Animal Waste Treatment System

 The purpose of the IET animal-waste treatment system is to clean the flush water from the animal barns by removing suspended solids, bacteria, phosphates and nitrates so that the water can be re-used on a continuing basis to flush the animal barns as well as treating run-off water from a collection system to eliminate ground water contamination.

The system is very straightforward and once installed and optimized, will run with minimal operator intervention.  The system can be designed to handle any size water flow and consists of the following components:

• A black water surge tank to hold flush water from the animal barns.
• A screening system to remove solids and undigested grain.
• An Electrocoagulation (EC) System to coagulate the remaining suspended solids while reducing bacteria and BOD.  The EC System consists of the following:Surge tank.

                                                        System pump.

                                                       Reaction chamber.

                                                       Power supply.

                                                      Development tank.

                                                      PLC control system. 

• A clarifier for separating the coagulated solids from the water.
• A filter to de-water the solids that are removed from the flush water.
• A reactor to remove ammonia and nitrates from the water.
• A recycle tank to hold the treated water for re-use in flushing the animal barns.

The obvious advantages of IET’s animal-waste treatment system are:

• Provide high quality flush water for the barns that will reduce health risks to the animals.
• The system treats the wastewater in a matter of hours rather than the days required for conventional treatment thereby greatly reducing the land requirements for the system.
• The elimination of lagoons that can have a strong odor and are an environmental risk if they breach their banks. 
• Eliminate the need to land apply large quantities of contaminated water that can overload the land with ammonia, phosphates and nitrates.  This water can also potentially contaminate existing ground water sources.
• Being able to re-use the water diminishes the amount of water needed thereby greatly reducing operating costs.
