Dairy processing

Data Collection

We consider a hypothetical data representative of a dairy industry. The major challenge in terms of water-saving consists to reuse water from whey processing (microfiltration, reverse osmosis, and concentration). This water is considered a source (S1 and S2) that can potentially be reused in other processes.

We consider also the makeup water supplied in the cooling tower. This water is considered a sink (or demand D1) that can be supplied from the source streams.

Finally, we consider the use of water in CIPs for pre-washing (post 1) and rinsing (post 2) operations.

Inventory data is collected in the following table:

Data Collection

Workshop	Inventory	Type	water m^3/h	COD(in) ppm	COD(out) ppm	COD load kg/h
Whey processing	RO permeate S1	Source	10	–	20	–
Evaporation	Condensates S2	Source	5	–	60	–
Cooling Tower	Makeup Water D1	Sink	5	20	–	–
CIPs	Prewashing P1	Post	–	20	1000	100
CIPs	Rinsing P2	Post	–	3	30	20

New project

To add a new project, press Ctrl + N or click on New from File menu then enter the name of the project and add a description.

Add a new project

New pollutant

From the Pollutants tab, add the pollution indicator DCO (Chemical oxygen demand).

Add a new pollutant

Add inventories

Add the inventories of sources, sinks and posts, respectively from Sources, Sinks and Posts tabs. Water flowrate is expressed in m3/h, COD concentration in ppm, and COD mass load in kg/h.
