JetMix Applications: Blending/Feeding

Blending/Feeding

Blending typically refers to the combination of different flow streams or combining a chemical with the tank contents. In either case, the objective is generation of a uniform regime within the tank so that subsequent process works as desired. These applications are often operated as batching tanks and have a range of liquid level from maximum to empty.

The JetMix system’s efficient mixing pattern provides consistent solids concentration levels under a wide range of operating conditions that is unmatched by other mixing systems. The ability to resuspend settled solids and create a homogenous mass means savings in energy. This allows operating patterns that are not continuous such as single shift, intermittent, or weekend shutdowns. Significant energy savings have been demonstrated along with the low maintenance costs.

BLENDING APPLICATIONS

Many blending applications involve large rectangular tanks such as this in California which was converted to a blending tank for different sludge streams. The powerful jets can be provided with a rotatable gear box to allow them to be aimed at corners or similar difficult spots that are not cleaned by normal mixing patterns.

FEED TO DEWATERING

Uniformity of tank contents is particularly critical for feeding dewatering equipment. JetMix produces an unmatched uniformity regardless of the level in the tank. When this Texas plant began using their JetMix system with a belt press, they found that they obtained a consistent feed from the tank which enabled them to accurately establish a fixed polymer dosage that would be correct for the entire cycle of dewatering the tank contents. Further, they were able to accurately compare different polymers under identical conditions.

CONSISTENT CONCENTRATION SAVES MONEY

Uniformity of a feed stock to subsequent processes means potential savings. The downstream process can be operated more efficiently and more consistently. This eastern metropolis found that the feed from these tanks to a contract dewatering was costing money in terms of penalties. The solids were not consistent which made dewatering more difficult and resulted in back charges to the plant. Further, the supernatant from the dewatering process presented an unexpected load on the plant creating additional operating costs. Converting the tanks to JetMix resulted in a major savings of thousands of dollars in addition to the savings provided by the mixing system energy consumption.

ACCIDENTS WILL HAPPEN!

When chemicals are added to a tank, the mixing system should be operating to assure good distribution. In this Michigan plant, lime was dumped into the tank when the mixing system was shut down. The result was the formation of a pile in the tank. Normally, this would require much time and effort to remove. Fortunately, the mixing system was provided with rotatable nozzles. The positioner station, shown here, allowed the operating staff to aim the nozzles at the pile, breaking it up and distributing the lime throughout the tank. The nozzles were then repositioned for normal mixing. Nobody had to enter the tank or do any physical cleaning.
