A specific environmental problem of our choosing is Managing Palatable Water Crisis in Disaster Prone Areas

During emergency situation :

• Surface water become turbid and may contain biological contaminants.

• Water become aesthetically unpleasant.

• People want fast, cheap and effective solution.

To fulfill the demand of drinking water in emergency situation, our proposed solution is . . .

PORTABLE NATURAL WATER FILTER

Required Materials :

Plastic bottle Wash cloth/Filter paper Coal/Activated Charcoal

Coarse Aggregate Moringa Seeds Fine Sand

Mechanism :

Cost to make Portable Natural Water Filter:

Total cost to make one Portable Natural Water Filter is Tk 18 to Tk 25 only

Business Rational :

• Immensely useful for people who cannot afford modern filters.

• It can replace or work alongside with costly filtration devices that become useless during emergency situation.

Feasibility :

• Can be carried out in mass production.

• Materials are locally available and cheap.

• Can be set up within a short duration.

Strengths :

• Manufacturers may show immense interest due to the involvement of so little cost to make one unit of this product.• This project does not involve the inclusion of materials that are hard to make or refine.• The idea of portable filter is relatively new in Bangladesh. So, it will gain some interest from experts in the area of water management and purification.• A thought is put in the project to increase the device’s performance for biological contaminants removal. This is done by adding an extra layer of crushed moringa seeds to the filter medium to enhance the process.

Limitations :

• This method of filtration may not remove all waste water parameter.• Some other methods of purification are required if the resulting filtered water from this device is claimed to be 100% safe. Some other methods involve: halogen/chlorine tablet, keeping it in sunlight, boiling and so on.

Outcome :

Impacts :

• Many poor people from rural areas who are affected by natural disaster will have access to clean drinking water as quickly as possible.

• People will suffer less from waterborne diseases.

• It will be able to recover economic water crisis.
