Actually any number of things..
1. Drain the sludge into an open container, allow excess water to continue to drain via a small drain (ie.. oil pan), then you can dispose of the solid matter in the back yard etc..
2. I personally find that most of the materials are quite benign, and make an excellent fertilizer.. especially where I am having problems growing grass (I am terra-forming my back 23 acres... ) so I use it along side the road or in areas that are lacking vegetation.
3. The liquid itself (although by using TSP - you only need to drain the sludge occassionally, the fluid can remain) if you must drain the tank can be safely applied to your lawn etc. as a fertilizer. Just don't drain it anywhere near your trout or Koi pond...
Disposing of it in this manner may have some tree huggers up in arms, but true environmentalists understand that phosphates are naturally occuring.. and do not present any danger to the enviornment except in humongous doses such as when heavy industry produces it as a byproduct or municipalities dump raw sewage into Lake Erie and Lake Ontario providing the famous soap foam crown to the Great Lakes back in the 60's.
Also, if one is concerned about phosphates and JUST DOESN'T FEEL COMFORTABLE - then Savogran provides a
Phosphate Free Tri-Sodium Phosphate ????, and is available in places such as the entire State of New York -- Right Cecil
Oh and surprisingly the
Phosphate Free Tri-Sodium Phosphate, works almost as well as the real stuff which I learned at CubFest Northeast 2006
