  • 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 ...

  • Water Purification Challenges: ZLD, EDI, COP systems

    Applied Water Solutions was contacted by a client who planned to move their manufacturing facility to an area where there is strict limitations on water discharge. Working close with the client we created a process flow diagram (PFD) using multiple water purification technologies that provided pure water generation, water recycling capabilities and offsite disposal of solids. From the PFD we then ...

  • Purification of domestic sewage by water-hyacinth (Eichhornia crassipes)

    Sewage management is posing serious techno-economic problems in cities, particularly in developing countries. A new technology, sewage purification by water-hyacinth (Eichhornia crassipes), is a possible solution. This paper studied the suitability and effectiveness of water-hyacinth in treating domestic sewage. A 28-day experiment was performed under a controlled environment of a screen-house ...
