Inside the Checklist

7 Decisions That Separate
a Reliable System from a Liability

Every section maps to a real failure mode in industrial pH treatment.

DECISION 01

Daily Effluent Volume & Flow Rate

Undersized holding tanks create overflow and compliance bypass risk. Includes a sizing reference table from compact batch systems through continuous-flow configurations.

Tank Sizing Table

DECISION 02

Inlet pH & Target Discharge Range

Your POTW permit sets the floor. Explains why you should design 1.0–1.5 pH units above the minimum — and how the logarithmic scale changes the math from what you'd expect.

pH Scale Reference

DECISION 03

Tank Selection & Secondary Containment

Single-wall tanks in aggressive chemistry are a floor spill waiting to happen. Covers polyethylene compatibility, 110% containment design, and caustic storage requirements.

Containment Guide

DECISION 04

Dosing Pump & Mixer Pairing

pH overshoot is the most common automated system failure. Explains turndown ratio, why continuous mixing prevents false readings, and why both are a required pairing.

Overshoot Explained

DECISION 05

Level Measurement in Corrosive Tanks

Contact sensors degrade fast in acidic or alkaline environments. Covers non-contact radar vs. floats and transducers, and what a reliable transfer trigger looks like.

Radar vs. Contact

DECISION 06

Controller, Automation & IIoT Reporting

What automated compliance discharge logging looks like in real operation. Covers remote monitoring, alarm integration, backup power, and what to look for in a process controller.

IIoT Reporting

DECISION 07

Flow Measurement for Compliance Documentation

Your POTW can dispute unverified volumes. Why magnetic flow meters outperform paddlewheel meters in industrial wastewater — and why totalizer data must sync with your compliance report.

Magmeter vs. Paddlewheel

Print-Ready One-Page Audit Sheet

All 7 decisions condensed into a single printable checklist — Yes / In Progress / Not Addressed. Bring it to your next vendor meeting, internal review, or site walk.
