Model Series CLO -Chlorination Plants

This system is generally preferred for low cost management and ease of handling compared to other chemicals.
 
Among the most widely used systems for this purpose, NALDI Ecologia has been using two solutions for many years:

• chlorine tablets
• sodium hypochlorite in solution

 The choice of one or the other system depends essentially on the size of the treatment line in question and more significantly on the peculiarities of the settlement to be subjected to purification treatment, in function of requests from local health authorities.
 
The adoption of the tablets is certainly the most simplistic solution from a technological point of view, while maintaining a decidedly effective performance. The effluent, now purified, in the passage from the reactor to the contact tank, laps the solid tablet that disinfects it, completing the purifying process with the removal of any bacteria present (coliforms, streptococci).
 
The choice of sodium hypochlorite involves the adoption of a more articulated dosing system with the possibility of going up to high performance systems where, at the explicit request of the client or, in some cases, where necessary, on the advice of NALDI Ecology, it is possible, if not necessary to provide support, a more or less sophisticated control system.
 
Sodium hypochlorite is a liquid, clear, straw-colored, antimicrobial compound with a specific weight of 1,2 kg / l.

The product present on the market which is normally used for water chlorination is a solution of sodium hypochlorite at 12-13% by volume equal to about 10% by weight of active chlorine.

(Domestic bleach contains about 5 percent sodium hypochlorite).

The addition of chlorine in water produces hydrochloric and hypochlorous acid: these compounds are known as free chlorine.
