Dewatering Plant Owner Markets His Receiving Station to the Industry

Dewatering Plant Owner Markets His Receiving Station to the Industry
Scott Meyer, right, owner of Screenco Systems and inventor of the Dual Screen System, discusses the features of his receiving station with an attendee at the 2015 WWETT Show. The gravity system dewaters septage, filtering out garbage that collects atop screens and is manually raked into a collection device.

Scott Meyer was stuck. An increase in material volume at his Idaho septage dewatering plant, along with tighter regulations on the cleanliness of land-applied biosolids, left him struggling to keep up. That’s when he took matters into his own hands.

“Our screening system was constantly plugging with hair and rags, and having to stop periodically to clean it meant I couldn’t filter septage at the volume I needed to,” says Meyer. “I started tinkering with my own design, and that’s how Screenco Systems was born.”

Meyer’s high-capacity Dual Screen System, which made its commercial debut at the 2015 Water & Wastewater Equipment, Treatment & Transport (WWETT) Show, is constructed of aluminum with stainless steel screens, with a collection sump and a high-capacity 6-inch drain. The system has two 3/8-inch gapped stainless steel bar screens at opposing angles; the front screen is virtually self-cleaning. It is a non-mechanical, simple way to remove large pieces of trash, rocks and other debris from the flow stream.

“It’s really a simple design with no moving parts,” says Meyer. “When the septage is pumped in, trash and debris hits the deflector and ends up on the bottom of the screen. Once it starts draining slower, the operator manually rakes it clean.”

This unit has a 4-inch telescoping inlet hose that moves laterally and can be connected to a vacuum truck or other flow stream. The system is portable; and the 19.5 square feet of screening area allows for continued use and is easy to rake clean to the garbage drain tray. It can treat over 500 gpm. Various screen gap sizes are available.

The unit can be mounted above an open-pit settling pond or as a stand-alone application that can be stationed almost anywhere. The station is easily cleaned with water; catwalk access enables easy cleaning and raking. The filtered garbage that collects atop the screens can be raked into a wheelbarrow or other collection device. The unit comes with a stainless steel rake.

“We built and tested multiple designs, and have been beta testing this current version in commercial applications for the past 18 months,” says Meyer. “We use it every day at our dewatering plant, and we’ve seen cleaner biosolids, faster off-load times and improved productivity. We’ve run 35,000 gpd through our screen, and the biosolids are virtually garbage-free.”

While he’s been to several past WWETT Shows, the 2015 show was Meyer’s first as an exhibitor. He says his goal was simply to introduce the industry to his product. “We aimed this system at people like me — private contractors who do their own dewatering and small municipalities that dewater as part of their pretreatment,” he says. “I’m hoping to show them that there is a product out there that is simple and affordable. Judging by the positive reaction, a lot of guys have been dealing with the same issues I was.”

Meyer was excited by the response and sold several units while on the floor. He’s already thinking about WWETT 2016 and promises to be back with a “bigger and even better” dual-screen design.

“I have a couple upgrade ideas, including adding forklift skids to make the station more portable,” he says. “The guys I talked with at WWETT told me it was a great design at a good price. Hearing that kind of feedback is exciting!” 208/790-8770; www.screencosystems.com.
