CAR WASHES

COMPLETE PLANT

Use

A treatment system for car washing equipment characterized

by the presence of pollutants such as suspended solids, oils,

hydrocarbons and detergents, suitable for drain into public

sewers.

Operation

The wastewater from manual car washing is

first conveyed to the

sedimentation tank where sedimentable materials are withheld,

and are then sent to the oil separation section where the oils and

hydrocarbons are withheld. Finally, it is conveyed to the air blown

percolating filter where the biological treatment takes place.

Maintenance

Sedimentation tank/grease trap maintenance

You are advised to check every two months the amount of sludge

in the sedimentation tank/grease trap and if necessary remove it.

Grease separator maintenance

Every two months check the volume of separated oils and

hydrocarbons and remove them at least every six months.

Remove and clean the coalescing filter at least every six months.

Maintenance of the air blown percolating

filter

Regularly check that no anomalies have occurred to the electrical

panel if present.

Verify that the blower works properly, that is, movement must be

observed in the volume of oxidation coinciding with the operating

time.

Every six months carry out the removal of excess sludge. Such

removal must be carried out by a specialized company.

Specification Item

A biological purification system for water coming from car washing

equipment drained into public sewers.

The water treatment system from the car washes in question is

composed of:

•

1 sedimentation tank/grease trap for sludge constructed with

a corrugated container for greater underground resistance and

made of 100% recyclable polyethylene with rotational moulding

technology. The sand traps are complete with walkable

inspection manhole and suitable for the insertion of extensions,

inlet and outlet system of wastewater and relative gaskets that

guarantee perfect tightness;

•

1 grease separator/sand trap with coalescing filter suitable to

separate by gravity the non-emulsified oil/hydrocarbons lighter

than 0.85 g/cm

3

from the wastewater drain through static

separation and coalescing filtration with efficiency increased

by 95%. The grease separators/sand traps are constructed

with a corrugated container for underground resistance and

complete with walkable ribbed maintenance lid both made

of 100% recyclable polyethylene with rotational moulding

technology.

•

The grease separators/sand traps are complete with walkable

inspection manhole and suitable for the insertion of extensions,

a coalescing filter with its stainless steel grid filter which is easily

removable for cleaning operations, inlet and outlet system of

wastewater and related seal, which ensure the perfect tightness;

•

1“air blown percolator”biological purification system constructed

with a corrugated container for greater underground resistance

and made of 100% recyclable polyethylene with rotational

moulding technology. The aerobic percolating filter biological

treatment plants come complete with walkable inspection

manhole and are suitable for the insertion of extensions,

compressor, non-clogging tubular diffuser, perforated input pipe

to ensure a distributed percolation across the entire surface

of the filter, random fill media in polypropylene with a specific

surface of 120 m
