General Background

 

This plant is a part of the regional project for the reuse of effluent in the Izra'el valley.

 

This plant serves the municipalities of Nazareth, Nazerat-Illit, Yafia and several rural villages of Izra'el regional council, having equivalent population of 150,000.

 

The plant was originally built in 1994 (1st phase) and expanded during 2003 (2nd phase).

 

At the present the plant consists of semi-intensive facilities, i.e. a combination of anaerobic and aerated earth lagoons.

 

Due to more updated and stringent regulation for the quality of the effluent to be reused in the Izra'el valley, a new B.N.R activated sludge module is now under design.

 

BJIS provided general and complete detailed design services for both phases of construction and currently designs the new B.N.T Activated sludge module.

  

Basic Design Facts:

 

  • Average Design Flow (m3/day): 15,000
  • Average B.O.D. Load (Kg/day): 7,000
  • Effluent Quality (BOD/TSS/N): 50/70/N.R.
