Six types of filters mostly used in purifying water for city dwellers: Issue 1 of HydroGeek Newsletters

HydroGeek Vol 1 Issue 1

Filters are used to purify or convert raw untreated water into drinkable or pure water which can be safely consumed by a human being. After purification, this water has to adhere to the standards proposed by a regulating authority responsible for the said purpose. Every country has its own standards. Generally, different types of filters are used to remove or neutralize five major types of impurities observed in water:  Total and faecal coliform, Biological Oxygen Demand, Hardness, Heavy Metals and Turbidity to achieve those standards. In addition to this, there are other impurities also but if a filter can reduce or neutralize the above five impurities then the filter is allowed to be used as a self-sustainable unit for producing drinking water. The first edition of HydroGeek tries to highlight the role of water filters in creating "sustainable and healthy human life", with the following content :


1) Six types of filters mostly  used in purifying water for city dwellers
2) Five most common contaminants in rural water and how to remove them?
3) How to identify the filter for purifying raw water?
4) Tutorial: Analytical Hierarchy Process
5) Tutorial: Analytical Network Process
6) Smart Use of Water and Energy in Domestic Households
7) Tools: Simple Decision Maker by AHP
8) Recent Jobs in Water Quality Engineering

Five open source free hydrologic models that you can use to model runoff of micro to macro watersheds

The principal objective of hydrologic models is to forecast the runoff of a surface water body specially dendritic systems like rivers,stream etc.. The inputs to these models are generally Rainfall/Precipitation, Soil Characteristics, and other Climatic parameters like evapotranspiration,humidity, etc. LULC and geo-morphology are also used as the required input parameters of the hydrologic models. Both input and output of these models are temporally as well as spatially variable. Now the resolution varies with different models. Some models consider all the sub basins to be a single watershed and determine the output based on the characteristics of this single watershed(lumped).In contrast, some other models will consider the {impact|effect} of each of the sub basins on the central outflow of the watershed(distributed).In a few models, the entire watershed is divided into grids or units of uniform dimension. However, the accuracy is highest for the models, which considers the {impact|ef

Five empirical models, for prediction of peak discharge and estimation of flood

"A flood is an overflow of water on normally dry ground". This is most commonly due to an overflowing river, a dam break, snow-melt, or heavy rainfall. Tsunamis, storm surge, or coastal flooding are some of the examples of common flooding whereas instances of extreme flooding includes the flood  in 1931 at China which killed between 2,000,000 and 4,000,000 people.In 2002, Texas flood which was caused by a reservoir overflow. In just three days, the floodwaters carved canyons measuring 1.4 mile (2.2 kilometres) long and  20-foot-(6 meters)-deep. Floods can be measured for height, peak discharge, area inundated, and volume of flow. Due to the ability of this extreme event to cause disasters, it is important to predict the event well in advance or at the time of designing flood control structures.Flood is a result of a discharge;generally peak discharge;which the drainage network can not hold and eventually overflows and causes inundation.  There are various methods to estimate

How to use the knowledge of hydroinformatics in opening a start up ?

     Hydroinformatics is a branch of informatics which concentrates on the application of information and communications technologies (ICTs) in addressing the increasingly serious problems of the equitable and efficient use of water for many different purposes. Here is a list of the startups which uses the knowledge and techniques of hydro informatics to solve real-life problems related to the management of water resources. Before the list let us introduce the concept of Start-Up : "A startup is a young company founded by one or more entrepreneurs to develop a unique product or service and bring it to market. By its nature, the typical startup tends to be a shoestring operation, with initial funding from the founders or their friends and families." There are various water-based Start-Ups which uses the concept of hydro informatics,i.e., real-time monitoring(RTM), data analysis, Artificial Intelligence( AI) and Machine Learning(ML) and Internet of Things(IoT) to monitor, manag
