Have any of you any suggestion how to precipitate aluminum from a reduction reaction done with Vitride in Toluene. A basic water washing can not be done, cause the organic product is water soluble and addition of 3 mols of water to precipitate Al(OH)3 works but the solid is too sticky to be filtered properly

Hope you are concern is of the effluent disposal from this reaction.
To my understanding, sodium aluminate & 2-methoxy ethanol could be the contents of the effluent stream.
Instead of trying to precipitate Al(OH)3, would it not be better to think of changing the stream to a 38% or 45% liquid sodium aluminate that is a raw material for other industrial applications.
Hope this helps

Sometimes you can precipitate the aluminum salts and then effeciently extract your desired compound using a Soxhlet extractor, even if the solids are sticky.

Soxhlet can't be done at required scale and extracting aluminate as a concentrated solution we loose more than 70% of the organic product in the aqueous layer although the organic solvent is a very polar one.
any other suggestion?
