What industrial influent data an MBR supplier needs
Build an MBR request for quotation from wastewater loads, variability and the intended reuse.

Sample the operating cycle
An industrial influent composite can hide short production or washdown events that affect biology and membrane operation. Provide flow by shift, campaign or batch, then identify high-load cleaning periods and any intermittent sources. Include representative data for pH, temperature, solids, organic load and any relevant inhibitory compounds. Mark values that are estimated and describe how samples were taken.
Separate biological and membrane duties
An MBR couples biological treatment with membrane solids separation. Describe which contaminants must be reduced by biology or another upstream process and which filtrate properties the membrane train must achieve. State the reuse target at the final delivery point. Additional disinfection or dissolved-solids treatment may be required, depending on the use and project criteria.
Turn the design basis into a test plan
Ask the supplier for assumptions about equalization, pretreatment, membrane air scour, cleaning and sludge handling. Identify representative and challenging feed conditions for commissioning. Request a clear response if process changes move wastewater outside the agreed operating envelope.
