Sample text

The ability of the granular media filter beds to produce a clear effluent results from the straining action and adhesion, which removes particles finer than the pore space. Surface Filters make use of a fine medium such as a cloth or close mesh screen. In the rotary vacuum filter,-the medium is in the form of a continuous belt and it rotates over a perforated drum that is partially submerged in the slurry to be filtered. Water is pulled through the filter cake that forms on the belt to the inside of the drum, where it is transferred to the vacuum system.

Some alternative pretreatment systems used are chemical treatment in activated sludge, roughing filters, and trickling filters. In addition to the separate stage trickling filter, Rotating Biological Contactors are very adaptable to separate stage nitrification. The purpose for RBD combined carbon oxidation/nitrification may be applied to separate stage nitrification. The only difference is if the secondary effluent being treated has a BOD, or suspended solids content of less than 20 mg/l, the secondary clarifier may be eliminated.

Another solidification process uses a reagent called Urrichem that immobilizes slurried hazardous components. The contaminated soil is excavated and intimately mixed with the Urrichem off-site. After blending, the slurry is pumped out of the mixer and hardens into a concrete like mass within 24 hours. Chemfix is a process developed by Chemfix Technologies (Metaire, LA). In this technique, a proprietary blend of soluble silicates and additives is used to convert high molecular weight organic and inorganic slurries into a cross-linked, clay like matrix.
