Abstract
A high efficiency filter medium is placed in series with a water treatment clarification system for receiving the treated effluent discharged from the clarifier. The treated water is passed through the high-efficiency filter media for reducing the suspended solid constituent of the water to less than 10 ppm. The filter is supported in a open mesh carrier tray and is made of a polyester material adapted for collecting and entrapping the solid suspended particles in the clarified water discharge.
Claims8
A method for removed suspended solids from a liquid carrier, comprising the steps of:
- a. adjusting the pH of a solution to form suspended solids in a liquid carrier;
- b. directing the suspended solid and liquid carrier through a clarifier;
- c. collecting a portion of the suspended solids as sludge and gravity draining the sludge from the clarifier;
- d. collecting a second portion of the suspended solids on collector plates in the clarifier;
- e. allowing the remaining suspended solids in the liquid carrier to flow upward and outward over a dam and exit from the clarifier;
- and
- f. thereafter passing the exited suspended particles in the liquid carrier over and through a filter in series with and downstream of the dam to capture a portion of the remaining suspended solids as the liquid carrier gravity feeds through the filter.
