  • Treatment plants specially designed for cold climates provide a solution for two seasonal cabin complexes in Denali, Alaska

    Grizzly Bear Cabins and Campground in Dcnali, Alaska, needed a larger onsite system to handle a major expansion. Across the road, the undersized system for Dcnali River Cabins complex also needed replacement. Bio-Microbics engineer Reza Shams, Ph.D. helped design engineer Bob Tsigonis, PE., owner of Lifewater Engineering Co. in Fairbanks, to address numerous challenges. Both properties had ...

  • 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 ...

  • Contaminant removal in septage treatment with vertical flow constructed wetlands operated under batch flow conditions

    Individual septic tanks are the most common means of on-site sanitation in Malaysia, but they result in a significant volume of septage. A two-staged vertical flow constructed wetlands (VFCWs) system for the treatment of septage was constructed and studied in Sarawak, Malaysia. Raw septage was treated in the first stage wetlands, and the resulting percolate was fed onto the second stage ...

  • Application of nano-silver coated granular activated carbon for inactivation of septic tank effluent

    On-site sanitation systems such as cesspools and septic tanks are widely used in most developing countries. These systems primarily aim to collect and treat toilet wastewater or blackwater. Although septic tanks are commonly used in non-sewered areas, their effluents are still rich in pathogens and other pollutants. The practice of direct discharge of septic tank effluents into the surrounding ...

  • 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 ...

  • The use of palm kernel shell (PKS) as substrate material in vertical-flow engineered wetlands for septage treatment in Malaysia

    In this study, the treatment of septage (originating from septic tanks) was carried out in a pilot-scale, two-staged, vertical-flow engineered wetland (VFEW). Palm kernel shells (PKS) were incorporated as part of the VFEW's substrate (B-PKS), to compare its organic matter (OM) and nitrogen (N) removal efficiency against wetlands with only sand substrates (B-SD). The results revealed ...

  • 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 ...

  • Enhanced nitrogen removal with an onsite aerobic cyclic biological treatment unit

    Coastal Zone Act Reauthorization Amendments (CZARA, Section 6217) necessitate the requirement that onsite wastewater disposal units located near impaired surface waters or groundwater to provide at least 50% nitrogen removal. Approximately 38% of Hawaii households use onsite systems including septic tanks and cesspools that cannot meet this requirement. Upgrades to aerobic ...

  • Southside, Arkansas - Case Study

    Rural area faced failing septic tanks in soggy land that didn't perc well. The Problem Failing septic tanks needed to be replaced. Gravity sewers were cost-prohibitive, requiring deep trenches and massive disruption. The Solution E/One's grinder pump stations easily replaced septic tanks. Improving the infrastructure was required in order to spur ...

  • Evaluating the effects of septic tank on shallow wells in Iba housing estate, Ojo LGA, Lagos

    Water samples from 30 shallow wells were measured for depth, depth to water table, and distance to septic tank. In situ parameters including electrical conductivity, pH, total dissolved solids, and temperature were measured using portable meters. Chemical parameters including salinity, chloride, calcium, alkalinity and total hardness were determined using titrimetry method. Sulphate and nitrate ...

  • KSFA Info-FLO: “Better than New Septic from Bio-Microbics!“

    Better than New Septic from Bio-Microbics! In Western Kansas, those properties that experience biologically-failed septic systems rarely have options other than to replace the entire system - an expensive endeavor for low-income housing. For a family located in Finney County, the local authorities identified the tell tale signs of a biological failure ...

  • Drain Cleaning Does Not Require Digging Anymore

    The professionals at Lake Norman Septic use cable snakes and other tools to locate your septic issue and unclog any drains and pipes. Before these techniques existed a septic tank issue often meant intensive digging and weeks of messy yard waste. The new cable snakes use tiny cameras than can easily squeeze through your sewer and septic ...

  • New Home with Puraflow Septic System and Odor Complaint - Case Study

    Problem After installation of a Puraflow septic system the customer complained of odors in his yard. The contractor installed residential vent odor filters on the tank vent on the roof vents. The residential odor filters improved but did not eliminate the problem. The contractor reviewed the problem with Simple Solutions and determined that the problem was due to the ...

  • Retainment of the antimicrobial agent triclosan in a septic tank

    Laboratory experiments were conducted to investigate the fate of the antimicrobial agent triclosan (TCS) in a conventional septic tank. The main mechanism of TCS removal from wastewater was identified to be rapid TCS sorption to suspended particles followed by settling of these particles to the bottom of the septic tank. Sorption to particles was completed within minutes while the settling took ...

  • 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 ...

  • Organic matter and nitrogen removal at planted wetlands treating domestic septage with varying operational strategies

    A two-staged engineered wetland-based system was designed and constructed to treat raw domestic septage. Hydraulic loading rates (HLRs) of 8.75 and 17.5 cm/d were studied with four and eight daily dosings at the second stage of the system to investigate the influence of the regimes on septage treatment. Removal of organic matter (OM) was found to be HLR dependent, where the results indicated ...

  • 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 ...
