Dryers

The dryer in the W rtsil Bio-Sludge Treatment system can process all the sludge from wastewater and food waste before incineration. The purpose is to reduce the volume by drying. A cruise ship produces large quantities of wastewater and food waste. This waste must be treated to comply with the environmental requirements for no pollution at sea

BioCo™ | Veolia Water Technologies - North America

The BioCo™ dryer can be fitted with two optional systems: BioCo™ Energy Exchange System (BEES): Heat recovery on drying air The BioCo™ Energy Exchange System (BEES) is a condensing heat exchanger which enables condensation of part of the water vapour contained in the drying air and raising the temperature of the cooling water circuit

The sticky behavior of pulp and paper mill biosludge

The sticky behavior of pulp and paper mill biosludge during drying, TAPPI Journal 2019 Application: Understanding the sticky behavior of biosludge after being dried to a certain solids content may help pulp and paper mills to improve the thermal efficiency of biosludge dryers and to turn biosludge into an attractive fuel for burning in biomass boilers

The Valmet biosludge treatment system

The Valmet biosludge treatment system. The Valmet system offers a cost-effective solution. The sludge is treated to improve dewatering, mixed into the black liquor and evaporated in the evaporators. The process has very low impact on pulp mill processes, is safe for operators and the environment, needs little maintenance and is also easy to

Municipal Biosolids Systems - Vulcan® Drying Systems

Mixed material is conveyed through the dryer where the heat removes excess moisture and reduces pathogens. Proprietary biosolids dryer technology ensures a uniform and consistent ≥90% dry solids end product. Processed material leaves the dryer through a knock out box 4 and is carried to a screen shaker 5 where it is processed to a uniform size

BioCon™: Reducing 1,300 Miles of Biosolids Hauling Risks

The BioCon™ dryer is designed for 36 wet tons per day and will produce 5.5 tons of dried product. That equates to an 85% reduction in volume and weight. This reduction will have a positive impact on the community with less truck traffic, emissions, noise, and costs

J-Mate® Continuous Dryer - Evoqua

Description. The J-Mate Continuous Dryer, a JWI product, reduces disposal costs by removing moisture from dewatered cake. It is designed to be used for second stage volume and weight reduction downstream from a J-Press filter press or other dewatering systems

SOLAR DRYING TECHNOLOGY YIELDS CLASS A BIOSOLIDS

Sep 21, 2005 Harris calculates that it requires about 30 kW-hours/dry ton to operate the solar drying facility, versus an estimated 600+ kW-hours/dry ton to operate a conventional heat dryer. “Total operating and maintenance costs for the dryer are about $42/dry ton, based on 300 dry tons/year processed,” he says

Drying characteristics of biosludge from pulp and paper

For biosludge to burn effectively, however, it must be dewatered or dried to at least 30%–35% solids. A sys-tematic study was conducted to examine the drying characteristics of biosludge collected from pulp and paper mills at various temperatures using a thermogravimetric dryer. The drying behavior of the tested biosludges was similar

Drying biosludge with a high-velocity cyclone dryer

The purpose of this project is to investigate the possibility to dry biosludge in a high-velocity cyclone dryer since the technology has been shown to be able to handle sticky materials. The sludge used in this project originates from the biological wastewater treatment at the pulp and paper mill Mets Board Husum, located in Husum, Sweden

Biosolids - Wikipedia

Biosolids can be an ideal agricultural conditioner and fertilizer which can help promote crop growth to feed the increasing population. Biosolids may contain macronutrients nitrogen, phosphorus, potassium and sulphur with micronutrients copper, zinc, calcium

Bio-Scru Biosolids Dryer System | BCR Solid Solutions

BCR has designed the IC series biosolids dehydration system with design criteria to address the needs of the small to medium size municipality and to keep operator attention and maintenance cost to a minimum. The BCR IC Series BIO-SCRU sludge dryer system is an automated continuous processor. All operating parameters are under the control of the PLC system and the automated process

As the challenges of disposing of Class B biosolids

The BIO-SCRU dryer delivers efficient operation in a compact design. It dries sludges other systems can’t. The BIO-SCRU dryer effectively dries a range of sludge including digested and undigested primary, and waste-activated. As is typical of most regional facilities, the system also dries mixtures of such sludge with ease
