Enviro Ceramic Diffuser
The Enviro Ceramic Diffuser (ECD) consists of a high-tech gas diffusion ceramic membrane for efficient micro bubble transmission into water or other suitable liquids. The “200” for e.g., ECD200 refers to the ceramic surface area of 200 cm2 and likewise ECD400 has 400cm2 area of ceramic membrane. We produce two different ceramic membrane varieties, a high pressure (HP) suitable for application under 3.5 bar and a low pressure (LP) diffuser, suitable for under 1 bar gas pressure. When sufficient pressure is applied into the diffuser via the inlet fitting, it takes some time to push the water out of the pores before ultrafine bubbles appear and significant gas flow is achieved. The bubble size distribution is between sub-micron (nano) to about 250 microns (µm) depending on conditions such as salinity, Page 2 of 12 “Resources are limited, Resourcefulness is not” Copyright © Enviro Ceramic Ltd 2026 – All Rights Reserved Rev 4 User Manual ECD Micro Bubble Diffuser REV4.docx pressures, depth, side currents and surface tensions of liquid, gas and solid interface. Our engineered ceramic membrane is made from ultra-fine nano porous aluminium oxide, sintered at high temperature for maximum strength and forming nano sized pores. The membrane is then either encapsulated in tough polyurethane (PU) filled resin or a hydraulic bonded ceramic housing for our ozone diffuser. All diffusers have marine grade 316L stainless steel fittings for the gas connections. The unique patented design we utilise allows an airlift principle to move anaerobic or stagnant water through the centre hole of the diffuser, thereby increasing efficient gas transfer. The novel anti-microbial ceramic we have developed also aids in preventing biofouling of the diffuser.
