Wastewater/StormwaterSamplers Product Description
Our new WS750 two-bottle wastewater/stormwater samplers combine all the featuresyou need to meet a wide variety of sampling requirements, including those forstormwater, industrial discharge, water and wastewater treatment, wastecollection systems, and rivers and streams.
The WS750 wastewater/stormwater sampler’sstate of the art controller gives you complete control over your wastewater/stormwatersampling process. With the wastewater/stormwater sampler’s sample sizecontrol, you can take individual time-weighted composite samples or full-bottlediscrete grab samples. The wastewater/stormwater sampler’s sample intervalcontrol allows you set the time between individual composite samples or enablethe external trigger mode. A start delay timer allows you to startmultiple wastewater/stormwater samplers in the field at the same time, or todelay drawing a wastewater/stormwater sample after a triggering event so thatyour sample better represents the water source. An automatic15 secondbackflush cycle clears any debris from the wastewater/stormwater sampler’sstrainer and empties the water from the hose so the next sample is notcontaminated.
A unique feature of the WS750 stormwater/wastewatersamplers is the ability to set the sampling mode for each pump and bottleindividually. This allows you to take two individual time-weighted or flowproportional composite samples, or you can set the stormwater/wastewatersamplers to take full-bottle discrete (grab) samples, or you can set thestormwater/wastewater samplers to take a full-bottle discrete (grab) sample inone bottle and a time-weighted or flow proportional composite sample in theother. In the case of two composite samples you can have different sizesettings for each pump.
The WS750 stormwater/wastewater samplers areeasy to set up in the field. The stormwater/wastewater samplers ruggedrainproof enclosure can be padlocked and/or chained to prevent tampering. The stormwater/wastewater samplers are enclosed in a relatively small case thatcan be easily hidden or camouflaged to prevent vandalism. The stormwater/wastewatersampler’s is lightweight enough that even with a full sample bottle it can besuspended in a manhole for stormdrain or sewer sampling.
The WS750 wastewater/stormwater samplers comewith two 1-gallon polyethylene sample bottles for collecting composite samples,two peristaltic sampling pump, a circuit board controller, and a rechargeablegel cell battery. Also provided are two sample pickup hoses and a batterycharger. Everything you need is provided for a successful wastewatermanagement or environmental monitoring program.
Low Power
The composite/discrete water sampler’s 5 AH rechargeable battery will power thesampler 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 afloat switch that automatically turns off the peristaltic sampling pump if thewater bottle becomes full.
Sample Size
The user can adjust the wastewater/stormwater sampler’s peristaltic pumpsindividually to one of 15 composite sample sizes from 50ml to 2 liters plus afull bottle discrete setting. The wastewater/stormwater sampler’speristaltic pumps can be set to a single sample time interval from 5 min. to 12hours 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 trueflow proportional sampling. Global Water’s OpenChannel Flow Monitor has a flow-proportional output signal for triggeringthe WS750 wastewater/stormwater samplers. If you already have a flow meterbut it has a 4-20mA output, please look at the related products section of the Wastewater/StormwaterSamplers Options & Prices section
