Fluid disinfection system

A fluid disinfection unit comprising:

• a chamber having a fluid inlet, a fluid outlet, and a removable end and an opposite end;
• a radiation unit disposed in said chamber and having a radiation lamp surrounded by a sleeve;
• an electrical connector coupled to one end of said sleeve and disposed at said removable end of the chamber;
• and
• a spring having a first diameter less than a diameter of said sleeve, and a second diameter greater than a diameter of said sleeve, said spring disposed at the opposite end of said chamber for receiving and cushioning a second end of said sleeve.

A fluid disinfection unit comprising (i) a fluid treatment housing, (ii) an electrical supply module, and (iii) electrical connection means connecting the fluid treatment housing and the electrical supply module:

• (i) the fluid treatment housing comprising a fluid inlet and a fluid outlet in communication with a reaction chamber, an ultraviolet radiation lamp disposed in the reaction chamber and having a first electrical connection means at a first end of said lamp, the second end of said lamp being received and held in place by a fixture means;
• (ii) the electrical supply module comprising ballast means and a second electrical connection means;
• (iii) the electrical connection means comprising lamp connector means for removable connection to said first electrical connection means, and ballast connector means for connection to said second electrical connection means;
• and
• (iv) said fixture means comprising a tapered helical spring having a first portion with a diameter slightly less than that of the reaction chamber, a second portion having a decreasing diameter, and a third portion having a substantially constant diameter which is slightly larger than that of said lamp.
