Water Quality Analyzer

Water is a vital factor in human life and for the existence of other habitats. Easy access to safe water for drinking, domestic use, food and production is a civic health requirement. Therefore, maintaining a water quality balance is very essential for us. Otherwise, it causes serious health problems to humans. Water contamination has been studied as one of the leading causes of death and illness in the world. Many people die from contaminated water every year. One reason is that public and government ignorance and the absence of water quality checking systems cause severe medical issues.Water contamination is also a serious issue in industries, irrigation and aquaculture.

Traditionally, water quality detection is done manually when water samples are taken and sent to the laboratory, but this process requires a lot of time, cost, and human resources. These techniques do not provide real-time data. By considering these challenges, we have come up with an idea to design a Water quality analyzer to check the quality of the water used for different purposes.

The Process starts from taking the real time data from the water bodies using sensors and type of water need to be checked must be selected from the mobile app. FPGA Board processes the collected data and compares it with the standard data in order to assess the water quality.The quality parameters of the water and the quality of the water will be sent to the mobile app using IoT Technology. If the quality of the water is below the desired levels, an alert will be sent to the user. In this way we can have continuous real time water monitoring.

Project Proposal


1. High-level project introduction and performance expectation

Water Quality Analyzer

Easy access to safe water for drinking, domestic consumption, food and production is a civic health requirement. Therefore, maintaining and knowing water quality is very much essential in the current scenario.

 

Water contamination is observed as one of the leading causes of death and illness in the world.According to the World Health Organization 1 in 3 people do not have access to safe drinking water.Contaminated water can transmit diseases such as diarrhoea, cholera, dysentery, typhoid, and polio.Reports show that “more than 14,000 people” around the world die from water pollution each day. More than 50 lakh people die from contaminated water every year. In many developing nations, contaminated and grimy water is used without proper pre-treatment.

 

In practice, in most of the cases water quality assessment is being done manually by sending water samples to the laboratory, but this process requires a lot of time, cost, and human resources.

 

Hence, it is observed that there is a necessity of a device which can assess the water quality and give a recommendation to the user for its usage. Although, there are few products available in the market which are measuring the parameters of water quality, our proposed idea will process the data regarding the water quality and further based upon our specific requirement (for drinking purpose/ domestic usage etc), it gives recommendations.

 

The proposed device shall measure the following parameters like:

  1. pH value
  2. Turbidity value
  3. TDS value
  4. Dissolved Oxygen level
  5. Hardness of water
  6. Essential ions value

 

Further, the following activity will occur inside the FPGA data processing platform:

  As the parameters of water differs depending upon its usage, first the developed product will seek the input from the user regarding the specific purpose of water usage e.g.,drinking purpose,domestic usage,aquaculture etc.,

Based upon the above input of the user and depending upon the location, the system/algorithm will fetch the standard values of pH, hardness of water, DO levels etc.,

Now, the above values will be compared with the processed data related to the water sample. Based upon the comparison result, recommendations will be given to the user.

 

Implementation plan:

Our plan is to design a prototype for above stated proposal and to test its efficiency by conducting tests at different locations. Further, our recommendations/alerts will be compared with the results obtained from existing laboratory testing practices. If the results correlate to a greater extent, we can extend this work to give real-life solutions.

 

Target users:

  1. Industrial zones/areas
  2. High pollution vulnerable zones
  3. Places where there is acute poverty and less literacy rates etc

The following is the data which shows the relation between the water quality assessing parameters in connection to its usage (as per Indian Standards):

Expected Results:

Based on the selection mode the design is capable of displaying the real time values of the water and warn the user to take further steps, if the water is contaminated.

The design provides continuous monitoring of the water, unlike the traditional way of testing water at laboratories. This reduces the risk of using contaminated water.
