A vacuum pump is a device that removes / sucks gas (in this case water) molecules from a sealed volume in order to leave behind a partial vacuum.

Reverse Osmosis (RO) filter is a water filter that removes contaminants from water by using pressure to force water molecules through a semipermeable membrane. During this process, the contaminants are filtered out and flushed away, leaving clean, delicious drinking water.

A garbage containment unit is placed at the bottom of the bottle which helps store the garbage/wastes, when the water gets purified. This can be removed later.

Gyroscope is a device consisting of a wheel or disc mounted so that it can spin rapidly about an axis which is itself free to alter in direction. The orientation of the axis is not affected by tilting of the mounting, so gyroscopes can be used to provide stability or maintain a reference direction in navigation systems, automatic pilots, and stabilizers.

The Arduino Uno R3  a microcontroller board based on the ATmega328. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started.

A relay is an electrically operated switch of mains voltage.It means that it can be turned on or off, letting the current to go through or not. Controlling a relay with the Arduino is as simple as controlling an output such as an LED.

The floater helps the puri pod to float on any given water body it is placed in.

Puri pods basically stands for purification pods as these machines purify water and also are capsule or pod like shaped. These machines float on the surface of water due to the air-filled cavities (floaters) present in them and suck water in using a vacuum pump powered by a solar pump (as developed in the future prototype).

Note: that the vacuum pump does not suck water at a high rate, it sucks it at such a rate that the water entering does not disturbs the aquatic life’s equilibrium.

The vacuum pump is connected to one of the terminals of the relay, which is further connected to the Arduino microcontroller. The Arduino is then controlled through a software coding program. The other terminal of the relay is connected to the power supply.

Hence, as we move forward the vacuum pump sucks water into the Puri pod and causes the water to pass through reverse osmosis filter.

Note: These filters are determined by the nature of stagnant water bodies i.e. the minimum and the maximum size of garbage content that can be found there.

Due to passing of the water through these filters the water gets purified and hence, we get clean water. The impurities that are found in the water are stored in the garbage chamber which is placed at the bottom of the bottle.This garbage is removed and further properly treated in a plant.

In this project, the main power consumers is the vacuum pump that is used to suck water in and suck garbage out. Moreover, the power consumption of these would not exceed the power generated by the solar panel placed at the top of the Puri pods but there would be production of extra energy that can be harvested from these machines if we use a properly insulated water proof cable. In the real cases, this project would also be used along with a gyroscope which would be used for balancing this pod when it is deployed in a harsh case scenarios such as when this project is implemented in the case of oceans.

Working model (For Demonstration) :

Puri Pods is basically a simple modification of the principle used in the case of vacuum cleaners. Vacuum cleaner consists of 3 parts – suction, filtering and output which is very similar to what we have proposed. Moreover, the...
