“…Comparative study between M. oleifera and alum as coagulant on tofu wastewater was held on 100 rpm rapid mixing for 3 minutes and 40 rpm slow mixing for 15 minutes. This study reported that at 2,000 mg/L coagulant dose, M. oleifera provided higher TSS removal than alum [6]. The use of 600 mg/L dosaged of M. oleifera and 200 mg/L dosage of alum on domestic wastewater achieved 69 ± 8% and 85 ± 6% of TSS removal, respectively [19].…”

“…On the other hand, increase in organic matter in treated water which comes as the aftermath of usage of crude plant extract which is considered as disadvantage may be diminished by purification of active coagulant compound [5]. Application of natrual coagulant derived from Moringa oleifera on tofu wastewater has been done and showed high efficiency in BOD, COD and TSS removal [6]. The coagulation process can also be combined with anaerobic [7, 8,9 10] and phytoremediation processes [11].…”

Present study investigates the ability of tapioca and corn flour for turbidity, total suspended solids (TSS) and chemical oxygen demand (COD) removal from tofu wastewater. The active coagulant agent were succesfully extracted from tapioca and corn flour using NaCl (namely tapioca and corn extract) and Amberlite resin (namely tapioca ionic and corn ionic). Experiment were conducted in batch mode for initial turbidity of 527 NTU, initial TSS 740 mg/L and initial COD 13,015.04 mg/L. Results demonstrated that tapioca extract is less efficient in turbidity, TSS and COD removal compare to corn extract. Corn extract was found to provide high turbidity removal with efficiency of 71% and TSS removal with efficiency of 35%. Meanwhile, corn ionic was reported have the highest ability in COD removal and reached 31.71% efficiency. Thus, the natural coagulants extracted from NaCl and Amberlite resin revealed to be effective only for turbidity removal.

“…Akan tetapi pada penambahan koagulan tawas sebanyak 1500 mg/L memiliki nilai efisiensi penurunan sebesar 70,7%, hasil tersebut masih tidak memenuhi standar baku mutu dikarenakan tawas (Al2SO4) tidak mampu mengikat partikelpartikel sisa koloid sehingga terjadi pengendapan dan penggumpalan flok dengan ukuran yang lebih kecil. Selain itu juga disebabkan karena ukuran partikel yang kecil tersebut mengganggu proses penyaringan sehingga masih ada padatan yang tertahan pada kertas saring [13]. Pada Gambar 4 hasil regresi korelasi parameter zat warna secara koagulasi menunjukkan garis yang semakin menurun sehingga dapat dijelaskan bahwa semakin tinggi massa koagulan tawas yang digunakan dalam mengolah sampel limbah cair batik Banten maka hasil parameter zat warna akan semakin berkurang dan memenuhi standar baku mutu.…”

The batik industry produces liquid waste from the coloring, washing and rinsing processes. This study was aimed to analyze the quality of Banten batik effluent before and after treatment. The processing is carried out using an experimental method with a batch system by coagulation using alum and adsorption using Bayah's natural zeolite by performing 3 variations of coagulant mass and adsorbent for the dye test parameters, TDS and TSS. The results of the test before treatment were the results for dyes of 344 TCU, TDS 620 mg/L, and TSS 218.5 mg/L. Based on the coagulation treatment using alum, the most efficient coagulant results were obtained to reduce the levels of dyestuffs and TDS, namely by using alum coagulant as much as 1500 mg/L which resulted in 96.6 TCU and 330.0 mg/L respectively, then to reduce TSS levels obtained an efficient coagulant that is 500 mg/L with a yield of 10 mg/L. The adsorption treatment using Bayah natural zeolite can reduce the levels of TDS and TSS with the most efficient results using an adsorbent of 150 g/L obtained for TDS 189.3 mg/L and TSS 13.3 mg/L. So based on the results of processing using coagulation and adsorption methods, it is hoped that the batik industry can apply it in processing the liquid waste produced.

“…Liquid waste flowing into rivers can contaminates and cause health problems in the form of itching, diarrhea, cholera, intestinal inflammation, and other diseases, especially those related to blood. In addition, the river water will become dirty and cause poor sanitation [7]. Therefore, it is necessary to treat tofu industrial liquid wastes before disposal in order to achieve the quality standards determined by the Indonesian Minister of Environment Number 5 of 2014 [5].…”

<p>Tofu waste is gotten after processing soybean, and this waste contains a lot of polluting substances, hence it can pollute rivers and cause health problems. Meanwhile, one method used for treating wastewater into clean water is called the jartest method and its processes include coagulation-flocculation and deposition. This study aims to determine the effectiveness of green mussel shells as coagulants in the treatment of tofu industrial liquid waste. The variables used were 100 mesh green mussel shell powder, 1000 mL of liquid tofu dregs, 150 rpm fast stirring speed for 2 minutes, and 60 rpm slow stirring speed for 15 minutes. Furthermore, chitosan was used with different weight variations in grams (0.5, 0.7, 0.9, 1.1, and 1.3) as well as precipitation time with variations in minutes (20, 30, 40, 50, and 60). The content of Chitosan water was 1.29% and its degree of deacetylation was 65.04%. The result of the preliminary analysis of tofu liquid waste with a coagulant showed BOD, COD, and TSS levels of 965.25mg/L, 435mg/L, and 395mg/L with pH 4 respectively. However, these levels were changed to 195.56mg / L; 299mg/L; and 195.32 mg/L with pH 6 after the final analysis of the liquid waste was conducted.</p>
