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:
