Wastewater/Stormwater Samplers Product Description
Our new WS750 two-bottle wastewater/stormwater samplers combine all the features you need
to meet a wide variety of sampling requirements, including those for stormwater, industrial discharge, water and wastewater treatment,
waste collection systems, and rivers and streams.
The WS750 wastewater/stormwater sampler's state of the art controller gives you complete control over your wastewater/stormwater
sampling process. With the wastewater/stormwater sampler's sample size control, you can take individual time-weighted composite
samples or full-bottle discrete grab samples. The wastewater/stormwater sampler's sample interval control allows you set the
time between individual composite samples or enable the external trigger mode. A start delay timer allows you to start multiple
wastewater/stormwater samplers in the field at the same time, or to delay drawing a wastewater/stormwater sample after a triggering
event so that your sample better represents the water source. An automatic15 second backflush cycle clears any debris from the
wastewater/stormwater sampler's strainer and empties the water from the hose so the next sample is not contaminated.
A unique feature of the WS750 stormwater/wastewater samplers is the ability to set the sampling mode for each pump and bottle
individually. This allows you to take two individual time-weighted or flow proportional composite samples, or you can set the
stormwater/wastewater samplers to take full-bottle discrete (grab) samples, or you can set the stormwater/wastewater samplers to take
a full-bottle discrete (grab) sample in one bottle and a time-weighted or flow proportional composite sample in the other. In the
case of two composite samples you can have different size settings for each pump.
The WS750 stormwater/wastewater samplers are easy to set up in the field. The stormwater/wastewater samplers rugged rainproof
enclosure can be padlocked and/or chained to prevent tampering. The stormwater/wastewater samplers are enclosed in a relatively
small case that can be easily hidden or camouflaged to prevent vandalism. The stormwater/wastewater sampler's is lightweight enough
that even with a full sample bottle it can be suspended in a manhole for stormdrain or sewer sampling.
The WS750 wastewater/stormwater samplers come with two 1-gallon polyethylene sample bottles for collecting composite samples, two peristaltic
sampling pump, a circuit board controller, and a rechargeable gel cell battery. Also provided are two sample pickup hoses and a battery
charger. Everything you need is provided for a successful wastewater management or environmental monitoring program.
Low Power
The composite/discrete water sampler's 5 AH rechargeable battery will power the sampler for several months or a half hour of continous sampling
with both pumps.
Overflow Protection
The wastewater/stormwater sampler's sample bottles are each equipped with a float switch that automatically turns off the peristaltic sampling
pump if the water bottle becomes full.
Sample Size
The user can adjust the wastewater/stormwater sampler's peristaltic pumps individually to one of 15 composite sample sizes from 50ml to 2 liters
plus a full bottle discrete setting. The wastewater/stormwater sampler's peristaltic pumps can be set to a single sample time interval from
5 min. to 12 hours plus an external trigger mode setting for flow proportional sampling.
Flow Proportional Sampling
An external pulse-type flow meter can control the water sample interval for true flow proportional sampling. Global Water's
Open Channel Flow Monitor has a flow-proportional output signal for triggering the WS750 wastewater/stormwater
samplers. If you already have a flow meter but it has a 4-20mA output, please look at the related products section of the Wastewater/Stormwater
