Boston, MA – Practical Applications, Inc. (PAI), a leading environmental company, has designed and built a state of the art pH Neutralization System for Bridgewater State University’s Marshall Conant Science Building in Bridgewater, MA.

The Practical Applications, Inc. (PAI) Model-1812 pH Neutralization System is designed to monitor and adjust the pH of wastewater prior to discharge to the city sewer system. This model will handle influent flows to a maximum of 33 gpm and consists of one baffled wastewater treatment tank, one mixer, two reagent pumps (one acid and one caustic), two reagent storage tanks with secondary containment, tank and effluent pH probes. The tank pH analyzer/controllers monitor and adjust pH in each tank between the pH set points established by the operator. The effluent probe monitors the discharge pH and uses this information to generate a permanent record on a digital chart recorder. If re-treatment is indicated, the system can activate a pH Out of Specification Alarm and divert the wastewater to a 500 gallon lift station tank containing two submersible centrifugal pumps.
A 4″ magnetic flow meter installed at the pH system outlet monitors and displays real time and totalized discharge flow rate to the city sewer. A signal from this unit is also sent to the chart recorder for a permanent record.

Bridgewater State University Marshall Conant Science Building pH System

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 optimal performance while remaining economical and easy to maintain.

We have worked with many industries to assist with their wastewater needs and we take ownership for their water systems, wastewater systems, sampling/self monitoring, and regulatory reporting so our customers can focus on their core business.

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.

Boston, MA – Leading environmental firm Practical Applications, Inc. (PAI) has been awarded the contract to build the central wastewater treatment system for the plant expansion project at Tribe Foods, Inc., a subsidiary of Nestle, SA.

Tribe Foods Wastewater Treatment System - DAF Unit supplied by Krofta

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.
