Aeration Disc Type Fine Bubble Diffuser Wastewater Treatment

DESCRIPTION

SSI’s PTFE membranes can be found In municipal & industrial applications including dairy, pulp & paper, beverage and oil refineries to name a few.SSI's PTFE membranes have been proven since 2004 to improve fouling resistance to such an extent that cleanings are in most cases reduced by a factor of 5 to 10 as compared to standard EPDM membranes from the industry's leading manufacturers.

Material Introduce

How does this benefit standard wastewater treatment plants – bio-fouling and chemical precipitation result in plugging of the holes of the diffuser. As the holes block, the air is being pushed through lesser holes which means the blower is doing more work. Also, air being pushed through lesser holes has higher velocity which reduces bubble contact time and overall oxygen transfer efficiency which means the blower has to provide more air to provide the same amount of oxygen to the wastewater. Due to this property, PTFE membranes maintain “like new” conditions for longer compared to standard membranes. A consultant conducted an independent study on a comparison of standard EPDM membranes with PTFE membranes. The two samples were put in operation in the Aerobic Digesters of the Front Royal WWTP in Virginia, USA. After one year in service, the diffusers were pulled out in September 2010. Here are the images from the visual inspection of the consultant.

ADVANTAGES

1. Single mold technology to reduce costs.
2. Available in 3versions7",9",12".
3. 3/4" M NPT connection.
4. High efficiencies(SOTE) and low-pressure drops tested according to ASCE standards.
5. High resistance environmentally friendly polypropylene body(100℃).
6. Membrane with low plasticizer content to minimize the phenomena of loss of elasticity and shrinkage.

Installation Method

SSI disk aerator can be installed on PVC branch pipe through quick connect saddle, Grommet connection, etc. SSI pre-installed aeration disk, rotate 1/4 turn can be installed on the quick connect saddle, this saddle is suitable for 9" and 12" aeration disk for installation.


Grommet Connection Quick Connect Saddle

Intelligent Upgrade Options

• Patented PTFE membranes prolong the efficiency and reduce whole-life costs.

SSI’s patented PTFE membrane barrier properties not only reduce plasticizer extraction, shrinking, and membrane hardening but also limit dynamic changes that can result from swell, such as creep. Compared with uncoated products that are more susceptible to increases in DWP due to more aggressive fouling and changes in physical properties and weight, the PTFE-coated membrane improves the consistency of DWP (Headloss) values over the product life. This directly impacts long-term power costs and the ability of the system to distribute air uniformly across the tank floor.

• SSI Telemetry – the inside story solves maintenance problems

At the click of a mouse, you will know the DWP of your diffuser membranes, the airflow rate to that monitored diffuser, and the air temperature in the submerged piping system. You can sense vibration, pipe rollover, and water in the grid. Automatic moisture purging and automatic acid dosing systems are available. Through multiple cameras, you can see both inside the grids and surface bubble patterns. Wet probes are also available for DO and WW temperatures. Tracking all this data on a user-friendly online dashboard facilitates communication between consultant and client, manufacturer and rep. This smart technology lets you locate problem areas and allocate resources more efficiently. SSI Telemetry is your preventive maintenance hub in the heart of the plant.
