RO MEMBRANE MANAGEMENT SPECIFICATIONS:

26.0. OFFSITE CLEANINGS:

Cleanings will involve separate steps for each foulant to be removed. They are listed below, and specific procedures will be followed, based on the type of fouling the membrane is experiencing:

- Acid cleaning to remove scale

- Caustic cleaning to remove organic material and bacteria

- Biocides and Non-Foaming surfactants to remove bacteria slime

- Chelating agents for special circumstances

Membranes must be flow, and pressure tested to ensure they meet some passing criteria before being returned to the University.

Subcontractors are not allowed. In house membrane management is required for quality control assurance.

Two references are required of other customers using RO membrane management.

27.0 RO (Reverse Osmosis) Scale Inhibitor

The RO Scale inhibitor program must be a polymer, phosphonate-based scale inhibitor proven to be compatible with DOW Filmtec membranes. Control is to be gauged using an active polymer test.

28.0 RO Clean-in-place (CIP)

RO CIPs are the responsibility of the water treatment provider. Chemicals and labor to perform the required cleanings shall be included in the bid. Acid cleaners must include surfactant, chelant, or other additives to properly remove mineral / iron scale deposits. Caustic cleaners must include surfactants, chelants, or other additives to properly remove organic / biological deposits.
