GM foods are classified into one of three generations. First-generation crops have enhanced input traits, such as herbicide tolerance, better insect resistance, and better tolerance to environmental stress.
Types of systems. There are multiple systems by which water treatment systems companies can remove contaminants from water. Point of entry systems: Point of entry water treatment systems are able to treat all of the water entering a home or business and are installed after a water meter or storage tank.
Pulse-powered physical water treatment uses pulsed, electric fields (a technology developed by the food industry for pasteurization) to control scaling, biological growth, and corrosion. This chemical-free approach to water treatment eliminates environmental and health-and-safety issues associated with water treatment chemicals. Pulse-powered systems do not require pumps or chemical tanks. Pulsepowered systems tend to be forgiving of operational upsets and promote cooling tower operation at higher cycles of
