MEDIUM PRESSURE UV SMP RANGE

WASTE WATER DISINFECTION

APPLICATION

 Secondary and tertiary effluent from water treatment plants, although relatively low in BOD and suspended solids in efficiently operated installations, contains a number of pathogenic micro-organisms that can cause serious diseases in people and animals.

 Disease can be transmitted orally by ingestion of infected water, or by consumption of contaminated shellfish, or merely as a result of contact with the skin during swimming in contaminated water.

 The risk of disease is created by the discharge of infected water close to swimming areas, drinking water intakes and shellfish-farming locations or when used for agricultural purposes in the interests of water conservation.

 The incorpotation of a Medium Pressure Broad spectrum germicidal irradiation system after final filtration of treated waste water economically provides the disinfection to meet the microbial standards required for safe discharge or re-use without the use of additional chemicals, which in themselves could add to the contamination load.

 Design of the UV system must relate to the minimum UV transmissin value of the effluent and also to the peak flow.

 Industrial waste water treatment plants may incorporate a Medium Pressure UV system in conjunction with ozone. This advanced oxidation process offers a powerful water treatment combination for reduction of difficult organic compounds.

OPTIONS

 UV output monitoring system

Electronic power supply with varable control

Polished 316 s.s. control panel housing

FEATURES AND BENEFITS

 Compared with conventional low pressure mercury lamp systems the use of high intensity medium pressure models results in a dramatic reduction of numbers of lamps, space requirement and installation and lamp replacement costs.

UV radiation of broad germicidal action applied at the correct dose rate destroys the ability of pathogens to metabolise and reproduce and is successful against viruses and bacteria.

 Ozonia Triogen medium pressure U systems with high energy output per unit size are particularly applicable in this respect being specifically designed for the purpose and incorporating an automatic wiper with interval control to suit effluent quality.

 UV irradiation treatment eliminates the need for chemical handling, and storage on site, or systems for dosing chemicals into the treatment stream.

 Cost savings for smaller waste water treatment installations when compared with open channel technology.
