Abstract:
Storage of Spirulinu mats with three factors, light intensity, substrate concentration and storage time were studied before the
use of them for nutrient removal.
During storage, light intensity had more effects to Spirulinu than substrate concentration. The brown color (inhibited or dead
cell) was observed after six weeks of storage under light intensity of 1000 lux. Suspended solid from Spirulinu mat kept under
3000 lux and lx Zarrouk's medium was highest at six week storage due to the detachment of excess growth cells on the mat.
In contrast, suspended solid k m Spirulina mat kept under 1000 lux light intensity and 0.k Zamuk's medium was also high due
to detachment of dead cells.
After storage, the Spirulina mats were tested in circulated batch system for ammonia removal by using simulated shrimp
culturing water with ikitial ammonia of 1 mg-NI1, phosphorus of 0.3 mg-PI1 and water velocity of 0.14 d s . Steady state
ammonia concentration in effluent by fresh Spirulinu mat was 0.127 mg-N11 and by the Spirulinu mats kept to six weeks
in lx Zarrouk's medium under 3000,2000 and 1000 lux were 0.18 1,O. 194 and 0.1 86 mg-Nll , respectively. Effluent ammonia
concentration by Spirulinu mat after stored in 0.5% 0.3x and 0.k Zarrouk's medium and under 1000 lux light intensity were
0.197,O. 199 and 0.233 mg-N/1 respectively. Phosphorus concentration in effluents of all efficiency tests were still high.
Concentration of suspended solid that daily washed out was found stable in all reactors.
Optimal condition for storage Spirulina mat for long term period (six weeks) was light intensity of 1000 lux and 0 . 3 x Zarrouk's
medium.
