  • Wet particulate neutralizing canister for liquid acid vacuum recovery
    Patent number: 9314738
    Abstract: Devices and methods are provided for vacuum recovery of hazardous acidic liquids. A novel neutralizing canister (100) passes liquid recovery air through a bed of a combination of solid neutralizing particles (30) and water. The velocity of the air is sufficient to lift the water from the bed and highly agitate and aerate the water. At the same time, the water is allowed to circulate through the neutralizing particles (30) to maintain a high pH. This action increases the effectiveness of the neutralizing particles (30) such that the air leaving the canister (100) is entirely neutralized and harmless to persons and equipment.
