SchulzEP - Model WWS C -Water Sampler

• sampler of the new generation
• high sampling rate ensures maximum representative sample of water
• sampling frequency is controlled by time and depending on the current flow rate
• faster than the existing samplers
• more accurate than existing samplers
• unlimited sampling of water without any solid impurities
• sampler takes a sample each time through it flows through the water
• the sampling of the pressure pipe and open channel
• high suction depth up to 90 m, for the collection of open channel
• high mobility
• high reliability
• active tempering the sample at 0-4 ° C
• locked with two padlocks
• very easy operation

Comparison of water samplers new generation of WWS Continual sampling outdated structure with a peristaltic pump or vacuum system of sampling.

Nowadays we use outdated methods of sampling with peristaltic pump or vacuum system of sampling. These obsolete samplers sample taken at long intervals. Long interval between samples make it impossible for a representative sample whose quality should correspond to the flow through the water at the point of sampling. Today`s sampling interval to two hours is often insufficient and not representative.

Conventional outdated samplers do not affect the quality of the discharged water even during sampling type C. Very often it happens that the sampler for runoff from the sewage treatment plant takes samples every two hours and must start taking water when sampled point almost no water flows through. Most often this situation occurs when the offset sludge in the secondary sedimentation tanks or sewage where the influent pumping station. The sampler, which sampled at intervals of two hours, he must take a sample at a precise time interval during the sampling may not be changed. The sampler can then remove any water to us every ubyde twelfth slévaného sample and sampling thus becomes incorrect. I remember the case where the operator cleaners complained that the sampler has little water sample. On closer inspection we found

These deficiencies sampler removes WWS Continual by the sample throughout the sample with the smallest possible spacing which is 0.5 seconds when the sampling for one hour. The sampling interval is increased in proportion to the desired sampling period for sampling at 3.3 seconds for 8 hours and at a spacing of 9.7 seconds of sampling for 24 hours. After connecting the sampler to a flow meter, these time delays lengthened by instantaneous flow. The removed cumulated samples is quite proportional to the flow through the water, in other words the sample is representative proteklému volume and water pollution.

WWS Continual sampler can be locked by two padlocks that can pass the control to ensure sampler both the operator and the supervisory authority.

For operation samplers recommend:

• take samples continuously at each discharge using samplers WWS Continual
• samples stored in a dedicated refrigerator for three days, so that they are available for feedback control of the quality of the water has drained

WWS Continual Controlling samplers. Continual sampler WWS has a very simple and intuitive operation. With the four buttons on the control unit is very easy to set the start delay sampling length in hours and run the program. After starting the program sampler controls the water flowing through the sampling technology and the size of the instantaneous flow of external flow meter that measures the volume of water discharged. According to these values automatically adjusts sampler sampling program. Description of the basic display. A. icon - Sampling flowing water B. sampling time one hour C.
