Mechanical pretreatment eqipment

The main goal of mechanical pretreatment is removing of solid waste, sand, oil and grease from wastewater.

Grit separator — are desinged for cathing of waste like sand, glass, slags, etc.

Oil separators - of type CLARECO are designed for cathing and separation of oil substances(petroleum) coming from polluted wastewater.

Pollution sources:

–parking places, motor service stations

–petroleum station, warehouse iol products

–work houses, industry factories, etc.

Oil separators are devided into groups according the assembly, discharge, drainage area and effciency.

We offer the following separator range CLARECO:

Basic type: OS 2 - sedimentation chamber, coalescence filter, fibrooil filter – max. 4 mg/l;
Type with one adsorbent filter OS 2 SF – sedimentation chamber, coalescence filter, fibroil filter and sorbent filter – max. 0,5 mg/l;
Type with two sorbent filter OS 2 S2F – sedimentation chamber, coalescence filter, fibroil filter and two sorbent filter –max. 0,2 mg/l;
Type for big discharge : OS VP -5mg/l;
Type for big discharge and sorbent filter: OS VP -0.2 mg/l;

Division according to dranaige area:

Type Clareco Clareco	Dranaige area	Type Clareco Clareco	Dranaige area
OS 2	165 m²	OS 30	2490 m²
OS 4	380m²	OS 45	3900 m²
OS 6	510 m²	OS 65	5900 m²
OS 10	820 m²	OS 85	7900 m²
OS 15	1200 m²	OS 120	10 900 m²
OS 20	1650 m²	Bigger areas	Design according to the project

Technology description:

Oil separators are rectangular vessels contain several section zones. Wastewater inflows the sedimentation chamber through inlet pipe where the water suspended solids are settled uder gravitation forces. After this water comes into next section through coalescence filter and flows into separation zone. Here is a second coalescence filter and acumulative zone of separated products. Follows final treatment trought sorbent filter and treated water leaves separator trought outlet pipe.

Grease traps

Wastewater with higer content of greases from food industry, kitchens, restourants, etc. flows into grease traps befora biological teratment or discharge into sewege sysytem.

We offer wide range of rectangular, cylindrical and oval types for settling under or above ground, produced from polypropylene:

Type Clareco Clareco	Max inlet flowrate (l/s)	Number of dishes per day	Weight cylindrical type, (kg)	Weight rectangular type, (kg)	Weight oval type, (kg)
GT 2	2	to 200	90	200	200
GT 4	4	200-400	120	400	400
GT 6	6	400-600	150	600	600
GT 8	8	600-800	180	800	800
GT 10	10	800-1000	200	1000	1000

Cilindrical and rectangular types are designed for under ground settling as self-supported or with concrete around.
Oval type is designed for above ground settling over concrete base.
Description technology:

The waste water flows through an input pipe into the grease trap in which a cross barriers are assembled. This cross barriers helps to separate the rough pollutants from the water by sedimentation them on the bottom of the apart. The greases come to the surface of the liquid and after are being scraped out. Clean water leaves the installation through an output pipe.

Simply construction and easy operation Advantages:

- Simply construction and easy operation

- Above and under ground settling

- Wide range
