Influent Characteristics : Flow 0-200, 60 GPM Nominal Flow. Influent pH 0-14 pH units. Temperature 32-140 F. 

Effluent Characteristics : Flow, Discharged in batch volumes of up to 500 gallons / batch at flows up to 300 gpm.  pH  Nominal discharge range is 6.50 - 8.50 pH units. (Actual discharge limit is field programmable).

Effluent Monitoring : As mandated by the local controlling authority the effluent quality must be continuously monitored. A two pen recorder is to be used to monitor effluent flow rate and pH. The recorder is to be equipped with a flow totalizer. Any effluent pH deviations will trigger an alarm and system discharge will be halted.

The system displayed here is the smallest of the pHASE systems and is capable of treating flows up to 60 gpm, average flow. This family of pH adjustment systems can handle flows up to 60 gpm. Although actual throughput is a function of water chemistry. The pHASE family of pH Adjustment systems all utilize our proprietary "Optimized Batch" pH adjustment technology.

These systems are well suited for low flows of highly acidic or highly alkaline effluents, although they can be utilized for effluent chemistries of any nature.

Air : Less than 1 SCFM @ 80 PSIG. No special requirements for air quality.

Dimensions : 44" x 84" x 62"(h) (Not including the optional influent equalization tank). Access to the front of the skid and the both sides is required for ease of service. Dimensions do not include the Main Control Panel which can be mounted anywhere on the system perimeter or a nearby wall.

Weight : Approx. 1,600 lbs. dry. (not inc. shipping crate).

Treatment Tank: The treatment tank is a custom fabricated Polypropylene  vessel.  The tank is supplied with a 2" gasketed lip for sealing the cover. Reinforcement ribs around the perimeter of the tank provides additional wall support. These ribs are fabricated from 4" Steel "C" channel and are epoxy coated and encapsulated in PP. The tank is designed for fluids with a s.g. of up to 1.9 with a safety factor of 2:1. Destructive burst testing has shown that tanks of this construction often have an ultimate load safety factor exceeding 3:1. If positive ventilation is used the tank is rated to +/- 20" w.c. The tank top is reinforced and gasketed. The top will support all mounted equipment and the weight of one 200lb. man without significant deflection. The system shown here is fabricated from Polypropylene, however, all commercially available materials are available including FRP, SST, exotic alloys and all thermoplastics.

Reagent Storage Tanks : Chemicals for treatment are pumped directly from 55 gallon DOT drums using our unique suction wands. An alternate to pumping directly from DOT drums is utilization of day tanks which can be automatically refilled from customers bulk chemical delivery system within the plant. Redundant level sensors and redundant fill valves provide protection against overfilling. 

Piping : All recirculation, transfer and discharge lines are fabricated from solvent welded PVC SCH 80 pipe. Threaded fittings are not used unless absolutely necessary. All reagent delivery lines are flexible PFA tube double contained within a clear  flexible PVC hose, clamped at each end to seal leaks. Alternate piping systems are available and commonly used.

Valves : All ball valves are true union field serviceable valves. All diaphragm valves are flange mounted. Elastomers are EPDM and Teflon except on concentrated acid lines where the elastomers are Viton and / or Teflon. Alternate piping systems are available and commonly used.

Electrical : All enclosures are NEMA 4X, where metallic enclosures are used they are provided with epoxy or polyester finishes for corrosion resistance. All conduit is plastic coated where possible. Low voltage 24VDC is used throughout to minimize service personnel exposure to high voltage. All panels are OSHA LOTO and NFPA 79 compliant, additionally UL-508 listing is available.
