Neutralization of corrosive, toxic and flammable wastes is necessary to the environment and piping systems, even when quantities and concentrations are small. Such wastes can cause physical damage to a building’s piping or outside sewer systems and, if effluent is being discharged to the environment (such as rivers and lakes), severe damage can result to wildlife and water sources.

LAKASA Neutralization Tank is designed for intermittent flow of acidic wastewater which attempts to achieve an average retention time of > 30 minutes, as such the interaction and dilution to be taken place between the acidic wastewater and the calcium carbonate based neutralizing agent.

The chemical reaction between Calcium Carbonate and acidic waste water will produce by-products of neutralized waste, carbon dioxide and neutral salts that can be safely discharged into municipal sewer

According to the Environment Quality Act, the effluent with pH value of  5.5 to 9.0 is acceptable under its standard B requirement.

LAKASA Neutralization Tank is also called Dilution Tank, designed to receive, dilute and neutralize corrosive and harmful chemical wastes before allowing such materials to be discharged into the public sewers or the environment, is suitable for centralized installation for neutralizing and dilution of laboratory acids and chemicals.

Places recommended for useRecommended to be installed in acid waste drainage systems for medical and research laboratories, industrial battery charging stations, educational institutions and processing equipment. LAKASA Neutralization Tank is recommended for preliminary treatment for acidic wastewater.  Therefore the effluent should be channeled to nearest sewer for further process.

If the pH of water is too high or too low, the aquatic organisms living within it will die. pH can also affect the solubility and toxicity of chemicals and heavy metals in the water. The majority of aquatic creatures prefer a pH range of 6.5-9.0, though some can live in water with pH levels outside of this range. As pH levels move away from this range (up or down) it can stress animal systems and reduce hatching and survival rates. The further outside of the optimum pH range a value is, the higher the mortality rates.

Proper functioning of the LAKASA Neutralizing System requires determining water flow or the volume of incoming acidic waste water, in order to achieve sufficient retention time for the neutralizing process to take place (see figure i). The initial rate of neutralization is rapid, however, as the pH of the acid waste rises, the rate of neutralization slows down. Neutralization reaction time of more than 45 minutes should achieve a safe pH level or a level which is considered high enough to be easily diluted with sanitary waste.

Neutralization is the process whereby acids and alkalis are rendered harmless. The degree of neutralization can be measured by a system known as pH (positive Hydronium ions). The degree of measurement is a pH number of 7, which is neutral. Acids range from 0 to 6.99. Alkalis range from 7.01 to 14. The smaller the number, the higher the content of acidic waste. The higher the pH number, the higher the alkaline waste.
