Procurement of Chemicals for the Operation of Water Treatment and Purification Plants

Reference Number : 2019/336

Hias IKS and Ringsaker Municipality invite tenderers to a contest for the delivery of chemicals for use in the processes at the sewage treatment plants and the water treatment plants owned by Hias IKS and Ringsaker Municipality. The plants are located in the municipalities Hamar, Stange and Ringsaker.

Main Site : Stange.

Hias' sewage treatment plant is located in Ottestad in Stange Municipality, and it annually treats approx. 8 000 000 m sewage water from approx. 130 000 person equivalents. The purification processes consist of mechanical, biological and chemical purification stages. Furthermore, thermal hydrolysis and anaerobe stabilisation of the sludge is carried out in accordance with the Cambi method. The sewage treatment plan mainly uses chemicals for treating sewage water and for dewatering sludge (polymer), in addition to using chemicals in the odour treatment processes.

The sewage treatment plant is currently being altered to biological phosphor removal. This means that chemical precipitation will be phased out as a process at the plant over a 2-year period. However chemical precipitation will remain at the storm water plant and as stand-by if the biological process fails.

Hias owns and operates 2 water treatment plants. Hamar water treatment plant is located in Hamar Municipality and produces approx. 3 500 000 m of drinking water per annum for approx. 30 000 persons in Hamar and parts of Ringsaker, L0ten and Stange Municipalities. The water treatment consists of corrosion control (marble and CO2) before the water is disinfected by adding chlorine and UV treatment. Stange water treatment plan is located in Stange Municipality and produces approx. 2 500 000 m of drinking water for approx. 19 000 persons in mainly Stange and L0ten Municipalities. The water treatment consists of filtration, adding chlorine and alkali silicate, and UV treatment.

Hias is in the process of constructing a new water treatment plant in Ottestad next to the current sewage treatment plant. The new water treatment plant will be ready autumn 2021. It will be dimensioned for a capacity of 400 litres/second. The process is precipitation in 3 media filters with marble at the bottom for alkalisation, as well as chlorine and UV as the last 2 hygienic barriers. The current plant at Hamar will be stopped and closed down after the new plant has been commissioned.

Ringsaker Municipality owns and operates 3 waterworks and 7 treatment plans, of which one treatment plant, Veslelien RA, is operated for Kirkens bymisjon.
