What is a Sludge Judge?

Sludge Judge. Measure settled solids in sewage treatment plants, chemical plants, or food processing facilities. Take accurate, noncaustic measurement of settable solids, 5% or less.

What is a Sludge Judge sampler?

The Sludge Judge® is designed to take to take accurate readings of settled solids, 5% or less, in a variety of liquids, to any depth. It is ideal for use anywhere that accurate sample levels of settled solids in noncaustic materials are needed. The unit holds approximatley 89ml per 0.31m.

How to use Sludge Judge sampler?

The sampling device enables you to take accurate readings on settled solids in a variety of liquids, to any depth. Lower the Sludge Judge to the bottom of the tank. When the bottom has been reached and the pipe has filled to the surface level, tug slightly on the rope as the unit is raised.

What is a sludge judge used for?

The Sludge Judge® is designed to take accurate readings of settleable solids, 5% or less, in a variety of liquids, to any depth. It is ideal for sewage treatment plants, chemical plants, and food processing facilities – anywhere that accurate sample levels of settleable solids in noncaustic materials are needed.

How do you read the sludge judge?

How to Use Sludge Judge:

  1. Lower to the bottom of the tank.
  2. Float valve opens, allowing liquid to flow in.
  3. This sets the check valve, trapping the mixture inside.
  4. Read the amount of solids in the sample using the 1′ increments marked on the sections.

How do you sample sludge?

Using a 500 mL glass beaker and a stainless steel trowel, collect the sample from the belt filter press as the sludge falls into the roll-off container. The first grab sample and all remaining grabs should be approximately equal in volume (~ 200 mL). Do not forget to collect any required field duplicates or blanks.

How is sludge measured?

To measure the sludge layer:

  1. Slowly lower the tube into the septic tank until it touches the bottom of the tank.
  2. 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 be measured.

What is a sludge sample?

i. Samples of mud from a rotary drill, or sand from a churn drill, or fine materials from diamond drilling used to obtain information about the formation being drilled.

What is sludge test?

The most common tests for sediment and sludge are total and volatile solids. (ELL) holds HOKLAS accreditation for total and volatile solids, Settled Sludge Volume (SSV) and Sludge Volume Index (SVI) tests, which help to provide accurate figures to engineers in the design of sewage treatment process.

How much sludge is normal in a septic tank?

A septic tank should always be “filled” to its normal liquid level, or the bottom of the outlet pipe which carries effluent to the absorption area. This normal liquid level is usually between 8” to 12” from the top of the tank on average (see picture at right).

How do you make sludge stick?

This procedure determines the thickness of the sludge level (SL).

  1. To make the sludge stick — cut the other 10-foot PVC pipe into two 5-foot sections.
  2. Tightly wrap two feet of a white rag or old towel around the bottom of the stick.
  3. Make hole in scum — do not stain the sludge stick with scum.

How does a sludge judge sampler work?

The bottom piece has a ball valve that allows liquid in when lowered into the sample and seals the sample when raised from the liquid. The middle section connects the top and bottom sections, order additional middle sections to increase the overall length. The top section has a nylon rope that aids in sampling.

What are the costs of clarifier sludge judge?

Various sludge dewatering costs related to operating time, power usage, conditioning chemicals, and dewatered cake dryness for equipment such as belt filter presses, vacuum filters, centrifuges, plate and frame presses, and screw presses.

Do you need a sludge judge for a septic tank?

If $75 to purchase a sludge judge is beyond your budget, you can build a device that will accomplish the same task. You need a long slender stick or pipe of approximately 8’ in length for most applications. If your septic tank is buried deep you will need a longer stick.

Which is the best way to measure sludge depth?

Best operation in terms of effluent clarity is typically attained with as small a sludge inventory (sludge bed) as possible. The sludge depth can be manually measured by such means as using a ‘Sludge Judge”, or automatically by sludge depth meters.
