Project Summary

Automation is a need of the era. Today in this present era, automation serves us to preserve time, expense as well as manpower. It is significant to have a smooth and effective system to sustain the vehicle's cleanliness. Our report concentrates on car washer systems and wastewater treatment systems using PLC. Our car washer system has three capital processes namely wash, soaping, and drying, Hence the external and under chases of the car will be washed by detecting the car in the washing bay and further controlled by PLC. This project serves us to detect the car in the washing bay by using the ultrasonic proximity sensor. Sensor plays an essential role in the project. The sensor detects the car size, on this basis the washing arm and under the chases line will function to perform the complete washing. The washing arm completely covers the car in three directions and under the chases line just used for washing the under chases of the car. After the car washed the wastewater will store in an underground tank. This wastewater will be treated on daily basis. The water treatment process involves screening, skimming, settling, and filtration. The wastewater goes through these processes and after that, it will be recycled completely and moved to the fresh water tank. The whole process of washing and wastewater treatment will be controlled through PLC.

Project Objectives

• Real time scale down 360 touchless car wash system using arm washer and under chassis wash mechanism.
• Implementing wastewater treatment plant for car wash wastewater.
• Controlling both above systems simultaneously through PLC.

Project Implementation Method

We are going to make a completely intelligent car washing system with a wastewater treatment plant. In this car wash system, we have an Arm that can complete the washing process of the car. In this Arm, we have installed multiple numbers of nozzles from this nozzles water, and soap is thrown to the car and washes the car from the entire axis. We have installed motors to move the Arm which is controlled by PLC.

Initially, when a car enters the first proximity sensor will sense the presence of a car after that the system will activate. First of all, Arm was activated, and start moving and throwing water to the entire car from top and from right to left as well as start throwing water to the under chassis of the car. When the washing cycle completes the arm will start throwing soap to the car from the top and the entire axis. After that, the Arm will again start throwing water to remove the soap from the entire car. We make a dryer mechanism which can dry the complete car. So in the last step, the Arm starts dryer and dries the entire car.

The car washing wash water is treated by a system that can recycle the wastewater. In the first stage Wastewater is stored in a big tank in which we can store all wastewater we install the level sensor at the top of the tank through which we can check the level of water. Using a Pump we can take water from the main tank and send it to the next tank which is a screening tank that can remove the large particles from wastewater in this tank also level sensor is placed at the top of the tank which can measure the level of water. After that this water is shifted to the next tank which is a skimming tank that can remove oil grease and turbidity from wastewater level sensor are installed at the top of this tank. Then this water is shifted to a settling tank in this tank the wastewater settled for 30 minutes in which all the small particles settle down. After that this water is shifted to the last tank which is the filtration tank in which very small particles like sand and soil are removing so the recycling process is completed. In the end, this recycled water is shifted to the fresh tank and then reuse it for car washing purpose.

Benefits of the Project

• Washing a vehicle through a touchless car wash will save time which is consumed to wash manually.
• As it performs automatic washing of vehicles, so it saves manpower which is used in the washing process.
• Manual car wash consumes more water than automatic, it results to minimize water consumption in car washing.
• As it already uses less water for car washing purposes, this will be treated through a water treatment plant which covers the issue of water consumption as well as water pollution.
• Washing a vehicle by hand (brushes, scrubbing, and sponges) produces small scratches on the vehicle paint.
• It can be implemented in a real-time washing system by just scaling up the system 8 times.
• Less Wear-and-Tear on Vehicles

Technical Details of Final Deliverable

• For the detection of a car in a washing bay proximity sensors are used to detect the presence of a car in the washing bay.
• The arm linear and opposite linear movement will be done through a DC motor, which moves the whole upper box and can wash the car on both sides.
• The car’s front and back will be a wash when the arm moves in the longitudinal direction and the arm’s itself rotational direction.
• Three air fans are fitted on the upper side to dry down the car after washing is complete.
• The water and soap are throwing through nozzles to the car. The water pump is fitted to supply water and soap.
• The different water pump is fitted with different treatment tanks which move the water from one tank to the another.
• The level sensors are fitted in every tank to detect the full and empty tank.
