Abstract
A system and method for filtering caster rinse water. A flocculating agent is added to caster rinse water and the mixture is agitated first at high-speed and then at low-speed to promote flocculation. The flocked solids are removed from the caster rinse water using a filtration unit and the filtered water is stored for reuse.
Claims17
A system for filtering water used in an industrial process, comprising:
- a. a reservoir for containing dirty caster rinse water;
- b a mixing tank in fluid communication with said reservoir;
- c. a supply for flocculating agent;
- d. a first mixer adapted to mix the dirty caster rinse water and flocculating agent in said mixing tank to produce a floc mixture;
- e. a floc tank positioned in fluid communication with said mixing tank and adapted to contain the mixture of the dirty caster rinse water and flocculating agent;
- and
- f. a second mixer adapted to mix the floc mixture;
- and
- g. a filtration unit positioned in fluid communication to said floc tank.

A method for filtering water used in an industrial process, comprising the steps of:
- a. pumping waste water into a tank;
- b. adding flocculating agent to the mixing tank
- c. mixing the waste water and flocculating agent at a first rate of speed;
- d. mixing the waste water and flocculating agent at a second rate of speed less than the first rate of speed, thereby creating a mixture of flocked solids and water;
- e. transferring the mixture of waste water and flocculating agent to a filtration unit;
- and
- f. filtering the flocked solids from the water.
