  • How LEDs Will Change Water Purification

    Ultraviolet (UV) light has been naturally purifying water for centuries. With clear skies, our sun can inactivate water-based pathogens in six hours minimum. Cloudy skies or unclear water causes imperfect conditions. These conditions allow for bacteria to grow and make natural water sources unsafe to use. Fortunately, we have developed several types of water disinfection, ranging from chemicals ...

  • Why is drinking water treatment necessary?

    Water is found in ample amount almost everywhere on earth. The natural water resources such as lakes, rivers, etc. that provide water contain a lot of pollution, garbage which is unfit for human consumption. To clean the water, it should undergo numerous water treatment media procedures that make it suitable to drink. The water ...

  • Challenges in the implementation of a national programme on drinking water

    Provision of safe drinking water is a challenging problem requiring immediate attention. The skewed distribution of rainfall, inefficient use of water, presence of a variety of contaminants, such as fluoride, arsenic, iron and salinity, in most of the sources, and pollution by various economic activities have been the factors responsible for inadequate resources against the increasing demand due ...

  • Everything You Need to Know About UV Water Purification

    If you draw water from a well or lake and are concerned about its quality, a UV Water purification system might give you the peace of mind your water is safe to use. Households on municipal water systems are not completely safe either, as water main breaks and broken pipes which can lead to water contamination occur frequently. The ultraviolet water purification process uses ultraviolet light or ...

  • Affinity adsorption for the removal of organic micropollutants in drinking water sources; proof of principle

    Sources for drinking water (DW) production contain increasing concentrations of organic micropollutants, such as pesticides and pharmaceuticals. Traditional purification processes are not suitable for their removal or conversion, but even sophisticated technologies, like advanced oxidation processes and membrane filtration, are not able to efficiently remove all compounds from DW. For ...

  • Is It Safe To Drink Tape Water- How do I Know ?

    Well, let’s see what the government is saying about this.  According to the EPA, “Drinking water that meets US EPA’s health-based standards is generally safe. People who are not healthy as a result of illness, age, or weakened immune systems, are more likely to be at risk from certain contaminants that may be found in drinking water. Infants and very young children are also ...


  • Low cost and sustainable surface water purification methods using Moringa seeds and scallop powder followed by bio-sand filtration

    A simple and inexpensive water purification method was developed using natural coagulant (Moringa seed powder) and antibacterial agents (scallop powder) followed by bio-sand filtration. In this study, surface water from different sources (e.g. pond, canal, lake and river) treated with combined Moringa seed powder, and scallop powder (MOSP) at a ratio of 2:1 for 10 minutes ...

  • Evaluation of a silver-ion based purification system for rainwater harvesting at a small-scale community level

    Silver has been known for centuries to be a powerful disinfectant, with no known harmful effects to humans if applied in adequate doses. Although its use was partially discontinued with the advent of chlorination and modern antibiotics, the discovery of bacterial resistance and disinfection by-products has enabled its re-emergence as a viable water purification option. On the other hand, ...

  • City Water International explains The Basics of Water Filtration

    The Basics of Water Filtration Most of us know that filtered water is healthier than tap water because of its purity, but how does water filtration work? The basic principle is that filtered water has passed through a filter which removes contaminants through one of several methods, depending on the type of filter. Most water purification systems work in one of three ways ­ by running water ...

  • Water Reuse Terminology

    All water on Earth is used and reused, over and over, in an elegant water cycle. Water reuse occurs in various ways on a daily basis. It happens when a community’s treated wastewater is discharged into rivers or other water bodies. If you live in a community downstream of another, chances are you are reusing water from an upstream town. Scientifically proven advances in water technology ...
