General Design Information

Municipal Wastewater

Numerous empirical equations have been developed in an attempt to mathematically describe the reaction taking place in the trickling filter. The most common and generally accepted empirical equation in use today

for predicting trickling filter performance in secondary treatment applications is the modified Velz equation. MARPAK MXF Series media performance for secondary treatment (Figs. 8-1 and 8-2) can be evaluated using the modified Velz equation.

For information regarding the application of MARPAK MXF Series media for nitrification of municipal wastewater, please reference Figs. 9-1 and 9-2.

Industrial Wastewater

MARPAK MXF and MCR Series media can be used to treat a variety of industrial waste streams. Due to the wide variation in treat ability of industrial wastes, trickling filter performance is best determined from data from trickling filter installations treating similar wastewater; general design curves for various categories

of industrial wastewater; or pilot studies. In addition to clarification, pretreatment including pH adjustment and nutrient addition may be required. The wastewater entering the trickling filter should have a pH between 6.0 and 8.5 and a nutrient balance among BOD, ammonia nitrogen and phosphorous of 100:5:1.
