Proposed Technical Approach

The proposed method for H2Oasis water purification.

H2Oasis plans on using a cheap and sustainable method for water purification to provide areas that suffer from natural disasters with clean water. After a natural disaster, water from floods run off into rivers and lakes. The proposed method is based on simple chemistry. Water would be collected from a nearby lake/ water reservoir and left to sit for the stones and dust particles to settle down. The water would go through a three-fold process in a continuous flow system (CSTR) where it would cross a ceramic filter within the tubing to filter out bacteria and would proceed to a chlorine tank that would disinfect the water and kill any viruses and finally, the water will move into a granulated activated carbon tank in which the chlorine, along with any other impurities present will bind to the carbon through adsorption. After this filtering method, the water will be collected in boilers and boiled to rule out any concern for contaminants in the water. The water shall be distributed via trucks to avoid piping manufacturing, installation, and maintenance costs along with the fact that these may be harmed during natural disasters. In order to provide enough water to the community in need, four CSTR systems shall be in continuous use and four boilers shall be used to avoid shutdown in case of any apparatus failure.

2.1 Requirements

General Requirements:

  • Steel Tanks
  • Water Truck
  • Water Boiler
  • Copper Pipe
  • Chlorine
  • Activated Charcoal

Personnel Requirements:

  • Biomedical Engineer: Tests and insures water is safe for consumption and use.
  • Mechanical Engineer: Sets up the water purification systems.
  • Chemical Engineer: Configures the proper chlorine to water ratio as well as activated charcoal needed to filter.
  • Civil Engineer: Sets up the water purification system and connects it to Lago Lucchetti.
  • Truck Driver: Delivers the water via a water truck.

2.2 Architecture Design

This project requires a building to store the water purification systems. This location near Lago Lucchetti, our source, allows for easy access to water. It is also close to the 128 and 373 roads, which make transporting and distributing the clean water easier.

2.3 Implemention Design

When permission is granted, H2Oasis’s Water Purification Systems will be set up in the building in the proposed location. The building will house a total of 12 steel tanks and 4 boilers, 3 tanks and 1 boiler for each system. There are multiple systems to ensure that water is constantly being purified as if one system fails, there are three others to continue providing water. The tanks and boilers are connected via copper pipes and when water is finished purifying, a garage door allows for the water truck to collect the water. Working with the local government, H2Oasis will inform and distribute the water to the public once the systems are complete and pass inspection tests.

2.4 Quality Assurance Test

Our team of engineers will test the systems bi-weekly to ensure they are working properly. The systems will be cleaned out every batch to ensure no contamination and to get rid of sedimentation and dirty activated charcoal. Filters will also be regularly cleaned and replaced as needed. Each batch of water that has gone through our purification system will be tested in the lab and the water’s color, smell, clarity, and taste will be observed before distribution ensure only safe and clean will be given out.
