Focus on the customer: shortened delivery time for cell inserts

February 2021
Keeping downtimes to a minimum is the goal of any efficient production - which is why the replacement of parts and maintenance work should take place in the same time window if possible. This only works with a partner who puts customer requirements first. An internationally active chemical company ordered cell inserts for the BHS rotary pressure filter with a standard delivery time of eight months - but needed them a whole two months earlier. BHS made this early delivery possible to keep to the customer's schedule.

FGD gypsum: indexing belt filter deployed in Scandinavia

November 2020
BHS-Sonthofen is helping a power plant in Scandinavia transform a waste product back into a raw material: high-purity FGD gypsum with a residual moisture content of 10% (90% solids) can be resold directly to the construction materials industry. Since 2007, the power plant has been operating a flue gas cleaning system that uses a BHS indexing belt filter (BF). An additional filter has now been ordered. The combustion processes produce flue gas that is contaminated with sulfur compounds. Milk of lime is used to remove the sulfur compounds. Gypsum slurry is produced as a by-product, the residual moisture content of which must be brought down to 10% and any corrosive compounds need to be removed. The BHS indexing belt filter performs both of these tasks using its efficient cake washing. The system has been running smoothly since it was installed.

Moistening incinerator bottom ash with the BHS pug mill

October 2020
Waste is turning into an increasingly important source of raw materials. Even incinerator bottom ash still contains a large number of materials that can potentially be recycled. Metals such as iron, copper, and aluminum make up about ten percent of the ash. But what happens to the non-recyclable fraction? It must be deposited in landfills in a safe manner for as long as possible. However, operators of waste incineration plants face the challenge that incinerator bottom ash emits a considerable amount of dust. A North American waste incineration plant operator therefore decided to humidify the ash using a total of five BHS pug mills. The mixers of type AVA HTK now reliably convert the ashes into a dust-free, transportable product at three sites.

Dryers for high-purity plant proteins

September 2020
Plant proteins often form an essential part of a vegetarian or vegan diet, which is why they are in high demand. However, several process steps are required to obtain high-purity plant proteins suitable for human consumption from almonds, sunflowers or quinoa, for example. One of the challenges is the final drying process. BHS-Sonthofen has supplied a special dryer for this purpose to a German plant protein producer.

Reactive ashes: Italy's largest energy supplier uses AVA mixers

December 2019
Fly ash, which is produced during incineration for energy generation, contains highly reactive substances such as free lime (CaO). For this reason, it must not go to landfill untreated, but must first be conditioned in a multi-stage process. In order to carry out this demanding process safely and efficiently, one of Italy's largest electricity suppliers equipped its power plant with AVA mixers from BHS-Sonthofen.

Indexing Belt Filter (BF) Used for Herbal Extract Production in Switzerland

October 2019
A Swiss pharmaceutical company has successfully deployed an indexing belt filter (BF) to produce an herbal extract using an extraction and filtration process.
