SLUDGE & BIOSOLIDS PROCESSING RESOURCES

  • The Wastewater Treatment Plant of Barstow, California (USA), sits in a challenging geographic and demographic position on a straight line between Los Angeles and Las Vegas. Operating a biological nutrient removal system, the plant treats 2.1 million gallons of water per day and discharges into percolation ponds. Kody Tompkins is the Chief Plant Operator of the facility.

  • Conventional activated sludge treatment for wastewater is becoming increasingly problematic over time. Not only does the process require significant amounts of energy, which drives up operating expenses, but utilities are under mounting pressure from the U.S. EPA to go green. Much of that push is focused on energy efficiency. Aqua-Aerobic’s AquaNereda® Aerobic Granular Sludge technology can help overcome these issues as well as other emerging constraints.

  • Organics to energy is the pathway to recovery and one of the many steps we must take to reduce our carbon footprint while also providing additional resiliency in energy supply.

  • The engineers at a municipal wastewater treatment utility were expanding their biogas digester system and were seeking an improvement over their existing, maintenance-intensive flow metering technology. They needed to measure the amount of gas contained within a gas bag as well as the flow rate of the gases traveling from the gas bag system into a co-generation power system. 

  • Plants with Anaerobic Digestion see phenomenal performance improvements in this process when they removed rags, plastics, and inorganic solids from their digester with the Hydro-Sludge Screen from Hydro International. Learn about a few of the many wastewater treatment plants that have benefitted from cleaner sludge. Read this brochure for brief case studies of how plants have improved their overall operations as well as protected valuable process performance and capacity with the Hydro-Sludge Screen.

  • Anaerobic digestion is a critical element in a sludge management plan for wastewater treatment. Its role is to kill any pathogens in the raw sludge, produce a more desirable final product, and enhance the amount of biogas/energy generated by the process. The main issue is how best to improve the sludge quality without incurring excess costs.

  • 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.

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