I am designing a septage recieving station at a WWTP. It is a small .5mgd wwtp. How much septage should be added to the secondary treatment (A-O)? And how should grease, grit and trash be removed from septage economically. The price of the smallest Lakeside Total Plant with grease removal is $210,000.

Grease removal at septage receiving station

What is the treatment method? Returning sludge to the aeration or contact tank depends on the treatment process. For small treatment plants, I'm guessing an extended aeration process or contact stabilization. The character of the waste will have an effect as well. If it is all domestic, then you have fewer problems to deal with.
Usually grease and oil are allowed to precipitate in a "grease trap"....just a tank where the wastewater is drawn from some point below the surface, as grease floats.

Septage is delivered to a wastewater treatment facility that has been designed to accept and treat this waste along with its normal sewage flow. The septage is usually delivered to a septage receiving station where it is sampled before it is mixed with the sewage flow. The septage sometimes undergoes separate pretreatment before it is mixed with the sewage flow. This varies with the facility design.
Since septage is normally much stronger waste strength than normal domestic wastewater, you must sample prior to adding sample into the wastewater influent.
The septage receiving station is probably going to cost as much as your treatment plant. Here are some design guidelines:
