dri sludge distributors in bulk

dri Sludge suppliers that has been completely digested and stabilized by one of the aerobic or anaerobic methods should be gray in color and free of unpleasant odors. Such sludge has a high yield strength and its particle adhesion is very low. In order dri sludge distributors for such sludge to be removed from the treatment plant, its concentration must be increased so that the sludge concentration reaches 50 to 85%. If they want to package the sludge in powder form and provide it to farmers, its humidity must be more than 15%.dri sludge price perfect is great.

Mechanical methods for drying

The use of this method for dewatering sludge is very common in developed countries, but in Iran due to some problems such as lack of equipment for this method, equipment sensitivity, difficult driving and high energy consumption is not widely used. In all mechanical methods, the obtained sludge water must be transferred to the pre-treatment point of the biological treatment plant and re-enter the wastewater flow circuit of the treatment plant for treatment.

Method for Producing dri sludge

Due to the presence of some gas in the sludge and the bubbles coming out when it enters the bed, first the sludge clots come up in the form of foam and the sludge water collects at the bottom. Therefore, this sludge water must be separated from the sludge by a drainage system at the bottom of the bed.Usually, the dimensions of sludge dryer beds are 5 to 20 meters wide and 10 to 50 meters long, and of course, these dimensions are for the case where mechanical equipment is used to collect sludge. In manual mode the width should not be more than 4 to 5 meters. The collected sludge water must be returned to the wastewater flow circuit in the treatment plant at the point before the bioremediation units.

Bulk distributing dri sludge in 2020

Use of lakes or dry sludge pits These pits can do the job of drying sludge beds and even part of the sludge digestion process together. The height of the sludge in these pits can be selected between 1 to 3 meters. Such pits should be located in places where the groundwater level is low and away from the public environment, and the direction of the wind, the possibility of mosquitoes and unpleasant odors should be predicted.

These pits can do the job of drying sludge beds and even part of the sludge digestion process together. The height of the sludge in these pits can be selected between one to 3 meters, but it should be noted that the sludge was introduced in 20 cm layers in the pit and after drying, the next layer was added. In this way, it is possible to empty the dried sludge from the pit at intervals of every few years. To calculate the required level in these pits, the surface load entering these pits is selected to be close to one cubic meter of sludge per square meter of pit surface per year.
