Wastewater must be neutralized to adjust its pH value. Only by doing this, it can meet the requirements of different processing units within a wastewater treatment system.
Neutralization may be used to treat acid wastewaters containing metals. Adding an alkaline reagent increases the pH of the acid waste. This forms a precipitate that collects unwanted metals. The result is an incoming solution of which the pH has been adjusted to the optimum range for precipitating metals as hydroxides.
Neutralac® SLS45 represents an excellent example of the Lhoist’s R&D approach to the development of innovative solutions. As a fast-acting, ready-to-use suspension of 45% solids, it is delivered at a viscosity below 300 cPs.
Featuring high reactivity (KIWA T90 < 5 sec), it is ideal for rapid acid neutralization and is also proficient at maintaining a steady pH.
Neutralac® SLS45 is more advanced than other liquid lime currently available on the market and is capable of performance comparable to caustic soda. In many cases, the use of Neutralac® SLS45 improves the precipitation of heavy metals, flocculant stability and filter cake moisture content and porosity.
