This module provides a summary of the proposed disinfection treatment technique and must be accompanied by appropriate plans and specifications.

Module 9A: Iron and Manganese (3900-PM-BSDW0254J)
Module 9A is intended for systems proposing iron and manganese removal in the form of aeration, chemical oxidation, lime-soda softening, manganese greensand filtration, ion exchange, polyphosphate sequestration, or sodium silicate sequestration. This module provides a summary of the proposed iron and manganese removal treatment technique and must be accompanied by appropriate plans and specifications.

Module 9B: Nitrate Removal (3900-PM-BSDW0254J)
Module 9B is intended for systems that need nitrate removal to keep concentrations below the primary maximum contaminant level. This module provides a summary of the proposed treatment technique and must be accompanied by appropriate plans and specifications.

Module 9C: PFAS Removal (3900-PM-BSDW0254J)
Module 9C is intended for systems proposing treatment to remove PFAS using GAC or ion exchange in treatment trains of at least 2 (two) pressure vessels in series. This module provides a summary of raw water quality and feed water quality if the system has existing pre-treatment prior to the proposed PFAS treatment vessels. Additionally, this module provides a summary of the proposed design for the selected PFAS treatment technique and must be accompanied with appropriate plans and specifications. Operating procedures for different vessel operating scenarios may be requested for additional evaluation.

Module 10: Corrosion Control (3900-PM-BSDW0254K)
Module 10 is intended for systems using corrosion control measures. This module provides a summary of corrosion control techniques and equipment and must be accompanied by appropriate plans and specifications.

Module 11: Organics Removal (3900-PM-BSDW0254L)
Module 11 is intended for systems that need organics removal to comply with a primary maximum contaminant level. This module provides a summary of methods and equipment for organics removal and must be accompanied by appropriate plans and specifications.

Module 12: Chemicals and Chemical Handling (3900-PM-BSDW0254M)
Module 12 is used to assess general information regarding chemicals. The module identifies the chemicals used and how they will be handled and introduced into the system.

Module 13: Pumping Stations (3900-PM-BSDW0254N)
