Case Studies

Protecting PC Pumps in Spanish Biogas Plant

Anaerobic digestion offers an efficient, cost-effective process for green energy development while also providing a sustainable solution for the disposal of animal byproducts. In a typical biogas processing operation, manure, wastewater solids, agricultural residues and food scraps are delivered to a digester system. The process uses microbes to break down the organic material through a fermentation process under controlled conditions, resulting in clean biogas and digested material. That digested material is then used to make fertilizer, compost, soil amendments or animal bedding.

Pump Maintenance Eliminated at Apartment Complex Lift Station

Approaching something the same way repeatedly rarely yields different results. Often, it is the consideration of a different perspective that enables ideal solutions. Such is the case at Villa Mountain Vista North Las Vegas – a 400-unit apartment complex with an onsite lift station equipped with stainless steel-bladed pumps to transport influent. While the pumping of sewage out to the municipal collections system should be fairly standard, frequent pump malfunctions were causes for concern.

Cutting Down on Reweaving of Flushable Wipes

Dealing with tough debris and clogged pumps and pipes are significant and costly issues for many municipal public works departments. These problems are escalating in many places the world over due to the growing popularity of flushable wipes products, as well as aging facilities and a lack of funding for sewer and utility systems. These issues can cost extensive amounts of downtime and capital due to frequent maintenance, equipment repairs and unscheduled shutdowns.

Manhole Helps Keep Trucks Rolling & Sewage Flowing

Regardless of the haul route, commercial drivers across America have come to rely on Pilot Flying J truck stops as a comfortable one-stop respite during the long hours between their destinations. Customers can grab a hot meal, do their laundry, use the business center or even visit an urgent care clinic if needed. Since the merger of Pilot TravelCenters LLC and Flying J Inc.

Down to Size

When the Santa Margarita (Calif.) Water District (SMWD) was formed in 1964 by a group of ranchers who wanted a reliable water source for their cattle, the district served more cows than people. Since then, the area has grown to over 150,000 homes and businesses, and the SMWD maintains more than 1,200 miles of water and sewer lines across a 62,674-acre service area.

Shredding Solids in Scotland

Pump blockages and rags are significant barriers to energy and operational efficiencies at pump stations, causing unscheduled shutdowns, safety hazards for operators, costly equipment repairs and increased power usage due to a decrease in the pumps’ hydraulic performance. Scottish Water observed these negative effects, which were caused by an influx of wipes and rags throughout a network of area pump stations.

A Head Works Hero

Located along the Spokane River and set among large evergreen trees, the City of Coeur D’Alene, Idaho, treatment plant follows some of the toughest treatment requirements in the nation. The facility must meet strict nutrient limits in order to protect the river and a downstream drinking water reservoir.

Surviving the Sludge

The Coeur D’Alene, Idaho, wastewater treatment plant has been in operation since 1939, making it one of the earliest examples of a municipal secondary-level treatment facility in the world. Since then, the facility has been overhauled significantly to keep up with demand, area growth and innovations in wastewater treatment technology.

Nondispersible Wipes Turning Sewers Into Nightmares Nationwide

Increasingly, wipes are causing serious issues for wastewater treatment system operators. Many of the wipes entering sewage systems are not dispersible and technically not flushable. The term “flushable wipes” was spawned in the 1980s when a consumer products company brought a latex-bonded air-laid wet wipe with polyester fibers to the market. The wipe was considered “flushable” since it could transit through the toilet, but with all those polyester fibers, it was not dispersible.

West Lafayette Plant Gets a Grip on Grease Management

Grease can cause big problems, but when managed properly it can provide big dividends as a renewable energy source. The wastewater treatment plant in West Lafayette, Ind., has grease in abundance and is making the most of it.

In 2012, the plant received an average of 18,000 gal of grease per month. Although grease deliveries are not always daily, the plant can get multiple deliveries in one day. One small tanker truck can bring in 2,000 to 3,000 gal while a large truck can bring in between 4,000 to 5,000 gal.

An Abundance of Grease

Fine Screen Prevents Trash from Entering Canadian Wastewater Lagoon

The city of Revelstoke, located along the Columbia River in British Columbia, boasts a growing ski resort and one of the world's best heli-skiing destinations. The scenery of the neighboring Selkirk and Monashee mountains belies Revelstoke's growing population. In 2007, Revelstoke had more than 7,000 residents, and hosted thousands of winter sport enthusiasts at Revelstoke Mountain Resort.

A Growing Problem

Grinder Cuts Maintenance Costs, Protects Pumps in Santa Ana

In recent years, maintenance operators at the Segerstrom Lift Station in Santa Ana, Calif., noticed an escalation in pump ragging and blockages. This led to an increase in maintenance expenses due to half- to full-day cleanings and an increase in man-hours. Engineers sought the help of Costa Mesa-based JWC Environmental (JWCE), which recommended a Channel Monster sewage grinder.

Grinder Saves Time, Energy At Texas Plant

For many years, a water reclamation plant in Texas successfully used six Penn Valley double disc pumps for their primary sludge and scum applications. At their latest expansion project, they added macerators in-line ahead of all the double disc pumps to enhance their process and grind rags and debris. Since the installation of the macerators, they have suffered severe problems with plugging of the pump suction lines that led to frequent pump rebuilds. After years of frustration in dealing with this problem, they turned to the Sludge Monster.

Grinding Down Wet-Well Cleaning & Pump Repair Costs

When Otter Creek Water Reclamation District was faced with expensive recurring cleanup costs at its largest wastewater pump station, engineers solved the problem with the Muffin Monster.

Grinding Down Pump Station Repair Costs

When Otter Creek Water Reclamation District was faced with expensive reoccurring cleanup costs at its largest wastewater pump station, engineers solved the problem with the Muffin Monster, a wastewater solids reduction technology.

Grinders for Grease Reuse

Disposal of fats, oils and grease (FOG) was an ongoing problem for municipalities and utility companies for years.  When these thick, gooey substances are allowed to discharge through drains, they congeal inside sewer pipes and cause an overflow. Sewage overflows are health hazards, damaging property and the environment.

Secret Station

The Suzhou River near Shanghai, China, winds peacefully through beautiful gardens and parks, and flows alongside elegant temples and pagodas. The river has a rich cultural heritage in the region, including several elaborate stone arch bridges that cross it. However, as Shanghai has expanded the river has faced serious challenges from pollution.

Honey Monster Helps Big Fish Environmental Find Clean Water

For several years, local Michigan municipalities were overloaded with septage disposal issues and it was difficult for private pumpers to offload as land-application of septage became illegal. So John Campbell, founder of Big Fish Environmental and a 29-year veteran of septic tank pumping, started developing a unique and efficient septage receiving and treatment plant design.

Vegas Detention Center Proves Monsters are Everywhere

Before the first Muffin Monster grinder was installed, Clark County Detention Center (CCDC) had no effective way of reducing waste in the effluent wastewater being received at the City of Las Vegas Water Pollution Control Facility (WPCF). According to Lloyd Noffsinger, maintenance and operations supervisor for CCDC since 1984, WPCF staff was continually contacting his office to find out how certain items were ending up in their facility. Unfortunately, CCDC needed funding to support any new wastewater projects.

Grinders Cut Costs at Minnesota Treatment Plant

In the beautiful town of Hutchinson, Minn., operators at the wastewater treatment facility have called upon four Monsters in recent years to tame a rising tide of trash and rags in their plant.

In 2005, plant officials tackled a problem area in the influent pump station where twin 20-year-old bar screens were in need of constant maintenance.
