Packaged pH Adjustment Systems |

Illustrated here is our batchTREAT BT60 pH System with standard options. (Note: This system is configured for outdoor use in direct sunlight, in the desert southwest. All tanks and piping are UV stabilized / protected).
| System Performance Specifications : | Influent Characteristics : Flow 0-250, 60 GPM Nominal Flow. Influent pH 0-14 pH units. Temperature 32-140 F. Effluent Characteristics : Flow, Discharged in batch volumes of up to 700 gallons / batch at flows up to 250 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. |

pH Adjustment systems are designed to handle a
variety of highly acidic and highly alkaline waste streams. Any acidic
or alkaline stream generated can be neutralized with a batchTREAT
pH adjustment system.
The BT60 displayed here is the most popular of the batchTREAT systems and is capable of treating flows up to 40 gpm, average flow. This family of pH adjustment systems can handle flows up to 1,000 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 effluent flows of highly acidic or highly alkaline effluents, although they can be utilized for effluent chemistries of any nature. |

| Utilities, Weight, Dimensions : | Electrical : 480VAC, 3phase,
60hz, 20 amp. Disconnect not required, provided on MCP. Air : Less than 1 SCFM @ 80 PSIG. No special requirements for air quality. Dimensions : 72" x 144" x 96"(h). 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. 2,300 lbs. dry. (not inc. shipping crate).

| The system is supplied as a completely fabricated "turnkey" package. Therefore all devices are wired and plumbed upon shipping. There is a single electrical connection point for incoming power, no further terminations are required. The disconnect on the MCP provides OSHA Lock Out / Tag Out and NFPA 79 compliance. Likewise for air, only one termination point is provided and required and a valve is supplied for OSHA LOTO.. The actual air flow requirements are quite low. | |
| Construction: |
Skid : A steel skid is provided
for supporting the entire system. The skid features a welded 4" Steel
"C" channel frame, a 1/4" steel deck plate, and a 1-1/2" box tube
frame. Pipe and conduit supports are provided by heavy duty kindorf rails. The entire skid
is bead blasted, primed, and coated with a 2 part epoxy finish for corrosion resistance.
The skid color is normally OSHA Safety Blue unless otherwise specified. Containment Pan : A Polypropylene (PP) containment / drip pan is provided for insulating the steel skid from leaking or spilled corrosive fluids and for containment of leaks. A floor drain is provided for draining the containment pan to a sump. The pan is fabricated from 1/2" PP and features 8" high walls. 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. |
Process Description : This pH Neutralization system is designed as a batch treatment system designed to accept batches ranging in volume from 50 to 700 gallons. In order to allow for continuous flow to the system a first stage equalization tank (not shown in the picture) is used. A continuous output bubbler level sensor is used in the equalization tank and the treatment tank. A Programmable Logic Controller (PLC) within the Main Control Panel (MCP) monitors the equalization tank level. When the level rises above the 10% full mark a recirculation / transfer pump is started. If the treatment tank is empty the equalization system automatically transfers a batch of up to 700 gallons (if it is available) to the treatment tank. Once the treatment tank fills to the high level the transfer from the equalization tank stops and the equalization tank reverts back to the recirculation mode. The treatment tank then treats the tank contents using our "Optimized Batch Treatment" technology developed by Digital Analysis. For additional information on "Optimization Technology" contact us and request our technical brief on this subject. Once the treatment tank contents are within the acceptable discharge range and meet all discharge criteria then discharge commences. When the treatment tank descends to the 10% full level transfer from the first stage equalization resumes and the process repeats.
On most systems a pretreatment option is provided for the equalization tank. This option allows for coarse treatment of the equalization tank contents when highly acidic or alkaline materials are present.
Application : A system of this design architecture is very versatile in that it can handle large flows when the influent chemistry is mild and can handle very concentrated effluent streams and accidental spills. This system is normally used in applications that can see widely varying flows and widely varying influent chemistries. For flows from 1GPM up to 40 GPM our prepackaged pHASE line of equipment usually perform just fine. For higher flows, or effluent streams with the potential of high volume, highly concentrated discharges a system from our batchTREAT family of pH adjustment systems is used.
Additional Information : For specific equipment information contact us directly. We can provide the specifying engineer with a formatted specification package that thoroughly describes any of our systems for bidding purposes. This includes detailed drawings, and detailed equipment specifications.
