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.
Using the new MSE System, Sunbelt Rentals is now able to filter the water contaminated with straw, soil, wood and other debris accumulated after the Trakway panels have been used.
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.
