In the Wastewater treatment plant, step screens are highly important and are considered to be one of the most important components. Step screens are installed in wastewater treatment plants, after separation of large waste solids, to protect equipment from damage or to avoid interruption of further treatment processes. For fine treatment and to collect waste of fine and medium sizes from industrial and domestic wastewater, which then removed and discharged to the transporter of the waste bin, step screens are intended.
Mechanical treatment is indispensable as the first process step of preliminary treatment of wastewater, both for STP inlets and other fields of application such as water treatment. Coarse material which causes disturbance needs to be removed in order to protect the subsequent steps against damage/pollution or to relieve them. The goal is to completely spate floating, settling and suspended material, depending on the bar spacing, and remove the material prior to discharging it into a container. The hygienic conditions, operation safety and the fact that there are nearly any maintenance works are factors becoming more and more important.
Stop logs are hydraulic engineering control elements that are used in floodgates to adjust the water level or discharge in a river, canal, or reservoir. Stop logs are mainly long rectangular timber beams or boards which are placed on top of each other and dropped into premade slots inside a weir gate, or channel. Present-day, the process of adding and removing stop logs is not manual but done with hydraulic stop log lifters and hoists. Since the height of the barrier can only be adjusted through the addition and removal of stop logs, finding a lighter and stronger material other than wood or concrete became a more desirable choice. The search for alternatives resulted in other materials like steel and composites which can be used as stop logs as well. Stop logs are designed to cut off or stop flow through a conduit.
