This research objective is to improve the overall equipment effectiveness of the water filtration systems in the case study of the Water Treatment Plant which divides the water production into 4 production lines. The water filtration system has an electric actuator and gear is the main machine in the water filtration system. An electric actuator and gear have more machine breakdowns. That makes the water filtration system is the bottleneck of the water production process. This research study is divided into two steps: the first step is the presentation of the equation and the steps to measure the Overall Equipment Effectiveness of the water filtration system. The equation used data from the computer maintenance management system to analysis on mean time between failure data (MTBF) mean time to repair data (MTTR) and water production process data. The results can be improved the overall equipment effectiveness of the water filtration system increased to 0.11% 0.68% 0.44% and 2.44% respectively in each production process line. And increased Quantity of Filtration Water increased to 328500 m3/year 1168000 m3/year 1022000 m3/year and 3832500 m3/year respectively in each production process line. In this research used the pillar of focus improvement. By adding a protection system to prevent machine breakdown because of the most of the problems are found that the protection system malfunctions. This is the most problem in the 4th And then used engineering knowledge to improve water production and the success factor are required a human resources of all parties to cooperate brainstorm and analyze the causes of various losses in order to eliminate them.

The objectives of this research were 1) to study the design and experiment of materials for producing water hyacinth basketry templates from para rubber 2) to test the water hyacinth basketry templates from para rubber 3) to create a body of knowledge in the development of water hyacinth basketry templates. from rubber latex to the community The process of operation is to design the shape of a water hyacinth basketry to suit the use of the product first after that create a water hyacinth basketry template from para rubber by experimenting with a formula mixed with natural rubber latex and experiment with weaving vegetables. water hyacinths to find the best techniques and styles Results from research on the design of water hyacinth wicker templates from rubber latex and testing of water hyacinth wicker template designs from rubber latex. The aim is to invent materials to solve the problem of replacing the old wicker template. From the research it was found that the water hyacinth basketry model was made from rubber latex. There are two techniques for creating new templates: removable templates and removable templates. and non-removable templates Removable latex coated wicker template can produce many pieces easy to weave The wicker template part is coated with rubber latex. Non-removable or weave cover It can be used to weave as a furniture product with the properties that were discovered that it has a long service life. It is durable strong and durable. Flexibility to reduce shock during weaving. and can be a tool in the profession Can reduce the cost of producing water hyacinth handicrafts Model development part There is a design template for water hyacinth basketry which is a water hyacinth wicker product that has a shape that is exotic modern beautiful and useful according to the products unique characteristics and is a valuable work that can decorate the house beautifully.

The study of drought factors to analyze and manage water is very important. The main contributing factor to drought is unusual summer weather wind pressure and air mixtures include water vapor and water droplets. In this factors can be analyzed for rainfall in the lower central river basin area and the preliminary data of the research used to analyze drought from Thai Meteorological Department (TMD). This research analyzes the factors that cause drought including rainfall temperature pressure wind and precipitation. The Multiple linear regression analysis used to determine the relationship of factors causing drought. It was found that rainfall had a statistically significant relationship with temperature and pressure. In addition using the Geographic Information System (GIS) an analysis of rainfall in the lower central river basin from October 1920 to September 2021 to found that from August to October there is a lot of heavy rainfall according to the multiple linear regression equation. Therefore the created multiple linear regression equations can be effectively used in the analysis of drought areas in the lower central river basin area.

The dyeing industry both of business size and household size where the remaining water from the dyeing process is dumped into pipes and flows into natural water sources causing sewage problems. Therefore a column type wastewater treatment system has been developed by using a filtration system along with an adsorption system. The materials used to treat the wastewater from dyeing are gravel sand charcoal from wood and activated carbon from coconut shell. The study was conducted on the synthesis activated carbon from coconut shell using for color and molecules adsorption. The amount of activated carbon from coconut shell was varied at 200 400 600 and 800 g applying with filter media and other adsorption materials taking 1 hour to treat the wastewater from dyeing. The parameter using to measure water quality consisted of color value pH suspended solids conductivity turbidity value COD and TKN to indicate the water quality before and after treatment evaluating the efficiency of the wastewater treatment system. The best ratio that can treat the color is the formula containing 800 g of coconut shell activated carbon. It was able to treat the color equal to 5.94 SU or 99.43 percent compared to the wastewater before treatment.

This research aimed to study the causes of changes in water quality and compare the water quality in Khlong Bang Khen Mai when the seasons and sampling points are different. These factors may cause a change in water quality. A total 50 of water samples were collected from 5 sampling points each point approximately 300 meters apart for a total distance of 1.5 kilometers. They cover three seasons such as winter (October 2020 to February 2021) summer (March to May 2021) and rainy (June and July 2021). Three parameters of this research which consist of both the chemical and physical quality parameters are pH Dissolved Oxygen (DO) and Electrical Conductivity (EC). The result shows that the average pH has ranged from 7.10 - 7.74 the dissolved oxygen (DO) was in 1.80 - 2.84 mg/L and the electrical conductivity (EC) was in the range of 327 - 517 μs/cm. A two-way analysis of variance is a statistical method used to compare the water quality in Khlong Bang Khen Mai. The results indicate that the test differences between seasons affected the change in water quality in all parameters with a statistically significant level of 0.05. Afterward the comparison of multiple comparisons by Scheffes method showed that the pH and dissolved oxygen (DO) in the rainy season were significantly different from winter and summer at the level of 0.05. For the electrical conductivity (EC) there was significant differences between summer and winter at the 0.05 level.
