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.
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.
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.
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
