Today’s wastewater stream is dramatically different than just a decade ago. Yet, many municipal wastewater treatment plants are functioning under older designs and are not optimized for the new reality.
The surge in usage of “flushable” wipes, a relatively recent phenomenon, has been the most significant factor in altering the waste stream. Although marketed as flushable, these products are a growing cause of major blockages because they don’t readily break down. This has also led to an increase in the public perception that all wipes — as well as many other things that were never meant to be flushed — can be discarded in toilets.
As a result, the influx of new material is wreaking havoc on wastewater treatment systems that were only designed to deal with human waste and toilet paper… Read the full article here.
The main purpose of wastewater screening equipment is to remove solid materials from the wastewater system. Solid materials can contaminate waterways, damage equipment, and reduce the overall efficiency of the system, which is why they must be removed at all costs.
In this guide, we’ll cover the different types of wastewater screens available, and give you tips on how to select the right one for your plant.
Types of Wastewater Screens
There are four major types of wastewater screens: rotary drum, in-channel, auger, and static. Let’s take a look at each type, how they’re designed, and what they’re used for.
Rotary Drum Screens
Rotary drum screens are incredibly versatile and offer superior solid recovery from waste streams. At JWC Environmental, we offer internally fed and externally fed drum screens. Internally fed drum screens handle pumped flow and are typically needed when there are higher flow rates. Externally fed drum screens offer 100% overflow protection and are best suited in plants with high oil or grease loadings.
Auger screens are particularly useful for high solid facilities and smaller water treatment plants. JWC offers an Auger Monster, which works off of gravity flow and is the perfect solution for businesses seeking an all-in-one grinder, fine screen, and compactor.
Wastewater screening is the first line of defense during the filtration process. If your design fails to meet industry standards, you may end up damaging and clogging your equipment every week.

How to Select the Right Wastewater Screen
When selecting screens, the first area you should focus on is the wastewater itself. Find out which contaminants are in the wastewater. In many industrial operations, fats, oils, and grease are common. However, you should also consider other contaminants, like salt, surface-active agents, and corrosive matter. If you don’t identify and understand the contaminants in the wastewater, you may experience screen binding/clogging.
The flow rate is also crucial. How fast or slow will the wastewater move through the screen? For best efficiency, make your decision based on the maximum flow rate possible.
Finally, decide how important the byproducts are. Many industrial applications need to screen specific particles out of the effluent to re-use for another purpose. It can be a massive revenue generator for your company. Once you’ve chosen the target size of the particles, you can choose an appropriate screen.

Still have questions? JWC Environmental is here to help! We’ve been a trusted manufacturer of wastewater screening equipment since 1973. Based in the United States, we help clients around the globe, and are known for our innovative solutions.
From its founding in 1973 in Santa Ana, California JWC Environmental had been working with waste treatment operators to solve difficult solids problems in wastewater flows. The two-shafted Muffin Monster® was the answer to the problem and the product has revolutionized how wastewater pumps and other equipment is protected across the United States and the world.
The first patent for the Muffin Monster was granted in 1975 and the technology has continued to improve from there.
