The PWTAG Standards | Pool Water Treatment Advisory Group
In a European initiative from the UK Drinking Water Inspectorate, PWTAG has been involved in discussions about Europe-wide CEN standards for pool water chemicals. (The DWI, until 1999, organised an approval system for pool chemicals.) There are British and European Standards for these fourteen chemicals: Sodium chloride used in electrochlorination

PWTAG Technical Notes | Pool Water Treatment Advisory Group
Technical Notes 26 March 2025. PWTAG Technical notes are updates or new material for the standards and guidance given in the PWTAG book, Swimming Pool Water and the PWTAG Code of Practice and should be read in association with these publications. PWTAG keeps pool operators up to date by providing guidance through these technical notes on the issues of the day.

PWTAG Code of Practice | Pool Water Treatment Advisory Group
The code is based on the 2009 PWTAG book, Swimming Pool Water: treatment and quality standards for pools and spas. It does not replace the book. It does not replace the book. Operators should still refer to it, and it provides some of the basics for PWTAG’s training material.
The Pool Water Treatment Advisory Group recommends dosing pool water with PAC continuously by peristaltic pump at 0.1 mL/m 3 of the circulation flow in the UK and other European countries (Pool Water Treatment Advisory Group 2015). Very little is known about filter monitoring practices in most swimming pools but monitoring filter performance

The typical operational setting is for a PAC product is around 0.1ml/m3/hr. This may need adjusting to suit the prevailing conditions of the pool water. For example; a heavily polluted pool, such as a

- Are natural flocculants a sustainable technology for water and wastewater treatment?
- Finally, the future prospects, challenges and recommendations are also provided in order to advance the developments of natural flocculants to enable them to be a long-term sustainable technology for water and wastewater treatment. 2. Dyes wastewaters Dyes have been used in practically all spheres of daily life since the beginning of mankind.
- Why is flocculation important in industrial wastewater treatment?
- Flocculation is an essential phenomenon in industrial wastewater treatment. Inorganic coagulants (salts of multivalent metals) are being commonly used due to its low cost and ease of use. However, their application is constrained with low flocculating efficiency and the presence of residue metal concentration in the treated water.
- Can natural coagulants/flocculants be used in industrial wastewater treatment?
- Despite the outstanding natural properties, biodegradability, and efficacy of natural coagulants/flocculants (NC/Fs) in industrial wastewater treatment, their significant potential to remediate such effluents is underappreciated, particularly in commercial scale applications.
- Can natural flocculants remove dyes and heavy metals in wastewater treatment?
- The natural flocculants have wide and indispensable application for removing contaminations such as dyes and heavy metals in the wastewater treatment. The performance of natural flocculants for treating dyes and heavy metals in wastewater is closely related to many system characteristics such as pH and temperatures.
