Wastewater Treatment

The total scope is approx. NOK 3.5 million and includes filters for manganese removal, UV system, pressure boosting pumps with ejector system and two 30 m3 underground drinking water tanks. 30 m3 underground drinking water tanks. The contract included groundwork, prefabricated housing, automation, electrical, engineering and drawings.

Brimer had process responsibility for this turnkey contract. The delivery included complete process equipment for water treatment. The plant will produce drinking water for approximately 18,000 people in Kongsvinger and Grue. It is prepared to ensure supply to 2-3 more neighboring municipalities. The process consists of aeration of water with precipitation in a raw water pool, UV and dosing of water glass. The raw water source is a well park of five wells. It is prepared to expand to 8. The water had high levels of iron and manganese, which posed a challenge. The procurement concerned purification equipment, pipework and support for automation. The pipe arrangement is in dimensions from DN200 to DN500. The plant has a net production capacity of 950 m3/h and has two raw water pools of 1500 m3. They are also used for precipitation before UV. The project includes a pressure boosting pump station with 5 pumps (piping and foundations are prepared to increase to 7). Total capacity is now 950 m3/h against 125 mVs. There were also two DN400 pressure lines.

Here, Brimer supplied and installed pressure screens, UV systems (24 l/s), emergency chlorine systems, water glass dosing, chemical tanks and other pipe components for a new water treatment plant.

The contract covered the complete delivery, installation, adjustment and commissioning of technical installations for the upgrade of the water treatment plant. The delivery included UV units, electrotechnical installations (incl. PLC automation) and instrumentation for monitoring membrane filtration and UV. The scope was NOK 5.7 million and the plant was completed in 2022/2023 in accordance with the NS-8407 contract form.

Our tanks are white, bright and treated. This makes the insides easy to maintain and leads to low operating costs for the customer.

Such systems can replace larger underground systems. Having several tanks in a row gives you better control of the drinking water while facilitating cleaning and maintenance.
