PRE-TREATMENT SYSTEMS
Pre-treating wastewater before using CAST technology can result in purer recovered resources, but since your wastewater needs are unique, it's important to use the right system. CASTion can help with pre-treatment systems such as multi-media filtration for suspended solids removal or ultrafiltration to remove organic materials. CASTion will design and assemble the proper pre-treatment components for your wastewater, using the following technologies:
Microfiltration
For the removal of precipitated suspended solids, we use microfiltration. At CASTion, we have extensive experience with both conventional and advanced physical chemical separation technologies. Our microfilters are well suited for:
- Removal of precipitated heavy metals as pre-treatment to a primary resource recovery system
- Removal of silica and hardness from cooling tower blowdown and concentrated brine solutions for wastewater recovery
- Pre-treatment for nanofiltration and reverse osmosis systems
- Environmental compliance
- High-molecular-weight separation tasks
Ultrafiltration
For organics, CASTion uses ultrafiltration membrane separation. Our long-standing relationship with all of the major membrane manufacturers enables us to provide the right tools to deliver the best results for you. Here is a partial list of ultrafiltration applications:
- Organics separations
- Colloidal particle removal
- Protein separation
- Oil and grease removal
- Pre-treatment to a primary resource recovery process
- Color removal
- Bacteria and pyrogen removal from recovered wastewaters
Make sure you get a pre-treatment system that delivers the best recovery results. Contact CASTion to obtain a system tailored to your unique needs.
