Description

[0001] An automatic water management based vehicle washing system and method thereof

[0002] Field of the Invention

[0003] This invention relates to an automatic water management based vehicle washing system and method. More particularly, the present invention relates to a system and method for efficiently monitoring the utilisation of water for vehicle washing and discharging water as per the environment and pollution control norms.

[0004] Background of the Invention

[0005] Recently, vehicle washing systems have become essential for all the vehicle manufacturing and vehicle servicing companies due to their abilities to wash vehicles efficiently in lesser time without requiring manual intervention. For the users, it has become more convenient and easier to get their vehicles washed using the vehicle washing system.

[0006] However, the excessive consumption and wastage of water has been a major concern since this automatic vehicle washing technology has arrived in the market. Usually, bike wash and service centres use more than 50 litres of water per bike and let the water run out on the streets, adding to the sludge. This water mixed with hard chemicals for vehicle washing is hazardous for the washer and to the environment. Even the carwash service centres use more than 120-150 litres of water per car and disposing out unregulated and uncontrolled contaminated water which is an extreme kind of water and an overall depletion of the environment.

[0007] In order to maintain a good quality of vehicle washing, the companies or such service centres usually employ fresh water for each set of vehicle washings but this results in huge wastage of water. Therefore, people have also tried recycling used water for re-using it for vehicle washing after treatment to avoid wastage of water but then this does not ensure providing a good consistent washing quality to each vehicle washed any day as the treated water alone to be re-used for vehicle washing may not produce the same washing effect in the next cycles. It has also been seen that after a significant number of vehicle washings, the treated water which were being used repetitively for washing is discarded manually and then fresh water is refilled and employed for washing. This causes unnecessarily a halt in the continuous vehicle washing. Further, the quality of water being discarded is neither regulated nor monitored, therefore not making full use of water for washing till its threshold limit and neither environment friendly procedure.

[0008] It is to be noted that the above known systems and methods have some of the aforementioned drawbacks, because although they solve the problem of washing vehicles to some extent, but they do so at the cost of polluting environment, excessive consumption of water, compromised and inconsistent washing quality, manual intervention and sudden requirement of water replacement causing discontinuity in the washing process, but still not efficient in terms of water saving per wash, environment friendly and consistent wash quality.

[0009] It would be desirable, therefore, to develop an improved system and method for vehicle washing, which is capable of real time automatically managing the water utilisation in terms of quantity and quality of water used or to be used in washing of the vehicles and automatically discharging wastewater as per the environment and pollution control norms, and obviates to the challenges that exist in the prior arts leading to the inefficient washing, wastage of water and depletion of water and environment.

It also shows volume of treated water being used per was, volume of water recycled per wash and volume of freshwater added per wash according to different types of wash. Table 1 :

[0047] However, in one of the embodiment, the discharge of water is not solely dependent on the number of washes as sometimes time and quantity for water discharge can be irrespective of the number of washes because the quality and quantity of water are monitored during and after each of the washes, so whenever it is realised by the cloud server that water to be used is not suitable for next vehicle washing, it immediately instructs via the controller to discharge off a definite fixed amount of water as per the environment pollution control norms and refills the water treatment and recycling system to compensate the amount of water being discharged.

[0048] In accordance with one exemplary embodiment of the present invention, referring to Figure 3, there is disclosed a water treatment and recycling unit (WTRU) for treating and recycling used water from the vehicle wash, wherein the water treatment and recycling unit is operatively designed and placed to integrate it with the vehicle wash along its side length and breadth, thereby enabling the vehicle washing system to serve as a single functional unit for washing of the vehicles.

[0049] The water treatment and recycling unit (WTRU) includes coagulation tank (6), flocculation tank (7), sedimentation tank (8) and Supernatant tank (9), wherein said coagulation tank (6) performs the mixing of inlet water used in vehicle wash with alum and lime by way of auto dosing in the tank (6). The volume of the inlet water is precisely set by the controller so as to enable occurrence of reaction for proper bonding of molecules of dirty water, therefore, maintaining PH and initiating first treatment of Suspended solids, COD, Oil and grease in the coagulation tank.

[0050] Further, the overflow from the coagulation tank is transferred to the flocculation tank (7) for treatment at next level. The flocculation tank (7) makes the bonded molecule of dirty water io and coagulant chemicals heavy to settle down with the help of flocculation chemical. The size of flocculation tank is larger than the coagulant tank and extends backwardly and downwardly and adjacently along the length and breadth of the vehicle wash in the same line as of the coagulant tank, wherein PH is again maintained and second stage of treatment is initiated for treating Suspended solids, COD, Oil & grease in the tank.

[0051] Further, the overflow from the flocculation tank (7) is transferred to the bottom of sedimentation tank (8) which is also extended backwardly and downwardly and adjacently along the length and breadth of the vehicle wash in the same line as of the flocculation tank. The sedimentation tank operates to perform third stage of treatment including treating suspended solids and final treatment of COD, Oil & grease.

[0052] The sedimentation tank (8) is designed to contain an angularly mounted slots (18) which transfers the water collected from the bottom of sedimentation tank (8) to allow water overflow pass through it. The size of sedimentation tank is the largest in the WTRU as compared to other tanks and its mounted slot is designed to be connected at 45-degree angle with another tank called as Supernatant tank (9).

[0053] In one of the embodiments, the under tank (4) of the vehicle wash is made to discharge 20 L of settled sludge out from its below conical shape as and when required and made to pass through the filter (15) which stores the heavy particles and filter out the water to the treated water collection tank (1 ).

[0057] Further, a under tank (4) of the vehicle wash collects water used in washing of the vehicle and transfers the collected water to the WTRU after certain amount of water is made available in the tank which is pre-set by the controller (17). This under tank (4) of the vehicle wash also works as a separator, wherein large particles get separated inside the tank and water is transferred for the next operation in the WTRU.

[0058] The under tank (4) of the vehicle wash (3) is having three sensors which are vertically arranged, namely, bottom sensor configured to stop the recycle input pump (5) upon sensing water level up to a certain height as pre-set by the controller, top sensor configured to stop the wash upon detecting water level equivalent to the vertical height of the tank, hence preventing wastage of water. The under tank (4) of the vehicle wash (3) is also having mid sensor configured to start the transfer of collected water in the under tank (4) of the vehicle wash (3) to the WTRU upon sensing water level at another height higher than the bottom sensor but lower than the top sensor.

[0059] The supernatant tank (9) of the Water Treatment and Recycling Unit (WTRU) is also provided with a lower sensor (L3) for pausing the water recycling by switching off the operation of the output pump (10), and upper sensor (H3) for switching off the recycling input pump (5) and stop the freshwater pump (14) upon detecting the water level at a height of the upper sensor (H3) in the supernatant tank.

[0060] Further, in accordance with just above embodiment of the present invention, wherein said method comprises of verifying and validating the predefined conditions for performing the water discharge operations, wherein the predefined conditions are with regard to the water level in under tank of the vehicle wash (4), treated water collection tank (1 ) and the Supernatant tank (9) and it is only after required level of water verified and validated by the controller in the above tanks, the controller instructs to discharge water out of the treated water collection tank( 1 ).
