To us, our name is our expertise and our philosophy, as well as our day to day business. Safe water is the type of water our equipment provides. KWT’s equipment goes beyond the simpler treatment of taste and odor and softening. Our belief is that people have right to not just better tasting water, but water that is also safe and free from contamination put there by others.

SERVICES

KWT water treatment systems concentrate on removing, and reducing, items from the water that are directly responsible for an adverse affect on health. These contaminants include :

• Chemical such as chlorine and pesticides.
• Bacteria, Viruses, and other microorganisms.
• Cysts such as Giardia and Cryptosporidium.
• Heavy metals such as lead and copper.
• Plus specific problems such as sodium, nitrates, etc.
• Hardness, taste and odor, or orange color.

KWT designs and builds systems that cover a wide variety of technologies.

• Adsorption – Carbon filtration is the most widely used adsorption method. Contaminants are soaked up like a sponge onto the matrix of the filter media.
   
• Ion Exchange – Water softeners work on this principle. Hardness Ions (negatively charged) particles are caught on a positively charged bead during the softening process. Sodium is used to clean and “recharge” the bed.
   
• Reverse Osmosis – More correctly referred to as hyperfiltration. Water is forced under pressure through molecules can get through while the rest of the water is rejected by the membrane. Dissolved salt and dissolved nitrates are even too big to pass through.. Other closely related methods of water treatment are ultrafiltration and nanofiltration.
  
• Ultraviolet Sterilization – this is one of the safest methods for treatment to bacteria and viruses, since it works by bombarding organic matter with a special wave length of light, and imparts nothing into the water supply. However, it has no effect no thick shelled organisms such as cysts.
   
• Mechanical Filtration - This is how sediment filters work in removing solid particles from the water. Sediment is rated according to micron size. Sediment filters will remove particles that are larger than the filters micron rating. A 25 micron sediment filter will generally remove most particles larger than 25 microns size. This how red (oxidized) iron removed. Also this is how Cysts such as Giardia and Cryptosporidium are removed since they are not susceptible to oxygen attack.
   
• Oxidation – Excessive amounts of oxygen are inject into the water. There are many type of oxidizing agents in the market. Chlorine is the most common. Chlorine carries suspended oxygen which is released when it encounters certain dissolved matter such as bacteria or iron. The oxygen then attaches itself to the particle. In the case of waterborne bacteria that cannot survive in an oxygen environment, the bacteria dies. In the case of a substance such as dissolved iron, the iron becomes too complex to remain dissolved and it turns from an invisible element to visible particle that can be strained from the water.
