Self Cleaning Filters Eliminate Particles
OMC Spruce Pine, Spruce Pine, N.C., is a “lost foam” casting facility for the manufacture of marine engine parts. A styrofoam mold is created in the shape of the desired part and then surrounded with sand. When molten aluminum is poured onto the mold, the metal takes the shape of the part and the foam is burned off.

Filtering Metallics at Midland
Producing steel that's consistently clean inside and out—free of inclusions and surface blemishes, that is—from heat to heat is a daunting task. J&L Specialty Products' mill at Midland, Pa., is ensuring high quality and cutting downtime by an improvement of the cooling-water system serving its continuous slab caster.

Automatic Water Filter Keeps Drippers Dripping
The Blasi Family has been supplying grapes for the production of Chadeneur and Zenfidale wines since the mid 1950s from their farm in Santa Rosa, Ca. Second generation cultivators Bob and Gary run the 109-acre farm, of which 75 acres are grapes. The farm has a well that dispenses the 200 gpm used for the irrigation system. The Blasis converted the system from sprinkler to drip, a change that required much cleaner water.
Filtration System Expenditure Results in Payback Measured in Days
This manufacturer of household light bulbs experienced a real savings of $120,000 per year on a capital investment of $11,000 resulting in full payback in just 33 days.
Bodacious Solution At Bodega Harbour

Process Cooling of Engine/Generator Sets with Reuse Water
One of several municipal waste water treatment plants (WWTP) in St. Louis is located along the banks of one of the largest tributaries to the Mississippi River. This 100 MGD (million gallons per day) facility has a large demand for service water with low suspended solids.

On-Site Wastewater Reuse
Located along the banks of one of the largest tributaries to the Mississippi River, this 100 MGD (million gallons per day) wastewater treatment plant has a large demand for service water with low suspended solids. Nearly 3 MGD of water are needed for cleaning devices on the bar screens, spray water to keep the belt presses clean and porous, pump seal water, service water at hose bibs and equipment wash stations and water to cool several large engine/generator sets that run off of methane gas produced from sludge digestion.

A Treatise on Turbidity and TSS
When two distinct physical parameters are used interchangeably, an intimate understanding of both is in order to know when this is justifiable. Two such parameters are turbidity and total suspended solids. In many industries today the concentration of total suspended solids is of utmost importance to quality control and process optimization. However, the measurement most often employed is turbidity.

Twenty Years of Cooling Water Treatment Experience in Manhattan
The air quality in The Big Apple can result in some pretty substantial problems with rooftop cooling towers for commercial HVAC systems. Twenty years ago the owners of a large uptown commercial building on Madison Avenue, NYC decided to include an automatic self-cleaning screen filter in their new HVAC system to ward off likely problems with water quality. Today, the big roof-mounted 900 ton cooling tower continues to acts as a large community air cleaner.

Amazing Clarity for Agricultural Water
Northern Sunrise County is a picturesque Municipal District in Northern Alberta offering over 21,500 square kilometers (8300 square miles) of adventure and exploration in a pristine landscape. Located 485 kilometers (300 miles) north of Edmonton, Northern Sunrise County is a short drive south of Peace River. Farmer’s markets, museums, hunting, fishing, golfing, camping, early Native American re-enactments, the Harmon Valley Rodeo, many parks and a winter carnival make this a year-round vacation spot.

Four Seasons but Always Green
It is estimated that 30-36 million Americans play golf. That’s nearly half of all golfers in the world. And many of those golfers play at TPC Four Seasons Resort and Club Dallas at Las Colinas located in Irving, Texas. See Figure 1 for one of the many fantastic views of the area. The resort covers 400 acres of rolling North Texas hills located just minutes from downtown Dallas. Four Seasons not only sports a challenging par 70 18-hole course designed by Jay Morrish but is also home to the Byron Nelson Golf School. And who hasn’t heard of the Byron Nelson Championship, a PGA Tour event that is held annually at Four Seasons.

Full-Stream Cooling Tower Filtration
Water chemistry is routinely addressed in cooling systems. Scale formation, corrosion and biological growth are just some of the activities that can be abated by proper use of chemical additives. Foreign matter in the form of suspended solids though, is too often overlooked in the design stage. Control of this physical problem is generally addressed sometime after operation has begun when heat transfer problems arise.

Lush Landscape in the Desert, A Testimonial
Larry lives in a semi-desert region of Idaho where summer daytime temperatures often exceed 100°F and rainfall amounts to a scant 10 inches per year. The meager natural vegetation consists of cacti and small patches of pale grasses and scrub. Much of the land is rocky and barren. Having colorful landscape around his retirement home is not easy. Let’s let Larry tell his own story:

Manufacturing Facility Chooses Automatic Self Cleaning Filter for Efficient and Effective Chiller Protection
Cooling towers dissipate both ambient and process heat in most large manufacturing facilities. These structures facilitate the transfer of unwanted energy (heat) from a transport liquid (usually water) to the atmosphere. Problems with efficient heat transfer, equipment protection and pathological risks to employees can most often be traced back to an issue with suspended solids. These solids can originate in the process, in the piping, from the atmosphere or from internal biological growth.

Protecting Artifacts at The Jewish Museum
Thousands upon thousands of people visit 1109 Fifth Avenue in Manhattan each year. This is the location of The Jewish Museum, one of the largest of its kind in the world. For over 100 years this museum has displayed past and present Jewish culture, both secular and religious, to the world. Special care must be taken in protecting over 26,000 paintings, sculptures, works on paper, photographs, ethnographic material, archaeological artifacts, numismatics, ceremonial objects and broadcast media materials. This care begins with proper environmental conditions that rely on a dependable HVAC system.
