Sludge trap - Sludge traps - Sand trap

What is a sludge trap?

A sludge trap is a pit that is placed in the sewage system and its purpose is to remove settleable parts (sludge) from the waste water. A sludge trap ensures that a 'clean' discharge takes place into the sewer. A sludge trap protects the sewer from blockages and prevents the sewage treatment plant from being unnecessarily burdened. A sludge trap must be placed in the sewer system after the discharge point and before the connection to a separator which eventually discharges into the municipal sewer or surface water.
Are you obliged to install a separator? Then you are obliged according to NEN-EN1825 or NEN-EN858 to place a sludge trap in front of this. These can also be supplied as an integrated system. Sludge traps are used, among other things, to purify sedimentable parts. A sludge trap can be placed for an oil separator, coalescence separator, grease separator, but can also function separately as a purification of settleable parts. The sludge traps are produced in accordance with NEN-EN1825 or NEN-EN858 standard.

 

Oil separator with sludge trap

To separate mineral oil from water in a simple way, use an oil separator. The size of a petrol separator depends on the quantities of oil and water. Oil separators are used in places where there is a greater chance of mineral oil being discharged. Think, for example, of washing passenger cars and trucks. But also at workshops where people tinker with motor vehicles or at a gas station. We offer you a complete and certified separator program. All our separators comply with the European standard NEN EN 858.

The fuel separator

Oil and its related oil products, such as gasoline and diesel, are extremely dangerous and bad for the environment when exposed. Yet it is these oil products that are indispensable to keep our economy going. These products are almost always found in vehicles, such as cars and trucks. Sometimes there is a tendency to leak in the engine and then you can immediately see what damage oil products can cause. A large oil spot with distinctive rainbow colors appears on the road surface and is difficult to get rid of with water. Try to imagine what if such products end up in the environment and affect water and animals. This is why companies that work with oil products are obliged to use a separator. A petrol separator is, for example, widely used in car garages, parking garages, petrol stations and car washes. This prevents petrol and diesel from entering the municipal sewer system or surface water.

How does the oil separator work?

A gasoline separator is also called an oil separator or hydrocarbon separator. Hydrocarbons are the components in crude oil that should absolutely not end up in open water. Together with water and other oil products, these hydrocarbons are discharged as waste water via a concrete tank, the actual petrol separator. Since the density of these hydrocarbons is much lower than water, they will separate in this pit and come to the surface. The separator has an automatic shut-off valve. This valve, also called a float, only floats on the water. The water will be discharged through the exit to the sewer or open water. The more oil that enters the tank, the lower the water level will be. As a result, the float will also sink more and more downwards. At a certain point, he closes the exit and no more water can be drained. This is a sign that the tank is full of hydrocarbon and needs to be cleaned. There are separators with and without sludge trap. Space is then reserved in the pit for sludge that has come along. If this is not present, a separate sludge trap must be installed.

 

Coalescence separator with sludge trap

To easily separate mineral oil from water, use a coalescing separator when discharged into open water. The size of a coalescing separator depends on the amounts of oil and water. A coalescing separator is used in places where there is a greater chance of mineral oil being discharged. Consider, for example, distribution centers, port areas, when washing passenger cars and trucks. But also at workshops where people tinker with motor vehicles or at a gas station.

The coalescing separator

Oil and its related oil products, such as gasoline and diesel, are extremely dangerous and bad for the environment when exposed. Yet it is these oil products that are indispensable to keep our economy going. These products are almost always found in vehicles, such as cars and trucks. Sometimes there is a tendency to leak in the engine and then you can immediately see what damage oil products can cause.

This prevents petrol and diesel from entering the municipal sewer system or surface water.

How does the coalescing separator work?

Coalescence separators are also known as oil separators or hydrocarbon separators with an additional filter. Hydrocarbons are the components in crude oil that should absolutely not end up in open water. Together with water and other oil products, these hydrocarbons are discharged as waste water via a concrete tank, the actual petrol separator. Since the density of these hydrocarbons is much lower than water, they will separate in this pit and come to the surface. The separator has an automatic shut-off valve.

Grease separator, Grease pit, Grease trap

DWTN can help you in your search for a grease separator. We supply a complete and certified separator program with CE-marking and/or KOMO-approval. All our grease separators comply with the European standard NEN EN 1825. As a result, you can be sure that you are buying reliable products with a proven effect.

Grease separators for different applications

We offer a suitable grease separator for various applications. There are, for example, variants for control/sampling wells and sludge traps. But we also have grease separators for catering . These are suitable for kitchens of restaurants, snack bars, hotels, nursing homes, hospitals, canteens, bakeries, butcher shops and food technology. In short: you can find a suitable grease separator for many different workplaces with us.

But why is a grease separator necessary?

When animal and vegetable fats, oil and sludge enter the sewer, this can have unpleasant consequences. For example, the sewer can become clogged, with all the associated consequences. Cleaning a sewer costs a lot of money (and time) and if grease and sludge continue to get into it, the blockage will keep coming back. Here the rule is: prevention is better than cure. This problem mainly occurs in areas where a lot of grease and oil is used. Think of kitchens in restaurants, nursing homes and schools. According to the Environmental Management Activities Decree, certain sectors must separate their wastewater from grease and sludge. This can be done by installing a grease separator.

How does a grease separator work?

A grease separator works on the basis of gravity. The waste water, which comes from a kitchen, for example, ends up in the separator. The heavier parts of the fat and oil sink to the bottom and form a layer of sludge there. Because fat has a lower density than water, it will float to the surface and solidify there. The water is discharged to the sewer through the exit of the separator. This process usually goes well and not much can go wrong. It is usually also quickly clear when the grease separator needs to be cleaned. Over time, the layer of sludge and the layer of fat come closer together. As a result, there is less room for the water, which ensures that the flow decreases. Then it's time for a cleaning.

Different types of grease separators

A separator can be in the ground, but there are also examples that are in a basement or other space of a building. If you need a large, built-in separator, it is best to choose a concrete grease trap or a polyethylene variant. You can contact us for CE-approved plastic grease separators, CE-approved concrete grease separators and KOMO-approved concrete grease separators. We also have separators made of stainless steel in our range.
