Brent, This is the kind of advice I was hoping for with my plea. Can you elaborate on what the purpose is and how the sand trap works? If I understand you correctly, it will capture the solids and hold them in the inlet pit filtering the liquid through. Then, if I understand you correctly, you suggest we use some kind of agitator to keep the solids in suspension allowing them to break up over time? A hand sketch or description would be of great help.
What about heating of the lagoon? Would you preheat at the inlet and then leave the lagoon to do its thing? How do you clean the lagoon? I am assuming if you only allow the FFA in water to get into the lagoon, this will only happen very infrequently... Thanks for the great advice Rex "Suggest you place a sand trap at the inlet and make the pit deep at the inlet. You might want to consider using one of the many methods to disperse the solids if using cow manure. Covered lagoons have proven to be the most cost effective for us. AG Star has a lot of systems they have helped get started.
