MSE Systems has provided equipment hire firm Sunbelt Rentals with a fully automated wastewater treatment system following a successful rental and testing period in 2020.
The firm was asked to provide a system that would dramatically reduce the amount of fresh water used by Sunbelt Rentals when cleaning the dirty Trakway panels ready for use by new customers. Trakway is a series of panels laid down to create access to fields and sites that are usually inaccessible to vehicles and pedestrians.
Cleaning the panels uses a lot of water and the firm wanted an economical and sustainable solution which recycled the used wash water.
MSE Systems designed a complete packaged plant that included heavy duty feed pumps, tanks, lamella settling unit with automated control (pictured), containerised chemical dosing systems, and a complete sludge dewatering and conveying system.
A high-performance compact Lamella settling tank administers chemical dosing and pH correction to ensure the freshly cleaned water is then overflowed back to the water holding tank for re-use.
The settled solids, which are monitored by torque control on a mixer, are transferred from the base of the Lamella to the sludge holding tank where they are stored prior to processing and dewatering in a containerised MSE Hiller sludge dewatering centrifuge system.
The discharge water from the centrifuge system is clean and discharged back through to the start of the system to ensure a robust recycling process that is safe to be used again and again in the high-pressure wash system. The solids leave the centrifuge as a stackable soil-like cake material at 55 – 75% dry solids and, in doing so, further reduces Sunbelt Rentals’ environmental impact.
