Pump station odor & corrosion control with chemical feed system
Romtec Utilities chemical feed system for wastewater pump station
Sewage pumping systems are frequently fitted with chemical feed for odor and corrosion control plus worker safety.
Wastewater collection systems, including pump stations, can be subject to the build-up of hydrogen sulfide gas (H2S), frequently the source of unpleasant odor and a serious cause for concern due to potential corrosion of concrete exposed to the gas. Operator safety is an even more serious matter, since breathing high concentrations of H2S is potentially lethal.
Romtec Utilities supplies odor/corrosion control chemical feed systems in its complete pre-engineered wastewater pump stations. The chemical feed system allows various chemicals to be introduced into the pump station’s wet well or into the force main. Siemens BIOXIDE® solution is the chemical most frequently specified by Romtec Utilities for control of odor, corrosion and safety problems associated with hydrogen sulfide in wastewater collection systems.
Variable drip rates can be operator controlled or automatically determined by process flow rates to achieve desired odor reduction at optimum chemical usage. In Romtec’s lift station chemical feed systems, two chemical feed pumps are typically utilized to provide two points of chemical application and full redundancy of this important part of the sewage pumping system. Features of the odor control chemical feed systems offered by Romtec Utilities include: digital display of chemical feed rate; alarm for loss of chemical flow; complete pre-assembly of pumps, valves, meters and controls; and a large cross-linked polyethylene chemical storage tank.
