Powerplant Wastewater Treatment

Cromaglass is well known for use at many public and private authorities - The Chesapeake Bay Bridge/Tunnel system and several state park installations are some examples. The largest and newest of these has been the Pagbilao electric powerplant in the Philippines. A few hours drive south of Manila, this large electric generating facility chose Cromaglass based upon knowledge of several similar type projects throughout the world.

CEPA/Slipform, contractors for many major projects in the Southeast Asia Area, contacted Cromaglass in December 1994 for costs on specifications for an estimated 60,000 gpd wastewater flow.

Cromaglass engineering staff worked closely with the purchasing group and its supporting personnel to meet specifications required of the owner/operators of the new powerplant located in an extremely rural area of the islands.

These batch treat modules were particularly well adapted to this type of project in which ease of transport and installation were significant. Fiberglass non-corrosive construction was another asset for the powerplant as protection against the nearby corrosive salt air environment.

Shipment was made from Pennsylvania to the Philippines in June 1995 by means of 40' containers - this being the most convenient and efficient means of handling products on the receiving end from port to job site. In addition, engineers indicate the Cromaglass modular concept has a special advantage in designing the total wastewater treatment system. Another benefit of going modular on the powerplant project was the ability to place a "split" sewage treatment system - locating two (2) Cromaglass 15,000 gpd modules plus the adequate sludge processing tank at the powerplant offices and shop, built on a small island, with two (2) similar modules placed at the staff housing quarters nearby.

A unique aspect of this powerplant project is that the electric source to run the treatment system is immediately available "on spot." The power is 480 volts, 3 phase, 50 cycle for which a transformer was used with the Cromaglass control system.

To assure that the treatment system is placed into optimum working condition, a Cromaglass technical representative visits the project site for training in operation and maintenance. Although some of these projects are in isolated locations around the world this service has proven to be very valuable for the ultimate customer.
