“…An active culture of acclimated pig wastewater nitrifying bacteria was prepared from overland flow soil seed. The ammonia strength of the salts medium was gradually increased to overcome inhibitory effects caused by high levels of free ammonia in pig wastewater, similar to procedures used for acclimation of marine nitrifiers (Furukawa et al 1993). Acclimated nitrifying cells were immobilised in 3-5 mm polyvinyl alcohol polymer cubes.…”

Nitrification is a necessary and often limiting process in animal waste treatment for removal of nitrogen as N 2 through biological nitrification/denitrification systems. We evaluated three technologies for enhancing nitrification of pig lagoon wastewater prior to denitrification: overland flow, trickling filter, and a bioreactor using nitrifying pellets. The overland flow system consisted of a 4 × 20m plot with 2% slope with a subsurface impermeable barrier receiving a total N loading rate of 64-99 kg N ha-1 day-1. Total N removal efficiency ranged from 36 to 42%, and 7% of the total N application was recovered in the effluent as nitrate. The trickling filter consisted of a 1-m 3 tank filled with marl gravel

“…Also, it is possible to store excess sludge anaerobically up to four days to serve as backup sludge for restarting the plant. Whereas Salem et al (2005) found that the decay rate of ammonia oxidizers after 14 days of starvation at 20°C was 0.02 day -1 , Furukawa et al (1993), who stored the nitrifiers in a refrigerator for 6 days, reported that the pellets of acclimated marine nitrifying sludge could regain their full activity.…”

“…In biological ammonia removal systems, nitrifying activity of suspended bacteria has been reported to be extremely low, due to slow growth rate and inhibition of nitrification by free ammonia and nitrite under the alkaline conditions of seawater (Bower and Turner 1981;Furukawa et al 1993). Without the addition of nitrifiers as start-up cultures, 2-3 months are needed to establish nitrification in marine systems (Manthe and Malone 1987) and 2-3 weeks in freshwater (Masser et al 1999).…”

Stringed bed suspended bioreactors (SBSBR) for in situ nitrification in penaeid and non-penaeid hatchery systems

For establishing nitrification in prawn (non-penaeid, salinity 10-15 ppt) and shrimp (penaeid, salinity 30-35 ppt) larval production systems, a stringed bed suspended bioreactor (SBSBR) was designed, fabricated, and validated. It was fabricated with 5 mm polystyrene and low density polyethylene beads as the substrata for ammonia and nitrite oxidizing bacterial consortia, respectively, with an overall surface area of 684 cm 2 . The reactors were activated in a prototype activator and were transported in polythene bags to the site of testing. Performance of the reactors activated with the nitrifying bacterial consortia AMONPCU-1 (ammonia oxidizers for non-penaeid culture) and NIONPCU-1 (nitrite oxidizers for non-penaeid culture) was evaluated in a Macrobrachium rosenbergii larval rearing system and those activated with AMOPCU-1 (ammonia oxidizers for penaeid culture) and NIOPCU-1 (nitrite oxidizers for penaeid culture) in a Penaeus monodon seed production system. Rapid setting up of nitrification could be observed in both the static systems which resulted in a higher relative per cent survival of larvae.Keywords Closed system shrimp hatchery Á Immobilization Á Nitrification Á Nitrifying bioreactors Á Nitrifying consortia Á Shrimp/prawn larval production Abbreviations AMONPCU-1 Ammonia oxidizers for non-penaeid culture AMOPCU-1 Ammonia oxidizers for penaeid culture IHHNV Infectious hypodermal and hematopoietic necrosis virus
