Manufacturing applications for alum sludge.
(OP)
Anyone having direct experience or knowledge of the processing of alum sludge for either, agricultural, manufacturing or reprocessing?
I would like to hear of your success or difficulties with the handling and material qualitites of Alum sludge.

p.s.: this is my first visit to this site and my first post. Cool site!
RE: Manufacturing applications for alum sludge.
The key is thorough chemical and physical charaterization, using special extractions to determine the materials ability to bind P.
The issue - high soil P contributes to water pollution, eutophication of lakes and estuaries, etc. Using these materials, our goal is to establish a BMP that can become incorprated with new Soil P Indexes as a P sink.
Let me know if you want to discuss further.

What issues have you encountered around the dewatering and crushing of your raw product. What effect do compositional variances have upon your product manufacturing.
Do you use engineered drying processes ie Fluid bed kilns or driers?
Have you investigated the comparable heat treatment processes used for mineral and sand drying?
My questions relate to a desire to make beneficial use of considerable local waste stream of alum and other sludges.
I am investigating broad areas of application from Civil construction material, specialised aggregates, filtration media, ceramics, etc.
I would greatly appreciate any references or information about such applications which you could direct my way.
