  • Treating Your Water with a Biological Filtration System

    Poor-quality drinking water can be an enormous hazard to your health. News stories in recent years have reported experiences of unfortunate individuals who have unknowingly consumed tainted or otherwise unsafe drinking water that included high levels of lead, calcium, arsenic, and other chemicals that have serious negative health effects. Before you take another sip of your water supply, consider ...

  • Water treatment plant sludge disposal into stabilization ponds

    Researchers have paid particular attention to the disposal of sludge produced in water treatment plants (WTPs) into wastewater treatment plants (WWTPs) for further processing, mainly because it is considered an attractive alternative for the treatment of waste generated in water production processes. This study evaluated the effects of flow equalization and disposal of sludge, from a ...

  • What Limits the Productivity of Acid Mine Drainage Treatment Ponds?

    Acid mine drainage (AMD) treatment ponds are very common in the U.S. Appalachian coal region and are the main source of many headwater streams. Though the water that discharges from these ponds generally meets state and federal water quality standards, there is a distinct lack of productivity in most of these ponds. Our first objective was to compare the productivity of chemically-treated, ...

  • Treatment of denis pond woluwe park brussels, Belgium case study

    Executive Summary As a result eutrification (the process in which oxygen is removed from the water by the decomposition of large amounts of organic matter) the water quality in the Denis Pond in Woluwe Park, Brussels, Belgium began to deteriorate in the 1960’s and accelerated in the 1970’s. This eutrification resulted in a reduction in water transparency, an increase in the ...

  • Characterization of methane flux from photosynthetic oxidation ponds in a wastewater treatment plant

    Photosynthetic oxidation ponds are a low-cost method for secondary treatment of wastewater using natural and more energy-efficient aeration strategies. Methane (CH4) is produced during the anaerobic digestion of organic matter, but only some of it is oxidized in the water column, with the remaining CH4 escaping into the atmosphere. In order to characterize the CH4 flux in two ...

  • Odorous compounds treatment of winery and distillery effluents during natural evaporation in ponds

    ABSTRACTDuring treatment of winery and distillery wastewater by natural evaporation in ponds, formation of malodorous compounds induces harmful olfactory effects. In this work, we studied the origin of malodorous compounds and methods to prevent and treat odours. The formation of volatile fatty acids (VFA) from pure substrates (glycerol, lactic and tartaric acids, ethanol) and complex media ...

  • Upgrading of decentralized ponds for municipal wastewater treatment and restricted reuse

    Upgrading of a pond system for municipal wastewater treatment in a decentralized area is evaluated. The pond was constructed for the treatment of 63 m3/d. Currently it receives 83 m3/d, therefore poor treatment efficiency was recorded. An expansion of 1.6 times the present land area was required. In addition to construction, operation and maintenance were required to meet the permissible limits. ...

  • VSEP filters mine tailing pond effluent with no pre-treatment required

    New Logic International installed its Vibratory Shear Enhanced Processing (VSEP) system in March, 1998 at a major California rare earth mining and manufacturing facility. The VSEP is used for treatment of mine tailing pond effluent at this facility with no pretreatment required. The VSEP system uses nanofiltration followed by ultrafiltration membrane modules and is able to treat the mine tailing ...

  • Algal biofuels from wastewater treatment high rate algal ponds

    This paper examines the potential of algae biofuel production in conjunction with wastewater treatment. Current technology for algal wastewater treatment uses facultative ponds, however, these ponds have low productivity (∼10 tonnes/ha.y), are not amenable to cultivating single algal species, require chemical flocculation or other expensive processes for algal harvest, and do not provide ...

  • 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 ...

  • Performance studies on constructed wetland for treatment of crocodile pond wastewater

    Crocodile pond wastewater has high Biochemical Oxygen Demand (BOD5) (100 mg/L), phosphorus (6 mg/L) and nitrogen (30 mg/L). In the present study a Vertical Flow (VF) constructed wetland treatment system planted with Arundo donax was employed to achieve the wildlife discharge standards (BOD5 ...

  • Disinfection capacity of seven constructed wetlands and ponds

    The disinfection performance of three subsurface flow constructed wetlands (SSF), a free-water surface-constructed wetland and three ponds were investigated. They functioned as advanced treatment stage following treatment in a large municipal wastewater treatment plant equipped with nutrient removal. Despite low influent concentrations of 103.9/100 mL, Escherichia coli underwent a ...

  • Case Study: Farm pond sludge and algae remediation

    Problem A 1 ½ acre farm pond located in southeastern Wisconsin was experiencing a severe algae bloom due to high levels of fertilizer runoff from the surrounding farm fields located on the north and east sides of the pond. Farm field runoff drains into the north end of the pond via a 4-inch drainpipe. The pond is further fertilized by the year round population of 6-8 resident ducks and by ...

  • 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 ...
