The degree of this thesis is to create a device to improve wastewater system of the T-35 tank 1. Number 1 for performance, with the purpose to meet the environmental quality management policy, the conservation of water resources. PLC and reduce expenses on water Department C 12 P caused by water that runs off the leaves from the 35 tank T 1. Wastewater system improvements, equipment of tanks T-35 1. No electrical power or engine. Send water out the overflow back into the tank to 35 T 1 40-50 per cent. To reduce costs related to water down
Researchers have designed and built devices to improve wastewater system of tanks T 35 1 and tested updates until you have a device that works perfectly. Then create a questionnaire to evaluate the financial performance The number 5 people, The production of a total of 10 people, 5 people who evaluate the effectiveness of the wastewater system improvements equipment of tanks T-35 1. The researchers made the demo to use equipment and experts to analyze and summarize each. (A) and the standard deviation (SD), with the results to analyze and summarize it average () Is equal to 4.635, which is in favor of criteria strongly and the standard deviation (SD) is equal to 0.326 which does not exceed 1, so that wastewater system improvements of equipment, tanks, T 35 1 the researchers created is determined by the sommutithan and the purpose that set the statistical significant
