Abstract

Ammonia compound is chemical compounds abundance in nature.Ammonia wastes discharge into water body will have a negative impactand cause ecological and healthy problems. High concentration ofammonium will give eutrofication problem in water body therefore dissolveoxygen demand will be decreased as well as self purification of waterecosystem. This negative impact will influenced for aquatic organismwhich died gradually. The efforts decrease of ammonia concentration isby biological waste water treatment utilizing microbes for changingammonia to nitrite and nitrate. One of the technologies could be carriedout is nitrification process technology using biofilter with 80% efficiency.For decreasing ammonia concentration can be used biological treatmentby using microbe which can change it ti nitrite and nitrate

Abstract

Pollution in the rivers is generally caused by domestic and industrial waste.Some treatments to solve it can be done individually or collectively. Theeffort can be physical, chemical, or biological treatments chosen by itsform, character, kind, quality, quantity. PT Van Melle Indonesia is a candycompany which produces a high biological waste with COD concentration10000-30000 mg/litre. This paper reports activated sludge reactorperformance to decrease the waste’s organic content. The reactor is abiological waste water treatment, as a sequence of earlier anaerob processwhich still has a high COD (700-4000 mg/litre). A continued reactoroperation done with retention time variation 24 hours, 18 hours, 12 hours,and 6 hours show reduced COD varied 80-90%. The highest efficiencywas 97.59% from the 24 hours retention time, and the lowest efficiencywas 89.5% from the 6 hours retention time.

Abstract

A laboratory experiment on utilization of seaweed-containing solid wastes as media for growing mushrooms was conducted by researchers from the Institute for Environmental Technology. The solid wastes were obtained from PT. Agarindo Bogatama, a food industry which produces jelly powder processed from seaweed of Gracilaria. The company generates 60 tones of solid wastes of seaweed per-day that contained 70% of water content. The solid media was used to grow Auricularia polytricha, Pleurotus astreatus, and Ganoderma lucidum. Some mixed media were prepared with the percentage ratio of sawdust to solid waste as 0, 25, 50, 75, and 100. After sterilizationthe media were planted with mushrooms and then were kept in incubator. After 28-day the basidiomas of G. lucidum was developed while P. astreatus appeared after 36-day of incubation. Both were grown on 100% seaweed media (using 100% sawdust media as a control). This very early results indicated that solid waste of seaweeds have an additional value which can be used as media for mushrooms plantation. Implementation waste to product as a part of cleaner production approach should be disseminated to the industries, especially SMEs like PT. Agarindo Bogatama, who areconcern to the environment.
