Seneca Ceramic Diffuser

The Seneca Ceramic Diffuser is designed for bubbling ozone gas into water for simple mass transfer of ozone gas into water.

PCD 4 Diffuser:

The PCD 4 diffuser is an excellent choice for ozone/oxygen diffusion because it has superior compatibility with ozone, is able to operate effectively at very low pressure, and has a very wide flow range. The entire unit is composed of ceramic with no components that are oxidized by ozone. Once submerged, it requires only 5 psi in addition to the head pressure to produce a uniform bubble curtain. The low operation pressure is perfect for ozone applications because it eliminates the need for high pressure ozone. Gas flow range is from 0 to 40 Liters/minute. Lower flow rates have a higher Gas Transfer Efficiency. For short water columns (less than 3 feet), or for critical applications where the highest efficiency is needed, it is recommended to keep the gas flow under 10 Liters/minute.

When multiple PCD 4 diffusers are used on one supply line, individual flow control is advised to ensure even distribution to each diffuser.
