### Lot Information

Lot 1

This description outlines the requirements for the rental of lime treatment equipment at Scottish Water's Allanfearn Waste Water Treatment Site to stabilise dewatered sewage cake. The equipment must ensure effective mixing of lime with sewage cake, precise dose control, and safe handling of materials. The supplier shall provide all necessary equipment, training, and maintenance support for the duration of the rental period. 

Scope of Supply 
The supplier shall provide a complete lime treatment system for hire, including but not limited to: 

Lime Storage Silo 
* A sealed, weatherproof silo with sufficient capacity for lime storage. There should be enough capacity to allow for a full load of quick lime to be added prior to running empty to allow for a continuous operation of the plant. 
* Dust suppression and venting to prevent environmental contamination. 
* Level indicators to monitor lime quantity. 
* A method of delivering the lime to the mixing unit in a controlled dose rate. 
* The silo should not interfere or require any adjustment to the infrastructure or buildings. 

Cake Import 
* A method of receiving cake import to the lime treatment plant 
* This should allow cake to be loaded into the lime treatment plant by a telehandler or other similar type plant. 

Twin Screw Auger Mixing System (or similar)
* A twin-screw auger mixer designed to homogenously blend lime with dewatered sewage cake. 
* Corrosion-resistant construction suitable for high-pH lime and sewage cake. 

Material Conveyance System 
* A mechanical conveying system to transfer sewage cake into the mixer. This should ideally be able to be fed automatically from the outlet of the centrifuge. 
* A mechanical conveying system to transfer lime into the mixer. 
* A mechanical conveying system to transfer treated cake to a clean area that will avoid cross contamination. 
* Compatibility with the dewatered cake's consistency (typically 20 -30% dry solids). 
* Minimal spillage and dust generation. 

Lime Dosing Control System 
* Automated dosing control to regulate lime addition based on sewage cake feed rate. 
* Measurement and adjustment of lime dose rate in kg lime per kg dried solids (DS) 
* Real-time monitoring with data logging of lime dosing control system. 

Safety & Environmental Controls 
* Dust extraction/containment systems. 
* Emergency stops and safety interlocks. 
* Compliance with health, safety, and environmental regulations.
