WSB® clean pro plants with cylindrical tanks > 53 RE to approx. 220 RE
Plants with cylindrical tanks clarify from 53 RE to approx. 220 RE.

WSB® clean pro - design according to ATV A 122 for carbon elimination and nitrification 
1 Sludge accrual tank
 
  • According to ATV A 122:100 L/E
  • Sludge accrual time: approx. 3 - 4 months (WSB® - process)
2 Pre-clarification
 
  • t ≥ 1.5 h (safety margin if sludge storage is full)
  • => Sizing BIO with 40 g of BOD5/(E*d)
3 Biology
 
  • C-plants: 1 to 3 stages
  • N-plants: 2 to 3 stages
4 Final sedimentation
 
  • t ≤ 3 to 3.5 h
  • qA = 0,4 to 0,6 m3/(m2*h)
5 Installation for lateral channel compressor
 
  • inside
  • 1 compressor: compressor cabinet
    L x B x H = 1.000 x 500 x 1.000 mm
  • 2 compressors: container
    L x B x H = ca. 2.000 x 2.000 x 2.000 mm
  • 3 submersible motor driven compressors in the plant
6 Potential equalization
 
  • Grounding in the soil: Steel rod from stainless steel d = 10 mm
  • Grounding of the conductive parts: Steel rod from stainless steel d = 6 - 7 mm
Discharge values for plants with carbon decomposition
COD  ≥ 150 mg/l
BOD5  ≥ 40 mg/l
Discharge values for plants with carbon decomposition and nitrification
COD  ≥ 90 mg/l
BOD5  ≥ 20 mg/l
Subsequent nitrification
NH4-N  ≤ 10 mg/l
WSB® clean pro rectangular reservoir plants > 220 RE upwards
Rectangular reservoir plants bring cleaning performances from 220 RE upwards.
