The main raw materials for liquor production include wheat, glutinous rice, etc. Wastewater is generated during the production process, such as bottom pot water from distillation, water from washing the airing floor, floor washing water, and cooling water used in fermentation and distillation processes.

In addition, wastewater is also produced during production, mainly coming from the distiller’s grains discharged after the distillation of mature fermented mash. Below we will introduce the work related to Wastewater Quality Monitoring in Distilleries.

Wastewater Quality Monitoring in Distilleries can be Divided Into the Following Aspects:

1.Total discharge outlet

This is the common outlet for wastewater from different sections of the plant. More monitoring indicators are required at this outlet, including:

total phosphorus (TP), total nitrogen (TN), chemical oxygen demand (COD), flow rate, pH value, ammonia nitrogen, colority, etc.

2.Other discharge outlets

Rainwater discharge outlet: Only two indicators are monitored: suspended solids (SS) and chemical oxygen demand (COD).

Domestic sewage: Main monitoring indicators include COD, ammonia nitrogen, TP, and TN.

Monitoring must be properly carried out at all sampling points.

Different Water Quality Monitors are required for testing different parameters. Each device is usually designed for single-parameter detection.

Although 2-in-1, 3-in-1, and 4-in-1 instruments are available from Hangzhou Modi, we still recommend using single-parameter monitors, as they provide relatively more accurate test data.
