What Causes Sewage Sludge?
Monday, May 25, 2020
Whether you work in the sewage industry or not you've probably wondered: What even is sewage sludge? Sure, it's disgusting, but what is sludge made up of? Why is it so disgusting?
If you've ever wondered what causes sewage sludge, and how to best treat it, keep reading. We've got the answers you need.

What Is Sewage Sludge?

Sewage sludge is a semi-solid waste material produced by wastewater treatment efforts. When stormwater meets wastewater, the solids and liquids settle and are separated. With this separation comes sewage sludge, a combination of all sorts of hazardous waste material.
Sewage sludge is made up of everything from feces to chemicals, to medical waste and heavy metals from the sewage pipes. It's nothing to scoff at. Messing around with sewage sludge without the proper protective equipment could be deadly for overall health and wellbeing.

What Happens to Sewage Sludge?

Typically, sewage sludge, or biosolids, are dried out and disposed of in a landfill. Sludge can also be further broken down and used in fertilizer. In some cases, it's even used for landscaping purposes.
If this sounds unhealthy, that's because it is. Although treatment plants use various chemicals to remove some of the toxins, these are not 100% effective in removing all present chemicals. When toxic sewage sludge is used in fertilizer, it's like directly injecting the soil with hazardous chemicals.
This, in turn, goes into the crops and the food that we eat. Sometimes it's better not to know, isn't it?
What's worse, sewage sludge can sometimes end up contaminating drinking water. Some sewage plants use what's called leach fields, which dispose of sewage sludge through a series of underground pipes. If these leak, sewage sludge can get into water sources used primarily for drinking water, effectively putting thousands at risk!

What Can Sewage Treatment Plants Do to Reduce Sewage Sludge?

It's impossible to put a stop to sewage sludge entirely. It's a natural side effect that comes with the sewage industry. However, you can monitor it to make sure you're not endangering people when reusing sewage sludge.
An Echosmart sludge blanket monitor is a state-of-the-art sewage sludge monitor. It's installed under the water to analyze the sludge levels of drinking water, wastewater, and industrial clarifiers. It helps sewage workers make sure they're not putting anyone at risk.
If you're in the sewage industry, you should absolutely have a monitor.

Sewage Sludge: More Deadly Than You Think

Sewage sludge is a much more pressing issue than you could ever imagine. It is especially deadly when it leaks into drinking water and the soil around us. It's important to be aware of this issue, and push for cleaner sewage treatment measures when you can.
One way we can reduce toxic sewage sludge is with Entech Design services. Our sludge monitors are top-of-the-line and should be used by every sewage treatment plant. Check out our site to find what you're looking for!
