Reverse Osmosis System Cuts Food Plant’s Eco Footprint

by | Aug 27, 2013

LayneLayne Christensen’s 350-gallon-per-minute reverse osmosis system has reduced the environmental impacts and energy use of a food processing plant’s water treatment system, reports Water & Wastes Digest.

The unnamed large food processing plant is based in Wisconsin and packages green beans, carrots and potatoes. As a means of reducing its energy use and environmental impacts, the plant began looking at alternatives to the softeners it uses to treat boiler makeup water and canning water. The plant approached Layne, its existing feed water provider, to provide a solution.

The resulting reverse osmosis system has reduced all dissolved ions instead of just softening the water, Water & Wastes Digest reports. The new system has also reduced the overall alkalinity by at least 95 percent, allowing the boiler to operate at a lower intensity, saving both energy and boiler chemicals.

Another benefit is the plant’s newly reduced salt consumption. This means reduced chlorides in the plant discharge. Layne’s calculations predict a a 97.7 percent reduction in salt consumption at the plant, amounting to more than 235 tons a year.

Genesis Water Technologies launched a GWT series natural zeolite media filtration system in early August that it says is capable of serving a wide range of applications including drinking water, wastewater effluent, commercial/industrial process water and air pollution applications.

The company says the filtration system can be used in a variety of industry applications including: power industry, beverage industry, oil and gas industry, food processing, industrial/municipal waste water (such as specific heavy metals, process water and wastewater treatment), seawater/surface water reverse osmosis pretreatment, aquaculture and specialty applications including flue gas cleaning.
