High-Speed Wastewater Treatment Process
2.8 hours HRT with BBF

 

Tomorrow Water’s flagship plant at the Jungrang municipal treatment facility is one of the largest in Korea. Located in the heart of Seoul, the facility was designed as part of a water reuse center to protect the ecosystem of the Han River.

This plant has replaced primary clarifiers in its 66 MGD treatment train with underground BBF Primary filters, and added 132 MGD in additional BBF biofilters to manage wet weather flow.

This high speed filtration facility is designed so that 66% of total influent will be treated to < 40mg/L of BOD before discharge.

Most importantly, the wet weather flow treatment facility is replacing a 66MGD primary clarifier so that the City can save valuable space in its wastewater treatment facilities.

Project Purpose

  • Upgrade facilities and move treatment train underground

  • TMDL (BOD)

Project Outcomes

  • Underground construction allowed for above-ground land repurposing

  • Ecological protection

  • Reduced equipment footprint

Facility Details

  • Capacity:  132 MGD (Primary: 66 MGD)

  • Process: Pretreatment + BBF (WWF) + BBF(Secondary)

  • In operation since 2016

Primary Treatment

  • Underground treatment train

  • Modernization and retrofit

  • TMDL (BOD)

Capacity: 66 MGD

Process: BBF-F


Secondary Treatment

Underground construction

Modernization

TMDL(BOD, T-P)

Capacity: 66 MGD

Process: BBF (DND)+BBF (N)+MDF

Wet-Weather CSO Treatment

Project Purpose

  • Underground construction

CSO + Primary Treatment (simultaneously)

To conserve water, the Seoul Metropolitan Government processes discharge water from the Seonam Wastewater Reuse Plant to supply 20,000 m3/d of treated wastewater to the Magok District industrial development area.

Project Purpose:

  • Underground construction

  • Modernization

  • TMDL(BOD)

Capacity: 190 MGD

Process: BBF-F

Operating: 2017 Under Construction

BBF is used for wet weather flow control in wet season, but the same BBF system reverts to a main treatment process during dry season.

Project Outcomes

  • Conservation of water resources in the Seoul metropolitan area

  • Establishment of a positive image for Seoul as an eco-city

  • Ecological protection

  • Reducing equipment footprint in the facility

Facility Details

  • Capacity: 190 MGD| Primary : 95 MGD

  • Process: Pretreatment + BBF(WWF) + BBF(Secondary)

Project Background

  • Conducted at the Seonam WWTP (190 MGD), the largest in Asia, covering 1/3 of Seoul.

  • 58% organic loading discharged during the wet weather season.

  • 28GPM pilot test performed from 2010-2012

Song-do Wastewater Reuse Plant

A new smart city or "ubiquitous city” constructed on reclaimed land along Incheon's waterfront, the Songdo International Business District performed a demonstration project for wastewater reuse after being selected as a nationwide model for water reuse and effective water utilization.

The planned water Reuse project included installation of a treatment facility with capacity of 20,000 m3/d, 15km of pipeline, and a booster pumping station. Completed in May 2015, the system has since been supplying reclaimed water.

Project Outcomes

  • Pollution reduction in the Incheon coastal area

  • Selection of Incheon as one of 12 “Water Champion” cities by the WWC (World Water Council)

Facility Details

  • Capacity: 20,000 ㎥/d | Area: 1,571㎡)

  • Treatment process: Chemical coagulation/flocculation + Bio-filtration (BBF) + Ozone Oxidation + Disinfection
