ProTech Completes Successful Demonstration of Polymer Coagulation System for Stormwater Treatment
Systems from ProTech are currently operating at several large-scale construction sites
NAPA, CA (PRWEB) April 26, 2004 -– ProTech General Contracting Services Inc.
(ProTech), a water treatment company specializing in stormwater control, today
announced that it has successfully demonstrated its polymer
coagulation/flocculation system for runoff and stormwater clarification at
several large-scale project sites. The polymer coagulation/flocculation units
were a key component in the stormwater treatment systems employed at several
construction sites in California’s Central Valley, including sites of several
thousand acres requiring multiple 1000 gallon per minute
systems.
“Construction site runoff and stormwater is increasingly subject
to stricter discharge water quality standards,” says Len Pisciotta, President of
ProTech. “Today the only practical way for many projects to meet permit
requirements is by using an active technology to improve sediment removal
efficiency and, consequently, water quality. ProTech’s water clarification
systems incorporate a coagulation process that vastly improves sediment removal
efficiency. The results are higher flow rates, smaller holding basin volumes,
and improved water quality – all at lower cost.”
Many construction
projects, particularly those where runoff contains fine-grained sediment that is
impractical to remove by simple gravity sedimentation or filtration, are finding
that the only way to meet permit requirements is to incorporate some type of
active treatment process in their water management system. Polymer-based
coagulation systems are among the most efficient and cost-effective methods
available. Although polymer clarification has been used for many years for
industrial and other applications, it has only recently been used in the mobile,
temporary treatment systems required at construction sites. ProTech’s water
treatment systems are designed to meet site-specific flow requirements and
discharge permit criteria, and typically include clarifier tanks, sand filters,
bag or cartridge filters, as well as the polymer coagulation system. Systems are
also equipped with automated turbidity meters with chart recorders, overflow
sensors, automatic flow control switches, or pressure sensors linked to cellular
devices for remote monitoring and operation. During the rainy season of winter
2003/2004, ProTech installed and operated several stormwater clarification
systems utilizing polymer coagulation/flocculation.
As an example, at
the Lincoln Crossing 1000-acre planned community in California’s Central Valley,
ProTech installed and operated a 1000 gallon per minute system to treat runoff
that contained high levels of fine-grained, colloidal material and iron oxides.
Runoff at the project was often very turbid, with measured turbidities commonly
over 1,000 NTU (Nephelometric Turbidity Units). Discharge from the site led to
surface waters that support steelhead trout, which are listed as threatened
species under the Endangered Species Act. Consequently, maintaining water
quality was a high priority at the project. Because the colloidal material did
not settle and was difficult to remove, a ProTech polymer
coagulation/flocculation was incorporated in the water treatment system
design.
“To meet our discharge permit requirements, we needed a temporary
water treatment system to treat site runoff,” says Ed Horn, Construction
Manager, SunCal Companies. “We looked at several alternatives, and found that
ProTech’s water treatment system met our water quality criteria. ProTech
incorporates the latest filtration technology, and meets Best Management
Practices and Best Available Technologies standards of the California Regional
Water Quality Control Board. Several storms occurred during the winter rainy
season, including one with two inches of rain in six hours. The treatment system
operated flawlessly. Discharge never exceeded 50 NTU, although influent was over
1,000 NTU.”
ProTech offers water treatment systems for a variety of
applications, including construction site and stormwater runoff, dewatering
operations, and well drilling, as well as many other projects. The Company also
provides design and engineering services, planning and permit application, water
treatment system installation and maintenance, and monitoring and compliance
documentation. Based in the San Francisco Bay Area, ProTech services projects
throughout the West.
ProTech will be exhibiting at StormCon, the third
annual North American Surface Water Quality Conference and Exposition, on July
27-29, 2004 in booth #116, Desert Springs Marriott, Palm Desert, California.
Chris Ott, ProTech’s Chief Technology Officer and Rebecca Mirsky, Ph.D., P.E.,
and ProTech Senior Environmental Engineer, will be presenting a paper entitled,
“Polymer Coagulants and Flocculants to Improve Clarification Efficiency in
Construction Site Stormwater” on July 28 at 2 p.m. (Session Number B50). To
