The oil separators are the most suitable method for cleaning waste water containing residues of oil and diesel. Their installation ensures complete protection.

Oil separators are divided into the ones of:
  • Domestic use
  • Professional use (gas-car-washing machines)
  • Professional use- on a large-area (parking)

Types of oil separators:

    • Oil Separators BOX

Imhoff Septic Tanks are single-paneled. Their internal configuration is characterized by two communicating compartments. Imhoff Septic Tanks have cleansing and purifying properties and therefore the processed  water output can be provided for underground irrigation or plant cleansing.

Imhoff Septic Tanks are used for the following purposes:
  • General household applications
  • Toilets of: sports facilities, industrial buildings, restaurants and hotels, schools, offices, etc.

The selection of the tank is based on the number of the Equivalent Population (IP) it serves.
However, choosing a larger volume tank does not reduce its performance. On the contrary, it reduces maintenance costs since its discharge is made less frequently.

  • Typical IMHOFF tank
  • MAXI tanks. Tanks of the MAXI class are available for large facilities.
  • COMPACT tanks. To install tanks in small gardens or patios or to place them in narrow ditches and in general, in situations where space is limited as well, such as when the tanks have to pass through the interior of the house, through narrow aisles or doors, COMPACT models of reduced width are available.
  • CARRABILE Tanks. For the placement of tanks under car passageways or in parking areas, the IMHOFF Heavy Type models, under the trade name CARRABILE are available. These ones withstand deformations that may occur due to loads <125KN which correspond to the passage of the car.

    • DISTRIBUTION CONTAINERS. They are spherical and irregularly shaped containers with excellent resistance to ground pressures when empty and they have an internal diameter of more than 100 cm. The lower part is perforated while the top is solid.

The two-septal septic tank system consists of two pipe-attached tanks and three pipe-attached tanks for the three-compartment ones. The diameter of the connecting pipe is at least 10 cm.

They are only used for the primary treatment of household wastewater, since they only have cleaning and clarification properties. Therefore, the processed water is either discharged underground (in dispersion tanks, pre-existing absorbent pits, underground irrigation), or to systems of secondary treatment or plant cleansing.

However, the Compact tanks are of reduced width and are used for installment in small gardens or atriums or narrow ditches and generally in situations where space is limited, as well as in cases where tanks have to pass through the interior of the house, narrow aisles or doors etc.

The tanks of the Blok series consist of a single tank which is divided into two or three (for Three-chamber) compartments. As about all the rest ones, what has been described above for common septic-eds is also applicable to them.

Reactors in this case are available in two categories, the STAR separate tank systems and the BLOK single tank systems.

Active sludge reactors are suitable for the treatment of domestic, or identical, wastewater.

Biological filter reactors are available in two categories.

The STAR class where the treatment is made in two different tanks and the BLOK class with a single compartment.

The reactors of both categories process domestic waste to such an extent that it can then be disposed of in surface water recipients.

BLOCK type

Tanks of this type are single tanks consisting of a solid separation compartment and a biological filter compartment.
Ideal for the treatment of any type of waste coming from small houses or similar facilities, even if the waste comes from occasional uses, with the prospect of being disposed of in large surface water recipients.
Prior to the biofilter tank, a grease trap has to be installed.

STAR category

These reactors are ideal for the treatment of all types of waste from small dwellings or similar facilities, even if the waste comes from occasional uses, with the prospect of being disposed of in large surface water recipients.

Prior to the biofilter tank, a grease separator and IMHOFF septic tank should be installed. Star reactors are available in the following categories, EcoStar, AirStar and PowerStar.

 

Biological filters for the treatment of domestic sewage, for its surface disposal, are divided into two categories: Acquapower and acquaperformance.

The Acquapower category consists of biological filter reactors, upstream of which there must be a primary treatment system consisting of a separator and an IMHOFF type tank.

The acqueperformance consists of single-bed biofilter tanks upstream of which a grease collector has to be placed, through which the pollutants must pass. Internally, these tanks consist of a solid separation compartment, followed by the biological filter compartment, with the dimensions that would enable the sewage to remain for oxidation therein for about 36 hours.

Reactors of both categories require power supply for their operation and are suitable for processing domestic or identical sewage with any supply even for occasional uses.

A tank is used to divert stormwater.

The system is divided into three parts: overflow, storage and recovery (underwater pump controlled by a timer) and oil separator.

CAR-WASH

Sewage treatment plant facilities are designed to ensure the disposal of sewage CWF into surface water CWI or in the ground or its reusal CWS. The CWF treatment plant consists of: sediment and oil separator. The CWI Biological Cleaning Unit has the following: sediment, oil separator, oxidation, anthracite filter. The CWS sewage treatment plant consists of: sediments, oil separation, organic oxidation tank, sand (or sand / anthracite) / GAC)  filtration, and final filter.

DRY-WASH

The system includes a first homogenization and equalization section with a constant power supply for oxidation after external filtration with the use of an automatic self-cleaning filter. The Dry-Wash treatment plant is suitable for clean soapy water found in household washing machines, in washing machines, in industrial laundries, in dry-cleaners for hotels, residences, restaurants.

WINE-WASH

The WineWash treatment plant is best suitable for the cleanliness of water coming from winery, grapes and wine.

Categories:

Balancing Tanks. The balancing tank is recommended for all activities (public places, camps, businesses, etc.).

Denitrizers-Pro denitrizers. Post Denitrizers -Denitrification is used to reduce the level of nitrogenous compounds (nitrates and nitrites) in liquid waste. De-nitrification can occur before the oxidation part (pre-denitrification) and after the pre-existing purification unit (post-denitrification). The sewage treatment plant with denitrification systems is suitable for their disposal in areas with parks and lakes.

Sand-quartz filter. The sand-quartz filter is a filtration system suitable for reducing floating particulates in liquid waste. It can be used to refine water from groundwater, from wells, from rainwater. It can also be used as a third degree treatment to further reduce the floating solid particles.

Filter of Sand – Anthracite. The sand-anthracite filter is used for filtering water from floating solids and partial adsorption of many pollutants, making it particularly suitable for the treatment of groundwater and of deep wells water. This filter may also be used for the purification of liquid waste coming from the facility treatment for agricultural use.

Active Carbon Filter. The high capacity of activated carbon in pellets, the adsorption of organic and inorganic compounds, makes such equipment suitable for the removal of gaseous and liquid pollutants from sewage (eg VOCs, chlorine, pesticides, dioxins, asbestos, minerals, etc.) . For effective and efficient removal of the compounds, it is necessary to separate the oils and fats with the appropriate systems (liposuctors, oil separators). The GAC filter is the best adsorption filtration system for water treatment.

Filter Anthracite – simple and heavy type. Appropriate filtration system for the reduction of floating particles in sewage treatment plants. For the removal of these compounds it is necessary to separate the oils and fats with the appropriate systems (liposuits, oil separators).

Chlorination shafts. Disinfection is achieved by contacting the waste water with a tablet of specific salts (chlorine tablets or liquid chlorine may also be used). The contact time between the disinfectant and the wastewater is about 20 minutes. Chlorination shafts can be divided into two categories:

– Static disinfection

– Pump disinfection

Categories:

  • Heavy-duty polyethylene shaft (for vehicles)
  • Pisa shaft
  • Milano shaft
  • Sampling shaft
