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.

New Separation System Protects New Membrane Bioreactor

With a rapidly growing population and three lagoons nearly at capacity, managers of the Star Sewer and Water District in Star, Idaho, needed to increase their treatment capacity. Additionally, local regulators were encouraging the facility to improve the quality of plant effluent.

The city decided it was time for a major expansion and hired Keller Associates, a consulting engineer firm in nearby Meridian, to explore various technologies. The design team decided to install membrane bioreactors (MBR) as the secondary treatment process.
