Paint
Problem: A paint manufacturer, that produces both oil and water based paints, needed help to solve their liquid sludge problem. At that time the wastewater was batch treated and consisted of a chemical addition process followed by settling. This was to be changed in the near future to a continuous type treatment system. The settled sludge consistency varied form 5% to 10%. The plant wanted to ...

Increased plant efficiency, City of Checotah, Oklahoma
The City of Checotah, Oklahoma was experiencing excessive solids, foam and grease in their 0.5 MGD extended aeration activated sludge treatment facility. With a daily average flow of 0.25 million gallons per day, the plant had tremendous amounts of foam and grease in the aeration basin with the sidewalls caked with sludge. The centerwells of the clarifier were filled with foam and grease. The ...

A combined reed bed/freezing bed technology for septage treatment and reuse in cold climate regions
A combined reed bed-freezing bed (RB-FB) technology was effective at treating septage under Canadian climatic conditions over a 5-year period with average loading rates of 82–104 kg TS/m2/y. Varying hydraulic and solid loading rates as well as the increasing sludge cake with time had little to no effect on treatment efficiency, with almost complete removal of organic matter, solids, heavy ...

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 ...

What is Sludge Dewatering?
What Is Sludge vs. Sludge Cake? Sludge dewatering is a process in which a sludge slurry (sludge) is made more solid by removing water from its contents to form a sludge cake. A wide variety of municipal and industrial processes will create sludge cake after it is dewatered using various presses to form higher solids content versus a watery sludge slurry. While dewatering does not in itself treat ...

Case Study | Techase 80% Sludge Feeding Application at Lingbi WWTP
This time, let me take you to Lingbi, Anhui, China to know more about Techase “80% sludge feeding directly” process. Conventional deep sludge dewatering projects generally need to control sludge MC at about 95%, and then start the final squeezing stage for deep dewatering. In this way, some sludge with 80% MC has to be diluted first which is more complex and expensive. Techase has ...

Effect of daylight on regrowth of bacteria in anaerobically digested sludge
This study investigated the regrowth of total coliform, Salmonella, and Clostridium perfringens in anaerobically digested sludge after centrifuge dewatering in the presence and absence of daylight. Sludge cake and centrate samples were collected from a treatment plant, and half of the samples was stored in daylight and the other half was stored in dark for three weeks. The bacteria levels in the ...

Techase Environment | How to Choose a Super-convenient Filter Press?
TECHASE NEW TECHNOLOGY: 80% MC Sludge Feeding Directly As we all know, it is general necessary for conventional deep sludge dewatering flow to control the sludge moisture content at about 95%, and then the final pressing stage can be realized. However, Some sludge with 80% MC has to be diluted first which is more complex and expensive. NEW TECHNOLOGY: In response to the above problem, Techase ...

Salmon Processor 2
This facility generates 5,000 gallons of 4-6% solids sludge from their DAF using Floccin 1105. In addition, there are 24 bins per day (about 1 cubic yard each or 250 gallons) of nonedibles defined as off spec materials, cooking oil, batter, hot dogs, and chicken parts. Currently, 13 loads are transported for disposal to offsite disposal facilities that have hauling as well as tipping fees. In an ...

Synthesis and characterisation of new cationic polyelectrolytes by inverse emulsion polymerisation and their application in activated sludge dewatering
Water soluble hydrophobically associated polyelectrolytes were copolymerised with dimethyl- [2-(2-methyl-acryloyloxy)-ethyl]-alkyl ammonium bromide (alkyl: propyl, hexyl, dodecyl) (DEACn) and acrylamide (AM) in inverse emulsion. Cationic hydrophobically modified polyacrylamides having different molecule weight and cationic degree were obtained by varying the total monomer concentration and ...

A novel alum-sludge based Constructed Wetland system to reduce pollution effects of agricultural run-off: first results
This paper is a research brief highlighting the development of a novel alum-sludge based Constructed Wetland (CW) system aimed at reducing the pollution effects of agricultural run-offs. Alum sludge is a by-product of drinking water treatment plants where aluminium sulphate is used as coagulant. The alum sludge cakes were used as the main support matrix in the constructed wetland system, having ...

One of Europe’s largest wastewater plants handles 2 million challenges a day. What are yours? - Case Study
In Ambarli, Turkey, more than two million people depend on the capabilities of just one wastewater treatment plant. But as strict new environmental regulations came into effect, the city’s outdated facilities became unsustainable. To meet new demands, the new facility would need to treat 400,000 cubic meters of sewage per day within a very compact building. Technologies, costs, and ...

Škvorec WWTP Czech Republic - Case Study
Client's voice Since we had installed VOLUTE Dewatering Press in our waste water treatment plant I realized how much time we were wasting using dewatering bags. VOLUTE doesn´t need my presence and works fully automatically. I don´t sometimes even know that there is a dewatering unit in operation. Dewatering Data Sludge Type: Waste Activated Sludge Sludge Total Solids Content: ...

Case Study | Techase Completed Gexianhu River Silt Dredging Project
The river and lake scenery is always unique among the numerous sceneries. However, with the rapid development of urban economy, river and lake resources have been repeatedly damaged in economic development, and river pollution has become more and more serious. People have paid much attention to the loss of water resources caused by economic development. During the critical period of river ...

Impact of sludge retention time on sludge characteristics and microbial community in MBR
In this study, the impact of sludge retention time (SRT) on sludge characteristics and microbial community and the effect on membrane fouling in membrane bioreactor (MBR) was investigated. The results show that MBR with longer SRT has less fouling propensity, in agreement with other studies, despite the fact that the MBR with longer SRT contained higher MLSS and smaller particle size. However, ...

Environmental sludge treatment
During the process of wastewater treatment, sludge generation is an important and at times crucial issue to be addressed as inadequate sludge handling system can pose serious environmental implications. Liquid sludge can be easily thickened and reduced to a solid cake via sludge thickening / dewatering. This reduces the volume of liquid sludge significantly, usually resulting in a quite ...

Cambi – the digester `turbo charger`
ABSTRACT A new patented process design has re-invented thermal hydrolysis in sludge treatment. The first plant from Cambi for hydrolysis of sewage sludge was built in 1995 at the HIAS WwTP, Hamar, Norway for a design capacity of 3500 Mg DS/year. The sludge is directly heated by injection of live steam. During internal recycling of steam a low energy consumption is secured. Predewatering raw ...
