Dewatering bag is useful for pumping silt and sediment laden water from a construction site. It is an outlet protection device used to filter sediment from a pump discharge when dewatering a trench or similar excavation in the course of construction. It is designed to control sediment discharge in dewatering operations. It can be easily installed onto the discharge hose. It is portable & easy to remove.

Dilution extractive continuous emissions monitoring systems are designed for continuous emissions monitoring of gases such as NOx, SO2, CO, H2O, and O2. It is ideally suited to installations where there are long distances between analyzer and measuring point. It is also easily expanded for other gases, is simple to install and has a low maintenance requirement.

The direct-fired thermal oxidizer is mainly used for thermal oxidation process. A process stream is introduced into a firing box through or near the burner and enough residence time is provided to get the desired destruction removal efficiency of the VOC'S. Also called afterburners, these systems are the least capital intensive, but when applied incorrectly, the operating costs can be devastating because there is no form of heat recovery. These are best applied where there is a very high concentration of VOC'S to act as the fuel source for complete combustion at the targeted operating temperature.

Drain insert is ideal for drains. It helps keep hydrocarbons and sediment from entering drains and the water system. It contains filter strips that remove floating oil and other hydrocarbons. It is equipped with a heavy-duty tension rot that secures the drain. This insert is also used as the initial step in removing trash and some particulate matter, oils, and greases. It fits into storm drain inlets and contain trash racks and a small amount of filter media to remove sediments and some dissolved constituents.
