Abstract
The present invention relates to systems and methods of wastewater treatment that rely primarily on the use of water treatment chemicals to clean wastewater without the need to use filtration mechanisms. The present invention generally provides a system that is less complex and less expensive to operate than wastewater treatment systems in the prior art.
Claims20
A system for treating wastewater, comprising:
- a first tank;
- a discharge assembly fluidly connected to said first tank, said discharge assembly comprising at least one turbidimeter;
- a valve assembly fluidly connected to said first tank and downstream of said discharge assembly, the valve assembly comprising a first valve and a second valve;
- a first controller electrically connected to the turbidimeter and the first valve for opening and closing the first valve based on a received signal from the turbidimeter;
- a second controller electrically connected to the turbidimeter and the second valve for opening and closing the second valve based on a received signal from the turbidimeter;
- a second tank;
- a plurality of conduits fluidly connecting the second valve of said valve assembly to said second tank and the first valve of said valve assembly to a waste reservoir;
- at least one treatment chemical source;
- and
- a wastewater source;
- wherein when wastewater is added from said wastewater source to said first tank, at least one treatment chemical is added from said at least one treatment chemical source to said wastewater;
- wherein when the turbidimeter senses a desired minimum clarity of the wastewater, the first controller receives a signal to close the first valve and the second controller receives a signal to open the second valve such that the wastewater flows from the first tank to the second tank;
- and
- wherein when the turbidimeter does not sense a desired minimum clarity of the wastewater, the first controller receives a signal to open the first valve and the second controller receives a signal to close the second valve such that the wastewater flows from the first tank to the waste reservoir.

- at least one treatment chemical source;
- and
- a wastewater source;
- wherein when wastewater is added to the first tank from the wastewater source, at least one treatment chemical is added from the at least one treatment chemical source to the wastewater in the first tank;
- wherein when the turbidimeter senses a desired minimum clarity of the wastewater, the at least one controller receives a signal to close the first valve and open the second valve such that the wastewater flows from the first tank to the second tank;
- and
- wherein when the turbidimeter does not sense a desired minimum clarity of the wastewater, the at least one controller receives a signal to open the first valve and close the second valve such that the wastewater flows from the first tank to the waste reservoir.
