The canning industry has contributed greatly to the worldwide economy from the early 1800's to present. Providing healthy foods to the masses from war times through good times, the canning industry has provided the world with canned vegetables, fruits, juices, soups, meats, fish and pet foods. With great convenience of canned foods has also come tough scrutiny and ever-changing regulations.

Like any product, these changing regulations have overflowed from what goes into the can, to what is done with wastewater after production and canning.

Challenge
Clean Water Technology (CWT) has been called upon by a number of industrial processors and canneries to assist in wastewater treatment.

Provided herein are data from five processors who are facing more stringent disposal requirements and through water conservation efforts, are sending increased contaminant loading to their wastewater systems.

Solution
Aluminum Casting Company: Due to variances in the casting process at two sites owned by this company, CWT evaluated each site independently. The results for each facility showed that treatment via the GEM System provided the reductions below:

Pet Food Processors: Data from two pet food processing and canning facilities are provided herein. With both , the GEM System testing protocol showed exceptional reductions as detailed below:

Economics
SURCHARGES: Utilizing the GEM System to treat these streams, TSS and FOG are expected to reduce current fees and surcharges on all sites shown herein. The GEM System will give you the best possible results by a primary treatment system, saving you money on surcharges or secondary systems.

ENERGY, CHEMICAL, SLUDGE COST REDUCTIONS: Other savings related to the advanced efficiencies of the GEM System included reduced footprint, reduced chemical usage, reduced energy consumption, and reduced sludge-related expenditures when compared to traditional dissolved air flotation (DAF) units.

HAULING: For those sites already using DAF technology, use of the GEM System is expected to provide solids off the beach at approximately 13% reaching a solids value of 20 - 30% after decant. For all sites, this is expected to reduce hauling by a minimum of 60%.
