Sludge Treatment and Disposal Technologies
Most wastewater treatment processes produce a by-product that purifies wastewater before it is released into local waterways. This by-product is named as sludge. Typically in solid, semi-solid or liquid state, it is in fact an amalgamation of all the liquid wastes that are discharged by domestic houses, commercial properties, industry, and/or agriculture after aerobic biological treatment. ...

Improvement of an integrated system of membrane bioreactor and worm reactor by phosphorus removal using additional post-chemical treatment
A membrane bioreactor (MBR) coupled with a worm reactor (SSBWR) was designed as SSBWR-MBR for sewage treatment and excess sludge reduction. However, total phosphorus (TP) release caused by worm predation in the SSBWR could increase the effluent TP concentration in the SSBWR-MBR. To decrease the amount of TP excreted, chemical treatment reactor was connected after the SSBWR-MBR to remove the ...

A combined process of non-thermal plasma with sludge stabilization for the simultaneous reduction of odor and organic waste
Odor emissions and sludge disposals have become most challenging issues in many sludge treatment plants, and separate chemical oxidation processes have been commonly employed for these problems. It is, therefore, necessary to develop a combined process that simultaneously reduces the odor emissions and the amount of waste sludge. In this study, a non-thermal plasma reactor using a dielectric ...

Reductions in greenhouse gas (GHG) generation and energy consumption in wastewater treatment plants
Greenhouse gas (GHG) emission and energy consumption by on-site and off-site sources were estimated in two different wastewater treatment plants that used physical–chemical or biological processes for the removal of contaminants, and an anaerobic digester for sludge treatment. Physical–chemical treatment processes were used in the treatment plant of a locomotive repair factory ...

A modified anaerobic digestion process with chemical sludge pre-treatment and its modelling
Activated Sludge Models (ASMs) assume an unbiodegradable organic particulate fraction in the activated sludge, which is derived from the decay of active microorganisms in the sludge and/or introduced from wastewater. In this study, a seasonal change of such activated sludge constituents in a municipal wastewater treatment plant was monitored for 1.5 years. The chemical oxygen demand ratio of ...

The sludge dryer can treat all kinds of sludge
Sludge is a collective term for various types of sediments and floating objects produced by different treatment processes in water supply and wastewater treatment. The composition and properties of the sludge mainly depend on the composition, properties and treatment process. According to different classification standards. There are many classification methods for sludge, which are briefly ...

The function of sludge drying
Drying the sludge has the following advantages: (1) Reduction: Due to the high water content of the sludge, the volume is large and fluid. After the above process, the volume of sludge is reduced to one tenth of the original, and it is converted from liquid to solid, which is convenient for transportation and consumption. (2) Stabilization: The sludge has a high content of organic matter, which ...

Sludge reduction treatment in urban sewage treatment plant
Sludge is the sediment produced by wastewater treatment, including solid particles, such as sludge, sand, fiber, animal and plant residues and their solidified flakes, various colloids, adsorbed organic matter and metal elements, microorganisms, bacteria, insect eggs, weed seeds and other solids embedded in wastewater. The sewage sludge of the municipal sewage treatment plant is mainly composed ...

7 Common Pitfalls when you choose a Chemical Coagulation Water Treatment System to Treat Your Water
Pretreatment processes in water treatment systems are often crucial to maintaining efficiency and longevity of the downstream equipment, such as membrane filtration. Many systems incorporate a coagulation step that will encourage small suspended solids to aggregate and fall out of solution. By eliminating the larger particles in the solution, filtration membranes won’t foul, tear or clog ...

Electrocoagulation Solutions - Technology meets needs of food & beverage wastewater treatment - Case Study
The effects of water scarcity and stricter environmental regulations placed on water usage are increasing the cost of using freshwater globally. The consequences of these increasing costs on food and beverage companies are twofold, since the companies are charged for both the water that they utilize in their processes and on their wastewater discharge. Additionally, the food and beverage ...
