Fat and Oil Separators

Materials from which our fat and oil separators are made:

• Environmentally tested (do not pollute the environment) made of HDPE,
• Have inlet and outlet diameters to which connection is easily made,
• Cheaper than any other type of separators,
• Guarantee waterproofing and a long-term solution, as the material only loses 5% of its properties after 50 years of use,
• Resistant to UV rays, withstand extreme temperatures from -30° C to + 80° C, and have good load-bearing capacity,
• Resistant to impacts, meaning no visible marks remain, and moving them won’t cause damage,
• And importantly, they are easy to install and have minimal maintenance costs.

Čabar Plast separators are key elements in the wastewater purification process, especially when it comes to separating light liquids like oils and fats from other wastewater components. These separators can be categorized based on the method of installation and the type of purification process they use.

Technological processes within separators:

1. Sedimentation Process

The sedimentation process forms the basis of the separator’s operation, where gravity is used to separate heavier particles, which have a greater mass than water, allowing them to settle at the bottom of the separator. This process is effective for separating coarse pollution fractions such as sand, silt, and other particles.

2. Free Oil Flotation Process

In the flotation process, free oils and fats that are lighter than water are separated to the surface of the liquid thanks to their lower density. The efficiency of this process is significantly increased by using a coalescing separator, which allows small oil droplets to merge into larger ones and more easily separate from the liquid.

3. Sorption Purification Process

An additional stage in the purification process involves filtration through a sorption material, which can absorb remaining pollutants from the liquid. This process allows for further cleaning and improvement of the purified water’s quality. The filter material can be regenerated or replaced, depending on the degree of saturation and pollution.

For optimal functioning and efficiency, regular maintenance of the separators is very important, including checking the condition of the coalescing filter, cleaning the sediment, and regenerating or replacing the sorption material. With proper design, installation, and maintenance, Čabar Plast separators can significantly contribute to environmental protection and efficient wastewater management.

Fat Separators

Fat separators are key elements in wastewater treatment systems, especially in facilities where food is processed and where large quantities of oils and fats are used. They are designed to efficiently separate fats and oils from other components of wastewater, thereby reducing the risk of clogging and damage to sewage systems.

Capacity and Design of Fat Separators

The capacity of fat separators should match the quantity and type of wastewater generated at a specific facility. This means that the size and design of the separators must be adapted to the specific needs of restaurants, hotels, the food industry, slaughterhouses, and similar establishments. The efficiency of separators directly depends on their ability to handle the maximum flow and concentration of fats in the wastewater.

Separation Process in Fat Separators

The separation process in fat separators encompasses several key steps. First, wastewater enters the separator where coarser particles settle at the bottom. Then, the water passes through a series of partitions or filters that further separate fats from the water. Fats, due to their lower density compared to water, float on the surface where they are retained until removed.

Maintenance of Fat Separators

Regular maintenance is crucial for maintaining the efficiency of fat separators. This includes visual inspection, cleaning accumulated fats and oils, and controlling the filters and partitions within the separator. Removed fats and oils should be disposed of in accordance with local waste regulations to avoid environmental pollution.

Installation of Fat Separators

When installing fat separators, it is important to ensure the proper location and distance from the source of wastewater. The optimal location allows for the reduction of wastewater temperature before entering the separator, which can improve separation efficiency. Also, easy access to the separator for maintenance and inspection should be ensured.

Fat separators are essential for effective wastewater management in facilities that intensively use oils and fats. With proper design, installation, and maintenance, these systems can significantly contribute to the protection of sewage infrastructure and the environment from the negative impacts of contaminated wastewater.

Oil Separators

Oil separators are essential devices for wastewater treatment in industrial and commercial facilities where oils and petroleum derivatives are used. These separators are designed to efficiently remove oil and other light liquids from wastewater before it is discharged into the sewage system or the environment. There are three main types of oil separators: gravity separators, coalescent filter separators, and bypass separators.

Gravity Separators

Gravity separators use the principle of density difference between oil and water. Oil, being lighter than water, naturally rises to the surface where it can be easily removed. These separators are usually equipped with a skimmer that continuously removes the oil layer from the surface.

Coalescent Filter Separators

Coalescent filter separators use special filters that increase the process of joining small oil droplets into larger ones, making it easier for them to be separated from the water. Coalescent filters are particularly effective in removing very fine oil droplets that cannot be easily separated by gravity methods.

Bypass Separators

Bypass separators are designed for situations where large volumes of water need to be treated in a short period of time, such as during heavy rains. These separators allow a portion of the water, which exceeds the capacity of the separator, to be diverted (bypassed) directly into the drain, while the contaminated water with oil continues to be treated in the separator..

Biological Sponge Separators

Biological sponge separators are used for purifying wastewater using biological processes. These separators use specially designed sponges or media that serve as a home for microorganisms. Microorganisms naturally found in wastewater, when settled on the sponge, form a biological film that effectively degrades organic materials and pollutants present in the water.

Purification Process:

• Arrival of Wastewater -Wastewater enters the separator where initially larger waste and particles are separated using mesh filters or grates.
• Sedimentation -Heavier particles settle at the bottom of the separator, while lighter pollutants such as oils and fats rise to the surface and are removed.
• Biological Treatment -Purified water from previous steps passes over or through biological sponges. Sponges are porous structures that provide a large surface area for the adhesion of microorganisms. Microorganisms on the sponge decompose organic materials in the water through processes such as nitrification and denitrification.
• Pollutant Degradation -Microorganisms consume organic pollutants as their source of energy and nutrients, leading to their degradation. The degradation process transforms complex organic molecules into simpler, less harmful forms.
• Disposal of Active Sludge – Over time, the biological film on the sponge becomes saturated and must be regularly removed to ensure the efficiency of the process. The removed biological film or active sludge can be further treated or used as compost.
• Final Treatment -After passing through the biological sponges, water can go through additional purification stages such as UV disinfection or sand filtration, to further improve the water quality before its discharge into the natural environment or reuse.

How to Install Separators i.e., the Method of Separator Installation.

Our separators are easy to maneuver, so installation can be done in one day. Typically, digging is performed. It is preferable for the base of the separator installation to be a concrete slab, and backfilling is done with sorted soil. It is necessary to adjust the working heights of the overflow edges, connect the inlet and outlet pipes, which must be buried at a sufficient depth.
