The operator of the Hamilton Township Wastewater Treatment Plant in Ludlow, Pennsylvania, applied knowledge gained from an energy efficiency training conducted by the U.S. EPA Region 3 and the Pennsylvania Department of Environmental Protection. The plant’s mgd activated sludge process includes ammonia removal.

A change in the energy tariff from constant charge to time of use resulted in high energy costs at a UK Water Company’s large activated sludge plants. TruSense Process Engineering was awarded the contract to undertake the investigation of optimum operational and control methods to save energy under the new tariff while ensuring final effluent. The driven force behind the Biological Double-efficiency Process (BDP) is our unique technology and patents. Microbiological Technology Using low dissolved oxygen and high concentration activated sludge conditions, we can maximize the quantity of domesticated microorganisms in biological treatment tank.
A twist on the MBBR technology is the integrated fixed film activated sludge (IFAS) treatment process, where the media is suspended in the aeration basin and BOD removal and biological nitrification occur in the same basin. Advantages. The use of the trickling filters/activated sludge treatment process combines the best qualities of both processes. Reducing Wastewater Treatment Energy Consumption in the Activated Sludge Process Using Thermal Dispersion Flow Meters As pressure increases to monitor and manage wastewater treatment energy consumption, facility operators are looking at the activated sludge process for energy reduction opportunities.

| Sludge is the chief by-product of wastewater treatment plants, and further clearance of sludge is a major and complex environmental issue. The aeration process in secondary treatment is the highest energy consumption part of the wastewater treatment technology [3,5].
In most medium and large WWTPs with Conventional Activated Sludge systems, aeration takes up approximately 50–60% of all electricity consumption, while sludge treatment consumes 15–25% of energy, followed by secondary sedimentation Author: Rafik Oulebsir, Abdelouahab Lefkir, Abdelhamid Safri, Abdelmalek Bermad.

Larson3, Michael K. Stenstrom1* ABSTRACT: Aeration is the most energy intensive unit operation in municipal wastewater treatment, and fine-pore diffusers have been widely used to minimize power consumption.
The major drawback to using an "activated sludge" system in wastewater treatment is the expensive cost associated with the energy consumption required to meet the oxygen demand required to achieve the oxidation of organic matter, which represents about 50% of the energy consumption of the plant.
We present our analysis and conclusions of the. Abstract: The proposed methodology for optimizing energy efficiency, based on good management of the aeration process through the implementation of an appropriate control strategy, achieved reductions of more than 40% in energy consumption at the San Pedro del Pinatar Wastewater Treatment Plant (WWTP) (Murcia, Spain).
A well-developed advanced process controller has a backbone that consists of both product and process expertise. Without understanding both the functionality of the products and the needs of the process, the controller will not be able to deliver meaningful and measurable improvements to both energy efficiency and process stability.
Meaning Activated Sludge Process. The activated sludge process is one of the biological method of industrial waste waste treatment. The activated sludge process consists of converting the suspended and particulate organic matter in the raw waste water into harmless end products and new cells growth with the help of Anaerobic and Aerobic Microorganisms.

Factors pertaining to power requirement and oxygen transfer of aeration systems in biological treatment are discussed, with emphasis on the difference and effects on energy efficiency between fine bubble aeration.

Stabilization of sludge is done to diminish the pathogen content, eradicate unpleasant odors, and diminish the potential for decomposition. The cost to treat surplus amounts of waste activated sludge is very high, accounting for up to 60% of the entire operational costs of a treatment plant.
Sludge degradation is carried out by many treatment. Optimization of the activated sludge process, and return activated sludge flow rate, requires careful management of three critical parameters. Over the years, wastewater professionals have based their control decisions on measurements from batch tests supplied to various samples or from infrequent laboratory analysis.
Those are measurements done on composite samples for compliance. The carbon enriched biosolid residues are appropriate for fabrication of functionalized materials to achieve efficient wastewater remediation.
With such a process, a more sustainable municipal wastewater treatment process than that of current energy- and chemical-intensive activated sludge-based WWTPs can be expected.
It offers detailed and data-based process control solutions to stabilize plant performance, maintain consistent effluent quality, and reduce energy costs. Powerful, easily implemented statistical techniques are given to unlock the meaning of plant performance data and make informed process control decisions.
The Activated Sludge Process • In, British researchers Edward Ardern and W.T. Lockett, added the concept of recycling sludge and patented the process. • The paper they published infirst used the term “Activated Sludge”. Davyhulme Sewage Works, Manchester, UK, first full-scale activated sludge.
activated sludge floc respire using nitrate in place of free oxygen when it is lacking and release nitrogen gas as a by-product. This gas is only slightly soluble in water and small nitrogen gas bubbles form in the activated sludge and cause sludge blanket flotation in the final clarifier.

The proper performance of an activated sludge plant is enhanced with knowledge of five biological and physical elements that determine the efficiency of the process. The present work provides an overview of technological measures to increase the self-sufficiency of wastewater treatment plants (WWTPs), in particular for the largely diffused activated sludge-based WWTP.
The operation of WWTPs entails a huge amount of electricity. Thermal energy is also required for pre-heating the sludge and sometimes exsiccation of the digested sludge.
Plants can use aeration at all points of the wastewater treatment process, from equalization and the grit chamber to post-aeration. It’s most common, though, to use aeration during secondary treatment, especially in the activated sludge process.
During the activated sludge process, air pumps into the wastewater tank.To control activated sludge, you need to "have a handle" either on aeration, sludge-wasting or return-sludge flow. Aeration-rate adjustment is probably the simplest way to go.
It involves, however, more than measuring once each day aeration-basin dissolved oxygen (DO) concentration.This Activated Sludge Training Manual was prepared by the Michigan Department of Environmental Quality, Operator Training staff.
It is intended to be used as an aid in the presentation of the MDEQ Activated Sludge Process Control Training Course, along with numerous handouts, class discussion, and an abundance of slides.
