Abstract
A chemical mixing method to safely mix a dry chemical into a solution provides a mixing process with high levels of precision and accuracy. Water may be pumped into a mixing tank through a Venturi tube, which creates a vacuum that may be used to withdraw the dry chemical from the shipping container. The eductor system including the Venturi tube may be thoroughly flushed before the mixing process is finalized, and the effluent from the flushing procedure may be pumped to the mixing tank to recover all measured dry chemical and water.
Claims20
A method of mixing a dry chemical with a solvent to form a solution, the method comprising:
- pumping a predetermined amount of solvent into a mixing tank;
- pumping the solvent through a Venturi tube, thereby creating a vacuum in an eductor vacuum line;
- siphoning the dry chemical into the mixing tank using the eductor vacuum line;
- rinsing dry chemical residue from the vacuum line by pumping solvent into a top off/rinse tank containing at least a portion of the vacuum line, the solvent pumped into the top off/rinse tank covering at least a portion of the vacuum line;
- and
- returning an effluent solution from the top off/rinse tank to the mixing tank.
A system to mix a dry chemical with a solvent to form a solution, the system comprising:
- an eductor pump;
- a Venturi tube;
- a vacuum line, the eductor pump pumping the solvent through the Venturi tube, flow of the solvent through the Venturi tube creating a vacuum in the vacuum line of the eductor;
- a mixing tank in which the dry chemical is mixed with the solvent;
- and
- a transfer pump to pump the solvent into the mixing tank and the solution out of the mixing tank.
