Septage Receiving Station in wastewater treatment
Septage Receiving Station Unit STV/C
SEPTAGE RECEIVING STATION
design and manufacturing ability of SEFT with the realization of product that can be customized in all parts to be satisfaction each customer request.
STV/C is a unit compact able to carry out the pre-treatment of screening of wastewater from industrial processes of various types. Before they are released in wastewater treatment plants.
The entrance is equipped with a quick attack (Perrot type) and an electromechanical valve.
The wastewater discharged directly from the tanker, is filtered by a screw screen that removes the solids that are then drained and compacted and then discharged into a bin or bagged.
Functions of Septage Receiving Station:
– Screen – Filtration
– Fecal sludge treatment
– Sludge dehydration / compaction of the solid removed
Advantages of Septage Receiving Station:
– Equipment Customized
– No odor
– No pumps
– No obstructions
– Low operating costs and maintenance
– Compact equipment
– Construction work is not necessary
– Low residual content of organic matter
– Reduction up to 40% volume of the solid removed
Pre-treatment Combined Compact Unit STV/T
This combined machine is fed by a pump or to gravity, through a fixed pipe, the effluent passes through a screw screen that removes the most large solid particles, then goes to a sedimentation tank where the particles sedimented are then removed by a system of scews.
As an option you can install the system for removal of fats and suspended oils.
Features:
– Filtration / Screening
– Wash / compaction of solids removed
– Extraction of sand
– Degreasing (on GDF/D version)
Advantages:
– No odor
– No mechanical parts in contact with the sewage
– Low erection and maintenance costs
– No hanging bears
– Possibility of sand washing before discharging
– Completely close machine
– Low operating costs and maintenance
– Reduced space requested
– Construction work is not necessary
– Ease of installation and management
– Low organic matter in the solid residue extracted
– Reduction up to 40% in volume of solids removed
Pretreatment plants
Combined Pretreatment Compact Unit GDF/D Design and manufacturing
This Combined Pretreatment Compact Unit equipment is fed by a pump or to gravity, through a fixed pipe. The effluent passes through a screw screen that removes the most large solid particles, then goes to a sedimentation tank where the particles sedimented are then removed by a system of scews. As an option you can install the system for removal of fats and suspended oils.
Features Combined Pretreatment Compact Unit:
– Filtration – Screens
– Wash and compaction of solids removed
– Extraction of sand – grit
– Degreasing (on GDF/D version)
Advantages Combined Pretreatment Compact Unit:
– No odor
– Low operating costs and maintenance
– Reduced space requested
– Building work is not necessary
– Ease of installation and management
– Low organic matter in the solid residue extracted
– Reduction up to 40% in volume of solids removed
Compact Unit Pretreatment Plants VSD Design and manufacturing
Combined equipment able to perform two functions simultaneously:
– Grit – sand whasing process
– Grit – sand removal process
– Oil and degreasing removal
The effluent is fed to the machine through a fixed pipe and decants in the tub, the sands are then removed by a system of augers, while fats and oils surface are removed from the system of deoiling by an air blowing.
Combined Wastewater pre-treatment Unit GDE/D Design and manufacturing
PRE-TREATMENT COMBINED UNIT: SEFT MANUFACTURING EQUIPMENTS FOR SCREENING, DEGRITTING AND MANUAL REMOVING OF OILS AND FATS
The GDE/D model performs: screening, sand removal, fat and grease manual removing.
GDE o GDE/D could be supplied in 2 models:
1 – Grit removal + Screw screen with perforated sheet or wedge wire.
2 – Sand classifier + Rotary drum filter wedge wire profile.
Based on the chosen model, pre-treatment combined unit, you can get it will be possible to get a different type of screening, the sewage goes through the screening section for the solid parts removal, then the sewage falls down a decantation tank where the particles go down, here an extraction spiral screen removes them.
Advantages of Combined Wastewater treatment Unit:
– Odor free
– No clogging
– Low maintenance and operation costs
– Low room needed
– No construction works needed
– Easy to install and operate
– Low residual organic content in the washed out solid
– Volume reduction (up to 40%) of the washed out solid
– Sand removal: >=90% of particles up to 200 μ
