subject: Eliminate Bag Or Cartridge Maintenance In Car Wash Reclamation Systems [print this page] Municipal regulation of new car wash construction requiring reclamation systems has created specific challenges in water treatment with most sites experiencing noxious odors and algae growth on the walls due to the reclamation water.
ECOsmarte oxygenation/ionization systems have been installed since 1999 in Michigan, Maine and Minnesota with specific success utilizing the existing water treatment equipment onsite. Installation time for the average six bay wash has been accomplished in less than 2 hours. The DC voltage controller, self sacrificing copper anodes and titanium/platinum oxygenation anodes operate at a cost of about $50 per bay, per year with 30 minutes of quarterly maintenance.
Previous systems have required weekly cleaning or replacement of bag or cartridge filters and have been largely ineffective on odor issues in the winter months particularly. A glass media wastewater filter is installed in place of the cartridges and requires a 5 minute simple backwash once per month. The glass media filter has no operating cost and is in expensed initially.
In 2009, the addition of low pressure, high flow rate glass media filtration has been engineered to better separate solids using the glass and oxygen in a swimming pool sand filter platform. On each site the algae build-up on the walls stopped (in both summer and winter) and the odor has been virtually eliminated. The algae itself is often a source of the odor but the reclamation sump is the ultimate culprit with soaps, minerals, dirt and plant spores creating an optimal environment.
Source water dissolved oxygen (DO) levels are increased from 2 to 3ppm to 6.0 to 6.5 range ppm and a low level copper ionization level of .2 to .4ppm is maintained through both programmable and flow switch controllers. The increases in DO are true in both hot and cold water, and regardless of ph.
Maintenance personnel maintain the copper residual with a simple Lamotte EC 70 test kit, a 5 drop reagent and quarterly cleaning of the anodes in a diluted acid wash.
The reclamation system can be installed as part of a new car wash build or added to all existing water treatment strategies.
