Light Environmental has developed a range of standard stand-alone products which can be combined into process and system configurations to meet each PCB manufacturer¡¯s needs.
These goals may include the following:
- Compliance with discharge limits
- Sludge reduction
- Metals recovery
- Recycled reuse water
- Reduced capital costs
- Reduced operating costs
One of the most difficult PCB manufacturer wastes to treat is that containing resistant chlelators, developers and stripping solutions.
Light Environmental has developed the TREAT-RESIST System which removes both the resist polymer and metals using filtration. The effluent from this system can be sent directly to the final Neutralization System and discharged. The TREAT-RESIST System can be operated as a batch or on a continuous flow basis. The solids residue is easily dewatered in a standard filter process.
Advantages to our PCB Wastewater Treatment:
- Custom design with standard treatment equipment that works
- Superior product quality
- Easy installation and operation of equipment
