The Tank Shark provides for a homogeneous mixture within the reservoir, eliminating thermal and residual stratification. Additionally, the Tank Shark allows chlorine and chloramine injection with no moving parts or electrical equipment within the reservoir.
PATENTED EDUCTOR NOZZLE
The Eductor Nozzle puts out a 5 time flow increase to produce a 75-500 GPM upward flow utilizing 50 PSI motive water. This upward flow of water not only provides axial thrust, but also provides a rotational characteristic to the upward flowing stream.
The Tank Shark transfers its applied motive energy to the mass of water in the reservoir, placing it in motion. The nozzle motive energy functions to move colder water from the base of the reservoir up to and on top of the warmer stratified layers. This thermal disruption causes additional mixing beyond the energy associated with the nozzle itself. Chemical Injection occurs in the violent area of the nozzle discharge allowing for complete mixing and distribution of the applied chemical. Additionally, the extreme velocity at the nozzle discharge provides for self cleaning of the injection nozzles.
The upward rotational force of the Tank Shark achieves a homogeneous mixture and eliminates thermal stratification, aged water, ice, and structural damage. The Tank Shark achieves a homogeneous mix within 4 hours.
CHLORINE AND CHLORAMINE INJECTION
If the residual drops below a predetermined set point, chlorine and or ammonia are then injected into the upward flowing stream of water for dilution and mixing within the tank volume. The Tank Shark process is completely compatible with gas chlorine, hypochlorite and onsite generated hypochlorite. When chloramine delivery is a requirement, aqueous ammonia with PSI’s proprietary chiller apparatus is the feedstock of choice.
REAL TIME SAMPLING AND ANALYSIS
A sample line is connected from the Tank Shark to a rotary gear pump located outside of the tank capable of drawing 10 GPH of representative water from the tank. The sample is then driven to a chlorine residual analyzer where a determination of water quality is made on a continuous basis.
DBP formation is significantly slowed by a number of factors including lower water age, lower temperature, no stratification, and aeration or atomization.
