Wastewater Recirculated to the Chiller Or Tower Loop

Before governments began policing wastewater discharges and long before it was popular to be " green " in your process, a Swedish company named Wirsbo partnered with a Minnesota based water treatment company to solve both a process wastewater problem and establish a system to save the process water.

Wirsbo, founded in 1694 in Sweden is most famous for its world leading in floor radiant heat tubing.

Wirsbo manufactures its tubing down a robotic extrusion process, cooling the tubing in water troughs fed 24 / 7 by the robots. Because of the sky-scraping temperature, and the unfastened air trough, the cooling water in the trough was black and oily, with a resplendent odor. The trough itself had consequence algae 1 - 2 " thick on the sides. Minnesota Water Treatment arrived with ionization and oxygenation technology in 1996 to design and develop a chemical free system.

Wirsbo has a 50 year warranty on their tubing, the use of chlorine or incommensurable chemicals degrade the life of their product. Tests after cooling, in chemically treated water were employed and were the same. Chemicals were not an option!

Minnesota Water Treatment not unrivaled solved the " black water " cooling trough question, a recirculation game plan was ultimately developed allowing water to recirculate through 60 ton EVAPCO cooling towers and chiller bundles in later years.

" In addition to the utmost black water on domiciliate, it was determined that fusaria and nematode infestations to the cooling trough water existed owing to loading dock doors allowed these common spores to subsume the unbarred trough water on each robotic process line. "

Wirsbo implemented programmable controllers and an ionization test on every shift to prevent recurrence of the microbes.

Glass media was implemented in 2006 at flight rates of 60 GPM to 400 GPM to fresh lower microns of filtration and maintenance cost. Filtration has evolved from response to DE, DE to Zeolite, Zeolite to Glass over the 13 interval site history, with Glass media extending both media life and reducing fruit by 50 %. The glass media is used in Pentair TA 60, TA 100 and TR 140 low nuisance, high flow proportion sand filters with high flow rate valves. Two years strayed re - bedding is now historical.

The use of ASAHI unrelated pressure valves has allowed a headered bank of filters to automatically shift filters for backwashing at the convenience of on - hangout personnel. Previous dash filter systems did not allow the recirculation and rinse of the water and would shut down flow in the troughs requiring cleaning or change out to continue manufacturing tubing.
