Benefits of technology

The system effectively removes particulate matter from dairy wastewater, reducing environmental risks, conserving water, and minimizing odor, while allowing for the reuse of cleaned water, thus addressing the challenges of pollution and water consumption.

Problems solved by technology

As such, this wastewater effluent has an odor and contents which pose a significant environmental risk (bacterial and nutrient load) if left untreated.
An unregulated dairy might merely discharge its wastewater effluent into the environment, thereby causing a major source of pollution to the soil, ground water and / or surface water.
Such an action would not be possible under current federal and state regulations.
All three of these methods would result in both a substantial source of odor, as well as the related environmental concerns.
Further, such systems can use a considerable amount of water, at a significant cost to a dairy.

example 1

[0032]A system for treating dairy wastewater. The dairy wastewater is screened, thereby removing large sized (fibrous) particulate matter. The wastewater is then transitioned through a first sedimentation station whereby sediment is allowed to fall out of suspension and collect on the bottom of the first sedimentation station. After passing through the first sedimentation station, a quantity of reusable wastewater is extracted therefrom and is reused within the industrial process. The water that is not reused is passed through a second sedimentation station whereby additional time is provided for particulate matter to fall out of suspension. From the second sedimentation station, the water passes to a coagulation station whereby a coagulant is added to the wastewater, thereby causing a floc to form containing sediment. Through use of a skimming station, this floc is removed from the wastewater. From the skimming station, the water then passes through a third sedimentation station wh...

[0034]A system for treating dairy wastewater. The dairy wastewater is screened, thereby removing large sized (fibrous) particulate matter. The wastewater is then transitioned through a first sedimentation station whereby sediment is allowed to fall out of suspension and collect on the bottom of the first sedimentation station. The wastewater is then passed through a second sedimentation station whereby additional time is provided for particulate matter to fall out of suspension. From the second sedimentation station, the water passes to a coagulation station whereby a coagulant is added to the wastewater, thereby causing a floc to form containing sediment. Through use of a skimming station, this floc is removed from the wastewater. From the skimming station, the water is discharged into the standard matter, for instance, into a reservoir or applied to crops via irrigation.

Abstract

A system for, and method of, removing particulate material from wastewater discharged from an industrial source.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is a continuation application of application Ser. No. 11 / 747,778, filed 11 May 2007, which was a nonprovisional of Application No. 60 / 747,015, filed 11 May 2006, the disclosures of which are incorporated herein by reference.FIELD OF THE INVENTION[0002]The invention relates to generally to a method / system for removing particulate matter from wastewater discharge from an industrial process, and more particularly relates to a system for purifying dairy barn wastewater.BACKGROUND OF THE INVENTION[0003]A typical dairy has thousands of head of dairy cows. These cows being housed, fed, and milked at the dairy. In such a typical operation, the dairy cows will be held within lots, these lots often having concrete pad portions. The dairy would likewise have a dairy barn / milk room / parlor wherein the twice daily milking of the cows takes place. Such a parlor likewise having a concrete floor.[0004]Diary cows, like any animal, generate...
