Nirma University Chemozale Purify - Design a Water Purifier

“ Water is life's matter and matrix, mother and medium. There is no life without water.” - Albert Szent-Gyorgyi

With two thirds of the earth's surface covered by water and the human body consisting of 75 percent of it, it is evidently clear that water is one of the prime elements responsible for life on earth. Water is life's mater and matrix, mother and medium. A prerequisite for life is pure, healthy water. A major hazard faced by us is the inadequacy of clean water. Hence purification of water has become a necessity. Keeping the above objective in mind, “Purify” aims at designing a wastewater system, which purifies domestic wastewater, based on the conventional filtration system.

Important dates
Statement of Purpose should be submitted latest by 20th February, 2009 to Chemozale. Selected participants will be intimated by 28th February 2009. Final Proposal will have to be submitted by 5th March 2009 to Chemozale. Final competition will be held on 20th March, 2009.
PROBLEM STATEMENT
Design and construct a water treatment unit which removes maximum possible amount of arsenic impurity from the given contaminated water.

Rules & Regulations
TEAM FORMATION
1. Purify is open to all undergraduate and postgraduate students.
2. Team can have maximum of 4 students.
3. No student can be part of more than one team.
4. There is no restriction on the number of teams from the same college.
5. All the participants will be required to submit the abstract for the same.
The event would be conducted in two phases.

PHASE I : Submission of Statement of Purpose
Interested participants will form teams and select a team leader. The team leader should submit the SOP entry through Ideawicket by clicking on the 'Participate' button. You must log into Ideawicket to submit your entry.
The SOP should either be in form of Word Document or PDF, less than 2,00 words, Times New Roman, 12 font size, with 1.5 spacing.

Please mention the following things in the SOP Entry :
1. Name of Participant(s)
2. Contact details of the Team Leader
3. Scanned copy of team leader's Photo ID Card
4. College Name
5. University Name

PHASE II: Final Competition
1. Following this, on the basis of team's preferences and other criteria, the participating teams will be assigned projects. This will be done on a first-cum-fist serve basis. The teams will be provided a link, with a username and password which would provide full information on the project.
2. Participants will then have to make their final submissions of proposal by 10th March, 2009.
3. All the selected teams should be present on time with their machines.
Winners will be funded by National Innovation Foundation for commercialization of their equipment subject to the conditions.

MACHINE SPECIFICATIONS
1. The entire machine must fit into a box of dimensions 40 cm x 40 cm x 40 cm (L x B x H) at all times.
2. No part of the machine can lie outside the box of above mentioned dimension at any point of time.
3. Once the process starts participants will not be allowed to add or remove anything externally. All the necessary arrangements have to be done before commencement of competition.
4. Use of readymade filtering mechanisms like Reverse Osmosis (RO) system isn't allowed.
5. Machine will be thoroughly checked by the organizers of the event. Any team found violating any of the above clauses will be disqualified.
6. Electric supply of 220 V will be provided if required for the process.

SAMPLE SPECIFICATIONS
The arsenic concentration in given wastewater: 50 mg/l at the flow rate 200 ml/min.

EVENT RULES
1. The inlet pipe of 0.5” NPS would supply the arsenic contaminated water at the flow rate 200 ml/min. The necessary arrangement for the distribution of contaminated water if required in respective project would be done by the participating teams only. Organizers will not provide any kind of distribution facility.
2. Contaminated water coming from the source will have a head of 7 ft and will fall under gravity. No positive displacement device will be attached in Inlet line. This has to be kept in mind during designing the project.
3. Once the inlet flow rate starts into the project no tampering or re-arrangement will be allowed.
4. Treated water will be collected from the outlet pipe for 5 minutes once the competition started. This is for judging the efficiency of project. Two samples of collected treated water will be analyzed to determine Arsenic removal efficiency. The % removal efficiency, flow rate of treated water and visual quality of treated water will be the judging criteria.
5. The mounting table will have a circular hole of diameter of 0.5” the middle for 0.5” NPS out let pipe. The participants are advised to make an outlet at the bottom of project so that filtrate can be collected in a container kept below the table simultaneously during the run. Team has to make arrangement in such a way that outlet pipe can be attached to the project.
6. No trial runs will be allowed around the venue of the competition.
7. The teams must adhere to the spirit of healthy competition. The teams must not damage the opponent's project/system in any way. Judges reserve the right to disqualify any team indulged in misbehavior.
8. Any team that is not ready at the specified time will be disqualified from the competition automatically.
9. The project/system would be checked for its safety before the event and would be discarded if found unsafe for the spectators and participants.
10. Violation of any rule can result in rejection.
11. The organizers reserve the right to change/update the rules of the contest at any point of time and will do their best to inform the participants of the same. However, it is ultimately the responsibility of the teams to keep themselves updated.

Judging Criteria

	C1 = Concentration of arsenic in water (mg/l) C2 = Concentration of arsenic in water (mg/l) V = Volume of effluent collected ml X = Color (will be decided by judges) The decision of the judges shall be final and binding.
