Elbi - AQUA Pura

Use

Treatment system for car washing equipment characterized

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

hydrocarbons and detergents, suitable for drain in the limits

of Tab. 4 Legislative Decree 152/06, Annex 5, final drainage

alternatively, reuse.

Operation

The wastewater from manual car washing is conveyed to the

sedimentation tank where all those substances that are heavier

than water are removed. In the same stage lighter substances like

oils, fats and foams are eliminated

The second stage consists of separating the oils and hydrocarbons,

by the inclusion of a coalescing filter, they undergo a further

reduction thus separating from the ef

fluent.

The third phase consists of an aerated percolating filter where

thanks to the presence of aerobic type biofilm the organic matter

(BOD and COD) and surfactants are removed.

The wastewater will be subsequently sent via equalization tank

with sand filter system (quartzite) and an activated carbon filter

where the wastewater will undergo further refinement.

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

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.

ENVIRONMENT SYSTEM

COMPLETE PLANT - DRAIN TO THE GROUND

Specification Item

A biological purification system for water coming from car washing

equipment drained into the ground.

The water treatment system from the car washes in question is

composed of:

1 sedimentation tank/grease trap 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

from the wastewater drained 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 filter” biological purification system

constructed with a corrugated container for greater underground

resistance and made of 100% recyclable polyethylene with rotational

moulding technology. The anaerobic percolating filter biological

treatment plants come complete with walkable inspection manhole

and are suitable for the insertion of extensions, compressor, non-

clogging tubular diffuser, random fill media in polypropylene with a

specific surface of 120m

, inlet and outlet system of wastewater

and relevant seals that guarantee a perfect tightness.

2 quartzite and activated carbon filters with a metal framework

(carbon steel) equipped with appropriate manhole, which allow

the replacement of filtering materials. The systems are powered by

equalizing tank (complete with submersible pump) made of 100%

recyclable polyethylene and complete with walkable inspection

manhole suitable for inserting extensions. The tank is equipped

with an inlet and outlet wastewater system and relative gaskets that

guarantee perfect tightness.
