RECENT PROJECTS<br />

new contact cooling water treatment plant<br />

the decanters will be pumped to the<br />

sludge area and oil floating on the<br />

surface will be taken off by the top<br />

of the bridge scraper and removed<br />

by the oil skimmer. The decanted<br />

water will then pass to the ring filtration<br />

system.<br />

In the ring filters those particles that<br />

have a higher density than water<br />

and that have gotten through the<br />

previous process stages will be removed.<br />

Finally, the filtered water is<br />

pumped through the cooling towers<br />

then circulates back to cool the<br />

rolling mill equipment.<br />

Rebar made at the Gerdau<br />

Sayreville mill is typically sold in<br />

the northeast and Canada. The<br />

rebar runs the gamut from no. 3<br />

rebar, which is 3/8 of an inch in<br />

diameter, to number 18 rebar,<br />

which is about 2¼ inches in<br />

diameter.<br />
