Measuring waste water

The water waste from a winery is known to be filled with pollution. The wastewater is measured to prevent oxygen depletion in the soil and soil leaching.

The most common method of measuring the wastewater is a test called biological oxygen demand (BOD). The BOD5 test is a standardised lab analysis that measures how much oxygen is consumed over 5 days of ‘breaking down a sample’ that has been taken. This will give the winery an indication of the water quality being dispatched.

We have included a short three minute animated You tube video that explains BOD.

Suspended solids tests are also used to measure the level of various matter in the waste water. This testing can be as simple as a filtration check in the winery laboratory. This image shows how the water solution is diluted checking for bacteria
