Wastewater Headworks Treatment
The headworks treatment reduces the level of pollutants in the incoming domestic and industrial wastewater to a level suitable for further treatment to ensure that the complex treatment of physical, chemical, and biological processes work effectively and efficiently.
The headworks treatment includes screening, oil removal, clarifications, other chemicals, and physical processes that help the influent wastewater to be suitable for further treatment and protect the downstream treatment from abrasion and clogging. The following systems are widely used:
- Primary treatment – wastewater screens
- Coarse screening and grinding
- Bar screening
- Fine headworks screens
- Washing and compacting
- Combined grease, oil, sand & grit removal
The Dementalization process is a cyclic process, thus, regeneration using acid & caustic soda is required at a specific frequency based on the ionic load, ion exchange quantity and flow rate. The standard system consists of Pretreatment to ensure feed water TSS is less than < 5 ppm, with a wide range of feed water conductivity up to 1,000 μm, two mono beds (SAC & SBA) followed by a mixed bed. Based on the feed water quality, a degasifier might be considered between the mono bids to reduce carbon dioxide load.
FEATURES & BENEFITS
- Protect equipment from large objects at the headworks
- Cost-effective alternative to traditional technologies
- Fine Screening primary treatment strategies safeguard sensitive equipment like MBRs
- Screening, Washing & Compacting separate fecal materials from inorganics and produce a clean, dry and compacted product of screenings
- Reduce sludge handling
APPLICATIONS
- Screening industrial wastewater containing high level of oil, suspended solids, ammonia
- Fine Screening primary treatment strategies safeguard sensitive equipment like MBRs
- Screening, Washing & Compacting separate fecal materials from inorganics and produce a clean, dry, and compacted product of screenings
