  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Do you Have Sludge Build Up in Your Pond?

    Smelly and Muddy Water 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 ...

  • Sunlight-Blocking Covers Control Algae, Reduce Operational Costs at California Utility

    The Utility: The Santa Clara Valley Water District (the District) manages an integrated water resources system that includes the supply of clean, safe water, flood protection, and stewardship of streams on behalf of Santa Clara County's 1.8 million residents. The district effectively manages 10 dams and surface water reservoirs, three water treatment plants, an advanced recycled water ...

  • Dredge caustic and abrasive materials in South Korea-case study

    Customer: Zinc mining & processing facility, South Korea. Problem: How to remove 200,000 cubic meters of 325 mesh goethite (pH 2.2 - 2.5 range; sulfuric acid) from a lined pond with dimensions of 120m x 253m. Since the material had settled and was resting on the pond bottom, dredging was selected as the appropriate removal method. No standard acid-resistant dredge ...

  • Drinking water contributes to high salt consumption in young adults in coastal Bangladesh

    Increasing salinity of freshwater from environmental and anthropogenic influences is threatening the health of 35 million inhabitants in coastal Bangladesh. Yet little is known about the characteristics of their exposure to salt (sodium), a major risk factor for hypertension and related chronic diseases. This research examined sodium consumption levels and associated factors in young adults. ...

  • Effects of physical and morphometric factors on nutrient removal properties in agricultural ponds

    Effects of physical and morphometric factors on nutrient removal properties were studied in small agricultural ponds with different depths, volumes, and residence times in western Japan. Average residence time was estimated to be >15 days, and it tended to decrease from summer to winter because of the increase in water withdrawal for agricultural activity. Water temperature was clearly ...
