Wastewater chlorination

Some other types of treatment processes that can be employed in the hydrogen cyanide industry include ozonation, to oxidize the wastewater chlorine. Potency of sulfur oxide is also high in the oxidation process. 

Trace amounts of phenols may occur in many natural waters as well as in domestic and industrial wastewaters. Chlorination of such waters can produce chlorophenols. 

When wastewater is treated by chlorine, the treatment process is termed wastewater chlorination, or simply chlorination. ... 

Common Design Shortcomings of Wastewater Chlorination and Solutions... 

In most cases, control of breakpoint chlorination requires the use of accurate and reliable automatic equipment to reduce the need for manual process control by operators. However, the operator must give special attention to this equipment and monitoring devices in order to ensure their proper operation. Table 3 indicates how the common process shortcomings can be compensated and improved. Table 4 is a wastewater chlorination process trouble-shooting guide for use by practicing environmental engineers.

Figure 3 in introduces the Coxsackie Sewage Treatment Plant (STP). The plant s special wastewater chlorination facility, a combined chlorine contact chamber (CCC) second-phase final settler unit, is shown in Fig. 4. This section introduces the sludge chlorination facility of Coxsackie STP and its operational data. At Coxsackie STP, data generated during 19 batches of sludge chlorination are summarized in Tables 10-12. Characteristics of the underflow from the sludge dewatering beds for nine of those...

Another possibility for the formation of free radical species from hypochlorite is through its reactions with transition metal ions. Thus, Guilmet and Meunier (1980) reported a manganese-promoted epoxidation of olefins such as styrene (Equation 5.13) and cyclohexene in a two-phase dichloromethane-water solvent mixture. The epoxide oxygen was derived from HOCl, not from air, but no mechanistic details were speculated upon. Further evidence needs to be obtained on the possibility of free-radical reactions in water and wastewater chlorination. 

Hydrophobic nature, especially suitable to bind nonpolar substances, flue gas cleaning, gas cleaning, solvent recovery, deodorization, respiration filter, catalyst carrier, separation of gas mixtures, deoiling, degreasing, liquid decoloration organic substance removal from drinking water, feed water, and wastewater chlorine and ozone removal from water.
