How to Remove Sludge and Clean a Heating Oil Tank
2. Use a Sediment Treatment. A heating oil additive or treatment can also prevent sludge buildup. If you add it to the tank before your next delivery, it will break down the sludge at the bottom of your tank. Look for a treatment that contains a sludge dispersant, which will break up the sediment and loosen it from the bottom.

powdered activated carbon (PAC) reagent used in water treatment
Activated carbon can be decompacted by installing an "intermediate hopper". A transfer screw or a rotary vane feeder feeds the hopper. The feeding system is mounted on the "intermediate hopper". Once the PAC has been decompacted, a volumetric feeding (screw-type feeder) then becomes feasible. PAC is a product having a widely varying density ...
