With rectangular, 1,000 square meter ponds and an intensive stocking density of 150 shrimp per m2, the farm demands an adequately mixed and oxygenated aquatic environment to ensure productivity and biosecurity. Mr. Rustam, the farm ...

  • Effects of scale and Froude number on the hydraulics of waste stabilization ponds

    This paper presents the findings from a series of computational fluid dynamics simulations to estimate the effect of scale and Froude number on hydraulic performance and effluent pollutant fraction of scaled waste stabilization ponds designed using Froude similarity. Prior to its application, the model was verified by comparing the computational and experimental results of a model scaled pond, ...

  • Prospects of pond ecosystems as resource base towards community based adaptation (CBA) to climate change in coastal region of Bangladesh

    Climate-induced hazards are adversely affecting the pond ecosystems in Bangladesh. Most of the poor communities collect water from isolated ponds for drinking and other domestic needs. This paper explores how the small pond ecosystems and associated livelihoods of the coastal communities are vulnerable and argues that the pond ecosystem can be a potential resource base for community based ...

  • Extracellular polymeric substance production in high rate algal oxidation ponds

    Integrated algal pond systems (IAPSs) combine anaerobic and aerobic bioprocesses to affect sewage treatment. The present work describes the isolation and partial characterisation of soluble extracellular polymeric substances (EPSs) associated with microalgal bacterial flocs (MaB-flocs) generated in high rate algal oxidation ponds (HRAOPs) of an IAPS treating domestic sewage. Productivity and ...

  • Wastewater pond systems using chemical precipitation (fellings dams): state of the art in Sweden

    Chemical precipitation in wastewater stabilization ponds – in Scandinavia called fellings dams – has been in operation for more than 50 years. Slaked lime and aluminium salts are the most common chemicals used for precipitation. Long and narrow forms of the ponds and a detention time of at least 5 days have shown, even at a low water temperature and below an ice cover, to produce an average ...

  • Control Algae and Improve the Water Quality in Waste Stabilization Ponds

    Due to population growth, accelerated urbanisation and economic development, the quantity of waste water generated is increasing globally. Mainly in low-income areas, a large proportion of the waste water is discharged directly in the environment. When the waste water is treated, the treatment plants may not remove certain pollutants that can have a negative impact on the people and ecosystem. ...

  • Effective natural organic matter removal in pond water by carbon nanotube membrane with flocculation/adsorption

    A carbon nanotube (CNT) ultrafiltration (UF) membrane was applied to natural organic matter (NOM) removal in pond water treatment. The source water was pretreated by flocculation and/or adsorption prior to the UF process to alleviate permeate flux decline and improve NOM removal efficiency. The performance of a commercial polyethersulfone (PES) UF membrane was compared to evaluate that of the ...

  • PMMA-titania floating macrospheres for the photocatalytic remediation of agro-pharmaceutical wastewater

    Antibiotics such as tetracycline are used on a large scale in agriculture, and can become concentrated in wastewater lagoons that are used in conjunction with confined animal feeding operations. Solar-illuminated titanium dioxide can be used to photocatalytically degrade aqueous tetracycline, but its application in a lagoon environment requires that the photocatalyst be supported on a ...

  • Build your pond to last with a liquid liner

    Build a pond without providing proper sealing and you'll probably be watching your money getting washed down the drain. Pond cracks, pond holes and pond leaks can be a persistent and costly problem so heading them off before they start in the construction process is a very good idea. That means paying particular attention to lining your ...

  • Make pond repair a snap with PondPro

    Pond repair can be labor intensive, costly and frustrating. If you've ever experienced that sinking feeling when you realize that the water level in your pond is steadily decreasing, you know what a hassle repairing leaks can be. For most pond owners, it brings up visions of buying a liner and hoping it will fit and will provide the coverage you need and perhaps repeating the process more than ...

  • A new methodology for surcharge risk management in urban areas (case study: Gonbad-e-Kavus city)

    This research presents a simulation-optimization model for urban flood mitigation integrating Non-dominated Sorting Genetic Algorithm (NSGA-II) with Storm Water Management Model (SWMM) hydraulic model under a curve number-based hydrologic model of low impact development technologies in Gonbad-e-Kavus, a small city in the north of Iran. In the developed model, the best performance of the system ...

  • Effect of baffles on the hydraulic performance of sediment retention ponds

    An investigation of the effect of baffles on retention pond performance using a physical model of an existing sediment retention pond is presented. Analysis of residence time (RTD curves) was used to compare the hydraulic performance of different arrangements of baffles in the pond. Five different arrangements for the design of baffles were studied. The results show that placing a single ...

  • Effects of silver nanoparticles to the freshwater snail Physa acuta: The role of test media and snails' life cycle stage

    Silver nanoparticles (AgNP) are highly used worldwide, which will most likely lead to their release to the environment and subsequently increase environmental concentrations. Therefore studying AgNPs' deleterious effects to organisms is crucial to understand their environmental impacts. The freshwater snail Physa acuta was chosen to evaluate the potential deleterious effects of AgNP and ...

  • Can’t Afford Pond Dredging? We have solutions.

    Ponds and lakes naturally accumulate sludge and nutrients that lead to eutrophication and eventually pond or lake death. Natural succession is driving all lakes and ponds to become meadows and eventually forest. To slow or reverse this process and maintain a lake or pond beneficial microbes are critical. These beneficial microbes improve water quality by reducing nutrients and sludge through ...

  • Ultrasonic algae control solutions to treat smaller water areas

    Algae has an import function in nature, it provides food and energy for animal life, and much of the earth’s oxygen. However, an excess of algae can be hazardous to both humans and animals. Research has demonstrated that ultrasound can be an effective method of controlling algal blooms. Ultrasonic algae control solutions: the differences There are various ...

  • Polishing of treated palm oil mill effluent (POME) from ponding system by electrocoagulation process

    As the ponding system used to treat palm oil mill effluent (POME) frequently fails to satisfy the discharge standard in Malaysia, the present study aimed to resolve this problem using an optimized electrocoagulation process. Thus, a central composite design (CCD) module in response surface methodology was employed to optimize the interactions of process variables, namely current density, ...

  • Development of Helisoma trivolvis pond snails as biological samplers for biomonitoring of current‐use pesticides

    Non‐target aquatic organisms residing in wetlands are commonly exposed to current‐use pesticides through spray drift and runoff. However, it is frequently challenging to measure exposure due to rapid dissipation of pesticides from water and reduced bioavailability. Our hypothesis is that freshwater snails can serve as bioindicators of pesticide exposure based on their capacity to passively ...
