Acid Neutralization Tanks
For pH Adjustment, Acid Waste Treatment, Acid Neutralization,

Wastech acid neutralization tanks have years of proven suitability in handling tough effluents. Our line of polyethylene (PE) and polypropylene (PP) neutralization tanks are designed to withstand the heat of neutralization, the corrosive attack of acids, bases, toxics or other types of chemical wastes and the weight of mixers and pumps. The variety of tank options can be seen in the OMEGA Acid & Caustic Waste Neutralization Packages and LabDELTA Laboratory Waste Treatment Solutions. See OMEGA Neutralization System Features.

 Function

Wastech neutralization tanks are designed to facilitate the dilution and neutralization of harmful wastes that may be discharged from laboratories, industrial processes or other polluting sources. These tanks are also useful as equalization tanks for diluting polluted effluent destined for chemical treatment plants or municipal water treatment facilities by reducing the burden placed on these plants.

 Construction

Wastech neutralization tanks are either cylindrical rotationally molded with fabricated and gasketed PP covers, or are custom designed and fabricated from PP sheet.

Each rotationally molded tank is engineered to be strong enough for bulk limestone and hot liquid waste (not to exceed 140F.) Covers are strong enough for mixer mounting and include inspection ports with clear, bolted covers. Gaskets are neoprene. Tanks will include inlets for pH probes and sensors, outlets and vents as specified. These tanks are designed for industrial applications and, if installed correctly, will not collapse with normal loading. Mixer or equipment bridges are available.

Fabricated tanks are custom designed for industrial applications using 1/2” or 3/4” PP sheet. Also available is flame retardant sheet. Steel reinforcing rings are provided as needed and can be external to the tank or integral and enclosed in PP. Each tank is mounted on a PP or steel skid for forklift maneuverability. Lift points or lugs can be requested. Seismic Zone 4 designs are also available with PE certifications. Flanged inlet and outlets, sensor fittings, manholes and viewing ports are provided.

All neutralization tanks can be double-contained. Two-wall construction offers additional security from leaking. Leak detection sensors are provided as requested. Leak paths are avoided with top loading sensors and equipment.

 Operation

The neutralization medium can be limestone chips, 1"-3" diameter, liquid acid, or caustic. In limestone operations, the acids percolate up through the limestone and are chemically neutralized into salts, water and carbon dioxide. When acid or caustic is used, chemical metering pumps with double contained tubing is used. Exothermic reactions are always possible. In extreme cases, PVDF heat exchangers can be added for cooling.

Caution: There are many variables affecting neutralization and dilution of chemicals discharged through a system. Professional Wastech engineering assistance should be employed in analyzing the effluent and recommending the appropriate equipment and maintenance services.

Note: Neutralization media or chemicals are not included in tank quotations.
