There are usually some failures during the commissioning and operation of the screw press sludge dehydrator. It is necessary to clarify the reasons to make timely adjustments, improve the performance. Failure A: Sludge Clogging. Solution: If it is slightly clogged, try to reverse the screw shaft. If blocked seriously, screw cylinder need to be disassembly…

The screw sludge dewatering machine becomes one of main sludge processing machine in the wastewater industry. And the market is flooded with numerous OEM manufacturers, then how to evaluate the configuration of a screw sludge dewatering machine is important to get right one for your purpose. Some basic judgement standard for reference. Material As the…
Industrial water treatment systems take a variety of forms. Among the most common include the dissolved air flotation system, the water oil separator system, the aerobic treatment system, and the induced gas flotation system. These water treatment systems vary from one another in both their principles of operation and the purposes for which they were…
The so-called electrolytic air flotation method is a method of air flotation water treatment. During the electrolysis process, under the action of a direct current electric field, tiny bubbles of hydrogen and oxygen are generated at the cathode and anode respectively, which have a chemical redox effect on the pollutants in the wastewater, and can…
Low energy consumption, small footprint, high cost effectiveness and wide range of applications make the screw sludge dewatering machine a dramatic rise in industrial wastewater treatment. High efficiency and automation are the unanimous praise of users. So how does it work? Here is a brief introduction to its working principle and main components. The dewatering…
The way to effectively prevent excessive use of PAM and PAC is experimentation. Small experiments, field trials, etc, or use PAM to judge the amount of PAM and PAC by observing the water quality. We know that PAC is a water treatment agent that destabilizes and agglomerates colloids, and PAM is a water treatment agent…
A great way to deal with algae, fat, oil and grease (FOG) is to install a Dissolved Air Flotation (DAF). However, many face difficulties in operating the device and therefore, plant fails. First of all, it is important to know which type of DAF are you integrating in your system; whether it is a gravity…
Dissolved Air flotation is mainly used to remove suspended impurities density of which is closed to that water. These impurities can not either settle naturally or float naturally. DAF has the advantages of high separation efficiency and simple structure. The dissolved air flotation will directly affect the effluent quality. The poor effect of the dissolved…
Physical solid-liquid separation processes rely on the density, size, or shape of the individual particles. They usually involve settling by gravity, screening, or centrifugation. A basic requirement for the efficient separation of swine manure is the continuous agitation of the liquid that is processed. Otherwise, relatively fast sedimentation occurs that leads to reduced separation or…
