  • Case study - California vineyard improves sludge movement with aeration

    Overview A California vineyard was faced with the challenge of meeting wastewater treatmentcompliance under a tight deadline defined by local regulators, while receiving ongoingodor complaints from the community. Challenges Extended periods of mismanagement from previous owners left the facility and the wastewater treatment system in disarray. ...

  • 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 ...

  • Is Water RunOff Effecting my Pond?

    What is Water RunOff? Runoff is precipitation that did not get (infiltrated) absorbed into the soil, or did not evaporate, and therefore made its way from the ground surface into places that water collect. Runoff causes erosion, and also carry chemicals and substances on the ground surface along to the ponds, lakes and rivers where the water ends up. ( ...

  • The effect of aeration and effluent recycling on domestic wastewater treatment in a pilot-plant system of duckweed ponds

    Three pilot-scale duckweed pond (DP) wastewater treatment systems were designed and operated to examine the effect of aeration and effluent recycling on treatment efficiency. Each system consisted of two DPs in series fed by pre-settled domestic sewage. The first system (duckweed+ conventional treatment) was ‘natural’ and included only duckweed plants. The second system ...

  • Analysis of nitrogenous and algal oxygen demand in effluent from a system of aerated lagoons followed by polishing pond

    In this descriptive-analytical study, nitrogenous and algal oxygen demand were assessed for effluent from a system of facultative partially mixed lagoons followed by the polishing pond using 120 grab samples over 1 year. Filtered and non-filtered samples of polishing pond effluent were tested in the presence and absence of a nitrification inhibitor. Effective factors, including 5-day biochemical ...

  • The effect of aerated rock filter geometry on the rate of nitrogen removal from facultative pond effluents

    Rock filters are an established technology for polishing waste stabilization pond effluents. However, they rapidly become anoxic and consequently do not remove ammonium-nitrogen. Horizontal-flow aerated rock filters (HFARF), developed to permit nitrification and hence ammonium-N removal, were compared with a novel vertical-flow aerated rock filter (VFARF). There were no differences in the ...

  • Treating Winery Wastewater Without Ponds

    Wineries traditionally treat their wine process wastewater with aerobic (aerated) ponds to biologically degrade the biochemical oxygen demand (BOD). The treated wastewater from these ponds needs to have a BOD of 40 ppm or less (depending on the location of the winery) before the winery can discharge the water to the vineyards for irrigation. The discharge level of 40 ppm as well as the ...

  • Tracer studies on an aerated lagoon

    The city of Palmerston North, New Zealand, has two aerated lagoons as its secondary treatment facility. Interest about treatment efficiency led to an investigation into the hydraulics in the second lagoon to determine if further optimisation was viable. A tracer study using rhodamine WT was undertaken to ascertain the stimulus response output. Samples were also taken at 24 points within the ...

  • Solar septic tank aeration

    Bacteria are what enable wastewater to be treated and safely disposed off. This applies to home septic systems as well as municipal sewage treatment plants. The treatment difference between the two systems is the amounts of bacteria involved. A home septic system uses the same three types of bacteria aerobic, facultative, and obligate anaerobic. Aerobic bacteria require oxygen induced ...

  • Environmental Industrial Water & Algae Control in lagoons and ponds.

    Proven site trails and report shows a excellent reduction/removal of Microcystis and filamentous algae where we proved excellent results with ASMP-1000.A systems These ponds are characterised by large open lagoons with a fairly high residence time of water and UV exposure in the summer months. During the holding period in the open reservoirs, filamentous algae start growing ...

  • 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 ...

  • Thermal stratification - Destroyer of healthy pond and lake ecosystems

    IT is early spring in a small reservoir which supports an exclusive condominium and golf coursa development. At and near the surface of the pond, in the layer called th: epilimnion, microscopic plants and animals (phytoplarikt< in and zaoplankton) feed on each other and are fed on in turn by small fish and other animals. Wind and wave action at the surface causes oxygen from the air to be ...

  • Common Causes of Fish Kills in Your Pond

    What Killed My Fish? The first question everyone has when they notice fish floating in open water or washed up along the bank is: what killed my fish? The most common causes of fish kills are oxygen depletion, algal blooms (could deplete oxygen or be toxic), pesticide toxicity and disease. By far, the most common cause of fish kills is oxygen depletion in lakes or ...

  • Wastewater lagoons – a new aeration concept

    The use of wastewater treatment lagoons, or stabilization ponds, is a common practice for rural municipalities and industrial facilities. Through the years there have been numerous designs for these ‘sludge settling basins,’ ranging from facultative, partial aerated, and fully aerated systems. But the primary reason for these systems is to utilize relatively shallow earthen ponds, or ...
