Full title and description

ISO 10086-2:2004 — Coal — Methods for evaluating flocculants for use in coal preparation — Part 2: Flocculants as filter aids in rotary vacuum filtration systems. This part specifies a laboratory method for the comparative evaluation of the performance of flocculants when used as filter aids in rotary vacuum filtration of a given coal slurry, helping users compare effectiveness across products and operating conditions.

Abstract

Defines a standardized comparative test procedure for assessing flocculant performance as filter aids on rotary vacuum filters, including relevant test conditions, measured performance indicators (for example filtration rate and cake moisture) and repeatability considerations to allow objective comparison between flocculants on the same slurry.

General information

• Status: Published (International Standard).
• Publication date: January 2004 (Edition 1, 2004-01).
• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 73.040 — Coals.
• Edition / version: Edition 1 (2004).
• Number of pages: ISO lists 12 pages (national/adopted versions sometimes show additional front matter — e.g., some national (BS) publications list about 18–20 pages).

Scope

Specifies a laboratory method for the comparative evaluation of flocculants used as filter aids specifically in rotary vacuum filtration systems applied to coal slurries. The procedure is intended to allow performance comparison on a given slurry under controlled, repeatable conditions and does not prescribe plant-scale optimization or treat all possible filter types.

Key topics and requirements

• Standardized test arrangement and operating conditions for rotary vacuum filtration comparative trials.
• Preparation and characterization of the test slurry and control of variables to ensure repeatability.
• Performance metrics such as filtration rate, cake moisture/solids content, solids retention and clarity of filtrate.
• Guidance on comparative evaluation and reporting of results to support selection of flocculants for a specific slurry and filter arrangement.

Typical use and users

Used by coal preparation and mineral processing engineers, laboratory testing facilities, flocculant manufacturers and suppliers, R&D teams evaluating polymer performance, and quality/control personnel responsible for filter aid selection and specification. The standard supports laboratory-scale comparison prior to plant trials.

FAQ

Q: What is this standard?

A: An ISO international standard (ISO 10086-2:2004) that defines a comparative laboratory method for evaluating flocculants when used as filter aids in rotary vacuum filtration systems for coal slurries.

Q: What does it cover?

A: The test arrangement, key operating conditions, slurry preparation and the performance indicators to be measured (for example filtration rate and cake moisture) to allow objective comparison of flocculants on the same slurry; it is focused on rotary vacuum filtration and laboratory comparative assessment rather than full-scale plant optimization.

Q: Who typically uses it?

A: Process and test laboratory engineers in coal preparation and mineral processing, flocculant suppliers and R&D groups that need to benchmark polymer/filter-aid performance before pilot or plant trials.

Q: Is it current or superseded?

A: ISO 10086-2 was published in January 2004 and is listed as an active/published International Standard by ISO. ISO standards are subject to periodic review; national adopted versions may include additional front matter. Users should check the ISO catalogue or their national body for the most recent review status before relying on it for regulatory or procurement decisions.

Q: Is it part of a series?

A: Yes — ISO 10086 is a multi-part series on methods for evaluating flocculants in coal preparation (for example, ISO 10086-1 covers basic parameters). Users should consult other parts of ISO 10086 when a broader test program is needed.

Q: What are the key keywords?

A: Flocculant evaluation, filter aid, rotary vacuum filtration, coal slurry testing, filtration rate, cake moisture, coal preparation, ISO 10086-2:2004.
