Redox Environment B.V. at Winterswijk, The netherlands, has developped a total process for waterrecycling for municipal and office buildings, laoding stations, small municipalities,etc., etc,.

7. SOURCES & APPLICATIONS

10. SBR Overview

11. Wastewater fills the tank, mixing with biomass that settles during the previous cycle Air is added to the tank to aid biologial growth and facilitate subsequent waste reduction Mixing and aeration stop during this stage to allow solids to settle to the bottom of the tank Clarified effluent is discharged. If necessary, sludge removal occurs during this stage.

16. Fine bubble diffuser aeration

19. Typical SBR application SBR wastewater treatment system installed at ski resort, high in the mountains, in Switzerland.

21. Typical SBR application Three (3) x 500 p.e. prefab systems to treat sewage at drilling and production sites of Petroleum Development Oman (PDO). The systems are designed to operate at outside temperatures of : 40 0 C in daylight time and < 5 0 C at night time. Effluent BOD: ≤ 15 mg/l.

23. UV Disinfection solutions can be used in conjunction with the following types of domestic sewage treatment plants: (amongst others ) Sequential Batch Reactor (SBR) - also designed to provide full biological treatment to crude sewage produced in a normal domestic environment. These units are usually installed in situations where there is no public sewer and where a septic tank or equal is not environmentally acceptable Process scheme of WWTP followed by UV radiation
