Food & Beverage Wastewater Treatment

High-COD, high-oil wastewater from food processing — engineered DAF systems that meet discharge limits and cut surcharges

Food factory wastewater treatment installation

Food Processing Produces Some of the Hardest Wastewater to Treat

Dairies, breweries, meat and poultry processors, beverage plants, and fruit & vegetable canneries all discharge water loaded with organic matter, fats and oils (FOG), and suspended solids. Left untreated, it fails discharge standards — triggering fines, production stoppages, or expensive municipal surcharges.

High CODTypically 1,000–20,000 mg/L depending on product
Fats & OilsEmulsified FOG that clogs and fouls downstream units
Suspended SolidsFibers, pulp, and settleable matter
Flow VariabilitySeasonal and batch production swings

A Complete Treatment Line, Engineered to Order

From pre-screening to sludge dewatering, every stage is sized to your inlet parameters and required outlet standard.

⛔

1 · Pretreatment

Mechanical bar screens and an equalization tank remove coarse solids and smooth out flow peaks.

💧

2 · DAF Clarification

Dissolved air flotation removes FOG, suspended solids, and a large share of COD before biological treatment.

♻

3 · Biological (Optional)

A/O or MBR stages polish the effluent to reach strict reuse or discharge standards.

🧲

4 · Sludge Dewatering

Belt or screw press dewaters the collected sludge to 20–35% cake solids for low-cost disposal.

The Two Machines That Do the Heavy Lifting

Dissolved Air Flotation DAF system

Dissolved Air Flotation (DAF) System

The workhorse for food wastewater. Micro-bubbles attach to fat, oil, and solids and float them to the surface, where a skimmer removes them — before they can foul your biological or membrane stages.

Flow Rate1–200 m³/h, modular design
TSS Removal≥ 90%, oil & grease ≥ 95%
COD RemovalTypically 30–60% before biological stage
MaterialSS304, SS316L, or anti-corrosion carbon steel

Sludge dewatering belt filter press

Sludge Dewatering Systems

The FOG and solids removed by the DAF become sludge. Dewater it on-site to cut haulage and disposal costs — belt press, screw press, or decanter centrifuge depending on sludge volume and type.

TypesBelt press, screw press, decanter centrifuge
Capacity0.5–10 t/h dry solids
Cake Solids20–35% depending on sludge type
ControlPLC automated with remote monitoring option

Typical System Configurations

Reference line-ups by scale — the final design depends on your exact inlet parameters and discharge target.
