How to select your own water filter ?

How to remove pollutants from rural water ? 

A filter can be used to treat urban as well as rural water. The most common contaminants of rural surface water are impurities released from the fertilizers and pesticides used for unhindered growth of crops and plants . To know how to select a filter which can remove contaminants specific to rural water, a presentation was prepared which can be accessed from here.

How to remove pollutants from urban water ? 

If you use a filter to produce drinking water, it is better to evaluate the source of water and available types of filters before its application.This power point will show the process of selection of a filter configuration for urban water sources....Click here.

How to select the best water filter for your daily use ?

Water filter is solely responsible for maintaining the health of its consumer.There are various types of filters which is developed in combination of different types of purification materials.The type and function of the materials will decide the efficacy and cost of the arrangement.The desired type of efficacy can only be achieved if filter materials are optimally arranged.This presentation shows you how ?

MISO and Oceanic Activities : A multilevel research is going on to establish a link

MISO is the Monsoon Intra-Seasonal Oscillations which represent the extreme events that take place during the month of May to October. "Several times a year from May to October a process called MISO occurs in the atmosphere over the Indian Ocean, the western tropical Pacific Ocean, and surrounding land areas. This weather event brings periods of extremely wet and extremely dry conditions to the area, significantly affecting the people and the economy of those areas. Researchers do not currently know the extent to which the Indian Ocean affects the intensity of this process."

A team of researcher from the US Naval Research Laboratory, University of Notre Dame, and the National Aquatic Research and Resources Agency in Sri Lanka are presently carrying out a research to establish a link between the MISO and the oceanic characteristics.

Älert : ""Fresh water getting saltier

Another tweet highlighting the impact of mining and uncontrolled extraction of natural resources.Tweeted by IISD Water

“I saw a white film on the glass. After trying to scrub it off it turned out to be a thin layer of salt crusting the glass.” Is our fresh water getting saltier? And if so, why? @NewsHour takes a look... https://t.co/9Kn9xi3rOT

The Top three software that you must learn to apply GIS

Recently the Water Resources and hydro power portal published a list of software that you must learn if you want to apply the advantage of GIS and Remote Sensing in your project.

The list was not extensive but selective.

While preparing the list the following factors were given weightage of importance where the first factor was given the highest importance and last one the opposite:

1.Ease of Use
2.Price in INR
3.Support
4.Features
5.Frequency of use in related problems
6.Number of Updates per Year
7.Probability of Bugs

The list can be seen in Baipatra home page.

Research Ideas on Water Reuse

The "Impact of Urbanization on Water Reuse Potential" and "Water Reuse Potential of Hydro-Power plant" can be two of the most important topic of research  related to water reuse.

In the first topic the urbanization impact on Water Reuse Potential(WRP) is estimated.As world wide rapid urbanization is going on, the stress on "available water" of any region is immense.Due to the uneven distribution of water resources the problem is more acute where concentration of population is high but availability of water is low.According to Falkenmark's Water Stress Indicator,a region is said to be water scarce if per capita water availability is less than 5000cubicm.

Again availability of water will imply not only the quantity but also the quality of water available.The water must be qualitatively suitable for consumption.Otherwise, it will not be added to water resources potential of a region.

Due to urbanization there is an immense stress on this "available water".That is why mitigation measures like recycling water is given a lot of importance so that this increased population can be sustained and their demand for water can be somewhat satisfied.

But amount of water available for consumption is constant.Thus the supplied water must be recycled or reused.Hence,the interrelationship between rate of urbanization and WRP will be an interesting aspect to determine.The potential of urban population in degrading the quality of water is also another potential area of research which can enlighten us to determine the amount of water we have and can reclaim for reuse,

The second topic,the potential of water reuse in a hydro power plant will help to install a zero discharge hydro power plant which will be beneficial for both water as well as energy conservation of a region.In the study one objective will be to find the amount of water available for reuse.

Another aspect will be to determine the types of use that can be carried out with the reused water.Actual potential of water reuse can be given by a weighted index of all the purposes of water reuse.Each of the purposes can be weighted with respect to each other following some Multi-Criteria Decision Making approaches.

Once the amount of the water that can be reused for specific purposes are known,it can be multiplied by the weightage of the same purpose and total of the product of weights of all the purposes and available water for that purposes can be used to determine the WRP Index of the hydropower plant.

The index can represent the exact WRP of the plant in terms of the potential of the reused water to mitigate the demand of the plant intself.
