Inline Ozonation Systems

Inline systems inject ozone directly inte main process flowgh a venturi injector or diffuser, often combined a static mixer to improwise mass transfer. These systems are compact and require no additional tankage, making them ideal for plants where space is at a premiume.

Inline systems are mecht effective when he water im relatively clean, with low ozone e.d d d low turbidity. They are common ly use for destination tion of groundwater or filtered water. The primary limitation is that contact time is fixed by pipe geometry, so changes in flow rate alter the CT value. Facilities with highly variable flowe may need flow- paced dosing controls or a holding tank to maintain consistent perforce.

Dedicated Ozone Contact Tanks

For plants with designant space, dedicated contact tanks provide thee highess level of process control. These tanks are designat to optimize mass transfer and contact acct time, typically using fine- bubbble diffusers at te e bottom of a deep basin.
