I.Overview
Wastewater treatment systems for the food and beverage industry need to be designed for characteristics such as high organic concentrations, suspended solids, oils and greases, and possible additives.
II.Main process
Raw water → Pre-treatment (physical separation + water conditioning) → Biological treatment (core: anaerobic + aerobic / contact oxidation combination / single selection) → Deep treatment (difficult to degrade + SS + microorganisms precise removal) → Compliant effluent
(simultaneous sludge generation goes in) Sludge treatment (reduction + resourcefulness) → Resourcefulness / Disposal
III.Core Property Parameters
| Parameter |
Typical Range/Requirement |
Significance |
| COD |
1000-10000 mg/L (Raw Water) |
Determines the selection of biological treatment processes |
| BOD₅/COD Ratio |
≥0.3 (Favorable for biodegradation) |
Assesses the biodegradability of wastewater |
| SS (Suspended Solids) |
200-2000 mg/L |
Influences the selection of pretreatment equipment |
| pH |
6-9 (After Treatment) |
Avoids corrosion or inhibition of microbial activity |
| Oil Content |
< 50 mg/L (Discharge Requirement) |
Requires air flotation or centrifugal separation |
| Ammonia Nitrogen (NH₃-N) |
< 15 mg/L (Discharge Standard) |
Requires nitrification/denitrification processes |
| Sludge Loading (F/M) |
0.1-0.4 kgBOD₅/kgMLSS·d |
Controls the operation efficiency of activated sludge systems |

VI.Here is a guideline for you to get a proper quotation
Tell us the raw water/source of water(tap water, well water, or sea water, etc)
Provide water analysis report(TDS , conductivity, or resistivity, etc)
Required production capacity( 5m³/H, 50m³/H,or 500m³/H, etc)
What's the pure water used for( industrial,Food and Beverage,or agriculture, etc )
