Best Answer

Five photochemical processes work together synergistically to break down or remove contaminants from water. This process actually destroys contaminants, rather than capturing them and creating a hazardous waste disposal problem.

Photocatalytic Oxidation

Previously unobtainable, selected wavelengths of UV light generate unprecedented levels of hydroxyl radicals (OH-) without any chemical additives.

Photocatalytic Reduction

Reduces toxic species such as Mercury (Hg II), silver (Ag I), arsenic (As V, and chromium (Cr VI) to more readily adsorbed materials.

Photolysis

Direct disassociation of contaminants by high intensity UV light, including atrazine, amoxicillin, DEET, and all estrogenic chemicals.

Photoadsorption

The catalyst strongly adsorbs heavy metals including mercury, lead, selenium, and arsenic, permanganate, and other compounds.

Photo DisinfectionMultiple wavelengths and high intensity UV disinfect pathogens more effectively than standard UV germicidal.

The SolarBag uses an effective and simple process for water purification:

  • The bag has backpack and handle straps to allow it to be carried to and from a water source. The Solar Bag is filled from any available water source through the inlet debris filter.
  • Next the bag is placed in the direct sunlight, either lying flat or hanging from a tree or post.
  • For unknown water sources, a food-safe dye can be used as a tracer and timer. When the color has cleared, the water has been purified.
  • Once purified, the SolarBag can be hung for water storage and water can be dispensed by a valve into canteen or pot as required.

How does the reverse osmosis water purification in principle work?

Basically, water is pushed through a membrane, the membrane filters out all of the bacteria and everything else in your water and sends them through a separate tube. The purified water is all that is allowed through.

What is the function of the peripheral protein?

Peripheral membrane proteins are proteins that adhere only temporarily to the biological membrane with which they are associated. These molecules attach to integral membrane proteins, or penetrate the peripheral regions of the lipid bilayer. The regulatory protein subunits of many ion channels and transmembrane receptors, for example, may be defined as peripheral membrane proteins. In contrast to integral membrane proteins, peripheral membrane proteins tend to collect in the water-soluble component, or fraction, of all the proteins extracted during a protein purification procedure. Proteins with GPI anchors are an exception to this rule and can have purification properties similar to those of integral membrane proteins.


Is there a website that can instruct me how to fix the water purification system?

The websites are obviously going to vary due to which kind of water purification system you have, but the easiest way is to watch an instructional, step by step video on how to fix your specific water purification system on www.youtube.com where you can simply type in "how can i fix my water purification system."
