Machinery Processing Wastewater Treatment Equipment refers to specialized systems and devices used to treat wastewater produced during machinery manufacturing, metal processing, and related industrial operations before it is discharged or reused.
This type of wastewater often contains:
Oil and grease (from lubrication and cooling fluids).
Metal shavings and suspended solids (from cutting, grinding, polishing).
Heavy metals (such as chromium, nickel, zinc, lead).
Chemical residues (degreasers, detergents, solvents, acids, alkalis).
High turbidity and chemical oxygen demand (COD) due to industrial by-products.
Typical machinery processing wastewater treatment equipment includes:
1. Pre-treatment units – oil-water separators, sedimentation tanks, and screens to remove large particles and floating oil.
2. Physical-chemical treatment systems – coagulation, flocculation, and dissolved air flotation (DAF) to remove suspended solids and emulsified oils.
3. Heavy metal removal units – precipitation, ion exchange, or membrane filtration to capture dissolved metals.
4. Biological treatment systems – aerobic or anaerobic processes (where applicable) to reduce organic load.
5. Advanced treatment units – ultrafiltration (UF), nanofiltration (NF), or reverse osmosis (RO) for final polishing and water recycling.
6. Sludge treatment systems – for safe handling, dewatering, and disposal of solid waste.
The main purpose is to meet strict industrial discharge standards, recover valuable materials, protect the environment, and enable water reuse within the production process.
