The residue accumulating in sewage treatment plants is known as sludge. Sewage sludge is the solid, semisolid, or slurry residual material which is produced as a by product of wastewater treatment processes. This residue is commonly classified as primary and secondary sludge. The primary sludge is generated from chemical precipitation, sedimentation, and other primary processes but the secondary sludge is the activated waste biomass which results from biological treatments. Some sewage plants receive septage or septic tank solids from household on-site wastewater treatment systems. Quite often the sludges are combines together for further treatment and disposal.
The management of sludge originating from wastewater treatment is a highly complex and costly activity, which if handled poorly, will jeopardise the environmental and sanitary advantages, expected in the treatment systems. With the increasing demands from society and environmental agencies towards a better environmental quality standards have manifested themselves in public and private sanitation service administrators. Due to the low indices of wastewater prevailing in several developing countries, it can be easily expected that a future increase in the number of wastewater plants. As a consequence, the amount of sludge produced is also expected to increase. And with this it can be anticipated that the needs for Sludge Treatment Equipment are also bound to rise up. At Dutco Tennant LLC, we recognise this ever increasing demand and want to diminish it with our range of solutions.
Dutco Tennant LLC is a trusted supplier of all types of Sludge Treatment Equipment in the Middle East and GCC region. Over the span of four decades, we have been supplying to the Middle East, with a varied range of products like Scrapers, Primary and Secondary Clarifiers etc. We supply scrapers and clarifiers which are designed by the biggest brands in the industry. Their design has been made based on static calculations and its engineering expertise. The appropriate calculation of sludge load and mass, leads to a strong and reliable work process. As a result, the dead points in the sedimentation or thickening tanks are eliminated.
