“…Aziz et al (2007) suggested that landfill leachate color is mostly contributed by organic matter and some insoluble substances, which also contribute to turbidity and SS readings. A number of substances such as fine organic and inorganic matter, as well as algae (phytoplankton) and other microscopic organisms, such as bacteria (Zemmouri et al 2012), also cause turbidity. With the addition of more coagulant, electrostatic forces decrease and more flocs are formed, thereby reducing turbidity.…”

Malaysia is one of the highest starch producers. In this study, sago starch was utilized as a natural coagulant aid to reduce the dosage of aluminum-based coagulant in leachate treatment. The potential of native sago trunk starch (NSTS) and commercial sago starch (CSS) was evaluated as sole coagulant and coagulant aid in the presence of polyaluminum chloride (PACl) in the removal of color, suspended solids (SS), NH3-N, turbidity, chemical oxygen demand, organic UV254, Cd, and Ni. Leachate was sampled from Pulau Burung Landfill Site, one of the semi-aerobic landfills in Malaysia. The optimum dosage for PACl in the presence of NSTS or CSS as coagulant aid was reduced from 3100 to 2000 mg/L. In the presence of 2000 mg/L PACl with 6000 mg/L NSTS and 2000 mg/L PACl with 5000 mg/L CSS, the removal performance for color, SS, and turbidity are 94.7, 99.2, and 98.9%, respectively. Similar results were obtained with the use of 3100 mg/L PACl alone. Therefore, CSS and NSTS can be used as coagulant aid.

“…Deasetilasi kitosan secara bertahap akan menghasilkan DD yang lebih baik daripada secara kontinyu dengan total waktu yang sama, sebagaimana penelitian (2009) (Zemmouri, H., 2012) bahwa kitosan bersifat hidrofilik polimer mempunyai gugus amina sebagai polikationik, pengkelat dan pembentuk dispersi dalam larutan asam asetat organik maupun inorganik. Pada penyesuaian pH terhadap penentuan dosis optimum ditambahkan dosis kapur 2% pada masing-masing sampel limbah cair hingga pH pada sampel limbah cair 1 menjadi 7,15.…”

AbstrakIndustri rumah tangga pembuatan sarung tenun Samarinda menghasilkan limbah cair dengan konsentrasi TSS dan warna yang melebihi baku mutu sehingga memerlukan pengolahan sebelum dibuang ke badan air. Salah satu unit pengolahan yang dapat digunakan adalah unit koagulasi flokulasi dengan menambahkan koagulan. Jenis koagulan yang dapat digunakan salah satunya adalah koagulan dari bahan alam yaitu berasal dari kitosan limbah cangkang kepiting. Tahapan penelitian ini dimulai dengan mempersiapkan koagulan dari kepiting dengan tahapan isolasi kitin yang meliputi tahap demineralisasi, deproteinasi, deasetilasi. Tahap selanjutnya adalah dengan metode jar tes untuk menentukan dosis optimum untuk menurunkan parameter TSS dan warna dari limbah tenun sarung Samarinda. Analisa laboratorium dilakukan terhadap parameter pH, TSS, warna, volume flok yang terbentuk selama jar test. Hasil penelitian dari analisa FTIR menunjukkan bahwa limbah cangkang kepiting mempunyai derajat deasetilasi sebesar 74,25% yang menunjukkan sebagai kitosan yang mengandung gugus amina dalam rantai karbonnya yang bermuatan positif sehingga dapat berfungsi mendestabilisasi koloid yang bermuatan negatif. Dosis optimum pada pengolahan limbah cair ini dengan menggunakan kitosan 1% sebesar 35ml dengan efisiensi removal TSS 88,79% dan warna 35,49%. Namun terjadi penurunan nilai pH menjadi 4,98 disebabkan penggunaan asam asetat sebagai pelarut kitosan.

“…The suspended particles vary considerably in source, composition charge, particle size, shape, and density. Correct application of coagulation and flocculation processes and selection of the coagulants depend upon the understanding of the interaction between these factors [4,5,6]. In practice, the coagulation is carried out by coagulants, where the hydrolysis products cause electrolyte coagulation and the coagulation by the colloid with an opposite sign.…”

Abstract. Coagulation is one of the processes of water and wastewater treatment. During this process, flocs are formed and are characterized by different shapes, structures and dimensions. Due to this fact, removing of these particles may produce some problems for researchers because the sedimentation way of this particles is disturbed. In this paper, the method of flocs classification is presented where coefficients k 1 , k 2 and k 3 were calculated. An appropriate value of coefficient k enables the classification of the considered particle to a specific group. The idea of the classification method consists in calculating surface areas for a particle image registered using a microscope. After that, the images are analyzed (computer image processing). The analyzed images will be used for future studies, in which the settling phenomenon will be described.
