JIPL’s partner INVENT utilised intense research and over 30 years of experience in the aeration field to develop the iDISC®- Membrane Fine Bubble Diffuser. The innovative concept of the iDISC®- Membrane Diffuser is the combination of sophisticated design and its robust construction resulting in its capability to operate over a wide air flow range whilst achieving high SOTE.
This assists most wastewater treatment plants around the world to reduce their energy consumption, therefore reducing their operating costs.
Design
The iDISC®- Membrane Diffuser design was driven by fluid mechanical and mechanical strength considerations. It consists of a main diffuser body which attaches to the air pipe by a sturdy saddle connection which is secured with a wedge clamp. The flexible membrane sits on a rigid membrane support. This is integrated into the diffuser body and secured by a retaining ring.
The complete iDISC®- Aeration System consists of the INVENT process design, all air distribution piping at the bottom of the tank including connection joints, adjustable pipe saddles, stainless steel anchors, the condensate drainage system, and the iDISC®- Membrane Diffusers. The system is delivered in prefabricated components. This makes the installation in the field safe, easy and fast.
For the Tahuna WWTP upgrade project JIPL supplied new aeration systems for the plant’s three sedimentation tanks. The system is based the i-Disc EPDM Membrane Fine Bubble Diffuser.
The innovative concept of the iDISC® Membrane Diffuser is the combination of sophisticated design and robust construction, resulting in the capability to operate over a wide air flow range.
Invent i-Disc’s modular diffuser system, with bayonet fitting diffuser bodies, quick change aeration media and prefabricated piping elements, provides minimum installation and maintenance downtime, as well as the ultimate flexibility.
Manufactured in Europe to the highest EU standards, the Invent i-Disc 260 diffuser includes three levels of backflow prevention, as well as a flow limiting valve.
The Invent i-Disc 260 Membrane Disc Diffusers are designed for both continuous and intermittent use.
In the Invent fine bubble aeration systems, pressurised air is distributed through pipe work to the diffusers. The grids of pipes with diffusers installed, called an aeration group, cover the whole tank floor and the pipe work is fixed to the basin bottom.
The aeration system was delivered to the Tahuna site as a complete kit and included all necessary accessories for installation. The prefabricated, modular elements (pipes were cut to length) made installation fast and easy.
JIPL also supplied a grit removal system in the form of a coarse bubble system, which they installed along the wall of the tank to provide the appropriate agitation required to remove incoming grit.
