2] have shown that high rate tertiary nitrification could be achieved in cross- flow media trickling filters.
The selected biological wastewater treatment plant is based on the so-called combined conventional activated sludge and trickling filter having the following components as shown in Fig.
Trickling filter for nitrification of sludge liquor and internal recirculation
As further main target is the complete denitrification of nitrate which is produced in the trickling filters and transferred in to aeration tanks by a recirculation flow.
In order to achieve partial nitrification trickling filters are employed, which provide the following main advantages compared to other systems:
Trickling filters are employed for nitrification of ammonia contained in the highly concentrated filtrate from sludge dewatering.
Beside the transfer of ammonia to the trickling filters, the recirculation of final clarifier effluent also serves for dilution of the sludge dewatering filtrate in order to provide sufficient alkalinity in the trickling filters.
Weir lengths are sized so about 70 percent of the influent flow is routed to the new activated sludge plant and 30 percent to the existing trickling filter plant.
The remaining flows not entering the activated sludge package plant are directed to the trickling filter plant.
Trickling filter influent and effluent analysis results indicate that the equation of the National Research Council provided an accurate prediction of effluent [BOD.
The trickling filter has a vitrified clay block under-drainage system.
Flows from the activated sludge plant enter the inlet well by gravity, and the trickling filter plant effluent is pumped.
The digester receives primary sludge, trickling filter waste secondary sludge, and waste activated sludge.
