Waste containing dyes causes visual pollution and increase the risk of environmental health issue. The aim this study was to determine best operating conditions jumputan liquid waste treatment using bottom ash batubara agar wood with variations in feed flow rate (1, 2, 3 l/min), filtration time (30, 60, 90, 120 mins), treatment. results are compared parameters Biochemical Oxygen Demand (BOD), C...

Limbah cair tahu dapat menimbulkan pencemaran karena terdapat kandungan biological oxygen demand (BOD), chemical demond (COD), dan total suspended solid (TSS) yang sangat tinggi mencemari lingkungan sekitar apabila dibuang ke sungai. Sebab itu kadarnya harus diturunkan sebelum sungai sekitar. Yaitu dengan cara mengolah limbah biofilter. Biofilter digunakan yaitu bermedia filter batu krikil kora...

Industri tahu rumahan pada proses produksinya dapat menghasilkan limbah cair dan padatan. Sedangkan teknologi yang digunakan masih sederhana, sehingga tingkat efisiensi penggunaan sumber daya (air bahan baku) sangat rendah produksi limbahnya tinggi. Sehingga menyebabkan air menjadi kotor bau. Tujuan penelitian ini adalah untuk mengetahui karakteristik kinerja dari membran di buat. Metode lakuka...

Introduction: Paper and paperboard industry wastewater has potentially damaging effects on the ecosystem of the receiving environments due to the presence of toxic compounds. As a result, the treatment of such wastewater is necessary prior to discharge into the environment. In this study, the potential of Plantago major L. seed extract as a natural coagulant in treating paper and paperboar...

The effect of fig freezing in sugar solution on fig’s quality and sensory traits as well phenolic content during storage was examined. Fresh figs were frozen without any treatment (control - CON), sucrose (30%) (SUC) with ascorbic acid (2%) (SUCAA), stored at -18 ⁰C for 210 days. Samples analyzed every seventy days pH, total soluble solids (TSS), sugars phenolics composition, skin pulp color, t...

Buriganga, an economically important river located around the industrialized urban area of Dhaka city, Bangladesh. In this study, 17 water quality parameters (EC, pH, TSS, temperature, F-, Cl-, SO42-, Cr,...

Abstract Biopulping is a process that carried out before fiber ripening using chemicals in the pulp process. The use of black liquor biopulping can reduce pollution due to chemicals. This study aims determine effect on characteristics liquid waste oil palm empty fruit bunches (OPEFB). Observations made include BOD 5 , COD, TSS, and pH. used completely randomized research design with three repli...

in this study the effects of plant growth regulators including; ga3 (0 and 50 mg/l) and ethephon (0 and 500 mg/l) were studied on the quality properties of two grape cultivars (perlette and yaghuti). at the harvest time, some physicochemical characteristics such as fruit cluster weight, fruit diameter, length, volume and l/d ratio, flesh firmness, fresh weight, ta, ph, tss and fruit color were ...
