About Waste Water Treatment

Industrial discharge regulations carry real financial exposure. EPA effluent guidelines under the Clean Water Act set numeric limits on BOD, TSS, oil and grease, and heavy metals for dozens of industry sectors — and permit exceedances can result in fines exceeding $25,000 per day per violation.

AMPAC USA engineers wastewater treatment systems for industrial and commercial applications where simple settling is insufficient. Product lines include membrane bio-reactors (MBR) for high-strength organic waste, sequencing batch reactors (SBR) for variable-flow industrial streams, dissolved air flotation (DAF) for oil and grease separation, and grey water recovery systems for facility reuse applications.

Systems are sized to actual flow rates and contaminant loads rather than generic rule-of-thumb designs. Each installation includes effluent monitoring capability so operators can document permit compliance and adjust process parameters as influent quality shifts.

Frequently Asked Questions

What is industrial wastewater treatment?

Industrial wastewater treatment removes contaminants from process water, cooling water, and production effluent before discharge or reuse. Depending on industry, wastewater may contain suspended solids, BOD (biochemical oxygen demand), heavy metals, oils and grease, pathogens, or dissolved chemicals.

AMPAC USA designs custom treatment trains combining physical, chemical, and biological processes to meet discharge permits and enable water reuse – turning a waste liability into a recovered resource.

What wastewater treatment technologies does AMPAC USA offer?

AMPAC USA engineers full-train wastewater treatment systems including:

DAF (Dissolved Air Flotation) – removes oils, fats, and suspended solids
Membrane Bioreactor (MBR) – combines activated sludge with ultrafiltration for high-quality effluent
SBR (Sequencing Batch Reactor) – biological treatment for BOD/COD reduction
Chemical Precipitation – heavy metal removal (chromium, copper, zinc, lead)
RO Polishing – post-biological treatment for high-purity reuse water
Grey Water Reclamation – site water recycling for irrigation and toilet flushing

What wastewater discharge regulations must industrial facilities meet?

In the U.S., industrial wastewater dischargers must comply with EPA effluent limitation guidelines (ELGs) under the Clean Water Act. Key regulatory frameworks include:

NPDES permits – for direct discharge to surface waters
Pretreatment standards (40 CFR Part 403) – for discharge to municipal sewer systems
Categorical standards – industry-specific limits for food, metal finishing, pharmaceuticals, and others

AMPAC USA designs treatment systems to meet or exceed permit conditions.

Can industrial wastewater be treated and reused on-site?

Yes. Water reuse reduces discharge volumes, lowers fresh water purchase costs, and demonstrates environmental compliance. AMPAC USA designs closed-loop systems where treated wastewater returns to production as cooling tower makeup, boiler feed (after RO polishing), CIP rinse water, or landscape irrigation. MBR + RO polishing achieves effluent quality suitable for most industrial reuse applications.
