Eaton Filters Curb Water Consumption, Feed Sustainability
"The systems have been operating perfectly from the day they were installed, ...and the savings from water conservation have been huge.”
The state of California was having a beef with a major meat packing company regarding the amount of water it was using.
Perhaps more so than in any other area of the U.S., water is the lifeblood for social and economic wellbeing in this essentially arid state.
Because of that, numerous legislative initiatives have been implemented over the years to better conserve water covering everything from the installation of more efficient sprinklers, the planting of draught-tolerant landscaping, to the upgrading of some 10 million public and private toilets.
Flushed with the need to do its part to help curb water usage, the meat packing company sought recommendations from Eaton’s Filtration business on how to more efficiently reuse and recycle water at one of its facilities in central California.
Engineers at the company and Eaton representatives eventually identified one area of the processing – known as a hide-on wash station – where water usage was especially high. Recycling the rinse water, they concluded, from the hide-on stations would significantly reduce consumption.
However, recycling the rinse water required an especially robust filtration system due to the extremely harsh operating conditions at a hide-on station, where the filters had to deal with high quantities of dirt, hair, fats and other impurities. High flow rates further complicated the formidable task.
The puzzle was soon solved with the installation of three Eaton DCF-1600 filters with twin pneumatic actuators.
“We were asked to make a recommendation on the conditions we saw during a site visit,” says David Peterson regional sales manager for Eaton. “Based on what I witnessed, no other filter was capable of handling the severe operating environment.”
Ideal for a variety of food applications, Eaton DCF-1600 filters are designed for the rigors of processing highly viscous, abrasive, sticky or otherwise hard to process substances. The filters, which operate at low differential pressure, easily accommodate a wide range of flow and retention requirements.
Additional features include:
- Elimination or reduction of disposable filter bags and cartridges for reduced operator handling, inventory costs and landfill waste.
- Reduction in product loss and more thorough containment purge in a highly concentrated waste stream.
- Reduction or elimination of operator intervention for safer operation.
- Virtually maintenance free with nearly 100 percent uptime.
- Compact design and lower capital cost to fit most installations.
- Stainless steel screens ranging from 15-micron slots to ¼-inch perforations to handle a wide range of filtration needs.
- Available with most popular cleaning discs.
The dual actuators on the DCF-1600 filters isolate the actuation mechanism from the filtrate with a bridged system resulting in a long operating life in just about any challenging condition.
“The systems have been operating perfectly from the day they were installed,” says Peterson, “and the savings from water conservation have been huge.”
Because of the conservation, the company should also be safe if future restrictions develop for incoming water, which have occurred in California in the past due to ongoing water shortages. Meanwhile discharged waste water has been effectively minimized with the reuse of recycled water.
Visitors from sister facilities who have observed the DCF-1600 filters operating in California have been impressed enough to investigate ordering their own installations, adds Peterson.
“Water reuse and recycling in the food processing industry is a recurring challenge,” says Peterson. “Thankfully there are many areas where water can be filtered and reused with the right filtration system, including incoming water from wells, as well as water used in wash stations, cooling towers, storage tank cleaning and more.”
Less disposal of waste water also brings about important benefits to the environment, he notes.
Due to the flood of benefits still occurring today, accolades continue to pour in from all interested parties on the new beefy filters from Eaton.
