For more than 20 years, we have provided finishers with waste treatment systems that are compliant and cost-effective. Walgren waste treatment systems are engineered for batch treatment or continuous flow through operation, with smallest-possible footprint and lowest energy demand. Walgren is the only major waste treatment manufacturer in the finishing industry with a dedicated, in-house controls group. This allows controls architecture for large-capacity systems to be computer-modeled and evaluated in detail. Controls can function independently, or interface with a plant-wide system. Walgren provides control panels and full process instrumentation; SCADA systems can be implemented for highest-volume systems. Our waste treatment systems typically incorporate these modules and technologies: - Tanks, in stainless steel, mild steel, FRP, PVC, polypropylene
- Pumps and delivery systems
- Chemical storage
- Sludge concentrators
- Clarifiers/ flocculation
- Ion exchange
- Regeneration for chromic acid, nitric acid, sulphuric acid
- Membrane separation
- Filter presses
- Polishing filters
- Mixers / agitation
- PH probes and control
- Controls, with PC or PLC
- 24-hour modem support
- Spill prevention
- Recycling and resource recovery
- Waste minimization
- Dischargeable hazardous substance management
- Documentation customized to your requirements
In addition to wastewater treatment, Walgren supplies fume scrubbers, air scrubbers and all-mechanical chrome scrubbers. Walgren provides expert technical support to assure the long-term performance and efficiency of every finishing waste treatment system it sells. The Walgren Advantage: We Build – and Deliver – on Time! | |
