Regular time series for physical-chemical water parameters: Total suspended solids and hydrogen potential

Nymphaeion alliance vegetation is dominant floating-leaved vegetation in the Danube–Tisza–Danube hydrosystem in northwestern Serbia and comprises Nymphaeetum albae, Nymphaeetum albo-luteae, Nymphoidetum peltatae and Trapetum natantis associations. Comparative analysis of physical-chemical water parameters on localities where these – in most parts of Europe endangered and vulnerable stands – develop showed that most phytocenoses are associated with specific habitat conditions. Of the analyzed water properties, the factors that cause Nymphaeion alliance phytocenoses differentiation are primarily pH, alkalinity and COD-MnO4. Formation of the Nymphaeetum albae stands is significantly associated with the highest values of pH, COD-MnO4 and alkalinity, and the lowest nitrate, nitrite, dissolved and the total phosphorus content values, in comparison to the other studied associations. Nymphoidetum peltatae stands develop in waters characterized by the lowest pH and COD-MnO4, low alkalinity, and the highest nitrate and nitrite values in relation to the other analyzed phytocenoses. Trapetum natantis stands, on the other hand, prefer the warmer sections of the canal network, neutral pH, and the highest values of BOD5, dissolved and total phosphorus. Habitat conditions in which Nymphaeetum albo-luteae stands develop are of the widest range in comparison to other investigated phytocenoses.

The study focused on the monsoonal distribution of plankton in a rain fed partial lake inSonapur, Noakhali district, Bangladesh. Three sampling sites were chosen between Sonapur zero point andNoakhali Science and Technology University. Four groups of phytoplankton such as Chlorophyceae (11genera), Bacillariophyceae (6 genera), Cyanophyceae (6 genera) and Euglenophyceae (3 genera) andfour groups of zooplankton such as Rotifera (10 genera), Cladocera (3 genera), Copepode (2 genera) andCrustacea (2 genera) were identified. The lake was found to be organic polluted (Palmer’s algal pollutionindex value: 22.33). The average wet land zooplankton index (WZI) value of this lake was estimated 3.72means moderate water quality. During the sampling periods some important physico-chemical parameterslike temperature (29-30 ?C), pH (7.8-8.2), transparency (6.5-13.50 cm), free CO2 (8.00-12.00 mg/l), totalalkalinity (13.00-14.50 mg/l), ammonia (0.1-0.5 mg/l), nitrate (0.05-0.25 mg/l), nitrite (0.03-0.07),phosphate (0.1-0.9 mg/l), dissolved oxygen (2-3.5 mg/l) and total suspended solids (4.0×10-4-5.3×10-4mg/l) were also determined as supporting water quality statement.

Micro Irrigation

The efforts to introduce the micro irrigation system in Iran go back as far as the year 1990. The area under micro irrigation system in Iran covers about 400 000 ha and it is estimated to double (800 000 ha) during the next five years. The field performance of micro irrigation systems was studied in ten Iranian sites. Physical, chemical, and biological analyses of water samples derived from each site included pH, electrical conductivity (EC), total suspended solids (TSS), total dissolved solids (TDS), Fe, Mn, Mg, Ca, and bacterial number (BN). In this study relative emitter discharge (R), percentage of completely clogged emitters (Pclog), emission uniformity (EU), absolute uniformity emission (EUa), statistical uniformity (Us), coefficient of variation due to emitter performance in the field (Vpf), and sector emission uniformity (EUs) were evaluated. Results showed that performance of micro irrigation systems in Iran is low and poor. Average EU, Us, and Vpf values in different sites were 52.8, 61.3, and 38.2%, respectively. Most frequent problems detected in irrigation units were: inadequate working pressure, emitters clogging, and lacking farmers’ training.

The objective of the present study was to determine the diversity of phytoplankton and itsrelationship with physical-chemical water parameters of Gampong Pulot Lagoon, Leupungsubdistrict, Aceh Besar. The collecting of phytoplankton and water quality were conducted inDecember 2014. According to field assessment, there were six stations to represent the study site.We recorded 25 species of phytoplankton from class Bacillariophyceae, Dinophyceae andCyanophyceae. The abundance of Bacillariophyceae was 1202.02 ind / L classified as moderate,while Dinophyceae and Cyanophyceae were 621.13 ind / L and 208.49 ind / L, respectively,classified as low abundance. Bacillariophyceae was dominated by Rhizosolenia sp. with 26% ofcomposition. The diversity index has varied from 1,88 to 2,63 indicated as moderate value. Basedon Principal Component Analysis (PCA) showed that the physical-chemical water parameters relatedto the abundance of phytoplankton in Gampong Pulot Lagoon.Keywords: phytoplankton, lagoon, diversity, leupung

Abstract This paper presents the influence of the type of filtration beds, used in swimming pool water treatment systems, on the quality and the possibility of reuse of washings. The research covered 4 pool cycles with sand, sand and anthracite, glass and diatomaceous beds. The degree of contamination of washings was assessed on the basis of physical, chemical and bacteriological tests. The possibility of washings drainage into the natural environment was considered, and the results of the research were compared with the permissible values of pollution indicators for wastewater discharged to water or ground. A direct management of washings from the analysed filters proved impossible mainly due to the high content of TSS (total suspended solids) and free chlorine. Washings were subjected to sedimentation and then the supernatant was stirred intensively. As a result of these processes, the quality of washings was significantly improved. This allowed planning to supplement the pool water installations with systems for washings management.
