Water Quality Measurement and Treatment System Control

Abstract

The properties of water are directly related to the growth of aquatic organisms. There are physical, chemical, and biological properties that are related. If one of the properties is not suitable, there will affect the aquatic life in the water immediately. May weaken aquatic organisms, get sick easily or be unable to reproduce. Therefore, this research tries to adjust the conditions of the water to be always suitable for the livelihood of aquatic organisms at times. This research is the design and construction of a water quality measuring tool and treatment system control using a turbidity measurement device, the electrical conductivity value and the temperature value. Measurement values can be displayed via a smartphone application. The control system design is working on an automated system. The designed control system has an automated system of working. The results of the system testing showed that the water quality measurement showed the measurement results that matched the measurement. There are two modes of operation: The manual control mode, display on the LCD and the auto mode displayed through an application on a smartphone screen written through the MIT App Inventor program. The measured values of each sensor can be displayed simultaneously on all screens. Another part is the on-off control system. The operation of equipment for water treatment systems relies on electrical disconnection control using solid-state switches. The conditions governing the operation of these devices are obtained by calibrating and comparing the necessary parameters of the water properties and the command system will order the solid-state to work until the water can be adjusted to normal status.
