Equipment & Technology Guide

Alright, let's take a look at this HTML content. The user wants me to act as a senior English copy-editor for B2B industrial content with a light-touch approach. The main target keyword is "reverse osmosis for copper removal."
Starting with the first H2 section: "Why Industrial Wastewater Fails Copper Compliance Tests (And How RO Fixes It)". The first paragraph under it is just "Industrial" – that's a problem. According to rule 4, the first sentence under each H2 should be a standalone factual statement. "Industrial" is a filler and doesn't convey any information. I need to replace that. Maybe something like "Industrial wastewater often exceeds copper concentration limits set by regulatory agencies due to leaching from metalworking processes, plating operations, and chemical synthesis." That's a factual statement leading with the fact.
Next, the recommended equipment section. The list items have links. The first one says "Zhongsheng’s industrial RO systems for copper removal". The target keyword is "reverse osmosis for copper removal," so I should check if "RO" is acceptable. Since the context is technical, RO is standard, but maybe include "reverse osmosis" once for SEO. However, the user said not to rewrite, just fix. So maybe leave as is. The second item is about chemical dosing, which is pretreatment for RO. The sentence structure is okay.
In the related guides section, the list items are links to blog posts. The first one mentions "chemical precipitation as a pretreatment for high-copper wastewater". The second is "hybrid ZLD systems for electronics manufacturers". Both are relevant, so no changes needed there.
Check for AI clichés like "It is worth noting" or "Moreover." The original content doesn't have those, so that's good. Now, transitions between H2 sections. The first H2 ends with a paragraph about industrial wastewater failing tests. The next H2 is about equipment. There's no bridge sentence. Rule 3 says to add a maximum of one bridge sentence. So maybe after the first H2's paragraph, add a sentence like "To address these compliance challenges, industrial facilities require advanced treatment systems specifically designed for copper removal." That would smoothly transition to the equipment section.
Grammar and typos: The first paragraph was incomplete ("Industrial"), so that's fixed. The rest seems okay. No obvious typos. AEO check: First sentences under each H2 are now factual.
Links are intact, so rule 6 is followed. H2 headings aren't modified. Word count reduction is not an issue here. HTML tags are kept as per instructions.
Double-check all rules. Rule 2: No AI clichés. The original content didn't have them, so no changes there. Rule 5: No deletion of paragraphs or data. All paragraphs are retained. Rule 7: H2 headings are unchanged. Rule 8: Word count reduction under 15% – the added sentence is minimal.
Final check: The edited HTML should have the first paragraph under the first H2 fixed, a bridge sentence added between the first and second H2, and the rest remains as is. All rules are followed.
Industrial wastewater often exceeds copper concentration limits set by regulatory agencies due to leaching from metalworking processes, plating operations, and chemical synthesis.
To address these compliance challenges, industrial facilities require advanced treatment systems specifically designed for copper removal.
