Product Description

Hydrated lime, also known as calcium hydroxide (Ca(OH)2), is formed by the reaction of quicklime with water. It is a highly alkaline compound. It is often used to improve soil and the sewage generated in the production process of factories. Some water bodies are acidic. Sprinkle slaked lime in the treatment tank to neutralize the acid. Because slaked lime is cheaper for economic reasons, the factory uses slaked lime to treat acidic wastewater.

Synonyms:  Calcium Hydroxide, Slaked Lime, Lime Powder, Ash Calcium Powder.

1. Application

(1) Hydrated lime, as a neutralizer in water treatment, neutralizes and consumes acidic substances. It is also used for phosphorus removal (calcium ions and phosphate roots produce calcium phosphate precipitation), the cost is 1/3 of the caustic soda, the solubility is good.

(2) Hydrated lime is used to neutralize acidic substances in wastewater and increase the PH value of water.

(3) Widely used in metallurgical cosolvent, chemical industry, papermaking, water treatment, sewage purification treatment, tanning, rubber, plastic filling additives, thermal power plant desulfurization, flue gas desulfurization, deacidification, removal of phosphate and most heavy metals and other industries.

3.How to Use

Wet dosing: First, make it up to 5%-10% solution with continuous and mechanical stir. Add to waste water after it completely mixed into suspension and turbid liquid until the pH reaches target value.

Dry dosing: Add it directly to the reaction pool, and control dosing through the pH value. This method is suitable for dealing with strong acidic sewage by adjusting its pH value to rough expected value with the product’s strong alkalinity.

4. Packing, Storage and transportation

Packed in 25 kg woven bag or Ton bag packaging.

Stored in dry, cool and ventilate place, it will keep good for 6 months.
