Aluminum Sulfate — Liquid, Ground, or Lump

The purpose of this standard is to provide the minimum requirements for aluminum sulfate, including physical, chemical, sampling, testing, packaging, and shipping requirements.

AWWA B404-2022

Liquid Sodium Silicate

The purpose of this standard is to provide the minimum requirements for liquid sodium silicate, including physical, chemical, sampling, testing, packaging, and shipping requirements.

AWWA B405-2024

Sodium Aluminate

The purpose of this standard is to provide minimum requirements for sodium aluminate, including physical, chemical, sampling, packaging, shipping, and testing requirements.

AWWA B406-2020

Ferric Sulfate

This standard describes dry-form ferric sulfate and liquid ferric sulfate for use in the treatment of potable water, wastewater, or reclaimed water.

AWWA B407-2024

Liquid Ferric Chloride

This standard describes ferric chloride in aqueous (liquid) form for use in the treatment of potable water, wastewater, and reclaimed water.

AWWA B408-18

Liquid Polyaluminum Chloride

This standard describes polyaluminum chloride (PACl) in aqueous (liquid) form for use in the treatment of potable water, wastewater, and reclaimed water.  This standard can be referenced in specifications for purchasing and receiving liquid PACl and can be used as a guide for testing the physical and chemical properties of liquid PACl samples. The stipulations of this standard apply when this document has been referenced and then only to liquid PACl used in the treatment of potable water, wastewater, and reclaimed water.

AWWA B451-2023

Standard for Poly (Diallyldimethylammonium Chloride)

The purpose of this standard is to provide the minimum requirements for polyDADMAC products, including physical, chemical, packaging, shipping, and testing requirements, and to provide the means of developing requirements for specific polyDADMAC products.

AWWA B452-2020

EPI-DMA Polyamines

This standard describes epichlorohydrin dimethylamine (EPI-DMA) polyamines for use in the treatment of potable water, wastewater, and reclaimed water.

AWWA B453-2024

Polyacrylamide

The purpose of this standard is to provide the minimum requirements for polyacrylamide (PAM) products, including physical, chemical, packaging, shipping, and testing requirements and to provide the means of developing requirements for PAM products.
