Eco Compliance Corporation


In order to satisfy NPDES discharge requirements, Eco Compliance designed and constructed a system using calcium carbonate (soda ash) to treat low-pH wastewater from a food manufacturing plant.  Elements of the system included a reagent tank, transfer pumps, pH probes and controllers, flow diverter valve and chart recorder.  We also designed and constructed the system's process control panel, provided fine-tuning of the system on start-up, and conducted operational and maintenance training and documentation.

To minimize threats to worker safety while maintaining compliance with NPDES  discharge requirements, Eco Compliance designed a novel carbon dioxide system to treat high-pH wastewater from a cement processing plant.  Use of CO2 was selected because of proven performance and safety  benefits  over  conventional  acid treatment  systems.  The design package included a discussion on process chemistry, process instrumentation, design drawings, equipment lists and capital costs.

To control the offsite migration of wastewater, Eco Compliance prepared Chemical, Civil and Structural Engineering design plans, specifications and capital cost estimates for an industrial process wastewater collection system for discharge to the local sewer.  System components included a surface water conveyance channel, culvert, sump, pumps, and level and flow controllers and alarms.  We also provided expertise during system construction and start-up.

Eco Compliance has provided chemistry expertise to resolve several issues related to algae growth in water and wastewater.  For one client, the algae disrupted pH levels in the wastewater, causing violations to NPDES discharge requirements.  Eco Compliance identified the causes of the problem, and recommended simple, cost-effective solutions to permanently control this unwanted growth.  For another client, algae growth in a test tank interfered with sensitive testing of medical ultrasound equipment.  Eco Compliance conducted various cost-effective bench tests to ultimately identify the causes of the problem and resolve the issue.
