Boston, MA – Practical Applications, Inc. (PAI), a leading environmental company, recently commissioned the chemical/biological decontamination system (chemical kill system) at the Center For Medical Science in Albany, NY.

Center For Medical Science Chemical Decontamination System Tanks

Center For Medical Science Chemical Decontamination System Control Station

Capable of treating up to 28,000 gallons of waste water per day, the system is intended to operate automatically and is a duplex system, utilizing two complete treatment tanks so there is always one tank online to receive waste water. A centralized main control panel provides system control components for both tanks. Operator interaction is limited to daily inspections and maintenance procedures. The system will automatically batch process and discharge biologically inactive waste water. A vacuum collection system will gravity drain the waste water into the system. The chemical kill system enters treatment mode once the batch tank reaches an operator specified level. The waste water is mixed with chemical reagents until the ORP and pH set points are reached. The system then maintains that set point for a specific dwell time before discharging the contents to the sewer. The tank discharge is monitored for flow and residual chlorine concentration. PAI has incorporated its expert knowledge into the system’s computerized control such that numerous parameters are monitored to provide safe operation and predictive maintenance.

PAI has been designing, building, and operating waste water treatment systems since 1994. Our systems are designed and built by operating engineers and technicians who understand that an effective system must ensure performance while remaining economical to operate and maintain.

The cost for the TCH course, meals and the harbor boat cruise is $800 per person.

The Deer Island tour is FREE.

You will earn up to 5 TCHs for this course. PAI will be conducting the workshops on board one of Boston Harbor Tours’ boats. Breakfast and lunch will be served on board. After the course is complete we will dock at Deer Island and take a tour of the grounds and treatment plant. The Deer Island tour will be run by MWRA staff, and is sponsored by WOOMA, the non-profit Wastewater Operators of Massachusetts Association.

The cost for the TCH course, meals and the harbor boat cruise is $800 per person.

The Deer Island tour is FREE. If you would like to attend ONLY the Deer Island tour, and not earn any TCHs, you are welcome to find transportation to the island and join our group for the tour.

Wastewater generated during food manufacturing operations is controlled using Dissolved Air Flotation. Designed to meet strict Massachusetts sewer discharge limits, wastewater in the system is continuously treated at 50,000 gallons per day with peak flows of 200 gallons per minute.

Composed of a 12,000 gallon equalization tank, pH Neutralization controls, coagulant and polymer dosing, rotary drum screening, and sludge dewatering, the system incorporates PAI’s automatic control package and integrated expert knowledge software to predict and prevent system upset. The system is housed in a custom-built 400 square foot packaged steel building.

PAI has been designing, building, and operating wastewater treatment systems since 1994. Our systems are designed and built by operating engineers and technicians who understand that an effective system must ensure performance while remaining economical to operate and maintain.

The next session begins on June 16th and continues for 8 weeks. You may attend any or all of the classes for this session, or combine them with the classes remaining in session one. Register today at our Wastewater Operator Training registration page.

MA Wastewater Operator Exam Training

The Practical Applications industry-leading Wastewater Operator Training Exam Prep Course will be held for 8 weeks this Autumn.
Participants will be introduced to every element of the state exam, run by the New England Interstate Water Pollution Control Commission (NEIWPCC).
The course is held on Thursday mornings from 8:00 to 11:00 at Practical Applications’ South Boston training center, starting on October 1 and concluding on November 19. The state exam will be held in multiple locations on Saturday, November 21.

Boston, MA – Practical Applications, Inc. (PAI), a leading environmental company, has been awarded the contract to design and build the central wastewater treatment system for the new David H. Koch Institute for Integrative Cancer Research At MIT. The system is designed to treat wastewater flows continuously at 215,000 GPD (gallons per day) with peak flows at 300 GPM (gallons per minute).
The system employs pH neutralization/pH adjustment to control wastewater generated from laboratory research activities. The system is designed to meet strict compliance discharge limits according to Massachusetts Water Resources Authority (MWRA) sewer discharge regulations.

Our courses are approved by the Board of Certification of Wastewater Treatment Plant Operators for Training Contact Hours. Our courses are run by industry leaders who have successfully prepared professionals for over ten years. Our chemistry professional, Mr. Martins, has been with our company for over 20 sessions and has extensive industry specific knowledge.

Current MA regulations require licensed Wastewater Treatment Operators to obtain 20 TCHs due at the end of each odd year.

As discussed in the August Newsletter, a Fully Automated Industrial Wastewater Pretreatment System will shutdown and temporarily holds wastewater for proper treatment if an out-of-spec condition, an excursion, is detected. These systems require checks only twice a week and an operator on-call. All other systems require a daily operator inspection.

Fortunately, a well designed system requires minimal time and attention to maintain proper function. Maintaining the system safety, chemical inventory, cleaning and calibrating the pH sensor are the most critical daily pH system operator responsibilities. A daily 2-stage active pH Neutralization System daily system check should include:

• Get a general feeling for the system operation. Are there any observable leaks or safety hazards? Is the system louder than normal? Are the pH analyzer/controller currently operating as required?
• Next review the data recorder. Has there been an excursion since the last check? If there has been an excursions system troubleshooting is required.
• Fill out all required paperwork including daily totalized flow and any excursion details (duration and the maximum out-of-spec pH).
• Check the mixers. Are they functioning as expected, or are they hotter or louder than normal? Is the tank agitating sufficiently?
• Check the chemical level in each dispensing drum or day tank. Is there enough chemical, or should more be ordered?
• Ensure the chemical metering pumps are powered and primed. Energize the pumps and use the pH analyzer control to simulate a pH value at which the pumps should respond. Observe the pump injecting chemical into the tank. Does the pH change after exiting the simulation mode?
• Confirm the pH sensors are clean and calibrated to detect changes in pH quickly. Clean the sensors as frequently as required, usually weekly. Check the pH calibration; if the measurement is off calibrate the sensor. A drifting pH reading is a good indication that a pH probe replacement is required.

If this process is followed daily, an Operator can predict when preventive maintenance is needed. If each item on this list is completed daily your pH Neutralization System will always operate as efficiently as it was designed.
