The Federal Building Department of the Office for Building Regulations and Building Construction has renewed 5 fat separators in 3 barracks of the German armed forces Command Academy in Hamburg in order to be able to treat the greasy dirty and rinsing water from the kitchens safely in the future.

The aging concrete separators were replaced by modern GRP separators. Thanks to the glass fiber reinforced plastic material, the fat separators from Haase are permanently leakproof and chemically resistant without any additional coating or inliner.

In 4 systems, the manholes were already manufactured at the factory with the required inlet depths, with the fifth fat separator, the manhole was laminated on-site and could therefore be adapted seamlessly to the corresponding installation depth.

In this project, a privately inhabited house near Dresden was expanded by a small office building with a garage and technical center. Several energy sources are used to load the 30 m³ indoor pool and to support the heating of the two buildings: a heat pump with 20 kW, 13 m² tube collectors and a photovoltaic system. The electricity from the solar system is fed in via 2 heating cartridges, each with a power of 6 kW.
The intention of the operator: He wants to collect enough heat in summer that there is a correspondingly large reserve for pool heating in autumn and winter. This requirement made a large storage necessary.
The customer ultimately opted for a hot water tank from Haase. The decisive factors were the efficiency of the GRP storage, the very low heat losses and the optimal use of space that are possible with the storage from Haase.

The highway maintenance in Weißenberg in Saxony is responsible, among other things, for more than 65 km of motorway, 90 bridges and the “Königshainer Berge” tunnel, which is very important for the region. A new separator was also installed as part of the renovation of the washing area.

The durability of the Haase separators was decisive for the State Office for Road Construction and Traffic, in whose area the highway maintance fall: This means that in the medium and long term the total of acquisition, inspection and maintenance costs is lower than that of the competition.

The separator of nominal size NS10 installed in Weißenberg with sludge trap, petrol and coalescence separator and integrated sampling point is also characterized by the permanent tightness typical of Haase: the surface of the separator made of glass fiber reinforced plastic is chemically resistant, flanges and the dome shaft are laminated. The container wall has no joints that represent a weak point in concrete separators.

The bakery and confectionery Remke has almost 20 branches in North Rhine-Westphalia. A 15 m³ buffer storage from Haase has now been put into operation at the production facility. This is a central component of a waste heat recovery system, with the help of which large amounts of energy and thus costs can be saved.

A lot of heat is generated in the various manufacturing processes in bakeries, which unfortunately is often blown into the environment in the truest sense of the word. On the other hand, a lot of energy is required to heat the water that is used for cleaning processes.
In the Remke bakery, the waste heat is now loaded into the hot water tank by two flue gas heat exchangers, each with 50 kW, and a wood chip boiler. It heats the water when e.g. the baking molds, containers, machines and production rooms are to be cleaned. The heat is also used to heat the base load of the production building.

After the successful installation of a Haase fat separator in the Esslingen castle for the restaurant “Trödler zur Burgschänke”, the system for the “Ristorante Reichsstadt” in the historic center of Esslingen opposite the Old Town Hall was replaced. In both cases, the old and corroded steel separators were replaced by GRP separators. The Haase fat separators are permanently tight and stable up to the top of the terrain. This is achieved thanks to the dimensionally stable, aging-resistant and 100% corrosion-free glass fiber reinforced plastic (GRP) used in the manufacture.

Since the shaft is causing problems in many systems, it is already factory-made liquid-tight on the Haase fat separator made of GRP. This reduces the installation effort on the construction site and there are no joints that can leak.
In this way, the city of Esslingen has found a permanent solution, so that unsightly and complex construction and renovation measures on the fat separator system on the historic market place are a thing of the past.

Data to the fat separator:

• NS 7 fat storage: 400 l
• Sludge trap: 1,400 l
• Weight: 1,500 kg

A Haase fat separator with a nominal size of 20 was installed in the Lower Saxony AWO psychiatric center in Königslutter. The separator is used to separate greasy waste water from the kitchen. More than 1,000 meals a day are prepared here for psychiatric patients, the workforce, as well as surrounding kindergartens and schools.

The new fat separator was absolutely necessary because the old concrete tank had leaked and had to be repaired extensively for every regular leak test in the past 15 years. This, and the rental of a mobile separator that was necessary in the meantime, caused enormous costs, which are now no longer necessary with the Haase fat separator. In addition to the double-wall technology, this is guaranteed above all by the corrosion and chemical resistance of the glass fiber reinforced plastic from which the Haase fat separator is made. There are no deposits on its smooth inner surfaces.

Checks are easily possible thanks to the easy access via the DN 1,000 manhole. The spherical shape also makes cleaning much easier. The clinic will be able to use its new separator for a very long period of time without additional repair and maintenance costs.

Pickelmann GmbH also opted for a light liquid separator on glass fiber reinforced plastic. The energy trader supplies a wide range of customers with heating oil, fuels and lubricants as well as pellets. The company stores the water-polluting substances on the company’s premises in Betzenstein. The separator ensures the prescribed safety when filling the storage containers and when refueling the vehicles.

When it became clear that a new separator was needed for the company premises, it quickly became clear that the decision was made in favor of Haase. Mr. Pickelmann has already had good experiences with the above and underground heating oil tanks made of GRP. In particular, the liquid-tight dome shaft, which has proven itself in heating oil storage tanks for over 20 years, is one of the major differences from conventional concrete separator systems. The refurbishment costs incurred by the Pickelmann company in the shaft area are a thing of the past.

In October 2013, the time had come in the Reinsdorf district of Lutherstadt Wittenberg: the hot water tank system from Haase was put into operation at Reinsdorfer Fleisch- und Wurstwarenmanufaktur GmbH. “We have had a multi-stage system for the use of our production waste heat installed in our halls,” says managing director Pierre Kaaden. The closed cooling water circuit between two autoclaves for boiling and sterilizing sausage glasses reduces the drinking water requirement by around 6 million liters per year. In addition, there are about 265,000 kilowatt hours Energy that the Wittenberg company saves on hot water production. With an investment of around 25,000 euros, the system already pays off in the first year, according to Kaaden, since savings of 47,000 euros are expected.

The two autoclaves each have an output of 70 kW. The hydraulic integration of the hot water tank into the overall system is easy to implement. The serial integration means double savings. The hot water tanks can be integrated in the same way in the system flow as well as in the return by the loading and unloading pump without interfering with the existing control. The consumer groups alone take care of the loading (production waste heat) as well as the unloading (drinking water heating), to the extent necessary.

“I am two tanks” – that has been Haase’s slogan for decades. Our company is of course also developing further, the product range has been expanded considerably in recent years. Ultimately, however, everything revolves around containers made of GRP – the age and corrosion resistance of the material, the low weight, etc.

A Saxon manufacturer of precision castings made of stainless steel wanted to go new, sustainable ways when it came to the construction of an administration building when it came to heat supply. Steel processing generates very large amounts of waste heat, the sensible use of which can save a lot of money. In this case, excess heat from production is temporarily stored in two underground buffer tanks via the local heating network and used to heat the new building and to supply hot water.

Large quantities of food waste and other kitchen waste accumulate in commercial kitchens, canteens, hotels, catering facilities and communal catering – this waste of food is now being fought worldwide. Modern closed disposal systems therefore offer an economically and ecologically sensible solution for the recycling of food waste, and there is also no odor nuisance in the kitchen.

A major problem with the interim storage of organic waste is open and often too small storage containers, the handling of which is generally very uncomfortable and causes considerable hygienic problems. But how do you get a correspondingly large and permanently odor-proof tank into the installation room, whether right next to the waste recycling company or even at a further location? Doors or stairs are often an insurmountable obstacle for factory-made tanks.
