Audit | Official inspection of processes and measures in place by the manufacturing or operating site to prevent biocarrier loss |
Biocarrier | Plastic support for bacterial growth used in fluidised bed biological treatment processes (MBBR, etc) |
Life cycle | Sequence of steps from biocarrier production to their final use |
Preventive measures | All protocols and installations intended to preclude the risk of loss of biocarrier to the natural environment |
Leakage | Unintentional loss of biocarriers into the natural environment |
Stakeholders | All institutions, project owners and their subcontractors, and any organisation that may be involved in the biocarrier life cycle |
Spill | Discharge of untreated wastewater into the natural environment. It may also involve the discharge of untreated industrial water into the municipal sewer system. |
Discharge | Release of treated wastewater into the natural environment. |
Basin | Storage space for effluent during the treatment process, usually open |
Tank | Same function as a basin but usually closed |
Biofilm | A multicellular community of bacterial micro-organisms adhering to each other & to a surface and marked by the secretion of an adhesive and protective matrix. It is usually formed in water or in an aqueous medium. |
Production site | The industrial site where biocarriers are produced. |
Transport | Long-distance transport between the production site and the storage site. |
Storage site | Any area where biocarriers can be stored in large quantities and for long periods. It can be located inside the production site, on the transport platform, or in the Wastewater Treatment Plant enclosure before being introduced into the tanks. |
Handling | Means used to move or transport containers over short distances, to fill or pour biocarriers. |
