1.01 Performance: The wash water recycling equipment shall be of the type manufactured by WaterCycle, Irvine, CA, Model ERC-Series and designed to handle the flow rate and water pressure required by the wash on a continuous basis. The wash water recovery system shall be the manufacturers "standard-duty" system for use in an exterior vehicle wash application. The system shall be suitable for use with either a drive-through or roll-over vehicle washes requiring nominal 40 micron or better water. The water recovery system shall also be capable of continuously processing water through the reclaim system for constant cleaning and ozonation/aeration of the water even when there is no demand for water by the wash. Unless there is a need for a Closed-Loop water recovery system requiring further filtering of "Rinse Quality" water through a Rinse Water Filtering module, the final rinse of the automatic wash shall remain on fresh water or "Spot-Free" water.

1.02 Water Collection: Water shall travel from a sand trap located on the wash pad to a series of clarifier pits. These pits should be size to allow free oil to float. Any free oil that floats can be removed by the use of floating oil pillows in the pits or through suction during occasional cleaning of the pits.

1.02.01 OPTIONAL Independent Sludge Removal Pump: The independent sludge removal pump shall be controlled by a separate timing control which is timed to come on periodically to remove sludge from the pit and place it into an above ground mud/oil hopper for easy disposal. The pump shall be at least 1/3 HP in size and shall be an effluent pump capable of pumping objects up to 3/4" in size.

1.02.02 Sludge Pump Control: The independent sludge removal pump shall be controlled by a separate timing control which is timed to come on periodically to remove sludge from the pit and place it into an above ground mud/oil hopper for easy disposal.

1.02.03 Pit to Filtration System Transfer Pump: A separate water transfer pump shall be located in the pit to provide water to an above ground filtration console. The transfer pump shall be adequately sized to keep up with the water flow required by the automatic wash and shall be housed within a 650 micron filtering barrel which is designed to filter out debris and thereby avoid plugging the pump and other filters downstream from the pump in the filtration system. The purpose of this pump is to positively feed water to the water recovery system to avoid loosing prime in the line commonly associated with foot valves and suction pumps. Therefore, a foot valve and suction pump shall not be allowed.

1.03 Transfer Pump Control: The water transfer pump shall be operated by a separate float switch and shall pump water to the water recovery system console for continuous filtering and odor control by an automatic Ozonation process. Ozonated water shall be returned to the pit when there is no demand for water to the wash process through plumbing return line back to the pit to keep pit water rotating and to avoid stagnation.

1.04 Filtration System Solids Removal: When required by the wash equipment, water shall be directed to the wash by the output pump of the water recovery system. Prior to being diverted to the wash, water shall first be fed through a Cyclone Separator designed to eliminate heavy dirt from the water. The number of Cyclone Separators shall be sufficient to filter the required water flow rate demanded by the wash equipment. The cyclone pump shall produce enough pressure to accommodate the pressure drop across the Cyclone separator and still provide at least 40 PSI of water pressure to the wash equipment. Filtration techniques of settling, screening, ozonation/aeration and cyclone separation shall provide water quality at 40 micron or better. The Cyclone Separator shall capable of being cleaned by opening a discharge valve to remove collected dirt from the filtering device. The discharge valve shall be automated with an electro-mechanical actuator and timing control to purge built-up dirt in the line on a daily basis.

1.05 Filtering and Pumping Console: The console shall contain all pumps, floats, pressure switches, automatic purge valves, Ozonation/Aeration device, electrical panel, etc., so that no interconnecting wiring will be necessary between the console and the tanks. An output pump shall be supplied and mounted inside the console to provide reclaimed wash water to the wash on demand. This pump shall receive its signal to pump water to the wash equipment from the wash electrical control system. The console shall be completely enclosed to provide maximum shielding of internal components from the weather and shall be provided with access panels all around providing easy access for servicing.

1.06 Electrical Control Panel: The system console electrical panel shall come equipped an electrical control panel capable of controlling all of the functions of the water recovery system.

1.07 Continuous Water Recirculation: The system shall employ a method of continuous water Recirculation for the constant aeration of water throughout the system which will aid in the prevention and buildup of bacteria, virus, algae, etc. and also to inhibit the buildup of foul odors without the use of additional chemicals. Ozonated water shall be returned to the pits through the tank overflow line to enable treating of pit water as well as tank water on a continuous basis to control odor.

1.08 Disinfectant System: The primary disinfectant control system employed shall be an automatic ozone injection control system and shall be connected to the pretreatment tank.

1.09 Instruction Manuals: The system shall come with an instruction manual complete with a description of operation of the system as well as all major components and with a complete parts list showing manufacturer's names and parts numbers of all major buyout components.
