Amalgam UV Water Treatment Unit 100 m³/Hour – 4 Lamps

The Amalgam UV Water Treatment Unit 100 m³/hour is designed for industrial main lines carrying 75–100 m³ of water per hour.

The Amalgam UV Water Treatment Unit 100 m³/hour is used on main lines and at large plants where water has to be passed through ultraviolet light at high flow.

The Amalgam UV Water Treatment Unit 100 m³/hour passes the water through the ultraviolet light of four amalgam lamps. The US Environmental Protection Agency’s (EPA) ultraviolet technical guidance manual explains that amalgam lamps belong to the low-pressure high-output class and that the dose is the product of UV intensity and time.

1. 1

   The Water Is Filtered First

   Sediment, turbidity, colour, iron and manganese weaken the passage of UV light through the water. The water reaches the unit once it has passed through sand, carbon and, where needed, softening stages and has become clear.

2. 2

   It Enters the Body Through the Flanged Inlet

   Water enters the 304 stainless body through the 5 inch flanged inlet and flows around the four amalgam lamps in their quartz sleeves on its way to the outlet flange.

3. 3

   The Amalgam Lamps Produce UV Light

   The four lamps run at a combined 1,260 watts. The ultraviolet light disrupts the structure of microorganisms in the water and renders them inactive.

4. 4

   The Dose Is Set by the Flow

   The dose the water receives is the product of UV intensity and the time it spends in the body. For 300 J/m² the flow should not exceed 100 m³ per hour, and for 400 J/m² it should not exceed 75 m³ per hour.

5. 5

   It Is Monitored from the Panel

   As the water goes on down the line, the digital panel monitors lamp status and operating hours; it signals a fault with the indicator and an audible alert, and gives a warning when lamp life is up.

When choosing the Amalgam UV Water Treatment Unit 100 m³/hour model, line flow rate, target dose, water quality and installation conditions should be assessed together.

With regular maintenance the Amalgam UV Water Treatment Unit 100 m³/hour keeps its design dose and flow rate.

• Lamp service life is 9,000 hours. Even while a lamp still lights, its UV intensity falls; once this period is up the lamps should be renewed. The panel gives a warning when lamp life is up.
• If limescale, iron or sediment builds up on the quartz sleeves the UV cannot reach the water; the sleeves should be checked and cleaned regularly.
• Keep a regular eye on the fault indicator and audible alert on the panel; when a warning comes up, check the lamps and the panel without delay.
• Maintenance of the pre-treatment stages should not be neglected; cloudy water directly reduces the performance of the ultraviolet stage.
• While changing lamps or cleaning sleeves, disconnect the unit from the electricity supply and depressurise the body.
