Sewage Treatment plants
Commercial Wastewater Treatment Plant
Case study overview
Date
December 2021
Location
Oykel Bridge, Lairg
Industry Sector
Commercial – Hotel
Product Used
Tricel Maxus wastewater treatment plant (92PE)
Project Introduction
Located in Sutherland between Bonar Bridge and Lochinver, the Oykel Bridge Hotel offers guests an opportunity to see some of the most beautiful scenery in the Scottish Highlands.
The hotel reopened on April 26th 2021, after remaining closed for the remainder of 2020.
The hotel was looking at upgrading its septic tank with a commercial wastewater treatment plant.

THE CHALLENGE
The Oykel Bridge Hotel wished to upgrade their old septic tank by implementing a commercial wastewater treatment plant as part of its enhancement and development initiatives.
The sustainable economic development in Scotland relies on the sustainable management of a range of natural resources and services, and so it was particular important that the hotel’s upgraded wastewater system reflected that.
As a non-departmental public body, the Scottish Environment Protection Agency (SEPA) ensures that the environment and human health are protected. In order to minimize the risk of contamination of local waterways, the ammonia concentration for this application must reach a dilution level of 5 mg/l.
The Installation
To ensure that the plant was designed and specified to meet the needs of the hotel, we sized a 92PE Tricel Maxus wastewater treatment plant system with a buffer tank to meet an ammonia level of 5mg/L.
During off-peak seasons, energy costs are also reduced because the pumps on the tank work with the flow. We have designed our wastewater treatment plants to handle seasonal loads and constant loads. The control panel will be optimized automatically according to the amount of incoming loads and effluent strength.
TRICEL SOLUTION
The Tricel Maxus is designed to handle wastewater exceeding 50 Population Equivalent (PE).
To meet the required treatment level, the Tricel Maxus commercial wastewater treatment plant was chosen. It uses a Submerged Aerated Filter (SAF) system with a control panel E-III which controls all electrical components of the plant. It is easy to install and comes with various configuration options that can be tailored to nearly any site. As well as being easy to use, it can also be easily maintained.
Moray Munro, the contractor, had already worked with Tricel on past projects and was satisfied with the solutions provided. Indeed, he had installed a domestic wastewater treatment plant through Highland Plumbing and Heating Supplies, a Merchant in Tain.
During the treatment process, the bio sludge settles in the clarifier. The bio sludge from the bottom of the tank is recirculated back to the settlement tank by the airlift pumps. After the liquid has been treated, it can be discharged.
The submerged aerated filter (with a large surface area for microbes) aerates the wastewater as it passes through the biological treatment zone. Aeration is matched to the incoming flow using the control panel for efficient operation. Chemicals and maintenance are not necessary.
