What are the operational problems of trickling filter?
Following are the various types of troubles which occasionally occur at the site and operation of trickling filters: 1. Odour Nuisance 2. Ponding Nuisance 3. The Fly Nuisance.
What is the design criteria for trickling filter?
The trickling filter design must evaluate the impacts of recirculation, air draft temperatures and medium. Recirculation capability is required for all variations of the trickling filter process except roughing filters provided that minimum hydraulic loading rates are maintained at all times.
What are the disadvantage and advantage of trickling filter?
Limited flexibility and control in comparison with activated sludge processes. They require high maintenance costs of rotary distributor center mechanisms. Any maintenance service for the rotary distribution mechanism would require a crane and complete removal of the rotary distributor mechanism, guy rods, and arms.
How can I improve my trickling filter?
The performance of some trickling filter plants can be improved with minor additions or revisions, e.g.: 1. Additional recirculation pumping capacity may be provided by installing larger pump impellers with higher horsepower motors. Plant performance will be improved.
What is trickling filter with diagram?
A trickling filter is a type of wastewater treatment system. It consists of a fixed bed of rocks, coke, gravel, slag, polyurethane foam, sphagnum peat moss, ceramic, or plastic media over which sewage or other wastewater flows downward and causes a layer of microbial slime (biofilm) to grow, covering the bed of media.
Which type of bacteria are used in trickling filter?
Which type of bacteria are used in trickling filters? Explanation: Facultative bacteria are used in trickling filters. Pseudomonas and Alcaligenes are some of the strains used in these filters. Also, Flavobacterium and Achromobacter are also used in this type of treatment.
What are the types of trickling filter?
TYPES OF TRICKLING FILTERS
- 1 Low Rate Trickling Filter (LRTF)
- 2 High Rate Trickling Filter (HRTF)
- 3 Roughing Filter.
- 4 Two-Stage Trickling Filters.
What are the factors that will affect the efficiency of the trickling filter treatment?
There are several major factors that influence the kinetics of nitrification. These are organic loading, hydraulic loading, temperature, pH, dissolved oxygen concentration, and filter media.. 1. Organic loading: The efficiency of the nitrification process is affected by the organic loadings.
What are the advantages and disadvantages of trickling filters?
ADVANTAGES AND DISADVANTAGES OF TRICKLING FILTER
- Effective in treating high concentrations of organic material depending on the type of media used;
- Very efficient in removal of ammonia from wastewater;
