Mobile Wastewater Frac Tank treatment plants or emergency wastewater treatment is often required when treatment systems need cleaning, repairs or upgrades to meet stricter effluent guidelines or increased loadings.  

Remtech provides emergency mobile wastewater treatment systems that can be mobilized to your facility within hours to keep you facility in compliance when maintenance is required or a new plant is being designed, constructed or simply provide an emergency or permanent upgrade to keep your facility in compliance.

Frac Tank Aeration System with 12-50 Micron Diffuser Heads

(Offset Diffusers Creates Circular Mixing Pattern)

Remtech recently demonstrated its emergency pre-treatment facility deployment capabilities for a major food manufacturing facility when their plant failed with leaking tanks, non-functional pumps and neutralization system, and a DAF air injection system that stopped working. Regulatory authorities required that manufacturing stop until a waste treatment system was operational.

The temporary 60,000 gpd wastewater treatment system was brought online in 3 days and completed in 15 days and operated for 9 months until the permanent plant was completed.

Six (6) 20,000 gal frac tanks were mobilized to provide unit operations for the plant.  Raw wastewater was diverted to an primary 20,000 blending and solids screening tank.  A 60,000 gal equalization basin was constructed of three (3) 20,000 gal. frac tanks connected in parallel. Flow between tanks was spit equally providing a five hour retention time for flow and concentration equalization.  

Fifty (50) micron air diffuser manifolded heads were inserted through 30" manholes with connections consisting of 5 universal fittings and 85 pound anchoring magnets.  Sixteen (16) diffusers in each tank provided flow and concentration equalization and enough mixing to prevent settling of solids.  An existing 5 Hp rotary lobe blower (187 cfm @ 15 psi) provided excess air to provide uniform mixing and oxygen for biological oxidization.

Air mixing pilot tests on four diffuser heads on 34” centers required 1.3 cfm air per head at 5 psi to produce a radius of influence of 8 ft in each tank.  Available air provided three times the air required for mixing and oxidization.  Wastewater from the equalization basin flowed through a seven (7) tier 10 ft long serpentine chemical floculation/neutralization/mixing system constructed out of four-inch schedule 80 PVC that provided a 15 second contact/mixing time for acid/base/alum addition.

Chemical addition was controlled by a PID pH controller.  A new 20 micron bubble pump was installed to restore operation of the dissolved air floatation system that replaced the old compress air injection system. This pump replaced the existing compressor, pressure vessel, ejector, and static mixer.
