    I  haven't tried this myself, but I would suggest trying to filter
    it through 2- 3 coffee filters placed in a large cone-shaped funnel. 
    Allow gravity to do the work.  If that won't do it, get some
    circular filter paper (say 15 cm in diameter, from a science supply
    company.  It should be a "fast" type of paper to allow filtration in
    a reasonable time. 

Good luck,
Brian
