Freytech oil water separators in car wash applications


Knowing that oil can get into the reclaim water, David F. Roberts, the President of Freytech Inc., recommends the use of an enhanced coalescing oil water separator. “Even trace amounts of oil in the recycled water can diminish the quality of the wash,” he said. “An ‘oil trap’ is not enough since it is simply a tank with baffled walls which does trap some of the oil floating on the surface of the water, but it will not trap all of the oil present below the surface.”

In addition, using such an antiquated method does not offer adequate protection against potential fines for discharging oil beyond the legal limits, according to Roberts. As for self serve carwashes, he said an oil water separator is strongly recommended since it is not uncommon to come across patrons changing their oil and dumping it into the carwash drain. He said that retrofitting existing tanks and installing a turnkey separator kit is a simple, affordable option that not only improves the wash quality and protects the environment but also offers peace of mind to the operator.

Freytech oil water separators in water reclaim systems


The self-service operator takes on special risks when recycling water because there is little control over what is put into carwash drains. Self-serve carwash patrons tend to dump many different types of pollutants into trenches, according to David Roberts, president of Freytech Inc. The most common substance put in the drain is used oil from an oil change. People will change their oil in a carwash bay when they feel that no one is looking, and this oil goes into the sewer or, even worse, into the reclaim system.


With the concern of used oil being dumped into drains, it is easy to see how an effective oil/water separator could be a good addition for a self-serve carwash. Especially considering carwash owners are solely liable if they surpass legal oil discharge limits in sewers. Roberts said discharging above these limits can result in "hefty monetary fines."

A Trace of Arsenic


For decades, officials have focused on trace arsenic in drinking water as the chemical’s primary public health threat; in 2001, the EPA dropped the limit for arsenic in water from 50 ppb to 10 ppb. But in the past few years, regulators have also begun to worry about exposure from foods and beverages. This summer, concerned about arsenic in pesticide residues found in imported juices, the FDA announced it will limit the amount of arsenic allowed in apple juice to 10 ppb, the same amount permitted in water.


Although the team’s initial tests found barely a trace of arsenic in baby formula and pureed baby food, later tests showed that two organic toddler formulas contained up to 60 ppb of arsenic (adjusted for dilution) — six times the EPA safety limit for water.

Labels on the formula canisters told why: They were sweetened with organic brown rice syrup, considered a healthy alternative to corn syrup. And while brown rice syrup is rare in baby foods, it is common in crackers, cereals, snack bars, energy bars and many products marketed as health foods.
