  • The Basics of Evapotranspiration

    Evapotranspiration (ET) represents the loss of water from the Earth’s surface from the combination of direct evaporation and plant transpiration. ET is usually expressed as a rate such as inches per day. Knowledge of ET is important for irrigation scheduling but it is also an important factor for other land use applications such as septic tank drain fields, watershed level budgeting, and ...

  • The Toxic Effects of Hydrogen Sulfide (H2S) Gas from Sewers on Health & Infrastructure - Case study

    How is Hydrogen Sulfide Created? Hydrogen sulfide emitted from sewers and septic tanks can cause serious health issues. Hydrogen sulfide gas is created and released into the air when waste water remains stagnant for a long period of time, and becomes depleted of dissolved oxygen. Although sewer workers are most likely to be affected by hydrogen sulfide overexposure, people living or ...

  • Sensitivity of groundwater flow with respect to the drain–aquifer leakage coefficient

    Mitigation measures may be used to prevent soil and water pollution from waste disposal, landfill sites, septic or chemical storage tanks. Among them, drains and impervious barriers may be set up. The efficiency of this technique can be evaluated by means of groundwater modeling tools. The groundwater flow and the leakage drain–aquifer interactions are implemented in a conforming finite ...

It indicates that the customers greatly prefer the hotel services to ensure a comfortable living. Mainly in the metro areas, there is a good demand for hotel services. Treated Gray water ...

  • The Flushability of Flushable Wet Wipes

    Whether used to remove cosmetics, clean a baby or wipe food and debris from the kitchen counter, a growing number of consumers are purchasing flushable wet wipes for their household needs. In fact, The Atlantic reported personal wet wipe sales reached an estimated $2.2 billion last year, and Euromonitor International’s market tracker predicts 3-percent growth in sales volume of wet ...

  • Wastewater and groundwater

    Nearly 25 percent of the population in the United States—in more than 25 million homes—disposes of wastewater through onsite, or unsewered, systems that return treated effluent to the ground. This is an important public health issue because many of those same homes use wells that rely on groundwater for the drinking water supply. With ...

  • Pump Your Waste with Kingspan Klargester

    If your project is among the 1.5 million homes and properties in the UK that cannot connect to the main sewer, what should you do? First, the 2010 Building Regulations recommends that a site visit is carried out by a suitably qualified expert before the preferred treatment option is decided upon. Kingspan Klargester product experts will provide that service totally free of charge.  And ...

  • Start-up phase of a UASB-septic tank used for high strength municipal wastewater treatment in Mexico

    The objective of this work was to assess the performance during the start-up phase of a Upflow anaerobic sludge blanket (UASB)-septic tank for municipal wastewater treatment in Mexico City. A lab scale UASB-septic tank (62 L total volume, acrylic), consisting of three chambers treated high strength municipal wastewater at ambient temperature (16 °C–24 °C), under 72 h Hydraulic retention time ...

  • Sludge Blanket Theory: Digging deeper

    With over 50 years of design and manufacturing experience, we are rightly proud of our British-built environmentally friendly SludgeWatch 715 Sludge Blanket Detector. Our user-friendly design is highly portable, simple to use and along with its low cost has worldwide appeal. Things have changed somewhat since our first Sludge Blanket Detector was made back in 1974. No more messy man-handling of ...

  • 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 ...

  • Groundwater and stream E. coli concentrations in coastal plain watersheds served by onsite wastewater and a municipal sewer treatment system

    The goal of this study was to determine if onsite wastewater treatment systems (OWS) were influencing groundwater and surface water Escherichia coli concentrations in a coastal plain watershed. Piezometers for groundwater monitoring were installed at four residences served by OWS and five residences served by a municipal wastewater treatment system (MWS). The residences were located in two ...

  • 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 ...

  • Transport of enterococci and F+ coliphage through the saturated zone of the beach aquifer

    Coastal groundwater has been implicated as a source of microbial pollution to recreational beaches. However, there is little work investigating the transport of fecal microbes through beach aquifers where waters of variable salinity are present. In this study, the potential for fecal indicator organisms enterococci (ENT) and F+ coliphage to be transported through marine beach aquifers was ...

  • 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 ...
