  • Maintenance for septic tanks

    Septic tanks are widely used for on site sewage treatment for domestic homes which are not connected to the sewer system. Little attention is given to the septic tank until there are problems such as smells or poor drainage or ponding on the surface. A little maintenance of the septic tank can be very helpful in maintaining performance of the septic tank. The outflow from a septic tank percolates ...

  • Enhancement of a UASB-septic tank performance for decentralised treatment of strong domestic sewage

    The possibility of enhancing the process performance of the UASB-septic tank for treating strong sewage in Palestine by means of inoculating the reactor with well adapted anaerobic sludge and/or adding a packing media to the upper part of the reactor, creating an anaerobic hybrid (AH)-septic tank, was investigated. To achieve these objectives, two community onsite UASB-septic tank and AH-septic ...

  • Comparing the performance of prescribed septic tanks to long, narrow, flooded designs

    About 30% of all sewage generated in North America passes through septic tanks, but there is a lack of study to improve these important treatment vessels, and there is no performance-based standard. A survey of existing literature shows that septic tank effluent quality is improved in tanks designed for quiet, laminar fluid-flow and minimum ‘dead space’ such as in longer, narrower tanks. A ...

  • Taney county man works to improve septic tanks

    Taney County — Perched casually atop a ring of unearthed dirt in his back yard, Floyd Gilzow peered into a pit as two mud-covered men tinkered with his septic tank Tuesday morning. The men — employees of White River Valley Environmental Services — were retrofitting the tank with a second chamber that will incorporate oxygen into the on-site sewage treatment process. Most of the ...

  • Performance of a system with full- and pilot-scale sludge drying reed bed units treating septic tank sludge in Brazil

    This study investigated the performance of sludge drying reed beds (SDRB) at full- and pilot-scale treating sludge from septic tanks in the city of Belo Horizonte, Brazil. The treatment units, planted with Cynodon spp., were based on an adaptation of the first-stage of the French vertical-flow constructed wetland, originally developed for treating sewage. Two different operational phases ...

  • Load limit of a UASB fed septic tank-treated domestic wastewater

    Performance of a 250 L pilot-scale up-flow anaerobic sludge blanket (UASB) reactor, operated at ambient temperatures, fed septic tank effluents intermittently, was monitored for hydraulic retention time (HRT) from 18 h to 4 h. The total suspended solids (TSS), total chemical oxygen demand (CODT), dissolved chemical oxygen demand (CODdis) and suspended chemical oxygen demand (CODss) removal ...

  • Advanced Enviro - Septic™ Wastewater Treatment System Septic Tank Effluent Filters and Charco al (Odor) Filters NOT Recommended

    Abstract: Effluent filters are installed in the outlet from the septic tank with the intended purpose of retaining solids inside the tank, preventing them from entering the treatment system and/or dispersal field. The concern is that if solids escape from the septic tank, they could cause clogging of the system components or the soil interface. While this may be a legitimate concern for some ...

  • Effect of soil fortified by polyurethane foam on septic tank effluent treatment

    Fortified soil was made up of a mixture at a mass ratio 4/1000–6/1000 of sponge and natural soil according to the results of column experiment. The fortified soil had bigger porosity and higher hydraulic conductivity than the natural soil. The columns packed with 900 mm of the fortified soil endured a flow rate equivalent to 100 L/m2/d of septic tank effluent and the average chemical oxygen ...

  • Assessment of the impact of traditional septic tank soakaway systems on water quality in Ireland

    One of the key threats to groundwater and surface water quality in Ireland is the impact of poorly designed, constructed or maintained on-site wastewater treatment systems. An extensive study was carried out to quantify the impact of existing sites on water quality. Six existing sites, consisting of a traditional septic tank and soakaway system, located in various ranges of subsoil ...

  • Septic shouldn’t be a Nightmare for a Dream Home

    Problem In January of 2002, a couple in Homosassa Springs, Florida (near Orlando) had big plans for large new dream home. They had torn down their old Florida “vernacular” home design, or commonly referred to as the “Cracker Style.” They had major setbacks from the beginning due to the lot size and location; they also began construction without out the proper permits ...

  • Nitrate: AQUAMEND™ Denitrification Units (Septic Water)

    The AQUAMEND® process has proven to be successful for the treatment of a wide range of constituents of interest. Much work was performed by Adventus in the area of treatment of high-strength industrial wastewater, with concentrations as high as 3,000 mg/L NO3-N (nitrate as nitrogen). In recent years development focused on use of the technology for the treatment of nitrate from on-site treatment ...


  • Sludge accumulation and conversion to methane in a septic tank treating domestic wastewater or black water

    Although the septic tank is the most applied on-site system for wastewater pre-treatment, limited research has been performed to determine sludge accumulation and biogas production in the tank. Therefore a dynamic mathematical model based on the Anaerobic Digestion Model No. 1 (ADM1) was developed for anaerobic digestion of the accumulated sludge in a septic tank treating domestic wastewater or ...

  • Drip distribution soil performance and operations in a northern climate

    Six drip distribution systems in Wisconsin were studied to determine the treatment performance of the soil beneath the distribution network. Of the six systems studied, three received septic tank effluent (STE), one received effluent treated by a recirculating gravel filter (RGF) and the remaining two sites were treated by aerobic treatment units (ATU). Soil conditions varied at these sites, ...

  • Factors affecting the performance and risks to human health of on-site wastewater treatment systems

    Aerobic wastewater treatment systems (aerobic systems) are the preferred choice in a region overlying a karstic aquifer used for drinking water supplies, as they are thought to provide better protection to groundwater and human health than standard septic systems. However, aerobic systems in operation do not always perform to design standard; while this is often blamed on lack of maintenance, few ...
