Effect of ozonation on activated sludge from pulp and paper industry
Aerobic biological treatment with activated sludge is the predominant process all over the world for treatment of pulp and paper industry wastewater. 50–70% of the biodegradable organic material is oxidized to CO2 and the rest is converted to bacterial biomass, typically termed as excess sludge or waste activated sludge (WAS). Handling and disposal of WAS in general and in particular from the ...

Chemical speciation of trace metals in the industrial sludge of Dhaka City, Bangladesh
The objective of this study was to assess total concentration and chemical fractionation of trace metals in the industrial wastewater and sludge collected from seven different types of industries in Dhaka City, Bangladesh. The sludge from industries is either dumped on landfills or reused as secondary resources in order to preserve natural resources. Metals were analyzed using inductively ...

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 ...

Acid dye removal from industrial wastewater by adsorption on treated sewage sludge
This study investigated the suitability of sewage sludge for the removal of Acid Blue 93 industrial wastewater. Washed sewage sludge (WS) and sludge activated carbon (AS) were used as adsorbents. The effect of pH, contact time, adsorbent dose and adsorption temperature was studied. Equilibrium isotherms for the adsorption were analysed by Freundlich and Langmuir isotherm models. The ...

Effect of SBR feeding strategy and feed composition on the stability of aerobic granular sludge in the treatment of a simulated textile wastewater
Treatment of the highly polluting and variable textile industry wastewater using aerobic granular sludge (AGS) sequencing batch reactors (SBRs) has been recently suggested. Aiming to develop this technology application, two feeding strategies were compared regarding the capacity of anaerobic–aerobic SBRs to deal with disturbances in the composition of the simulated textile wastewater feed. ...

Agrior Project, Chaudière-Appalaches, Quebec, Canada
Compost Drying Application Agrior makes high value organic fertilizers by composting a mixture of animal manure and organic municipal and industrial wastewater treatment sludge. A DRY-REX low-temperature drying system was designed and installed at Agrior’s facility to dry the mixture into high-quality compost. The low-temperature process results in the drying of the manure with minimal ...

Upgrading of sewage treatment plant by sustainable and cost-effective separate treatment of industrial wastewater
The Olburgen sewage treatment plant has been upgraded to improve the effluent quality by implementing a separate and dedicated treatment for industrial (potato) wastewater and reject water. The separate industrial treatment has been realized within a beneficial public-private partnership. The separate treatment of the concentrated flows of industrial wastewater and sludge treatment effluent ...

The connection and difference between low temperature sludge drying and sludge drying
The sludge drying technology has an early origin. In the early 19th century, the Germans invented the world's first plate and frame filter press. Today, after two hundred years of development, various types of filter presses have been born for different scenarios. The domestic sludge drying industry started late, sprouting in the period of reform and opening up in the late 1970s. Due to the ...

Speciation of heavy metals in electroplating industry sludge and wastewater residue using inductively coupled plasma
Abstract: The speciation of metals in environmental samples is a critical factor in assessing the potential environmental impacts, before their disposal. The distribution and speciation of toxic heavy metals in plating wastewater residues and sludge was investigated for four samples using sequential extraction method. Tessier method was used to fractionate the metal content into exchangeable, ...

The investigation of paper mill industry wastewater treatment and activated sludge properties in a submerged membrane bioreactor
The paper mill industry produces high amounts of wastewater and, for this reason, stringent discharge limits are applied for sustainable reclamation and reuse of paper mill industry wastewater in many countries. Submerged membrane bioreactor (sMBR) systems can create new opportunities to eliminate dissolved substances present in paper mill wastewater including. In this study, a sMBR was ...

What is Sludge Dewatering & What is it Used For?
In fact, filter presses produce excellent cake dryness and, in many cases superior cake dryness as compared to other filtration equipment. What is “Sludge”? Simply stated, “sludge” is a semi-solid slurry that can be produced from a variety of industrial and municipal processes. The purpose of sludge dewatering is to reliably and efficiently concentrate the wastes into high ...

Thermal drying technology for advanced sludge treatment
With the rapid increase of urban sewage treatment rate, the amount of sludge generated will inevitably increase accordingly, and the problem of consumption is becoming more and more prominent, which needs to be solved urgently. The moisture content of sludge is the key to solve the problems encountered in sludge treatment. To achieve deep dewatering of sludge, the more economical method is to ...

Clean production in stone cutting industries
The stone cutting industry uses high volume of water for cooling purposes and produces large volume of sludge. The disposal of both the wastewater and the sludge to a solid waste disposal site is costly and environmentally unacceptable. Wastewater and sludge from stone cutting industries in Jordan has been characterised and reused in various processes. Stone cutting industries can be modified to ...

Sludge treatment in Germany more than 50 years of experience current discussions – future prospects
Abstract In Germany, nowadays, more than 97% of inhabitants and industry are connected to modern wastewater and sludge treatment systems. Long-term experience exists in Ger-many especially with sludge digestion. These experiences will be presented and a spe-cial focus will be on technologies for sludge pre-treatment such as e.g. thermal hydrolysis or technical solutions to recycle the nutrients ...

Aqwise`s poster at the 2008 Weftec convention - Distribution of microbial population within a moving bed bio-film reactor (MBBR) combining a `denitrfiltration` unit
Introduction At high influent N levels , there is a need in Pre- and Post (Endogenous)-denitrification stages, requiring addition of an external electron donor. Systems based on the MBBR (Moving Bed Bio-film Reactor) process have high potential for treating domestic and industrial wastewater. Among process advantages: Elimination of sludge recirculation, Efficient ammonia and organic ...

Polyhydroxyalkanoate (PHA) production potential of activated sludge from food industrial wastewater treatment process
Polyhydroxyalkanoate (PHA) production by activated sludge treating food industrial wastewaters was evaluated. Influence of wastewater characteristics on PHA production activities of non–acclimatised and acclimatised sludge were determined.
