Abstract
An ultra-violet wastewater disinfection system is disclosed in which wastewater flows through a treatment chamber having a plurality of tube-type ultra-violet lamps in a parallel array supported therein at an acute angle with respect to the flow of wastewater through the treatment chamber. In this configuration, the wastewater flows through the array of lamps regardless of the depth of the water in the treatment chamber. The wet/dry configuration wherein a portion of the lamps is submerged and a portion of the lamps is not submerged provides very desirable results in terms of the kill rate of fecal coliform present in wastewater.
Claims17
A wastewater disinfection system, comprising:
- a flow-through treatment chamber for treating wastewater, said chamber having an inlet end and an outlet end for the wastewater;
- and
- a plurality of tube-type ultra-violet lamps positioned in a parallel array within said treatment chamber during operation of the system, said array of lamps disposed at an acute angle with respect to and transverse to the flow of the wastewater therethrough so that the wastewater passes through said array of ultra-violet lamps as it flows through said treatment chamber and is thereby disinfected, said array of lamps serves the dual functions of disinfecting the wastewater and acting as a flow control baffle to directionalize the wastewater flow.
A wastewater disinfection system, comprising:
- a flow-through treatment chamber for treating wastewater, said chamber having an inlet end and an outlet end for the wastewater and a bottom surface;
- a plurality of tube-type ultra-violet lamps positioned in a parallel array within said treatment chamber during operation of the system, said array of lamps disposed at an acute angle with respect to and transverse to the flow of the wastewater therethrough so that the wastewater passes through said array of ultra-violet lamps as it flows through said treatment chamber and is thereby disinfected, and
- at least a portion of said bottom surface is angled and disposed substantially parallel to said ultra-violet lamps.
A wastewater disinfection system, comprising:
- a flow-through treatment chamber for treating wastewater, said chamber having an inlet end and an outlet end for the wastewater;
- a plurality of tube-type ultra-violet lamps positioned in a parallel array within said treatment chamber during operation of the system, said array of lamps disposed at an acute angle with respect to the flow of wastewater through said chamber so that the lower end of each of said lamps is adjacent said outlet end of said chamber and the upper end of each of said lamps is adjacent said inlet end of said chamber during operation of the system, whereby the wastewater passes through said array of ultra-violet lamps as it flows through said treatment chamber and is thereby disinfected;
- rack means for supporting said array of lamps in said treatment chamber at the desired angle, said rack means being suspended from said lid such that said rack means and said array of lamps are lifted from said chamber when said lid is pivoted to an open position, thereby facilitating cleaning said lamps;
- and
- means for controlling the operation of said system.
A wastewater disinfection system, comprising:
- a flow-through treatment chamber for treating wastewater, said chamber having an inlet end and an outlet end for the wastewater and a hingedly mounted lid;
- a plurality of tube-type ultra-violet lamps positioned in a parallel array within said treatment chamber during operation of the system, said array of lamps disposed at an acute angle with respect to the flow of the wastewater therethrough so that the wastewater passes through said array of ultra-violet lamps as it flows through said treatment chamber and is thereby disinfected;
- and
- rack means for supporting said array of lamps in said treatment chamber at the desired angle, said rack means being suspended from said lid such that said rack means and said array of lamps are lifted from said chamber when said lid is pivoted to an open position, thereby facilitating cleaning said lamps.
