SLUDGE & BIOSOLIDS PROCESSING RESOURCES

  • In 2001, when KLa designed its first aeration system, the two most prevalent biological wastewater treatment options were sequencing batch reactor (SBR) and conventional activated sludge (CAS) processes. Today’s options are much broader. Yet, cost-efficient aeration still remains an underlying challenge. This Q&A article provides a look at how the industry arrived at today’s opportunities and where it’s headed for the future.

  • Pablo Garcia, Global Business Development Manager at Sulzer, looks at how tunneling operations can be affected by the choice of pumping equipment used for dewatering.

  • The Littleton / Englewood Wastewater Treatment Plant, just south of Denver, is the third largest publicly owned treatment works in the state of Colorado. It receives sewage from the cities of Littleton and Englewood, as well as 21 connector districts in a 75-square-mile service area. Farmer’s staff chose to implement an upgraded grit removal system supplied by Hydro International. Two complete HeadCell® systems were implemented – each consisting of one HeadCell® grit separation unit, one SlurryCup™ grit washing unit, and one Grit Snail® grit dewatering escalator.

  • Biological treatment processes are an important component in many wastewater treatment systems. They are one of the most efficient and effective ways of reducing organic material in wastewater. There are quite a few of them that have been researched and used over several decades. However, one of the most widely used conventional biological treatment process is the activated sludge process (ASP). Many sewage treatment plants use ASP in their secondary treatment steps due to the human and animal organic matter in the inlet waters of wastewater treatment plants.

  • A moving bed bioreactor is a biological sewage treatment process. In many instances, wastewater is full of organic matter that can be difficult to filter out by physical or chemical means. Thus, one of the best methods of dealing with organic matter is treating it with a biological process. The basic idea behind biological water treatment processes is using micro-organisms to break down sewage.

  • Officials at the Jefferson Parish Sewerage Department approached the team at Digital Engineering to find a long-term solution for the odor and corrosion issues throughout the East Bank Wastewater Treatment Plant. The consultants at Digital Engineering, headquartered in Kenner, La., began researching methods to reduce odor and corrosive compounds flowing into the plant while also protecting the parish’s infrastructure from the harmful effects of hydrogen sulfide (H2S). Because expensive chemicals fail to prevent the occurrence of H2S, plant consultants opted to use oxygen to minimize corrosion while reducing chemical costs.

  • Plant officials at a 12 MGD wastewater plant in Arkansas began evaluating disinfection alternatives to upgrade their current system as well as address the removal of contaminants of emerging concern (CEC). The facility, which included primary clarification, activated sludge, secondary clarification and sand filtration, elected to use dissolved ozone to replace its current ultraviolet (UV) system. After researching different ozone systems, plant officials chose to install BlueInGreen’s HyDOZ® technology in order to more efficiently meet current permit requirements, as well as prepare for future legislation.

  • The Central Valley Water Reclamation Facility was built in 1988 and serves a total population of over 550,000 in Salt Lake County. Central Valley’s entire property covers 168 acres (0.7 km) with the treatment facility using 85 acres. The facility has over 80 dedicated employees and treats a peak daily flow of 85 Mgal/d (3724 L/s). In 2009, one of the two existing sludge screens was replaced with the Hydro-Sludge® Screen manufactured by Hydro International. The replacement unit was installed with little modification to the existing piping and support structure. The unit has been in operation with exceptional results.

  • For best results, match the system with the jobsite conditions.

  • Inspired in part by California’s Senate Bill 1383, which was enacted to reduce organic waste and methane emissions, co-digestion is fulfilling those goals while converting wastewater treatment plants into water resource recovery facilities.

  • Sludge handling presents a growing set of challenges for municipal and industrial wastewater operators, who are increasingly turning toward a natural solution. This alternative method results in a reduced biosolids load that lowers hauling and tipping fees, reduces process energy costs, cuts down odors, and fosters the natural cleaning of pipes and fittings.

  • Lower tipping and hauling fees, plant and site odor, processing times and more for the waste industries.

  • Natura Solve provides a complex liquid medium that is produced via a proprietary fermentation process. It consists of a selected spectrum of naturally occurring microorganisms, sustained within a matrix of micro elements and macro elements that provide the critical building blocks for respiration and growth. Thus it simultaneously works as both a biocatalyst, stimulating endogenous bacteria metabolic and production rate and a specialized delivery medium for the highly effective bacteria. The formula is very aggressive due to the essential balance between the selected groups of microorganisms, which, when combined with the enzymes they produce, synergistically create catalyzing proteins that significantly speed up the biochemical reactions and natural decomposition processes of the organic material into humic matter.

  • Increasing profitability through efficient tailing and pregnant solution processing.

  • IGNITE™ Integrated Nitrification Process

    The IGNITE™ Integrated Nitrification process is a non-activated sludge solution for upgrading lagoon based treatment plants to achieve improved BOD and ammonia removal. The process utilizes a combination of Parkson’s Biofuser® lagoon aeration system and the TumbleOx™ Nitrification Reactor process.

  • TumbleOx™ Nitrification Reactor

    The Parkson TumbleOx™ Bioreactor consists of a treatment tank(s) containing a series of slowly rotating drums. Each drum is partially filled with loose media which freely tumbles inside the five-foot diameter drum as it rotates. A thin biofilm grows on the media and provides biological treatment. The unique media design maximizes surface area for biological growth and also aerates the wastewater as the drum turns, providing dissolved oxygen for the micro-organisms. The system components include the rotating drum, plastic media, and the bearings and simple drive mechanism to slowly rotate the drum. No supplemental aeration system is required.

SLUDGE AND BIOSOLIDS PROCESSING VIDEOS

The Hycor® Helisieve® M In-Channel Fine Screen provides liquid-solid separation for wastewater treatment. This heart of the system is a heavy-duty shaftless spiral with brush that conveys screenings to a dewatering zone for discharge. Because the unit is shaftless, it handles a greater volume of solids and easily conveys stringy solids.
