  • 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 ...

  • The quick and easy solution for pond leaks

    Are you tired of trying to fix that pond leak. Tried product after products For over 30 years ponds and fountains have been coated with epdm liners and have been seen as the only solution for pond repair. Many people are not aware that there is a liquid version of epdm rubber that has been specially formulated for fish friendly ponds. This one coat application has been the solution for thousands ...

  • 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. ( ...

  • 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 ...

  • Digestion of wastewater pond microalgae and potential inhibition by alum and ammoniacal-N

    Algae are produced in considerable quantities in oxidation ponds, and may negatively affect receiving waters when discharged at high concentration. Thus in some instances they require removal prior to effluent discharge, which may be enhanced using flocculants such as alum. Harvested algal biomass could be anaerobically digested to methane for use as a renewable energy source, however, alum, has ...

  • Mixed Oxidant Replaces “Cocktail” of Chemicals in Power Plan

    Cooling Tower Water Systes Synopsis In 2010 NIPSCO installed two MIOX RIO Mixed Oxidant Solution (MOS) chlorine generator systems on two of the four cooling towers at R.M. Schahfer Generating Station.  After switching to MIOX for cooling tower water treatment, the two towers experienced minimized algae growth, better biocontrol and lower Legionella counts, ...

  • Evaluation Of Moving Bed Biofilm Reactor Technology For Enhancing Nitrogen Removal In A Stabilization Pond Treatment Plant

    The Sanitation Districts of Los Angeles County (Sanitation Districts) operate the Palmdale Water Reclamation Plant (WPR) to provide wastewater treatment and disposal services for a city of 140,000. The Palmdale WRP is a secondary treatment system that uses oxidation ponds for BOD stabilization. Partial removal of nitrogen occurs within the facility, primarily as a result of assimilation by algae ...


  • Protective role of dietary N‐acetylcysteine on the oxidative stress induced by cylindrospermopsin in tilapia (Oreochromis niloticus)

    Cylindrospermopsin (CYN) is a toxin produced by various cyanobacteria species. Fish can be exposed to this cyanotoxin in their natural environments and in aquaculture ponds, and toxic effects can be derived. The present study investigated the effects of dietary N‐acetylcysteine (NAC) on the oxidative stress induced by pure CYN and CYN from lyophilized cells of Aphanizomenon ovalisporum in tilapia ...

  • Geochemical modelling of the evolution and fate of metal pollutants arising from an abandoned gold mine tailings facility in Johannesburg

    Analytical techniques were combined with geochemical modelling to study the release mechanisms of pollutants from an abandoned gold mining tailings storage facility near Johannesburg. Inverse modelling of sampled tailings pond water and experimental single extractions using various solutions indicated which combination of naturally occurring leaching solutions were likely to give rise to the ...

  • Sulfide Tails Management Within the Framework of Sustainable Development in Mineral Sand Mines—The Case Study of Sierra Rutile Ltd.

    The study discussed here assessed Sierra Rutile Ltd.’s (SRL’s) water-cover sulfide tails management method. Monthly and quarterly water samples from SRL’s Sulfide Tails Pond (STP), Total Tails Pond (TTP), and the Titan Domestic Pond (TDP) were analyzed for 15 months. Results indicated acceptable quality for the STP. From Student’s t-test analysis, it was found that the ...

  • Solar disinfection and lime stabilization processes for reduction of pathogenic bacteria in sewage effluents and biosolids for agricultural purposes in Yemen

    Yemen is the least advanced country among Middle Eastern countries in sewage reuse and safety control. The current sewage effluent quality in Yemen is generally poor as none of the existing sewage treatment plants produces effluents that comply with the effluent quality regulations. There is no plan to build tertiary treatment systems. However, the oxidation and stabilization ponds are ...

  • Olive Processing

    Problem: The aerated ponds were producing a foul odor & the chloride content of the aquifer was increasing to a level endangering the water quality. Solution: A Hydrocal CAF system is installed to treat the pit water only. This stream, which aligns the olives to be pitted, is highly contaminated with oil, grease, and ruptured olive tissue. The separate ...

  • Linking sanitation and wastewater treatment (WST)

    In both developed and developing countries, centralised and on-site wastewater treatment systems have been developed for a long time. The main function of the wastewater treatment plants (WWTPs) should be removal of pollutants including organic carbon, nitrogen and phosphorus. Technologies applied to WWTPs are mostly with biological functions such as activated sludge, stabilization reservoir, ...

  • Solar photo-catalytic treatment of textile wastewater for biodegradability enhancement

    The objective of our study was to increase the biodegradability of actual industrial (textile) wastewater using solar photo catalysis. Live industry effluent was taken and characterised. The results showed that wastewater is non-biodegradable in nature besides having an intense colour. The effluent was treated using titanium dioxide as a photo catalyst in a shallow pond slurry type reactor. The ...

  • 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 ...

  • Achieving Stringent Effluent Limits Takes a Lot of Energy!

    Enforcement of increasingly stringent effluent limits, and application of more sophisticated treatment processes for reduction of chemicals of potential concern, increases the energy consumed in municipal wastewater treatment processes. Energy consumption factors (ECFs) have been developed for wastewater treatment plant configurations based on the quantity of electrical energy used per cubic ...

  • Linking sanitation and wastewater treatment: From evaluation on the basis of effluent pollutant concentrations to evaluation on the basis of pollutant removal efficiencies

  • Biological decolourisation of simulated azo dye in aqueous phase by algae Spirogyra species

    Biological decolourisation of two azo dye effluents (direct and reactive dye) were investigated using a commonly available green algae Spirogyra sp. in viable form. Batch studies revealed the potential of algal species in removing the dye colour and dye removal was dependant on initial algal inoculum, concentration and application class of the dye. Maximum dye uptake was noticed on the third day ...
