I am looking for an efficient defloculating agent that will help break the 
flocs of activated sludge samples.  Back in 1970, Gayford and Richards 
found that a mixture of sodium pyrophosphate and Lubrol were very 
efficient.  Does any one know Lubrol is still on the market, or any other 
similar detergent?   Any info will be very much appreciated.
