  • Treatment of high strength aqueous wastes in a thermophilic aerobic membrane reactor (TAMR): performance and resilience

    In the present work, the thermophilic aerobic membrane reactor technology was studied for the treatment of high strength aqueous wastes mainly containing dyes, surfactants and solvents. The thermophilic biomass resilience and the process stability under critical conditions (such as rapid rise of the mixed liquor pH, oxygen supply interruption, etc.) were also evaluated. The experimental work ...

  • Influence of the comminution of organic waste on their biodegradability

    Organic solids are present in very large quantities as products or waste from agriculture, food industry, household and many other fields. The disposal of organic waste can be realised using biological processes like anaerobic digestion or aerobic composting. The anaerobic digestion has advantages in comparison to composting such as a better handling of wet waste, the production of useful ...

  • Ultrasonic Waste and Sludge Treatment

    Biogas is generated from sources, such as municipal organic waste, sewage sludge, muck or manure. Ultrasonication improves the digestibility of such organic material leading to more biogas and less residual sludge. Biogas is a byproduct of the decomposition of organic matter by anaerobic or aerobic bacteria. It consists primarily of methane, carbon dioxide and hydrogen sulfide. This makes biogas ...

  • The role of respirometry in maximising aerobic treatment plant efficiency

    Wastewater treatment plants are coming under increasing pressure to increase their efficiency of operation. There are two objectives in this. The first is to reduce the cost of treatment. The second is a response to new legislation aimed at reducing the carryover of toxic materials to receiving waters. In order to achieve this, it is necessary to focus on the pivotal role of bacterial respiration ...

  • Performance evaluation of an aerobic biofilter with high organics containing synthetic wastewater

    The organics removal performance of a lab-scale aerobic biofilter of volume 0.6 L was studied using synthetic wastewater and waste automobile tyre-tube beads as media. The column study was performed under Chemical Oxygen Demand (COD) in the range of 500-1500 mg/L at an empty bed contact time (EBCT) of 2 h. The treatability constant at 27°C was found to be 41.963. A maximum COD removal efficiency ...

  • Waste Water Treatment Processes Explained

    SUNCOAST WASTE WATER MANAGEMENT  presents  AEROBIC -verses- ANAEROBIC THE AEROBIC PROCESS There are two basic types of sewerage treatment processes, which are the Aerobic process and the Anaerobic process. Aerobic means with air or oxygen and Anaerobic (septic) means without air or oxygen. Aerobic bacteria are a higher life form and when digesting waste are utilising dissolved oxygen or air in ...

  • Case Study: Odor Abatement Solutions

    Odor issues related to industrial processes are not uncommon.  An odor is caused by one or more volatilized organic compounds (VOCs) that humans can perceive by the sense of smell.  The challenge is that “odor is subjective, and what is sweet to some, can be a nuisance to others.   In most cases the ...

  • Anaerobic digestion of Organic Fraction of Municipal Solid Waste (OFMSW) in two-phase system

    In view of recovering energy resource from the treatment of Organic Fraction of Municipal Solid Waste (OFMSW), anaerobic digestion of OFMSW prior to aerobic composting as post-treatment was considered. This study aimed to determine the operational characteristics and efficiency of a two-phase system composed of a fed-batch hydrolysis reactor (phase I) and a methanogenic Upflow Anaerobic Sludge ...

  • Municipal waste water treatment plant case study

    A municipal WWTP in the North of England was experiencing significant problems with accumulations of FOG in the Wetwell at the head of the treatment plant. The FOG would form a solid cap over the well several feet thick. This put considerable strain on the pumping gear, interrupted the performance of the float switches and required regular manual intervention from the staff. High costs were also ...

  • Waste water treatment of USA companies with low-cost value

    Now day’s waste water grabs everyone’s attention, which must need to purify solution, by using different procedures. There are numbers of sewage solution companies are available in the USA. The industries are offers several tools to analyze the wastewater, and then purifying it. The beverage and food processing industries have unique challenges to providing advanced beverage and food ...

  • Unpleasant Odors Successfully Removed Using Biological Waste Water Treatment

    System designed by Dresden DAS Environmental Expert successfully treats landfill leachate from hazardous waste landfill in Grumbach, Germany DAS Environmental Expert has designed a system for the treatment of landfill leachate that currently treats the wastewaters of the AMAND Umwelttechnik Grumbach ...

  • Effect of temperature on composting residual Organic Fraction of Municipal Solid Waste (OFMSW) after anaerobic digestion

    Aerobic composting is generally considered as a necessary post-treatment for residual solids after anaerobic digestion. This study aimed to determine the effects of temperature on biodegradation, microbial population density in composting residual OFMSW after anaerobic digestion. Four composting runs at different set temperatures were conducted. The rate of ...

  • Sewage treatment plant

    BONO ARTES has developed an activated sludge process called BIOCLAR, which is a great technological step forwards compared to conventional methods. A large part of civil and industrial installations, especially in developing countries, is located in remote and secluded areas where there is no possibility for connection to a public sewer. On the other hand, the minimisation of the impact on the ...

  • Critical Role of Aerobic Uptake in Biological Phosphorus Removal

    ABSTRACTThe use of biological phosphorus removal (BPR) to remove phosphorus (P) from municipal wastewaters is well-established, and especially in recent years, there has been a significant increase in the number of utilities practicing BPR. The basic BPR mechanism includes two distinct steps: anaerobic P release, and aerobic P uptake. However, BPR design and optimization efforts have typically ...

  • Aerobics to the Rescue - Using Compatible Technologies to Improve Groundwater Remediation

  • Water mixing in waste lagoons

    Man-made lagoons have been used worldwide for the treatment of domestic and industrial wastewater, it seems, forever. All waste lagoons were first designed and thoughtfully planned considering their locations, soil makeup, and waste reduction processes prior to being implemented. The biological process of organic waste reduction is always a consideration of waste lagoon designs. There are three ...

  • Turning waste into power

    Economic, social and environmental factors dictate the necessity to manage waste to a new level. Wastewater plants, landfills, farms and food plants are all the owners of biomass that can be digested to produce biogas and turned into power. Biogas can be burned directly in boilers for heat recovery and used for manufacturing, heating or cooling; this is the simplest method of direct biogas ...
