The “Sludge Judge” is used to measure the depth of sludge accumulations in
primary, recirculation, dosing, and STEP tanks.
The proper way to use the Sludge Judge is as follows:
- Slowly lower the tube into the septic tank until it touches the bottom of the tank.
- As the device is slowly pulled out of the water, the check valve closes capturing a
liquid/solid profile of the septic tank water. The thickness of the sludge layer can
Scum Measuring Utility Guage (SMUG)
SMUG stands for “Scum Measuring Utility Gauge.” This tool is used for measuring
scum levels in tanks.
How to use a SMUG:
Select an area, as near the designated measuring locations as possible, that
appears to best represent the average scum depth.
Then, gently push the utility gauge through the surface of the scum blanket until
the gauge penetrates into the clear zone. Special care should be taken to maintain
the structural integrity of the scum blanket while penetrating it. Some scum
blankets will be very firm and crusty, while others will be loose like a soft, light
Once the layer has been penetrated, rotate the utility gauge 90° and slowly raise
it until a slight resistance from the bottom of the scum blanket is felt. With some
practice, one acquires a “feel” for when the utility gauge has come in contact with
the bottom of the scum layer. Usually no more than a 1/4 pound pull should be applied. A slight rise in the surface of
the scum blanket should be noticeable.
Lower the utility gauge slightly, until the surface of the blanket is level again, and read the utility gauge scale directly
to obtain the scum blanket depth. Depths to the nearest 1/4 inch are adequate.
Double-check the measurement by lowering the utility gauge, rotating it 90° or 180°, and repeating the procedure, as
Field Test Kit:
Orenco’s Field Test Kit is a pre-packaged test kit used to quickly gather information
and measure the treatment efficiency of an AdvanTex Treatment System
without the time and expense of laboratory testing. The Field Test kit is ideal for
measuring constituents in wastewater to help maintain steady treatment system
performance by identifying potential issues before they become a problem. It
is not intended for regulatory compliance testing. The Field Test Kit includes
equipment and supplies to test nine important characteristics used to determine
AdvanTex Treatment System health and performance: pH, total alkalinity, ammonia
(NH3-N), nitrate (NO3-N), nitrite (NO2-N), dissolved oxygen, chloride, turbidity, and
This cradle holds the Biotube filter over the tank riser inlet to help simplify the
process of hosing off accumulated debris.
The Cradle is made out of rugged fiberglass, so it is durable and resistant to
breakage. There is also a slotted handle for easy transport and a bolt hole in the
support bracket for securing the cradle to the riser with a lid bolt during cleaning.
In addition, the drain has been threaded to accept a 2-in. threaded fitting and flex
hose — very handy when you’re draining the cradle back into a tank with a pump
vault still in place, or back into a small-diameter tank opening.
