Fine Bubble VS. Coarse Bubble Diffusers
COARSE BUBBLE DIFFUSERS: PROS

Below, you will find a discussion of the best selling points of coarse bubble diffusers for wastewater treatment systems:

1. High Alpha Factor

The larger holes of coarse bubble diffusers mean the diffusers are less susceptible to fouling than fine bubble diffusers. Bacteria and biosolids are less likely to become trapped and encrusted in the perforations. This keeps the diffusers running efficiently and reduces back-pressure that would otherwise put wear and tear on the blowers.

2. Strong Mixing

The larger bubbles produced by coarse bubble diffusers have more volume, displace more waste liquid, and consequently produce more power for mixing. Biosolids are kept in suspension and are less likely to form unwanted sludge. The effective mixing of coarse bubble diffusers facilitates the breakdown of organic waste thanks to its powerful combination of oxygen, bacteria, and waste material.

3. Low Maintenance

Coarse bubble diffusers’ larger pores mean the diffusers are less prone to clogging and require cleaning less frequently with a pressure washer or manual brush. This low maintenance saves the treatment facility money and time.

4. Durability

Enhanced resistance to fouling means the diffusers wear out and require replacement less frequently. The lessened burden of replacement likewise saves money.


COARSE BUBBLE DIFFUSERS: CONS

Although coarse bubble diffusers offer strong benefits in their power and durability, it’s important for treatment facilities to consider the drawbacks of these diffusers, which are discussed below:

1. Less Efficient Oxygen Transfer

Coarse bubble diffusers produce fewer, larger bubbles that travel faster than those produced by fine bubble diffusers. Larger, faster bubbles transfer less oxygen into the water column. Typically, the SOTE of coarse bubble diffusers is less than 1%. To achieve the oxygen transfer efficiency of a comparable fine bubble diffuser, a coarse bubble diffuser would require twice as much air.

2. Less Efficient Aeration

Similarly, despite their increased vertical mixing power, coarse bubble diffusers disperse less oxygen into the water for less efficient aeration, typically achieving 50% or less of the efficiency achieved with fine bubble diffusers.

Media Retention Screen
The Media Retention Screen, including carbon, allows for the use of larger tanks in plants with higher production tonnage. The media retention screen also reduces downtime incidents and operating costs associated with earlier generations of screen design.


How it Works

Slurry flows through the cylindrical screen and into the annular region between the outer screen surface and the inner cylinder. The screened slurry then flows up through the annular region into the volute and out through the tank laundering to the next tank.

The internal section of the impeller assembly incorporates a down-thrust turbine, which drives the media out of the center section to avoid the concentration of the media and possible degradation. The slurry outlet on the screen matches the face on the tank launder, to which it hooks and forms a tight seal - without the need for fasteners or clamping devices.

The media retention screen can be removed from its tank and a clean one installed in its place in five to ten minutes. By closing the gate in the exit launder for this short time, the need to drop the level in the tank or to take it offline is avoided.

Specific flow rates for the media retention screen can be up to four times greater than other screening methods. Media retention screens are used in CIP and CIL plants worldwide and are quickly gaining a solid reputation as the premier media retention screens for gold recovery.


What Are Sewage Treatment Plants?
Essentially, a sewage treatment plant ;operates by circulating air to encourage the growth of bacteria to break down sewage. The goal is to deliver much cleaner, more environmentally friendly effluent. It involves a similar process to a typical septic tank but has some key differences. Sewage treatment plants, depending on their size, can treat the waste of commercial properties or a number of domestic dwellings.


What Are The Stages of Sewage Treatment?

The general construction of a sewage treatment plant doesn’t differ too drastically from that of a septic tank. Just as with a septic tank, sewage flows from the property being serviced into the first chamber of the sewage treatment plant. Here, the water sits until grease, oil and scum have floated to the top and solids have settled on the bottom of the tank.

Once the process of separation has taken place, the liquid travels into a second chamber which is where sewage treatment plants differ from septic tanks. This chamber is fitted with an air pump that circulates air around the chamber to encourage the growth of aerobic bacteria. This bacteria helps to break down the contaminants in the water, effectively cleaning it.

The final stage of a sewage treatment plant is one last settlement tank. This final tank allows the very last solids that may remain to sink to the bottom of the tank before the effluent is discharged into a soakaway or watercourse.

Once the treatment process has been completed and the wastewater has been treated as thoroughly as possible, it can be discharged into the environment. This is another key area where sewage treatment plants differ from sewage treatment plants. Whereas you must discharge effluent from a septic tank into a soakaway for further treatment in the ground, subject to an Environment Agency Consent to Discharge, you can discharge your effluent into local water sources straight from your treatment plant. This is because of the vastly improved effluent quality that the treatment process produces.
