SECTION II. EQUIPMENT DESCRIPTION AND DATA.
1-7. EQUIPMENT CHARACTERISTICS, CAPABILITIES, AND FEATURES. The hypochlorination unit is designed to
chlorinate water in a water supply line before or after storage, and is capable of feeding hypochlorite solution in direct
proportion to water demand over a range of 2 gpm to 350 gpm. It can operate in a temperature range of 32° F to 140° F.
It is a light weight, independent unit that can be carried by two men and has little maintenance. It is easily operated by
one person who only needs to check unit periodically after start up. It is provided with quick connecting camlocks making
it easy to install, secure, or replace for maintenance.
1-8. LOCATION AND DESCRIPTION OF MAJOR COMPONENTS. The hypochlorination unit consists of following
major components:
1.
Accessory Box is provided for storage and transportation of chlorine analysis kit and miscellaneous equipment.
2.
Ball Valves are used to isolate proportioning pump for maintenance.
3.
Camlock Fittings connect hypochlorination unit to hose from unchlorinated water supply on inlet side and to
hose going to chlorinated water holding tank on discharge side.
4.
Chlorine Analysis Kit is provided to test treated water for chlorine residual concentration and is stored in
accessory box.
5.
Frame Assembly supports individual components and allows for ease of transportation.
6.
Mainline Pipe is pipe through which bulk of water flows during treatment.
7.
Proportioning Pump is a chemical metering pump. It measures water flow and adds hypochlorite solution to
water flow in direct proportion, and is completely water powered.
8.
Range Adjusting Valve is a butterfly valve used to control amount of water sent through proportioning pump.
This allows for a wide range of flow rates with greater accuracy.
9.
Solution Reservoir holds hypochlorite solution to be drawn into proportioning pump.
10.
Y-Strainer holds a screen that filters out particles and protects proportioning pump from damage or clogging.
