reduction. In Italy about 6x105tons of paper sludge is yearly produced giving 60kg of paper ash per ton. In this project, the ash coming from burning of paper mill sludge from primary mechanical separation process, fired as single fuel, was studied in order to evaluate its use as supplementary cementitious material in concrete manufacturing.

The deinked fiber is made into a new paper product in the same way that wood fiber, see papermaking. Byproducts. The unusable material left over, mainly ink, plastics, filler and short fibers, is called sludge. The sludge is buried in a landfill, burned to create energy at the paper mill or used as a fertilizer by local farmers.

At Triark, we stock a huge range of spare parts and accessories for diaphragm pumps, air operated pumps, rotary vane pumps and peristaltic pumps, all available for next day delivery in the UK .
In this paper we experimentally describe the recycling of the waste products like STP Sludge and Fly ash by incorporating them into bricks. It is a practical solution for problems like cost expenditure on waste management and its effect on environment. The STP sludge and Fly ash is extremely close to brick clay in chemical com-
Dec 22, 2008· Consultation on paper sludge ash protocol. ... Currently, 125,000 tonnes of paper sludge ash (PSA) is generated annually by UK paper mills, with 30% of this going to landfill. This figure could rise during 2009/10, with some expansion planned at existing mills and a new newsprint mill becoming operational.
dried sludge and sludge ash as brick making materials. The maximum percentages of dried sludge and sludge ash that can be mixed with clay for brick making are 40% and 50% respectively. The compressive strength of the bricks is 87.2 N/mm2 for 0% sludge, decreasing to 37.9 N/mm2 for 40% dried sludge, and 69.4 N/mm2 for 50% sludge ash.
More recently, beneficial uses for dewatered sludge and ash from sludge incineration have been developed. The more advanced methods of sludge or ash disposal are usually targeting to reuse the composted or digested sludge in agriculture as a fertiliser or in landscaping, or reuse phosphorus and/or nitrogen in agriculture as an additional ...
Paper sludge ash (PSA) was obtained from Aylesford Newsprint Ltd., a major UK newsprint . 97 . manufacturer producing 400,000 tonnes per year of recycled newsprint from 500,000 tonnes of waste ...
"Biosolids" is a term often used in wastewater engineering publications and public relations efforts by local water authorities when they want to put the focus on reuse of sewage sludge, after the sludge has undergone suitable treatment processes.In fact, biosolids are defined as organic wastewater solids that can be reused after stabilization processes such as anaerobic digestion and composting.
Pulp and paper companies in Maine often burn wood, bark or paper-mill sludge to make electricity. One way to dispose of this wood ash is to put it in a landfill and landfill space is becoming scarce and costly. That's why other methods of ash disposal have been developed.
Solid Waste Management in Pulp and Paper Industry: Waste generation is the first and most crucial element of waste management. Quick identification, and measurement of solid waste generated at the various stages of pulp and paper manufacture is the beginning of sound waste management.
Waste paper sludge ash (WPSA): Waste paper sludge was obtained from JML waste paper corporation, Pathankot, Punjab, India. It was then sun dried and incinerated so as to convert it into ash. The ash was sieved through 90 micron (0.0035") Indian Standard sieve. The specific gravity of waste paper sludge ash was found to be 2.6.
discovering the high potential of pulp and paper production residues Unfortunately the current legislation affecting pulp and paper production residues does not allow the full exploitation of the high potential of these resources.
ECOFLUID bubbling fluidized bed boilers form an important part of ANDRITZ bio-energy solutions and are used for steam and power generation from biomass and different alternative fuels, such as sludges, RDF, and residues.

government support the demand for Fly Ash Bricks About 150 million ash bricks have been manufactured and used in house consumption. All the plant use similar processes called FAL-G Technology by using fly ash, cement/lime and gypsum to manufacture fly ash bricks. These bricks are water cured, thus avoiding the need of
The production of conventional soil stabilisers such as cement or lime involves non-renewable natural resource and energy consumption and high carbon dioxide emissions; therefore, alternative stabilisers are sought. This study used waste paper sludge ash (PSA) to treat three different clays.
The ash in paper sludge can also be recovered to replace sand as a raw material in mortar production. However, the use of paper sludge for commercialized ethanol production is currently a challenge due to its low solid content and high pH.

4.1.2. Concrete containing waste paper sludge ash (WPSA) Slump test: The slump values of all the mixtures are represented in TABLE 4. The slump decreased with the increase in waste paper sludge ash content. Waste paper sludge ash particles absorbed more water as compared to cement and thus decreasing the workability of concrete mix.
