• Dutco Tennant LLC, PO Box 233, Dubai, U.A.E.

Dutco Tennant Supplies the most efficient and best in performance rotary distributor that is available in the market. The trickling filter is designed for evenly distributing wastewater over filter media. For wastewater treatment, Trickling filters can be a reliable part of wastewater treatment plants. We supply completely hydraulically driven Trickling Filters. They come with automatically adjusting gates which are controlled pneumatically for opening and closing the orifices in equal proportion on both sides of the distributor's arms. There is also a sensor at the center assembly which transmits speed readings to the control box that automatically adjusts the speed for matching the present operational or flushing program. With the varying flow to the trickling filter, the speed is maintained by adjusting the gates over the orifices automatically.

Environmental standards for water discharge, mainly from wastewater treatment facilities or systems are gradually falling into the subject of more stringent effluent requirements. Among all the requirements, the need for keeping systems and facilities up to date with the modern environmental regulations is the most important. Tertiary Treatment is necessary for some of these regulations to a new or existing Secondary Wastewater Treatment System for further reduction of BOD and TSS as required by Federal and Local Authorities. Tertiary filters are required for filtering the liquid effluent from a secondary wastewater treatment system. Assistance for additional removal of suspended solids from the secondary effluent and a further reduction of the biochemical oxygen demand is provided by Tertiary sewage treatment. In two parallel flow filter cells, the filtering takes place and each of them contains filter media that consists of a layer of anthracite along with a sand layer through which the liquid flows.

For several decades, hydrodynamic separators have been in use as a primary treatment device for stormwater. They are also referred to as oil-grit separators, vortex separators, or swirl devices and are the best structural management practices that are used for treating and pretreating stormwater runoff. These systems are underground structures and are typically made up of concrete with internal components which creates a swirling vortex for enhancing particle settling. Sedimentation is the most common mechanism that lies behind particle separation as characterized by Stokes’ Law. These systems often contain internal components which are designed for reducing water velocity and preventing turbulence that decreases resuspension of previously captured pollutants. Some of them also incorporate screening technology for enhancing the removal of trash and debris.

The oil separator is a device that is used for separating lubricating oil from the exhaust water vapor or compressed gas. Oil Separator is termed as an element of transferring installations and compressed moist gas. An oil separator operates by utilizing the difference in the values of the inertial forces that act on the drops of oil and the considerably less dense particles of their gaseous environment.
