LF Series Tablet Feeder - Flow surges are common in any treatment system. This variation in flow rate can cause major problems for conventional tablet feeders and manually adjusted gas or liquid chemical feed systems. The tiered flow deck will enhance the fluid dynamics of the liquids passing through the system. During low flow, usually at night, liquids are directed through the inert drainage tier, the lowest tier of the feeder. It forms a narrow hydraulic channel that increases the velocity of the flow for uniform tablet exposure. When flow increases during the morning hours, the liquid flow rises to the intermediate flow tier. It creates a flume to accelerate the flow passing the tablets. When the flow rate is greater than the capacity of this intermediate tier, liquids rise to the upper flow tier. That tier causes the liquid to lose velocity, preventing excessive tablet consumption.
The LF Series tablet feeders provide a chemical dose that is ideal for potable water and wastewater systems subject to high organic loading. Manufactured from ABS for durability and easy installation, integral inlet and outlet hubs accept four or eight inch piping.LF Series feeders are typically used for residential or small commercial onsite application, storm water treatment of remote potable water systems. Four different models are available to accommodate flows from a minimum of 75 GPD with the LF1000, through to a maximum of 400,000 GPD with the LF4800.
LF Series feeders range in length from 16 to 22 inches, and 7 to 12 inches in width. The 24 inch tall, one piece feed tubes are designed to fit inside standard 4' PVC piping, allowing all LF Series feeders to be surface installed or direct buried. For deeper installations, our optional remote feed tube removal system allows convenient feeder maintenance from grade. The above information is from Norweco.
