Ozone injection system

摘要: An apparatus for injecting ozone into water includes a riser leg, down leg and plurality of crossovers joining the legs. A partial side stream from main under substantial hydraulic pressure is directed through apparatus. crossover chosen in accordance with head such that flowing therethrough at substantially lower than main. source connected by manifold valving to allow be injected selected crossover. After injection ozone, returned mixing containing remainder pump also alternatively used provide additional where losses cannot overcome diverting
