  • A Four Channel Gas Detector for Wastewater Treatment Plants

    Common hazardous gases found in wastewater treatment plant facilities are hydrogen sulphide, methane, ammonia, carbon monoxide, chlorine and oxygen deficiency. Some facilities may also use ozone, chlorine dioxide or sodium hypochlorite with the chlorine during the sanitization treatment process. Furthermore, sulphur dioxide is often used to de-chlorinate the water once the treatment process is ...

  • Wastewater Treatment Plant - Newport, New Hampshire - Case Study

    THE CHALLENGE Newport, New Hampshire is a small New England community of 6000 residents. The treatment plant treats primarily residential sewerage, although Newport is home to an internationally known firearms company, which also sends its waste to the municipal plant for treatment. This 1.3 MGD plant which operates at an average of .75 MGD, was built in 1971 and upgraded in 1988 to ...

  • Struvite Formation & Struvite Wastewater Treatment

    The three chemical components for Struvite formation are magnesium, ammonia and phosphorus, also known as MAP for short. Struvite’s chemical formula is NH4MgPO4·6H2O. WWTP managers have used a number of different products and techniques for Struvite removal, and to prevent Struvite formation. Most text books on Struvite control talk about the use of ferric chloride (FeCl3) to control ...

  • Domestic wastewater treatment by a constructed wetland system planted with rice

    The experiments were conducted in four concrete laboratory scale free water surface constructed wetland units 1 m wide, 1.5 m long and 0.8 m deep. Paddy field soil was added to a depth of 0.4 m and rice seedlings (Oryza sativa L.) were transplanted into the units at a density of 25 plants/m2. Domestic wastewater collected from Chiang Mai University was applied into each unit via two different ...

  • Cost Trends of MBR Systems for Municipal Wastewater Treatment

    Cost estimates were developed for full-scale (1 and 5 MGD) MBR facilities designed to treat municipal wastewater. These estimates included both capital and operational / maintenance (O&M) costs related to the headworks, MBR process (biological process and membrane system), chlorine disinfection and effluent storage. The costs associated with the membrane systems were developed from budgetary cost ...

  • Reuse of wastewater effluent in concrete mixing and the effect of high temperatures on its residual properties

    This paper investigates the suitability of using wastewater effluent for mixing in concrete. In particular, the effect of elevated temperatures up to 700°C on the compressive strength of concrete made with treated wastewater has been experimentally studied. The concrete specimens consisted of cubes that were cast using potable water (PW), primary treated wastewater (PTWW), secondary treated ...

  • Rock Box Protects Headworks at Kansas City, Missouri Blue River Wastewater Treatment Plant

    Kansas City Missouri Water Services Department operates the 105 mgd Big Blue River Wastewater Treatment Plant (WWTP) serving combined and separate sanitary sewers on both sides of the Missouri River in Kansas City. Heavy grit inundation from the Combined Sewer System (CSS) was impacting the screen house and aerated grit/pre-aeration basins at this facility. Alternatives were considered for ...

  • Replacement of 130 ft Secondary Clarifiers at a 25 MGD wastewater treatment facility

    Challenge A municipal WWTP found that (2) of their secondary clarifiers were too rusted and corroded to properly function. A traditional clarifier refurbishment consisting of sandblasting and painting was not a viable option because one of the clarifier rake arms had recently broken due to its poor condition. The plant engineers decided that a clarifier rebuild was necessary to ensure ...

  • Case study - Heat loss - A problem for wastewater treatment & nitrification

    Problem: Operators know aerobic and anaerobic systems need sufficient water temperature to keep microbial populations active and working. Heat loss is detrimental to effluent quality and gas production. Both systems can be negatively affected from low daily and seasonal temperatures. Unfortunately, most operators and engineers have no control over water temperature loss in their tanks and ...

  • WPL’s easy to install diamond sewage treatment plant case study

    If you are lucky enough to be involved with a building project in the beautiful countryside of Great Britain, one thing you will find most properties have in common here is that they are likely to be off-mains drainage. When involved with an off-mains building project, it is important that you do know where your wastewater goes and what happens to it, usually by means of a domestic sewage ...

  • Viltra IWOX systems engineered by DMT - The next standard in small scale wastewater treatment

    Abstract Both technology and environmental awareness drive legislation for wastewater treatment. Now, the leap from 20/30 (BOD: Biological oxygen demand, mg/l / SS: suspended solids, mg/l) to 10/10 or even 5/5 is possible due to a different design approach. For years, the sewage treatment plant market was dominated by systems from (septic) tank suppliers, but now an engineering company ...
