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.

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.

Is There Mercury In Your Industrial Wastewater Discharge?

This article was written by Practical Applications’ biologist Kimberly Baxter and originally appeared in the December 2005 issue of Plumbing Engineer magazine. A PDF of the article is available HERE.

Abstract

An assessment of sampling locations for three industrial wastewater effluent piping systems is presented. The assessments provided demonstrate that by installing sampling ports at the appropriate location along an effluent stream’s piping system, truly representative samples can be collected. These real and accurate results scientifically prove that a specific industrial wastewater discharge does not contain mercury levels that will trigger regulatory enforcement action.

Collection, Recycling, Labeling and Sales Ban of Mercury-added Products; and Disposal Prohibition of Mercury-added Products in Solid Waste–310 CMR 19.00 (amended), 74.00 (amended), 75.00 (amended), 76.00 (added).

Brief Explanation and Rationale for Changes

Signed into law in July 2006, the “Massachusetts Mercury Management Act” is designed to keep mercury out of our trash and wastewater, where it is released into the environment. MassDEP is implementing this law in two phases. The Phase 1 regulations (promulgated on December 28, 2007) banned the sale of mercury-added products in Massachusetts unless the manufacturer registers the product with an interstate clearinghouse and establishes a collection program for the end-of-life products, banned schools from buying mercury-containing products, required auto manufacturers to collect and recycle mercury switches from “end of life” vehicles, required manufacturers of mercury containing lamps to educate consumers about mercury hazards and the requirement to recycle discarded lamps and to report on lamp recycling to MassDEP.

The Phase 2 regulations (promulgated on August 21, 2009) ban the sale in Massachusetts of specific mercury-added products, establish a procedure for manufacturers to apply for an exemption from the sales ban, and establish labeling requirements for mercury-added products that are sold in Massachusetts. The regulations also prohibit disposal of any mercury-added product in solid waste.

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.
