When the Clean Water Act was enacted, one of the intentions of this legislation was to reduce the untreated industrial wastewater burden on Publicly Owned Wastewater Treatment (POTW) plants in the same manner that industrial wastewater would only load the treatment plant to the same extent as ordinary household sanitary waste.

Industrial facilities that generated process wastewater had to begin pre-treatment of the water before it could be returned to the local POTW. They had to test for heavy metals, chemical oxygen demand, biological oxygen demand, pH, solvents and other chemicals that were contained in the wastewater stream and then treat to ensure removal of the contaminants.

The Clean Water Act also established limits on water discharged to the environment from an industrial facility property or discharged upon the grounds of the facility. There are many aspects of the Act that limit and seek to control hazardous chemical discharges.

Among the chemicals and oxygen demand levels prohibited to be returned without treatment or discharged, the Act also defined the pH limits of discharges to the environment to the point that any waste with a pH of 9.0 or higher was by definition hazardous waste. The act regulated and set limits on total suspended solids in the water being discharged, but left the actual limits up to the local and state agencies that administer the Clean Water Act on behalf of the Federal EPA.

The above limits on pH and total suspended solids has had an impact on ready mix and precast concrete producers. Many of the concrete production plants generate large amounts of high pH process water from rinsing and cleaning of equipment.  High pH water comes from rinsing the drums on the mixer trucks after returning from a delivery and from rinsing the exterior of the trucks after loading at the batch plant.

Storm water adds to the problem as this water can drain into the basins designed to contain and settle out the cementitious solids. The storm water becomes high pH process water at that point.

The high pH process water also contains dissolved solids and suspended solids that do not settle outin the basins. These solids are generally not removed by filtration especially the dissolved solids.

In addition, many of the job sites receiving the loads of concrete no longer allow the rinsing of the mixer trucks so the amount of concrete brought back to the production plant has been increased.

Whenever possible, the concrete producers will reuse the high pH water to batch fresh concrete. However, most state and federal paving or construction projects prohibit the reuse of the process water and specify that “Potable Water” must be used as concrete makeup water. The high pH water cannot be used for pre-wetting aggregate or dust control because it will contaminate the site.

The water may be reused for truck rinsing and cleaning provided the water is returned to the catch basins or pits.

The problem for the ready mix and to some extent the precast producers is the generation of excess process water (including storm water) that accumulates by normal business volume and specifically when the producer must use potable water in lieu of recycled water.

The producer must have an economical way to deal with this problem short of storing it or paying for it to be transported for disposal as industrial wastewater.

To simply discharge the water off the property can incur a future liability for fines but also for future fees for remediation of the property upon which the water was discharged.

In 2011, a company operating ready mixed concrete plants was fined $740,000 for violating the Clean Water Act. The company also was required to pay $8,000,000 into a remediation fund for site clean up at various locations

There are solutions available to the concrete producers:

Fortrans Inc. and BibKo NA market self-contained pH control systems that are guaranteed to solve this problem for the producers. The modestly priced systems use low cost C02 gas to automatically lower the pH of the process water and lower the total dissolved and suspended solids to meet the Clean Water Act limits for discharge to the environment.

Fortrans pH control systems can provide outstanding control and monitoring of stored process water. The treated water may be recycled for batching concrete, pumped to wash racks, used for irrigation or dust control.

Prevent EPA Fines for Discharge of High pH Process Water or Storm Water

1. Eliminate the cost of storing or disposal of excess process water
2. Treated water meets pH and total suspended solids limits for discharge
3. Fortrans systems are safer and less costly to operate than acid based systems
4. Use pH adjusted process water for recycling, rinsing trucks, dust control or irrigation
5. Simple low maintenance design
6. Reduce potable water usage
7. Low cost solution

All standard Fortrans pH Control Systems include:

• The Fortrans exclusive non-fouling carbon dioxide diffusion and injection system (patent pending) adjusts the pH of process water and/or storm water automatically, on an as-needed basis. This carbon dioxide pH adjustment system is driven by a programmable logic controller that automatically maintains a preset pH (usually pH 7.5), for water stored in your detention basin. Target pH range is adjustable. Includes pH measurement cell, and fully automated operation. The Fortrans is highly reliable, and exceptionally economical to operate.

• High efficiency stainless steel submersible pump with stainless steel impeller, thermally protected continuous-duty motor, and float assembly to protect against run-dry condition. The standard system pump yields approximately 70,000 gallons per day from a typical 12 to 15 foot deep detention basin, and has capacity to pump from basins or pits 20 feet and more in depth.

• High quality swivel pump boom, 150 lb capacity, 2 feet high, with 30″ boom reach and 1000 lb manual winch.

• 2-inch pump connection and 2-inch discharge hoses (25 feet each) with cam lock quick connect fittings for quick and easy set-up.

• Electronic flow rate meter to indicate that the system is operating within a normal flow range, or to indicate that maintenance cleaning of the pump inlet, or the system hoses, is required.

• Factory installed industrial-duty surge suppressor to protect the system electronics.

• Red light fixture to warn that the system pH has exceeded the alarm set-point..

• A system enclosure that is best suited to your facilities needs.

All systems are equipped with an electronic flow meter and a factory wired industrial Surge suppressor (2800 Joule). An installation, operation and maintenance manual is provided with each system. Factory support is also available.

The Model 5000S pH Control and Monitoring System is designed for concrete manufacturers to effectively control the pH and total suspended solids of excess process water and or storm water run-off.

As the pH is being lowered to 7.5, the dissolved and suspended solids will become insoluble and precipitate out of solution. Lab tests after pH adjustment indicate that total suspended solids are between 10-18 mg/l without filtration. This enables the facility to meet the pH requirements as well as the 30 mg/l total suspended solids limit most permits demand before the water can be released.

The treated water may be recycled to batch concrete, irrigate rock or to rinse trucks and other equipment without scaling the painted surfaces

Use of the system can reduce potable water usage.

The system will treat approximately 75,000 gallons per day utilizing the Fortrans proprietary non-fouling C02 injector diffuser. The system is powered by a stainless steel continuous duty rated submersible pump with thermal overload protection..

We are currently using 9 of the Model 5000S pH Control Systems supplied by Fortrans at our ready mix concrete plants and are very pleased with them. In fact, they are not only helping us to control the pH in our pit systems but also help us deal with the solids build-up as well. They are reliable and virtually maintenance free and one of the best methods that I have found in dealing with high pH process water which is one of the most critical and increasingly regulated issues in our industry. We currently operate 30 plants and I intend to purchase several more Model 5000S systems.“
