Bilfinger Water Technologies designs and builds complete water recovery and slurry dewatering systems for sand and aggregate washing plants. These high-performance systems minimize water usage and solid disposal problems.
The dewatering phases in municipal processes are basically of biological sludge originated from purification processes. Bilfinger Water Technologies has realized many complete installations of sludge purification regarding the processes of water purification, purification of waste waters and SUW (solid urban waste) treatment.
The principle cause of regional and urban haze, or visibility impairment, is light extinction caused by fine particles, sulfates, organic and elemental carbon, nitrates and crustal matter. Particles between 0.1 and one micrometers in size are most effective at scattering light, in addition to being of greatest concern for human health.
Room Acoustics concerns the way sound is created, propagated, perceived, measured and modelled inside enclosures. Enclosures can be dwellings, offices, workshops, factory halls, lecture rooms, auditoria, concert halls, transportation terminals, etc. Reverberation Time is the single most important parameter used to describe Room Acoustics, but in addition, parameters describing music quality and speech inteligibility are important.
Environmental noise is unwanted sound and vibration coming from a plethora of sources, among them industrial plants, road and rail traffic, construction work, and aircraft. Add to these sports events, shooting ranges, leisure parks, etc, and you have noise from many different sources, each with different characteristics and posing specific problems for the professionals who have to assess them. The way the problems are dealt with differs immensely from country to country and is very much dependent on culture,...
Sound Intensity is the measure of acoustic energy passing through a unit area. By integrating over a surface enclosing an object under test, you can calculate the object`s sound power. This can be done regardless of background noise, allowing convenient, in situ measurements of sound power. Other advantages of sound intensity measurements include the ability to determine the directionality of sound, and to quickly localise noise `hot spots`. Mapping software takes this a stage further by providing you with a...
Before you can determine what design changes are appropriate to reduce the noise emitted by a product, you need to be able to characterise it in terms of: Spectral content: The location of the dominant sources. The relative importance of dominant sources. Noise Source Identification employs a number of tools to perform such a characterisation.
Many analytical tools used for research and development focus on making single measurements, and are designed accordingly. However, in many industries, test programs are performed that involve large numbers of repeated tests on test objects in various configurations or with various modifications. This is repetitive testing. The tests done are generally standardised, and often performed in a dedicated test area.
The construction sector and its wide range of associated activities are very varied and from a noise monitoring perspective offer many unique challenges. However, Pulsar Instruments have a solution; a construction Pulsar noise meter with the ability to effectively assess the following two key categories; Noise at Work (potential for noise induced hearing loss due to long term exposure to noisy activities). Environmental Noise (the potential to cause annoyance to surrounding areas or buildings during site work).

STS pressure transmitters and transducers are ideal for a variety of applications in machines and plant construction. Sensors from STS are installed on the harbour doors of Rotterdam Port, which protect the city against storm tides. STS has many years of experience in process automation of hydraulic monitoring and in plant construction.
The development and optimization of new engines and machines requires extensive tests to take the next step. STS produces easily customizable, highly precise pressure sensor technology for a great variety of applications for test facilities and prototyping.
Hydrogen Fluoride (HF) is a colorless gas that is used extensively in industrial applications. Fluoride monitoring is especially needed for aluminum plants that need to convert HF into fluorine for use in their processes. Any HF that escapes is a cost to the plant, so an HF analyzer is essential to keep track of and prevent the losses.
Engine and vehicle emissions testing involves complex routines and audit regimes to meet with exacting modern legislation. The methods for measuring gases are also prescribed by the relevant authority and so you might imagine that the equipment for emissions testing is all the same. Signal take a different approach to our competitors. By designing bespoke systems from a selection of standard modules, we supply all the equipment and features you require, but nothing that you don`t. This makes our systems the...
The roads and bridges construction and repair demand of careful investigation of road surfacing state, quality of used concrete and geological assessment of ground structure under roads to find any heterogeneity. GPRs can be applied here for: tunnels, road surface thickness measure, runways state assessment. The important advantage of GPRs using – quick road surface assessment.
The real-time monitoring of odorous gases or more classical pollutants emitted by industrial sites (wastewater treatment plants, refineries, landfills, etc.) appears nowadays as a requirement, in order to optimize the site process and operations, or communicate towards the neighborhoods and local public bodies.
While emissions can be measured directly at the source (in the stack, exhaust, etc.), ambient air measurement all around the sites provides a better accuracy and anticipate pollution episodes. This is why...
