Abaxial team members have had significant engineering experience
on the following representative process engineering projects.
This project started as a simple request to certify waste tanks under the
requirements of 40 CFR 261. Upon investigating the issues with plant
management, the project became a thorough examination of the waste
generation and collection within the plant.
Initial tasks included mapping all waste streams in the production process.
Working with the process engineers, each stream was evaluated for recycling
into the production process. If recycling was feasible, appropriate
facilities were designed and constructed. Containment and secondary
containment systems were designed for those streams not suitable for
recycling. Operating procedures and manuals were developed, working in
conjunction with the plant operating staff.
The facility started with 60 hazardous waste tanks and 140 hazardous waste
sumps. At the end of the project, there were only 20 hazardous waste tanks
and 40 hazardous waste sumps. This project was the spearhead of a project
which added 50% to the operating efficiencies of this plant.
This platerís waste pretreatment was alleged to have continual releases outside the
The project included first determining a pretreatment process, which would protect
all the various stakeholders. A process was designed that included standard metals
plating pretreatment to remove cyanide, zinc, and chrome with the additional safeguards
of hold-up tanks to allow treated wastewater to be tested prior to release.
The existing equipment was reconfigured to accomplish this process. Additional
controls, and filter press capacity were installed. The system was operated under
close supervision from the POTW until everyone was satisfied that the system would
operate as planned. The industry has retaken control of operations.
