Planktons  have ability to live in aquatic ecosystem, including rivers ecosystem, estuary ecosystem, lake ecosystem and ocean ecosystem. The plankton abundance is estimated by correlation with water quality both of salinity, pH, temperature and others. This research aimed to analysis plankton abundance and to analysis correlation between plankton abundance and water quality. This research was conducted in Donan River using random sampling in 10 stations. The plankton are collected  using plankton net no 25 and Lackey Drop Mikrotranset Counting (plankton analysis) and APHA (2005) to analysis water quality. The results showed that the plankton abundance ranged between 524 – 6,406 ind L-1 and best correlation with water salinity had index 0.975. Keywords: plankton abundance, water quality, Donan river, water salinity, correlation

This research has been conducted with the tittle the diversity of gastropods on the river water environment Empayang Lahat regency of South Sumatra province. The aim of this research species diversity of gastropods contained the region. This research was implemented conducted in October 2015, a river Empayang Kasap Sukajadi Lahat regency. The methods of this research is purposive random sampling method with 5 sampling stations, each station is divided into three substations (edges first, middle, edge 2) was determined by linear transects (line transect). The data of the sample was taken in the morning and afternoon. The results of this research were obtained 8 species of gastropods (Melanoides granifera, Elimia acuta, Brotia tetidinaria, Lymnae stagnalist, Lymnae rubiginosa, Pomacea canaliculata, Pila polita and Menetus sp) with 7 genus, and of the six tribes (families) of 4 order. The total index of the diversity in the river Empayang Kasap Sukajadi Lahat district was of 2.09 to 2.46. The highest levels of diversity found in the station V (2.46) and the lowest at station I (2.09). While the value of dominance index (C) with a range of 0.17 to 0.26 at five stations in the lower state, the highest level of dominance index at station I (0.26) and the lowest at station III (0.17). River water quality conditions greatly affect the existence of gastropods.

Water quality is the key of environmental concern because of its important provision of water for drinking and domestic purpose, irrigation and aquatic life including fish and fisheries. The present study was conducted to assess the surface water quality of the Shitalakhya River from January, 2017 to December, 2018. Temperature, pH, EC, TDS, TSS, BOD5, Alkalinity, Total Hardness, Calcium Hardness, Magnesium Hardness, Chloride, Dissolved Silica, Total Iron concentration and Turbidity in water samples have been found in the ranges 24 - 33°C, 6.5 - 7.6, 108 - 478 µS/cm, 54 - 245 ppm, 8 - 118 mg/l, 6 - 12 mg/l, 36.6 - 231.8 mg/l, 30 - 190 mg/l, 20 - 120 mg/l, 10 - 80 mg/l, 3.54 - 9.91 mg/l, 16 - 51 mg/l, 0.10 - 1.5 mg/l, 2.09 - 120 NTU in the year 2017 and 21 - 32.5°C, 6.7 - 7.3, 101 - 424 µS/cm, 55 - 212 ppm,  10 - 154 mg/l, 7 - 16 mg/l, 42.7 - 219.6 mg/l,  35 - 180 mg/l, 25 - 115 mg/l, 10 - 70 mg/l, 4.96 - 16.99 mg/l, 19 - 84 mg/l, 0.10 - 2.50 mg/l, 2.73 - 214 NTU in the year 2018 respectively. Obtained results of the present study area shows that most of the parameters were within the permissible limit except Turbidity, Total Suspended Solid (TSS), Dissolved Silica (SiO2) and Biological Oxygen Demand for five days (BOD5). Use of river water can pose serious problems to human health and aquatic ecosystem via biological food chain. The present research suggests special preference for better management of the river water to protect the health of aquatic ecosystem of the river.

Potential Of Phosphate and Nitrogen Compounds in Pollution of The Upper Ciliwung River in Bogor River is a habitat for various types of aquatic organisms that can provide an overview of the state of the river, such as the quality and quantity of ecological relationships that occur within it. Ciliwung is one of the rivers that flow to Jakarta via Puncak, Bogor Regency, Bogor City, Depok City and empties into the Bay of Jakarta. In 2015, the quality status of the upstream Ciliwung river had moderate polluted status. One parameter for reviewing water quality is nutrient content (phosphate and nitrogen). The presence of high nutrients can stimulate the growth of algae in waters that can harm the aquatic ecosystem. This study shows that there is a relations and positive relations with a correlation coefficient of 0.508 on the nitrogen and phosphate compounds in the upstream Ciliwung river water pollution. The concentration of nitrogen compounds is higher than that of phosphate.Keywords: Ciliwung, Nitrogen, Phosphates, River, Relations. ABSTRAK Sungai merupakan suatu habitat bagi berbagai jenis organisme akuatik yang dapat memberikan gambaran mengenai keadaan sungai, seperti kualitas dan kuantitas dari hubungan ekologis yang terjadi didalamnya. Sungai Ciliwung merupakan salah satu sungai yang mengalir kearah Jakarta melalui Puncak, Kabupaten Bogor, Kota Bogor, Kota Depok dan bermuara ke Teluk Jakarta. Pada tahun 2015, status mutu sungai Ciliwung bagian hulu memiliki status tercemar sedang. Salah satu parameter peninjauan kualitas air adalah kandungan zat hara (fosfat dan nitrogen). Keberadaan zat hara yang tinggi dapat menstimulasi ledakkan pertumbuhan algae di perairan yang dapat merugikan ekosistem perairan. Penelitian ini menunjukkan bahwa adanya hubungan yang sedang dan positif dengan koefisien korelasi sebesar 0,508 terhadap senyawaan nitrogen dan fosfat pada pencemaran air sungai Ciliwung bagian hulu. Konsentrasi senyawaan nitrogen lebih tinggi dibandingkan dengan fosfat.Kata kunci: Ciliwung, Nitrogen, Fosfat, Hubungan, Sungai.

Abstract The structure of public water supply in Germany and the water resources used are briefly described. An overview over the legal requirements for drinking water is given, and the sources for contaminants are outlined. Then the multiple-barrier approach is discussed with respect to the resources groundwater and spring water, lake and reservoir water, and river water. Examples for treatment schemes are given and the principle of subsurface transport of river water as a first treatment step is described.

Organic Removal

A mathematical model is proposed to predict the removal of dissolved organic substances and the consumption of dissolved oxygen by attached biofilms in an open-channel flow. The model combines the biofilm equations with the conventional Streeter–Phelps type equations of river water quality by considering the mass transfer of organics and oxygen in the river water through the diffusion layer into the biofilm. It is assumed that the diffusion and reaction within the biofilm are of steady-state, and follow Monod kinetics. The model is solved numerically with a trial-and-error method. The simulation results of the model for an ideal case of river flow and biofilm show that the organic removal rate and oxygen consumption rate caused by the biofilm are greater than that by suspended biomass. The effects of diffusion layer thickness, flow velocity, and biofilm thickness on the change of river water quality are discussed.
