The RDS1™ Trickling Filter Rotary Distributor is engineered to evenly distribute wastewater over filter media. The wastewater trickles down through the media, contacting the attached biological growths. The growths then oxidize the pollutants in the wastewater.
The RDS1 Trickling Filter Rotary Distributor sets the standard, offering superior design and operational benefits over all other rotary distributors:
Bearings: WesTech engineers all Trickling Filter Rotary Distributors with two anti-friction bearings designed for a life of over 30 years. The upper bearing supports all thrust loads exerted on the mechanism while the stabilizing bearing and upper bearing resist the overturning loads. Both bearings are positioned above water level. Bearing contamination and corrosion are eliminated providing longer service life. The bearings are accessible and maintenance is easy.
Pan Test: WesTech guarantees each of our Trickling Filter Rotary Distributors to pass a pan test which demonstrates that the arms are providing uniform flow distribution over the surface of the filter, at minimum and maximum flow conditions. Flow uniformity is a critical measure of the mechanism’s efficiency and is designed into each WesTech Rotary Distributor.
Spreaders: WesTech flow spreaders are made of virtually unbreakable, corrosion-resistant, UV-protected polycarbonate. They are guaranteed against breakage for the life of the Trickling Filter Rotary Distributor. WesTech flow spreaders are solidly connected to the arm using a single bolt for quick assembly and removal. Inside each spreader port are fixed-size replaceable orifices which cannot be tampered with, unlike the slide plate-type orifices. This assures that the flow distribution will continue as designed by the engineer.
Lower Seal: A maintenance-free lower seal is designed with a polished stainless steel seal ring. Maintenance is not necessary providing for uninterrupted, worry-free operation. Also, this lower seal design requires a lower hydraulic head than the seal-less barrel design.
Weir: An adjustable inner feedwell weir produces an efficient operation at low head levels in distributors where a high ratio of maximum to minimum plant flow is required.
Flushing Gate: A pinned and latched flushing gate on the end of each distributor arm allows for a trouble-free flushing of any debris.
