This unit takes standard municipal sludge in your aerated digester and thickens it to its maximum potential. Typical results are between 22000 to 25000 Mg/L TSS.
We started with digester sludge in the 8500 TSS range and 1 of our units at our customer’s 1.2 MG/D WWTP.
The customer did not have to haul any sludge for the first 5-7 days.
After the initial thickening period (10-14 days) normal sludge hauling resumed but was reduced by 60%.
This unit runs 24/7, needs only one 110V 20 Amp circuit and has a footprint of about 4 sq./ft.
Total digester volume at this particular location was 400K gal.
Savings in hauling costs alone would allow them to cover the unit cost in less than 20 days.
For press operations or centrifuge separation, doubling the sludge thickness cuts operation time by 50%, makes a better cake or allows you to process more in a single shift.
Here we are removing grease balls built up in an anaerobic digester process from the wastewater at a milk plant. The pilot unit shown is running at approx. 150 GPM, we will use 2 larger units to reach the 400 GPM target.
What are you doing with your Process liquid or Wastewater ?
Did you know that solids in your Process liquid or Wastewater have a direct affect on your discharge quality that can affect your downstream process ?
Sand or grit can clog pipes and a conventional screen.
Solids in your wastewater have a direct link to your BOD & COD.
Removing your solids will improve your treatment system (if you have one) and help to reduce odors.
If you are discharging to the city you may be paying a surcharge based on your BOD & COD these extra charges can become very expensive.
You can also be paying a surcharge based on TSS (Total Suspended Solids) and FOG (Fats, Oils and Grease).
That’s where we come in, by removing these particles (screening anywhere from 15 to 100 micron) and leaving the micro-nutrients, your treatment system will work more efficiently. Fewer solids means less sludge and that adds up to savings. If you are paying the city a surcharge based on your BOD, COD or TSS that surcharge could be reduced or removed altogether.
The cost savings from using our screen system will save you time and money.
We can replace your equipment:
* Bag filter and you never have to buy bags again or open filter housings for maintenance *
* Basket filter and you never have to service it again *
* Sand filter and reduce your liquid loss during backwash by 99% *
* Static screen / Side Hill screen giving you higher flow rates and better screening at a lower micron rating *
* Inline filter and your need for a high pressure pump *
* Screw press and give you a better screening at a lower micron rating *
* Drum filter and reduce the equipment foot print drastically
with our screen system.

Someone once told me for anything to occupy a space you first remove what is there. Even if can't see it or feel it, something is there.
A liquid is applied to the surface of the screen, that liquid is encouraged to go through the screen using our patented technology. All the solids that are larger than the screen openings stay on the surface and are washed away by the next step in our process. The liquid flowing onto the screen never stops not even during the self-cleaning. Screen pore sizes range from 5 microns (um) all the way up to 5000 microns and screens can be made from PP, PE, HDPE, Nylon, SS and many more materials. A 60 micron screen (20"X24") will pass more than 120 gallons a minute (GPM) depending on the percentage of solids in the liquid.
During the second step of the screening process the liquid is blocked from passing through the screen for about 0.25 seconds. This causes the liquid to expand onto the screen surface washing all the collected solids down the screen face toward the collection bin below. The liquid "flow blocking" is stopped and the liquid is allowed through the screen again, all in less than 0.25 seconds. The amount of liquid lost during a self cleaning is normally less than 100 milliliters, any liquid collected in the solids bin can be sent back to be screened again. In most cases the backwash liquid never reaches the bottom of the screen only the solids do. The self-cleaning step can be activated every 5 seconds if needed.
Our system technology can be applied to other types of screen units (Static Screens, Side Hill Screens, Bar Screens etc.) to increase their current flow rate or the same flow rate with a smaller screen opening size.
We also have a yeast termination and disposal process.
