General Statement on Water Quality Improvement for

LITTLE SUCKER & BIG SUCKER Wash Water Recycling System

The discharge quality of both The LITTLE SUCKER and BIG SUCKER water recovery systems will have a direct relationship to the water quality of the wash water effluent and proper maintenance performed.  Heavy emulsifying detergents, chemicals and lack of proper maintenance can cause the water quality to vary such that it may not meet acceptable levels in a given application or for discharge to sewer. 

The LITTLE SUCKER and BIG SUCKER wash water recovery systems typically incorporate over 12 water-cleaning technologies.  Each technology is incorporated in the system in a logical fashion to step by step improve water quality and reduce maintenance.  The maintenance required or specified in the Operations Manual is important in assuring consistent water quality.

Under normal operation, with proper maintenance, water quality cannot be guaranteed, but the system will:

Reduce oils and greases to below 15 PPM
Drop C.O.D.’s and B.O.D.’s typically over 75% to acceptable sewer discharge levels.  The ozonation option (standard on The BIG SUCKER) can greatly improve performance in this area.
Reduce suspended solids below 10 microns
Remove a high percentage of heavy metals. 
The Ozonation Option on The LITTLE SUCKER can greatly enhance its performance in this area.
Ozonation is a standard feature with The BIG SUCKER
Reduce odors caused by bacteria, sulfides and organics. 
The Ozonation Option on The LITTLE SUCKER can greatly enhance its performance in this area.
Ozonation is a standard feature with The BIG SUCKER
TDS levels are generally not reduced through filtration provided with the standard design packages of either The LITTLE SUCKER or BIG SUCKER.  TDS Levels may actually rise through the introduction of detergents or other cleaning chemicals but will tend to plateau-off due to the continuing loss of water during the washing process and the reintroduction of fresh make-up water.  Consult Western Water Products if TDS reduction or minimization is required in your application.

Intention of Filtration System Design:  The LITTLE SUCKER and The BIG SUCKER were designed to be a water recovery system to be used to recover the effluent from typical vehicle and /or parts washing and a host of other applications and clean it up for reuse as gray wash water.

Cleaning Technologies Incorporated into The LITTLE SUCKER and BIG SUCKER are:

·         Settling

·         Coalescing

·         Diffused Air Filtration

·         Aeration

·         Ozonation (Optional)

·         Recirculation

·         Adsorption

·         Absorption

·         Skimming

·         Pre-Screening & Straining

·         Multi-Cell Filtration

·         Purging

·         Floatation

 

Additional filters, which can be incorporated into these systems can be designed to eliminate or reduce the following:  Algae, Aluminum, Arsenic,  Bacteria,  Benzene,  Bicarbonate,  BOD,  Cadmium, Carbon Tetrachloride, Chloride, Chlorobenzene, Chloroethane, Chloroform, COD, Copper, Dichlorobenzene, Dichlorethylene, Dichloropropene, Dinitro-Phenol, Dinitro-Toluene, Ethylbenzene, Flourine, FOG (Fats, Oils, Grease), Gasoline, Hydrogen, Hydrogen Gas, Iron, Magnesium, Manganese, Methyl Chloride, Methyl Isobutyl Ketone, Naphthalene, Nitrobenzene, Nitrophenol,    Phenol,    Radon,    Suspended    Solids, Tetrahydofuran,     Tin,     Toluene,     Trichlorobenzene, Trichiorethylene, Urea, Xylene

The LITTLE SUCKER and BIG SUCKER water recovery systems are manufactured to provide the latest in filtering technologies available in the market today.  All water coming into the filtering system will be filtered and processed back to "Wash Quality Water" standards and additional filtration can be added to remove or reduce those contaminants mentioned above.   Detergent and other chemicals may not be entirely removed and additional filtering may be required, if removal is desired.   Water, which is intended to be overflowed or discharged to the sewer, can be cleaned to this quality prior to discharge to sewer.   Due to the varied nature of effluent water encountered and pumped into the systems and because the assurance and quality of routine maintenance cannot be guaranteed, a guarantee of a specific water quality is difficult to provide.

Although most wash pad designs have a discharge to sewer or septic field, these systems can also be operated as “closed-loop” wash water recycling systems with no discharge to sewer at all.  In this case, most regulatory agencies will not need to be concerned with the filtered discharge water contaminant limitations.  If the system is to be operated in this manner, we do recommend that the pits be pumped out once a year and the complete system “re-freshened” with fresh water.  If the application is especially oily or greasy as in the case of steam cleaning and degreasing engine parts, more frequent pit pumping may be required.
