Sustainable Screening: How the MevaScreen RSM Monster Reduces Energy & Maintenance Costs

Now more than ever, wastewater plants must operate with tighter budgets and fewer improvements; reducing energy use and maintenance costs is the only path to continued operation for most of these facilities. If you’re trying to stretch limited funding while maintaining water quality parameters and expected uptime, you need equipment that lasts longer and does more in a single footprint.

That’s where JWC Environmental’s MevaScreen RSM Monster comes in. It’s a complete solution designed to help municipal wastewater plants of all sizes decrease their operational costs. Here’s why the MevaScreen RSM can help you reduce costs:

It Uses Progressive Motion

Unlike other bar screening equipment, the MevaScreen RSM Monster uses progressive motion to minimize the effect of water rush-in, preventing increased wear and capturing a higher rate of solids.

Depending on the installation details, the MevaScreen RSM Monster can achieve debris removal rates of 80% and higher. Choose screening equipment that combines a variety of slot width options to get the combined level of debris removal needed to protect downstream pumps, filters, and bioreactor membranes from fouling and scouring. Everything from large debris to the finest sand grains exits on a waste conveyor, leaving your wastestream ready for further processing.

It Has an Integrated Mechanical Self-Cleaning Feature

With the MevaScreen, there’s no need for additional water usage to rinse the screens clean or for additional mechanical features like rotating brushes that require their own maintenance. The system keeps itself clean and free of most blockages, allowing your team members to focus on other essential tasks.

Self-cleaning screening reduces labor for manual cleaning, prevents clogging that reduces intake capacity, and lowers maintenance costs across the board. Combined with the high screening capture rate, you’ll see less wear and tear throughout your downstream treatment equipment, especially from fine grit and sand.

It Features Patented Pulse Operation

High screening capture rates and self-cleaning features are great on their own, but you’re likely also concerned about the energy required to run new equipment. JWC’s patented pulse operation is integrated into the MevaScreen RSM Monster for this reason.

Your screening equipment will accumulate fewer running hours while providing the same high level of solids removal you need, resulting in savings in both energy costs and mechanical wear-related repairs. Pulsing is easily timed to rising demand or hourly changes, and targeted incoming flows for rapid screening without unnecessary energy use during low-demand periods.

It Has a Unique Covered Design

It’s not just the progressive motion that makes this screening equipment unique—the covered bar design also significantly reduces maintenance needs and prevents blockages that could interrupt the flow. Bar screening equipment with larger slots can easily become clogged with fine debris during the early stages of screening. The MevaScreen’s covered design prevents this by sending the finest particulates to the screens designed to capture them.

Mixed debris size is one of the biggest challenges when screening wastewater. Screens that work well for larger solids tend to clog with fine particles, while finer screens can’t handle being covered with large debris. The varying slot widths, combined with covered lower bars, make the MevaScreen RSM Monster capable of handling mixed streams with minimal maintenance needs, reducing the need for additional screening equipment, freeing up valuable space, and lowering energy costs.

You Can Add Optional Protection for Outdoor Applications

Not all wastewater facilities have enclosed or indoor space for installing new screening equipment. Moving some of your most heavy-duty screening equipment outdoors can boost treatment efficacy without requiring a complete redesign of your facility.

However, not all wastewater screening equipment is designed for outdoor use. One of the biggest benefits of the MevaScreen RSM is that it can be easily outfitted with ice and weather protection for outdoor installations. You don’t need to expand your facility or install new coverage to contain the screening unit. Simply invest in optional upgrades, including our anti-condensation heater, so that temperature differences don’t lead to corrosion inside the equipment.
