  • Managing Ponds for BOD Reduction and Odor Control

    A large number of food processors utilize ponds to treat their wastewater. Most of the time these ponds are aerobic in which they use oxygen to degrade the wastewater biological oxygen demand (BOD). Fruit and vegetables contain a high amount of simple sugars and other organic compounds that when exposed to water are released into the water stream. These organic compounds require oxygen to degrade ...

  • How do you clean a stormwater management pond?

    How do you clean a stormwater management pond (SMWP) without draining the pond first? A clean-out of the SWMP is required once every 5-15 years to remove accumulated sediments to ensure the pond continues to function as intended. Drainage of the SWMP is not always required to facilitate the clean-out. By combining the pumping and excavation into one process! New pumping technology - Dragflow ...

  • Oxygen, the fix for pond problems

    Aeration of a water feature should have three main considerations. These include preventing thermal stratification, balancing the dissolved oxygen levels throughout the water column from the sludge or benthic layer to the surface and balancing temperature levels throughout the water column. Although oxygen transfer from certain methods may be significant, the greatest amount of oxygenation takes ...

  • The ponds of Hattuša – early groundwater management in the Hittite kingdom

    From about 1650 until 1200 BC Hattuša (pronounced Hattusha) was the capital of the Hittite Empire in central Asia Minor. On the steep terrain of today's ruined city lived and worked thousands of people whose homes, cattle, tools and places of worship had to be supplied with water. The question arose regarding how water was conveyed into the large-scale ponds in the urban area. The ...

  • Seasonal size distributions of suspended solids in a stormwater management pond

    ABSTRACTThree seasonal surveys of suspended solids were carried out in an on-stream stormwater management pond, by means of a submersible laser particle size analyser. Size distributions were measured at up to 17 points in the pond, and water samples collected at the same locations were analysed for primary particles aggregated in flocs. Observed suspended solids were mostly composed of flocs, ...

  • Management and treatment of landfill leachate by a system of constructed wetlands and ponds in Singapore

    Lorong Halus, Singapore's first landfill leachate treatment system, consists of a pre-treatment system (8,000 m2), five constructed reed beds (38,000 m2), five polishing ponds (13,000 m2), an education centre and a learning trail for visitors. Eight species of wetland plants (total 160,000 plants) were selected for their ability to uptake nutrients, tolerance to low ...

  • Benefits of a BaySaver Separation System for Wet Pond Pretreatment

    There are instances when a BaySaver Separation System may be used as a pretreatment device for a wet pond; when environmental regulations require it; or when a stand alone physical separator is not enough to meet an 80% removal efficiency using solely this product. There are cost benefits associated with using BaySaver products in conjunction with other Best Management Practices (BMPs). In the ...

  • Pilot plant study for one year: water quality management and algal control of sustainable urban stormwater ponds

    Pond structures as cost-effective "source control" drainage techniques that can be applied to reduce the risk of downstream flooding and to recycle stormwater. There are no widely accepted performance and water quality management data on stormwater ponds, yet there is a need for operation and maintenance guidelines, coupled with data on reliability, economics and public acceptance. The purpose of ...

  • Regulations concerning natural swimming ponds in Europe: considerations on public health issues

    Natural swimming ponds (NSPs) are a new type of recreational water facility characterized by the substitution of traditional disinfection with biodepuration. While this feature meets esthetic desires of users, specific concerns on public health issues have been raised by the scientific community and local authorities. The absence of a European directive applicable to these environments leaves ...

  • Optimization of pollution control performance of wet detention ponds in tropical urban catchments using particle swarm optimization

    Wet detention ponds are the best management systems for the control of urban stormwater. The objective of this study is to develop optimum pollution control performance of wet detention ponds using an analytical probabilistic model (APM) and particle swarm optimization (PSO). An urban catchment, in a tropical region, was selected as a case study and APM parameters were developed using long-term ...
