4. Water project with solar energy
5. We have done projects on the development of a methodology and implementation of a sustainability check of WASH (Water, Sanitation, and Hygiene) interventions.
Water Treatment
Water treatment or water purification is the removal of contaminants from raw water to produce drinking water that is pure enough for human consumption or for industrial use. Substances that are removed during the process include parasites (such as Giardia or Cryptosporidium), bacteria, algae, viruses, fungi, minerals (including toxic metals such as Lead, Copper, etc.), and man-made chemical pollutants. Many contaminants can be dangerous—but depending on the quality standards, others are removed to improve the water's smell, taste, and appearance. A small amount of disinfectant is usually intentionally left in the water at the end of the treatment process to reduce the risk of re-contamination in the distribution system. Many environmental and cost considerations affect the location and design of water purification plants. Groundwater is cheaper to treat, but aquifers usually have limited output and can take thousands of years to recharge. Surface water sources should be carefully monitored for the presence of unusual types or levels of microbial/disease-causing contaminants. The treatment plant itself must be kept secure from vandalism and terrorism. It is not possible to tell whether water is safe to drink just by looking at it. Simple procedures such as boiling or the use of a household charcoal filter are not sufficient for treating water from an unknown source. Even natural spring water - considered safe for all practical purposes in the 1800s - must now be tested before determining what kind of treatment is needed.
Simple water purification or water treatment that you can do at home. If you are getting the water from a well or tap. What you need is a 2-liter bottle like empty clean coke, gravel, sand ( make sure its good sand with no warms in it, etc), activated carbon, and a piece of cloth. Please see below for an example. After this water purification, you should be able to drink it with no problem.
Self Cleaning Water Filter in Stainless Steel
We now deal mostly with self-cleaning water filters in stainless steel. Due to its safety, very easy to maintain, life length ( 10 - 20 years) and gives you very clean water for drinking.
It also shows you how dirty the incoming water is and how clean it has been filtered.
We do recommend that if you want to purify your home or commercial water for drinking you should at least go for a complete set of the water purification system.
That means you need to invest some money for the safety of your staff or loved ones.
A good water purification system has the following steps:
1. Water filter cartridge, with at least 0.5 micron
They are often referred to as sediment or particulate filters and are fine sieves that reduce dirt and other particles. They are used as pre-filters to other treatment systems as well as UV lights. Using them as a pre-filter will often protect a water purifier from damage and extend its life length.
2. Activated carbon, is used to purify liquids and gases in a variety of applications, including municipal drinking water, food and beverage processing, odor removal, industrial pollution control. Activated carbon is produced from carbonaceous source materials, such as coconuts, nutshells, coal, peat, and wood.
3. Ultraviolet water purification is the most effective method for disinfecting bacteria from the water. Ultraviolet (UV) rays penetrate harmful pathogens in your home's water and destroy illness-causing microorganisms by attacking their genetic core (DNA).
Solar Water Purifier
We do recommend solar water purification instead of using electricity. You will save a lot of money by switching to solar energy.
Solar water disinfection, in short SODIS, is a type of portable water purification that uses solar energy to make biologically contaminated (e.g. bacteria, viruses, protozoa, and worms) water safe to drink.
Solar thermal water disinfection uses heat from the sun to heat water to 70–100 °C for period of time.
Solar Reverse Osmosis System
The "reverse-osmosis solar installation" (ROSI) uses membrane filtration to provide a reliable and clean drinking water stream from sources such as brackish groundwater. Solar energy overcomes the usually high-energy operating costs as well as greenhouse emissions of conventional reverse osmosis systems.
Normally used for commercial purposes or industrial use.
