In Shaker Type Dust Collector baghouses, tubular filter bags are fastened onto a cell plate at the bottom of the baghouse and suspended from horizontal beams at the top. Dirty gas enters the bottom of the baghouse and passes through the filter and the dust collects on the inside surface of the bags. Shaker baghouses range in size from small, handshaker devices to large compartmentalized units. They can operate intermittently or continuously. Intermittent units can be used when processes operate on a batch basis-when a batch is completed, the baghouse can be cleaned. Continuous processes use compartmentalized baghouses, when one compartment is being cleaned, the airflow can be diverted to other compartments. Cleaning a mechanical-shaker baghouse is accomplished by shaking the top horizontal bar from which the bags are suspended. Vibration produced by a motor-driven shaft and cam creates waves in the bags to shake off the dust cake.

Sheet pile cutoff wall is used in all types of water retaining structures to reduce the exit gradient at the downstream toe and prevent the chances of sand boiling and piping. It is used for excavation bracing and dewatering applications. It can be made of wood, reinforced concrete, or steel, with steel being the most effective material for constructing a ground-water barrier. The construction of a sheet pile cutoff wall involves driving interlocking sheet piles down through unconsolidated materials to a unit of low permeability.

Shockless ionizing gun is perfect for spot cleaning. It is designed for neutralizing static and removing surface contamination in non-clean room applications such as cleaning plastic parts prior to assembly. It is also used for neutralizing nonconductive components prior to their assembly into a printed circuit board.

Single point ionizing nozzles deliver neutralized air from long range. They blow away contaminants. A series installation allows it to be linked on a single cable. It is used on conveyor applications as well as stationary production cleaning and static neutralization is done.

The site engineering service provides plans and documentation and designs the site for the equipment to be used at the site. This service is available for new, upgrade or change-out installations, and applies to everything from simple nodes to complete system solutions. The service results in instructions and documentation for installing all associated equipment, including antennas, base stations, access cabinets, switches, routers, transmission and backbone equipment, cabling, and connections.

Site investigations are undertaken to establish the engineering properties of a site, the chemical constituents of a soil (including contaminants) and / or the position and quality of ground water at a particular location. For a construction project, the client or design engineer usually requires information from desk studies, risk assessments and site investigations during the planning stage. The design of the investigation depends on the type of information and level of detail that the client is looking for. Intrusive investigations should be designed to prevent the pollution of any underlying water-bearing strata, particularly where the land being sampled may be contaminated.
