PENELITIAN PENURUNAN AMONIAK NH3 PADA LIMBAH BUATAN DENGAN TEKNOLOGI AIR STRIPPING

RESEARCH ON AMMONIA NH3 REMOVAL FROM SYNTHETIC WASTEWATER BY AIR STRIPPING TECHNOLOGY

Author :
Kusuma, Ferdyan Hijrah 




ABSTRAK

Salah satu permasalahan yang ada dalam air limbah domestik yaitu adanya kandungan amoniak NH3 yang cukup tinggi. Adanya amoniak dalam air limbah ini berpotensi mencemari badan air bila langsung dibuang tanpa melalui proses pengolahan. Untuk itu perlu adanya suatu teknologi pengolahan yang tepat. Metode air stripping adalah salah satu metode yang digunakan dalam usaha menurunkan kandungan amoniak dalam air limbah. Pada penelitian tekmologi air stripping ini didapatkan hasil bahwa perlakuan variasi besar debit Q1 125 mlmenit memiliki rentang penurunan konsentrasi amoniak lebih baik dibanding dengan perlakuan besar debit Q2 25 mlmenit dan Q3 20 mlmenit. Penurunan konsentrasi amoniak oleh kodisi Q1 yaitu antara 10 35. Sedang rentang penurunan konsentrasi amoniak yang terbaik diantara ketiga variasi konsentrasi awal adalah perlakuan konsentrasi awal X3 56 mgl yaitu sebesar 54 35 dibanding X1 154 mgl dan X2 952 mgl sebesar 16 327 dan 59 298. Untuk penggunaan media kelereng dengan tinggi sebesar R1 tinggi media 25 cm mempunyai rentang penurunan konsentrasi amoniak sebesar 5 35 ini lebih baik dibanding untuk R2 tinggi media 50 cm yang dan R3 tinggi media 100 cm sebesar . Rasio GL terbaik di miliki oleh R1 tinggi media 25 cm sebesar 178505. Sedang untuk R2 tinggi media 50 cm hanya sebesar 178503 dan R3 tinggi media 100 cm sebesar 178504.


ABSTRACT

There is one kind problem in domestic wastewater its contain high concentration of ammonia. Ammonia presence in a surface water potentally desecrate if not treat it before. Air stripping method is a one method which used to remove ammonia in wastewater. From this air stripping research there are some results that wastewater flow given as Q1 125 mlmin have ammonia removal ability better than Q2 25 mlmin and Q3 20 mlmin. Ammonia removal ability for Q1 about 10 35. The best ammonia removal ability betwen three diferent concentration is for wastewater which contained X3 56 mgl its about 54 35. And for X1 154 mgl dan X2 952 mgl about 16 327 and 59 298. If using marbels as media with condition like R1 depth of media 25 cm have ammonia removal ability 5 35 this is better than R2 depth of media 50 cm and R3 depth of media 100 cm. R1 depth of media 25 cm have GL ratio about 178505. For R2 depth of media 50 cm its just 178503 and R3 depth of media 100 cm about 178504.
