Practical Applications, Inc. (PAI), a leading environmental engineering company, announces delivery of a water reclamation system to be installed at the future Sports and Recreation Center at Worcester Polytechnic Institute (WPI) in Worcester, MA. The system’s innovative design to reuse rainwater from the roof of the new LEED-certified center supports “WPI’s commitment to environmental sustainability.”

Worcester Polytechnic Institute Greywater System

The PAI Model 1860 Greywater System operates either manually or automatically from a straightforward main control panel with up-to-date system information and current alarm status. Rainwater is collected in a main reservoir and then pumped via one of two feed pumps through a Spears inlet suction strainer to remove large particulate matter such as roofing material and leaves. The strained water is then pumped through the Micro-Z inline multimedia filter which removes most of the suspended solids. The filtered greywater will be used in WPI’s cooling towers.

Space for new construction is often a premium and successful greywater projects such as this one will include appropriately-sized tanks to recover the maximum water amount yet minimize the tank’s footprint. The tanks for PAI’s greywater system “will collect 50,000 gallons of rainwater from the roof for the cooling system, reducing the building’s water consumption by more than 800,000 gallons per year.” WPI will be getting a system that fits their space as well as their budget.

Keeping costs low by choosing the right greywater system is also a concern for businesses. The Model 1860 Greywater System has a return on investment that has a payback of less than two years. For organizations like WPI who need to keep costs low that means they can be economically as well as environmentally smart. Janice Markey, executive vice-president of PAI explains, “The cost of water has gotten to the point where it makes sense to build these things now. Fifteen years ago it didn’t, but the cost is catching up to the environmental needs. It’s great because now businesses like WPI can be environmentally sensible and save their companies money.”

Practical Applications, Inc. has been designing, building, and operating wastewater treatment systems since 1994. Operating engineers and technicians design and build effective systems that provide optimal performance while remaining economical and competitive.

Boston, MA – Practical Applications, Inc. (PAI), a leading environmental company, has designed and built a Metal Precipitation System for SPIECAPAG, a subsidiary of ENTREPOSE Contracting. Esso Highlands Limited (a subsidiary of Exxon Mobil Corporation) is the operator of the Papua New Guinea Liquefied Natural Gas Project (PNG LNG) and will use the system to treat wastewater from the PNG LNG Project.

The PAI 1878 pH Adjustment and Metal Precipitation skid-mounted batch reactor is designed to treat alkaline and acid wastewater with heavy metal contaminants. The pH is adjusted in the final sequence to achieve the permissible discharge limits.
The portable, skid-mounted system is composed of the following equipment: one conical reactor vessel, one mixer, four chemical suction stations, four metering pumps two pH/temperature sensors, one pH analyzer, one flow meter with flow totalization, two electrically-actuated ball valves, two continuous capacitance level sensors (one operating and one spare), four drum low-level detector indicators, two spill containment pads, and one main control panel. The Metal Precipitation System is completely wired and plumbed for use, with only minor modifications required on-site. Likewise, the chemical metering pumps are cord and plug connected to allow for maintenance and easy set-up.

The PAI 1878 Metal Precipitation System is designed to operate automatically in batch processing mode. The Operator Interface Terminal (OIT) displays the tank pH, effluent pH and flow. The OIT tracks the number of batches the reactor has processed, allows for user modification of set points, and indicates alarm/abnormal conditions. The system is designed to operate automatically with only minimal operator interaction beyond reagent refill and inspections/maintenance.

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 competitive.

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.

Boston, MA – Practical Applications, Inc. (PAI), a leading environmental company, has designed and built the greywater reclamation system at Bridgewater State University’s Marshall Conant Science Building in Bridgewater, MA.

Designed to treat rainwater collected from roof leaders, the greywater is required to be filtered and disinfected with chlorine prior to being used for non-potable use in the building. The system is composed of the following equipment: (1)-Bag strainer, (2) feed pumps, (2) bag filters, (1) chlorine feeder, (1) chlorine analyzers, (1) flow meter, (1) expansion tank , (1) Dye Addition metering pump, (1) Operator Interface terminal, (1) Allen Bradley PLC, and (1) main control panel.

The greywater system operates by drawing rainwater from an external cistern into the system by one of the two feed pumps. Large particulate matter is removed by the inlet suction strainer then the water is pressurized and pumped through two bag filters in series which removes most of the suspended solids.
