Read original source ↗Explore the equipment.
Catalogue equipment is engineering context, not a site-specific selection. Provide your actual flow and influent.
Which local textile wastewater samples are documented?
Six factory ETP-inlet samples from Gazipur, Savar and Narayanganj were collected in mid-July 2017 and published in 2018. Only before-treatment values are shown. The reported uncertainty term is preserved without assuming SD or SE.
Which discharge standard is shown?
The page shows the textile washing, dyeing and printing table in Bangladesh Environmental Conservation Rules 2023, Schedule 5 section 2. The TDS footnote excludes discharge to sea water. The Gazette was published on 5 March 2023; Rule 1(2) states immediate commencement.
Can these sample values determine my equipment size?
No. Published samples establish context, not your site design basis. Provide actual flow, measured influent, operating variability and the applicable discharge or reuse target.
