Taskmaster® Shredders Play Critical Role In E-Waste Recycling Operation

A major e-waste recycler which handles massive quantities of electronics received from many states wanted to make improvements. Their installed 4-shaft shredders were causing excessive maintenance expense and downtime. The company processes all types of e-waste from the smallest electronic components, such as flash cards and circuit boards, to the largest, such as mainframe computers – and everything in between. Their process is design to reclaim valuable metals found in the waste components such as silver, gold, and copper which can only be reclaimed after a shredding process.

SPIRALIFT® Screening System- Solves Sludge and BOD Problems at City of Plymouth

The City of Plymouth processes 150,000 gallons of raw sewage a day. Before 2009, the plant had no headworks installed at all. The raw sewage was being dumped into a pond. Because of this, the plant suffered major ongoing sludge and BOD problems. A city engineer recommended a new system be installed to combat these problems. After doing research, the engineer found a Franklin Miller system that proved a perfect solution.

County Drastically Cuts Costs With DIMMINUTOR®

Fairfield Wastewater Treatment Plant in Butler County, Ohio was having a lot of trouble with their grinders. The plant serves over 42,500 domestic customers, a number of commercial and industrial institutions as well as Mercy Hospital of Fairfield. They treat about five million gallons of wastewater collected in over 175 miles of sewer pipe each day.

The brand of grinders they were using was extremely costly to maintain. They had two – one in each of their wet wells. Each year, one of the units would come out for a full rebuild due to the cutters’ complete deterioration. This was costing them about $25,000 a year in rebuild costs.

Taskmaster Aids in Biomass Research

Taskmaster Biomass

At CRBM Marine Biology Research Center in Quebec, Canada, researchers were in search of a grinder for a project involving marine biomass. A big part of this research project was focused on finding and extracting marine molecules that could fight against major diseases such as cancer (breast, lung, prostatic and intestinal). For the research, marine materials such as hard shells, lobster pieces, stretchable fish skin and even large and resistant seaweed needed to be ground to a homogeneous size so the research elements could be effectively extracted from the material. Getting the output size right was imperative to having a workable material for the very delicate extractions and research.

Super Shredder to the Rescue!

Super Shredder Scotts Valley

The City of Scotts Valley sewage treatment plant was having a very tough and frequent problem with their scum pump. This screw pump would rag up monthly, forcing the operators to take it apart and use large wrenches to manually turn the pump to remove the clogged rags and wipes. This was not a sustainable operating model and it was costing the city a lot of time, manpower and money, not to mention causing a lot of frustration.

“We had rakes on the clairifier for scum, rags and other problematic debris,” said Troy Adams, Wastewater Division Manager in the City of Scotts Valley. “But we still had such a massive problem with pump clogging. Rags kept getting into the screw pump.”

When the pumps ragged up and couldn’t turn, taking them apart was a constant issue. “It was an operator nightmare,” Adams said. “It was at least once a week, and at least a four-hour ordeal. It was happening so often, we just left all the tools and everything needed sitting right next to the pump.”

Crusher Provides Cool Solution for Freeze-Dried Mushrooms

When establishing a processing and freeze-drying system for an exotic mushroom customer, Van Drunen Farms in Momence, Illinois found themselves in search of a solution for a unique set of challenges.Van Drunen Farms specializes in processing high-quality ingredients through a multitude of processing methods and services, including freeze-dried, drum-dried, frozen and infused, as well as dietary supplements.The company needed help processing specialty exotic mushrooms. The mushroom spores are grown in wet rice holes. Once grown, the mushrooms are frozen in bulk and sent in forty-pound blocks to Van Drunen for processing. This is where the problem came in.Van Drunen needed a high-quality, reliable crusher that could break the blocks while keeping them frozen. Output size was also a driving factor. Because the pieces would be freeze-dried after processing, the output size couldn’t be too fine. The pieces would have to have an output size between 3/8 and 1/2 inch. The company began exploring options, but had trouble finding a solution that would be able to deliver the right size output, keep the product frozen, and be reliable and well-built.

Screenmaster® CS Bar screen Helps Township Weather the Stormwater

When the township of Little Ferry, New Jersey constructed a new bridge, it created a big problem. The bridge, constructed at a traffic circle in town, created changes to the road that left a drainage pond below the water level of the Hackensack River. The problematic effect this had was immediate as local neighborhoods were flooded on a regular basis.

The town knew they had to fix this problem immediately and decided to install pumps to combat the flooding. Because the runoff was stormwater, the problem was compounded by the large solids such as leaves, branches, sticks and other debris that would enter the pumps and clog or even shut them down.

Maximum Security with The Space-saving SPIRALIFT® SLV

Due to the waste from the Northeast Correctional Facility, Alliance Water Resources, the wastewater treatment plant in Bowling Green, Missouri, was constantly having problems. The prison, which produces 300,000 gallons of water per day, was creating a deluge of problems for the pump station, including clogged and plugged pumps, excessive power draw and the need for continuous service and ultimate pump replacement. The inmates were flushing paper, jumpsuits, and all manner of debris – pretty much anything they could flush. It was costing the plant a lot of downtime and tons of money. Once the pumps started needing total replacements on a very frequent basis, costing the plant more than $30,000 each year, they knew they needed a solution.

The TASKMASTER® TITAN® saves Time and Worries

The Roseland, NJ pump station is one of the largest high-flow stations feeding into the Caldwell Wastewater Treatment Plant. The pump station originally used a trash rack in the channel coming into the station. This arrangement made it necessary for a worker to climb down into the confined space once a day to access and empty the trash rack manually. This was a very time-consuming process and was expensive for the station to keep up with such frequent manual maintenance.
