric membranes for water treatment was also investigated. The water quality of the New Bang Kaen Canal was assessed in terms of turbidity SS and COD. This research has the potential to contribute to the monitoring of water quality in the New Bang Kaen Canal. Water quality monitoring is a fundamental tool for water resources management. The performance of polymeric microfiltration membranes was effective for water and wastewater purification in terms of solids organic substances and micro-pollutant i.e. DEHP compounds. Nevertheless the further development of polymeric membranes regarding fouling on the membrane surface and within pores needs to be improved to increase membrane performance and ameliorate the limitations of microfiltration polymeric membranes.

The research was to develop environmental packaging from composite materials hyacinth fiber rice husk and coconut fiber for temperature preservation to replace the use of foam packaging that cannot be degraded naturally. In the composite materials water hyacinth fiber rice husk and coconut fiber at the ratios 7: 1: 2 1 : 1 : 2 and 1: 1: 1 were extruded by heat using isocyanate glue as a solder and testing the physical and biological properties of composite materials as fiberboard. For testing of temperature preservation of the bio packaging heat transfer test to obtain the bio-packaging for the environment the composite materials of fiber water hyacinth rice husk and coconut fiber at the ratio of 7 : 1 : 2 was the most appropriate type. Since it had a density of 0.7 grams per cubic centimeter strength of 26.76 MPa moisture content of 3.8 percent ages and swelling of 26.63 percent ages. In dry condition at room temperature it could store heat for 2 hours and could retain the cold temperature as shown for the temperatures rising from 4 to 30.7 degree Celsius within 2 hours. This research therefore presents a new alternative method of natural fiber composite materials application for temperature preservation in order to reduce the use of foam containers and increase cost value to natural bio waste materials.

Bottle of poly propylene (Polypropylene: PP) to replace conventional non-conventional polycarbonate bottles. (Polycarbonate) are used as bottles and water bottles toys household goods which are BPA-contaminated and poly ethylene Terephthalic acid (Polyethylene. Terephthalate) PET water bottles juice bottles. Bottles And bottles and other drugs and chemicals have been canceled. Then turning to the bottle to PP because of the lightweight bottles float on water. Plastic and white The plastic safety can be reused many times (even used) in the UK has the plastic water bottles poly propylene and (Polypropylene: PP) to make water bottles so long but not as popular as bottle caps. open it (lid torn) bottle shape is beautiful with a little input. The process is a extrusion blow but from research using the dryer Injection blow (Stretch Blow) has studied the creation of injection molded preform 19 gram in order to blow a 500 ML size thickness. Preformed from 3.34 mm to 3.46 mm the average measured height of the preform from a mean of 70 mm measured at 69.88 m. m. the oldest of the preform. the average measured 25 mm and 24.96 mm is how a 500 ML size bottle blow molding blow molds percent discrepancy between the form specified. Average Percentage 0.0853 experimental results Blow the preform 19 gram of the injection can be molded into the bottle completely and can not be used as drinking water is due to the equipment used. blown trial Need to study next.

Development of table cloth products from Batik tie-dyed cotton fabric with waterproof finishes aimed 1) to study waterproof finishes process to Batik tie-dyed cotton fabric 2) to test physical properties of Batik tie-dyed cotton fabric and 3) to study satisfaction of consumer to table cloth products from Batik tie-dyed cotton fabric with waterproof finishes. Prototype of table cloth products and questionnaire was used as the tools in this research. The samplings for this study were the 323 consumers from accidental sampling in Faculty of Home Economics Technology and Faculty of Architecture and Design Rajamangala University of Technology Phra Nakhon. Data was analyzed by percentage mean and standard deviation. Reported of physical properties testing of Batik tie-dyed cotton fabric with waterproof finishes as follows; colorfastness to water testing changed in color was grade 4-5 dimensional changes after laundering testing decrease 1.14 percentage in the length and 0.48 percentage in the width colorfastness by hot pressing testing; dry pressing damp pressing and wet pressing changed in color was grade 4-5 and water resistance testing found that surface area having wet patches small. The results from study satisfaction of development of table cloth products from Batik tie-dyed cotton fabric with waterproof finishes were found that; the sample age between 21-30 years bachelor degree education level status of student and monthly income 100001-20000 baht. Consumers purchased and used Batik tie-dyed product categories of clothing agree with table cloth products from Batik tie-dyed cotton fabric with waterproof finishes and selected to buy after this product launch to market from personal preference reason. Color and design price appearance and special properties are the reasons to choose. The total satisfaction to products was highly satisfied (mean 3.65).
