Introduction

Brackish water is fresh water that contains high quantity of salt, but not as much salt as in sea water. Brackish water can contain anywhere from 0.5 grams to 30 grams of salt per litre of water whereas fresh water contains less than 0.5 grams of salt per litre of water. This water can often be found where seawater and fresh water mix, for example an estuary or they can occur in brackish fossil aquifers .Many underwater forms can survive brackish water, but it can be harmful to its surroundings. Because of its high salt content this water cannot be used for irrigation purposes or for human or animal consumption. Desalination is the process used to remove the salt from brackish water so that it can be used for irrigation and domestic purposes.

Problem Statement

The Cheyenne River Sioux Tribe has several wells that contain brackish water. This water will be used as a water source for the local livestock, but as we know the brackish water they are using is not suitable for animal consumption as well as irrigational purposes, a small scale desalination system needs to be identified that strikes balance between efficiency and economy and designed to produce water of low salt content suitable for regular purposes.

The participants need to come up with a desalination system to desalinate 300ml sample of 3% by weight of sodium chloride solution (with water as solvent).

Event Specifications

It is necessary for the teams to submit an abstract via email at " kaushik.suggu@gmail.com " about their model before the competition as this could enable us to provide required material and also to notify teams about any illegal components in their models.

The written abstract should be prepared on the following lines:

The mechanism and the basic layout of the model, explained in detail, along with the proper diagrams if possible.
Description of any new /innovative or advantageous mechanism used should be explained completely
A brief description of environmental concerns and possible solutions and a solution to discard brine solution to the nature should be included in the abstract. However it is not required to treat the concentrated brine solution obtained in the process of desalination.
Each team is allowed to make one submission only. In case of multiple submissions, the first one will only be used for judging purposes.
The specifications of all components used.

Model Specifications

Use of readymade filtering mechanisms and commercially available desalination equipments are not allowed. (Membranes are allowed. In case of using membranes, please mention before hand to the event managers about the type of membranes being used.)
The participants are not allowed to remove or add anything externally once the process starts.
The system will be thoroughly checked before the event. The team violating any of the above specifications will be disqualified.
Participants will be a given a 220V electric supply if required for the system designed.

Rules

General

A team can have a maximum of 4 participants.
A student can represent only one team and cannot be a part of more than one team.
Any number of teams can participate from the same college.

Event rules

The maximum dimensions of the model should be 2 metres in length and no limitations on the diameter.
Use of readymade models is strictly prohibited (membranes can be used).
All the teams will be given a trial run before the actual event. They are allowed to do any modifications as per the results of trial run after the consent of the event managers.
Any team that is not ready at the time specified will be disqualified from the event.
All the teams must adhere to the spirit of healthy competition.
Event managers reserve the right to change/update any or all of the above rules as they deem fit at any point of time. If any will be highlighted on the website and notified to the registered participants. However, it is ultimately the responsibility of the teams to keep themselves updated.

Judging Criterion

Judgement will primarily be based on

Power consumption.
Time taken for the process.
Concentration and the amount of the desalinated sample.
Economy of the design.
Improvisation of an existing technique will be given more credit.

Other judgement criterion will be

The brief description about the environmental concerns and their possible solutions (from the abstract).
Spin offs will also be given the credit.

Certification Policy

The top three Participants will be awarded merit certificate and cash prize. The amount will be soon uploaded.
All the participants will be given a participation certificate.
