“…However, when the TSS is filtered from the wastewater solution the two materials have similar adsorption capacities regardless of the initial concentration. Due to the high surface area and adsorption capacity of TSS, both materials have an affinity to accumulate a significant amount of COD (Mulligan et al, 2009). This effect can be seen with the increased COD -T and nutrient adsorption capacity for each material in the presence of TSS compared with the filtered adsorption tests.…”

a b s t r a c tGranular wood-derived biochar (BC) was compared to granular activated carbon (GAC) for the treatment and nutrient recovery of real wastewater in both batch and column studies. Batch adsorption studies showed that BC material had a greater adsorption capacity at the high initial concentrations of total chemical oxygen demand (COD -T ) (1200 mg L Elemental analysis showed that both materials accumulated phosphorous during wastewater treatment (2.6 ± 0.4 g kg À1 and 1.9 ± 0.1 g kg À1 for BC and GAC respectively). They also contained high concentrations of other macronutrients (K, Ca, and Mg) and low concentrations of metals (As, Cd, Cr, Pb, Zn, and Cu). The good performance of BC is attributed to its macroporous structure compared with the microporous GAC. These favorable treatment data for high strength wastewater, coupled with additional lifecycle benefits, helps support the use of BC in packed bed column filters for enhanced wastewater treatment and nutrient recovery.

“…Padatan tersuspensi terdiri dari partikel-partikel yang ukuran maupun beratnya lebih kecil dari pada sedimen, seperti bahan-bahan organik tertentu, tanah liat dan lainnya (Fardiaz, 1992;Mulligan et al, 2009;Borkman dan Smayda, 2016;Raycraft et al, 2017). Hasil uji laboratorium menunjukkan dari 35 titik pengambilan sampel menunjukkan 18 titik berada di atas batas ambang baku mutu (50 mg/l), dengan konsentrasi TSS tertinggi adalah 139.48 mg/l yang terletak di kali Kungkuk desa Sumberejo (Gambar 7).…”

ABSTRAKPerkembangan setiap sektor pembangunan akan membawa dampak negatif terhadap lingkungan, begitu juga dengan perkembangan sektor pertanian menjadi agroindustri. Salah satu dampak negatif dari perkembangan kegiatan pertanian adalah usaha intensifikasi pertanian melalui penggunaan pestisida yang berpotensi mencemari air sungai. Identifikasi terhadap kesesuaian penggunaan lahan pertanian serta tingkat pencemaran air sungai oleh penggunaan pestisida merupakan langkah awal dalam usaha menjaga sumberdaya alam akibat usaha intensifikasi pertanian. Metode penelitian yang digunakan terdiri dari dua metode yaitu analisa spasial untuk kesesuaian penggunaan lahan pertanian dan indeks pencemaran untuk mendeskripsikan tingkat pencemaran air sungai. Hasil penelitian menunjukkan bahwa luas lahan yang sesuai dengan peruntukan pertanian (Kelas I dan II) di kota Batu sebesar 1333.54 ha atau 6.78%, hasil evaluasi kelas kemampuan lahan menunjukkan ketidaksesuaian penggunaan lahan kondisi saat ini sebesar 25.67% dan berdasarkan RTRW sebesar 32.05%. Peningkatan ketidaksesuaian penggunaan lahan juga diperoleh dari perkembangan sektor pertanian dimana luas lahan pertanian yang dialokasikan 3289.756 ha lebih dari luas lahan pertanian yang tersedia. Tingkat pencemaran air sungai DAS Brantas hulu kota Batu berada pada status pencemaran ringan sampa berat dengan indeks pencemaran terendah 0.92 (kondisi baik) berada di sumber Brantas dan tertinggi 245.39 pada sungai Ngujung, desa Pandanrejo. Usaha intensifikasi pertanian di kota Batu juga memiliki kontribusi terhadap penurunan kualitas air di DAS Brantas Hulu

“…Coagulation is a kind effective method to remove algae by which small particles are connected to each other forming flocs large enough to be separated from solution in a reasonable amount of time. And sand filtration is the conventional treatment way, and the major disadvantage, however, of the sand filters is that during filtration of water of high turbidity, the filters will clog frequently and thus require longer filtration periods and extensive cleaning [5]. It was reported that ultrasound effectively reduced the growth rate of algae by collapsing the gas vesicles during cavitation, inhibiting cell division, or inflicting immediate damage on photosynthetic activities [6].…”

This paper described the reductions ofMicrocystis aeruginosa and Anabaena flos-aquae using enhanced coagulation/electro-flotation process. A L 9 (3 4 ) orthogonal test including pH value，PAC doses，electric current and coagulation time is designed to remove algae in paper. Analysis of the removal of two major water-bloom algaes, viz Microcystis aeruginosa and Anabaena flos-aquae is addressed in paper by enhanced coagulation/electro-flotation process. The best removal of Microcystis aeruginosa and Anabaena flos-aquae achieved 93.33% and 96.47% respectively. The analysis of variance and range to the result of experiment indicates that coagulation process plays major role and pH value has the most remarkable influence.
