Coal-fired power plants use water to transport bottom ash and fly ash from boilers to disposal areas. This ash transport water contains high concentrations of suspended solids, requiring treatment for water recovery and environmental compliance.
Coarse ash collected from boiler hoppers requires high-volume water transport. Reynolds & Bauhm systems handle the large particle sizes and high solids loading typical of bottom ash sluicing.
Solids: Up to 30% by weight
Fine particulate matter captured by ESPs and baghouses creates slurry with fine particles that require specialised clarification and dewatering equipment.
Particle: < 100 microns
Closed-loop ash handling systems recover and recycle transport water, minimising freshwater consumption and wastewater discharge.
Recovery: 90%+ water reuse
Treatment ensures ash pond discharge meets environmental regulations for suspended solids, pH, and heavy metals.
Standard: ELG compliance
Our ash handling treatment systems include high-rate clarifiers for solids separation and dewatering equipment for sludge volume reduction. Systems are engineered for the high solids loading and large volumes typical of ash transport water.
High-rate inclined plate clarifiers handle large volumes of ash slurry water with efficient solids separation in a compact footprint.
Capacity: 25 m³/m²/h
Dissolved air flotation for fine ash particle removal and light solids separation with high solids capture efficiency.
Removal: >98% TSS
Continuous sludge dewatering reduces ash slurry volume by 80-90%, minimising disposal requirements and improving handling.
Cake: 20-25% dry solids
Pre-treatment grit removal protects downstream equipment from abrasive particles and heavy solids damage.
Benefit: Equipment protection
Intake screening prevents large debris from entering ash handling systems, protecting pumps and clarifiers.
Opening: 6-50 mm
Custom-designed storage tanks for ash slurry collection and equalization with abrasion-resistant linings.
Material: HDPE/Steel
Treated ash water can be recycled back to the ash handling system, creating a closed loop with minimal makeup water requirements. This reduces water consumption and wastewater discharge volumes.
Recirculating ash handling systems eliminate continuous water discharge, reducing environmental impact and water requirements.
Saving: 90% water reuse
Final filtration ensures recycled water meets quality standards for reuse in ash transport systems without causing equipment fouling.
Quality: < 10 ppm TSS
Automated pH neutralisation systems maintain optimal water chemistry for both equipment protection and environmental compliance.
Range: pH 6.5-8.5
Conversion to dry ash handling systems eliminates water use entirely, providing maximum water benefits and simplified disposal.
Benefit: Zero water use
