In aquaculture, constructed wetland (CW) has recently attracted attention for use in effluent purification due to its low running costs, high efficiency and convenient operation,. However, less data are available regarding the long-term efficiency of farm-scale CW for cleaning effluents from inland freshwater fish farms. This study investigated the effectiveness of CW for the removal of nutrients, organic matter, phytoplankton, heavy metals and microbial contaminants in effluents from a blunt snout bream (Megalobrama amblycephala) farm during 2013–2018. In the study, we built a farm-scale vertical subsurface flow CW which connected with a fish pond, and its performance was evaluated during the later stage of fish farming. The results show that CW improved the water quality of the fish culture substantially. This system was effective in the removal of nutrients, with a removal rate of 21.43–47.19% for total phosphorus (TP), 17.66–53.54% for total nitrogen (TN), 32.85–53.36% for NH4+-N, 33.01–53.28% NH3-N, 30.32–56.01% for NO3−-N and 42.75–63.85% for NO2−-N. Meanwhile, the chlorophyll a (Chla) concentration was significantly reduced when the farming water flowed through the CW, with a 49.69–62.01% reduction during 2013–2018. However, the CW system only had a modest effect on the chemical oxygen demand (COD) in the aquaculture effluents. Furthermore, concentrations of copper (Cu) and lead (Pb) were reduced by 39.85% and 55.91%, respectively. A microbial contaminants test showed that the counts of total coliform (TC) and fecal coliform (FC) were reduced by 55.93% and 48.35%, respectively. In addition, the fish in the CW-connected pond showed better growth performance than those in the control pond. These results indicate that CW can effectively reduce the loads of nutrients, phytoplankton, metals, and microbial contaminants in effluents, and improve the water quality of fish ponds. Therefore, the application of CW in intensive fish culture systems may provide an advantageous alternative for achieving environmental sustainability.

Method Approach

The industrial sector is one of the important sector in supporting the development of a region. Utilization of land around the river that is used for industrial activities will affect the quality of river water. The river can be polluted by waste personinating from industries that operating around the river. The catchment area that used for industry, agriculture, urban development, and the use of land for making roads (gravel or footpaths) can affect the flow of surface water and sediments that it brings to the river. Waste generated from industrial activities can pollute rivers which are a source of water for daily needs and affect the development of biota in them. This can affect river water quality

Abstract The humpback grouper (Cromileptes altivelis) is one of the fishery commodities with high economic value in both local and international markets. The price of humpback grouper can reach Rp. 200,000 - Rp. 400,000 / kilogram in the local market. The humpback grouper is potentially to be developed in most coastal areas of Indonesia. The conditions of water quality have a very important role for the success of fish culture of humpback grouper. To that end, monitoring and management of water quality are necessary in fish culture. The purpose of this case study is to determine the water quality conditions on humpback grouper culture in BBAP, Situbondo. The study was conducted on 16 January until 16 February 2012. The study method use descriptive method. From the results of water quality analysis, the water in humpback grouper broodstock ponds (I1 and I2) is no smell, no colour water, temperature 26.1-30 oC, salinity 27-35 ppt, dissolved oxygen 3.3-3.9 ppm, ammonia levels <0.001-0.22 ppm, nitrite levels 0.0075-0.085 ppm, alkalinity 110-120 ppm and pH 7.94-8.18. The water in humpback grouper hatchery ponds (B1 and B2) is no smell, green colour water, temperature 26.7-29.3 oC, salinity 27-34 ppt, dissolved oxygen 2.7-3.7 ppm, ammonia levels 0.0781-0.28 ppm, nitrite levels 0.0225-3.3305 ppm, alkalinity 94-126 ppm, and pH 7.14-7.81.

A study was carried out to find out the water quality ofByramangala lake of Ramanagara district. The water quality of Byramangala lake water and ground water from bore wells situated in the area within 600 meters surrounding the lake was analyzed. The quality analysis of various parameters such as BODs, COD, DO, E-Coli, and pH, Total Dissolved Solids, Total Suspended Solids and Total Hardness were tested. In addition, the presence of metals such as Cadmium (Cd), Chromium (Cr), Lead (Pb), and Iron (Fe) in the lake water and ground water samples were tested. Results for the various tests conducted showed similar trends for both lake water and ground water. It was observed that certain parameters such as BOD5, and COD were beyond permissible limits as per the BIS standards for drinking water. A few remedial measures have been proposed that may help in mitigating the pollution in the selected project area Byramangala Lake.

Growing Population

Water shortage in South Africa is a mixture of many factors: limited and highly polluted watercourses, low rainfall, fast growing population and high evaporation rates. Many studies on watercourses have shown a decline on quality due to the ongoing pollution caused by urbanization, mining, industry, power generation, afforestation and agriculture. Given the current forecasts based on population growth versus the country’s limited water resources, it is unlikely to keep existing patterns regarding the use of water and the discharge of wastes. Predictions are also indicating that pollutants will continue to accumulate in freshwater resources independently of the population growth in South Africa. Issues associated with water quality can turn out to be worsened with environmental devastating consequences. For instance, in the agricultural sector it may lead to a drop in yields and quality for fruits and crops followed by soil contamination. It can harmfully affect the population and aquatic health. Furthermore, water quality deterioration can affect the costs related to purification processes resulting in an increased price of clean water. Human induced activities causing salinization, eutrophication, acidification, presence of pathogens in watercourses, inappropriate waste discharge practices and sewage spills are major causes influencing or deteriorating water quality in South Africa.

Irrigation Systems

Methods of irrigation are reviewed, including surface irrigation, sprinkler irrigation and drip irrigation, and the problems of these systems with regard to the quality of the water used are described. Surface irrigation does not suffer much from water quality problems, but both sprinkler irrigation and drip irrigation systems are more affected, the main problem being clogging of pumps, pipes and orifices. Clogging is usually due to a combination of suspended matter, chemical precipitation and biological growth. Current solutions through water treatment, and associated problems with this, are described, with examples given of typical strainers and filters. The key to the solution of clogging problems is a proper match between water quality of the source and within the distribution system, and the type ot treatment to be used, therefore, proper water quality monitoring is recommended. Direct granular filtration is the most preferaDle treatment process for drip irrigation systems.
