Zero liquid discharge is a wastewater management approach designed to avoid liquid effluent discharge by treating and reusing water and concentrating residual solids.
Overview
What it means in practice
Zero liquid discharge should be read as a pollution, water or waste term. Its meaning depends on the pollutant, source, pathway, location, threshold and measurement method.
In practice, users should state the boundary, source, measurement basis and evidence. That keeps zero liquid discharge specific enough for review without turning it into a broader claim.
Why it matters
Zero liquid discharge matters because pollution language can trigger different duties, risk judgments and community concerns depending on concentration, exposure, route and local conditions.
Common misconception
A common error is to use Zero liquid discharge without naming the pollutant, source, threshold or exposure route. Those details are what make the term reviewable.
Review questions
What source, boundary or measurement method gives the term meaning? What evidence supports it? What limitation would change how a reader interprets the claim?

Review board
Comment on a specific line. Each reviewer stays separate until an editor accepts a merged draft.
Each person comments on the definition or overview in their own draft card, with role, evidence and suggested wording kept together.
