To reduce the organic substance and ammonia in raw water hence raw water from river have to be processed by pretreatment prior to main processing unit. One of the alternatives is biological treatment using submerged biofilter which filled with honeycomb plastic supporting media. Research conducted by operating continuous flow biofilter reactor wich filled with honeycomb plastic supporting media. The size of biofilter reactor is 59 cm x 30 cm x 210 cm, with total volume 371.7 litres.  The research was conducting by continuous operation under condition 4 hours, 3 hours, 2 hours and 1 hour retention time. The result of experiment shows that within the biofilter process under conditions 4 hours, 3 hours, 2 hours and one hour retention time, the removal efficiency of organic substance were 67.27 %, 53,89 5,45.70 % and 30.92 % respectively. And the removal efficiency of ammonia under conditions 3 hours, 2 hours and one hour retention time were 73.59 %, 67.98 %, and 48.74 % respectively. The longer retention time has resulted in higher removal efficiency. By combining biofiltration process with ultra fltration (UF) membrane technology, hence will be got technological alternative of drinking water process which able to degrade an organic matter and ammonia without chemicals instead of convensional process.  Kata Kunci : biofiltasi, membran, ultra filtrasi, air minum.

Rural sanitary pollution has become the major source of nitrogen and phosphorus pollutants flowing into China's Taihu Lake region. The treatment process of rural sanitary sewage should be consistent with the economic and social development in rural areas as well as the natural and geographical conditions. Biological and ecological treatment combination processes should include biological treatment unit and ecological processing unit. The biological treatment unit can achieve the degradation of organic matter and the inorganic treatment of nitrogen and phosphorus, while and ecological processing unit functions as the advanced treatment and resource utilization of nitrogen and phosphorus. Demonstration projects demonstrate that the combination processes can effectively remove organic matter, nitrogen and phosphorus, performing with low processing costs, simple operation and maintenance and suitable for application and popularization in rural areas.

In big cities of Indonesia using river water as raw water PAM (drinking water company). The concentration of organic matter and ammonia in the raw water PAM is increasing due to industrial and domestic waste pollution. Biofiltration combination with ultrafiltration process is use as one alternative to reduce  concentration of organic matter, ammonia, iron, manganese and turbidity in raw water. In this treatment, biofilter reactor is use with plastic of Honeycomb tube type as media combined with ultrafiltration. Operational condition of treatment is variation of HRT (Hydraulyc Retention Time) between 1–4 hours and air supply between 0–30 l/min. The selected operational condition of treatment found at HRT of 2 hours and air supply of 20 l/min, with removal efficiency of concentration of organic, ammonia,iron, manganese, and turbidity are 68 %,65 %, 68 %, 67 %, and 72 % respectively.  Keywords:  Biofiltration, ultrafiltration, honeycomb tube, removal efficiency, drinking water.

A study to improve the raw water quality at Taman Kota Drinking Water Company was conducted by using pilot plant of biofiltration system. The pilot plant was run by pumpingthe raw water from river to the reactor continuously with various Hydraulic Retention Time. Samples of raw water and treated water were taken daily and analyzed for pH,Total Suspended Solid (TSS), Organic matter, Ammonia nitrogen and Detergent (MBAS). The results showed that performance of biofiltration system decreaed due to shortening Hydraulic Retention Times (HRT). The longer HRT caused bigger volume of biofiltration tank. Therefore, this study suggests that the optimum Hydraulics retention time is 1 hr. In this HRT, the treated water quality were 7.2 for pH, 40 mg/l for TSS, 10,7 mg/l for organic matter, 0.35 mg/l for ammonia nitrogen and 0.1 mg/l for MBAS. These resultscomply with the Regulation No. 582 year 1995 for raw drinking water quality (class B).

Organic Matter Removal

The aim of this work was to evaluate the removal of suspended solids (SS) and 7-day biochemical oxygen demand (BOD7) in a three chamber septic tank depending on theoretical wastewater retention time and the degree of septic tank cleanliness. It was found out that the performance of the septic tank depended on the degree of its cleanliness: when the septic tank was clean and retention time was three days, SS and BOS7 removal efficiency was 77±10% and 67±14% respectively, whereas two months later, after septic tank desludging, SS removal efficiency decreased to 53±22% and BOD7 to 32±31%. The performance of the septic tank also depended on theoretical wastewater retention time: when some amount of solids was accumulated at the bottom of the septic tank and wastewater retention time was one day, SS and BOS7 removal efficiency was 45±40% and 33±16% respectively; when retention time was three days, SS removal efficiency increased to 53±22% but BOD7removal efficiency remained similar to one day retention time, i.e. 32±31%. Santrauka Bandymų metu buvo įvertintas organinių ir skendinčiųjų medžiagų šalinimas trijų kamerų septike esant vienos ir trijų parų teorinėms nuotekų išbuvimo septike trukmėms bei skirtingam septiko švarumo laipsniui – iš karto po septiko išvalymo, kai jis dar yra švarus, ir praėjus tam tikram laiko tarpui, kai ant septiko dugno yra susikaupęs tam tikras nuosėdų kiekis. Tyrimais nustatyta, kad septiko veikimas priklauso nuo septiko švarumo laipsnio: esant trijų parų nuotekų išbuvimo septike trukmei, vidutinis skendinčiųjų medžiagų (SM) šalinimo efektyvumas buvo 77±10 %, o septynių parų biocheminio deguonies suvartojimo (BDS7) – net 67±14 %, kai septikas buvo švarus, tačiau praėjus dviem mėnesiams nuo septiko išvalymo jo veikimas pablogėjo ir vidutinis SM šalinimo efektyvumas po septiko išvalymo buvo 53±22 %, o BDS7 – 32±31 %. Taip pat nustatyta, kad šalinant teršalus didelę reikšmę turi nuotekų išbuvimo septike trukmė: kai septikas buvo švarus, o nuotekų išbuvimo trukmė trys paros, vidutinis SM šalinimo efektyvumas – 77±10 %, o BDS7 – 67±14 %; sumažinus nuotekų išbuvimo trukmę iki vienos paros, SM šalinimo efektyvumas sumažėjo iki 31±38 %, o BDS7 šalinimo efektyvumas buvo neigiamas.

The Effect of Cellular Organic Matter Produced by Cyanobacteria Microcystis Aeruginosa on Water PurificationThe aim of this paper is to investigate the influence of COM (Cellular Organic Matter) produced byMicrocystis aeruginosaon the process of water purification by destabilisation and subsequent aggregation of the impurity particles. The research was carried out with a raw water into which COM was added. The removal efficiency of the most significant components of COM, i.e. polysaccharides and proteins, was investigated. It was found that the removal efficiency of polysaccharides and proteins was dependent on the reaction conditions (pH, type of destabilisation reagent and its dosage). The removal efficiency of COM was relatively low. It was about 46% and 41% using ferric sulphate and aluminium sulphate aggregation, respectively. In comparison to the other organic components of COM, mainly polysaccharides, the proteins are removed with a higher efficiency. The GPC analyses of the residual COM showed that the proteins of higher molecular weight were aggregated with a higher efficiency.

A single full-scale primary facultative pond in Sapé, north-east Brazil was monitored for performance and efficiency. The pond had a hydraulic retention time of 61 days and achieved a 95% BOD5 removal efficiency and had no helminth eggs in the effluent. The effluent failed to meet the WHO faecal coliform guideline for unrestricted irrigation. The pond was dominated by the cyanobacterium Microcystis and gave better than predicted orthophosphate removal. Details of how the system could be simply upgraded utilizing the same land are discussed.
