What is silicate measured for?

Silicate (SiO₂) is a dissolved ingredient that occurs in almost all natural waters. Monitoring the silicate concentration is particularly important in the following areas:

• Power plants and steam generation: At high temperatures and pressures, silicate forms extremely hard, glass-like deposits on turbine blades and in steam pipes. These deposits are almost impossible to remove and lead to considerable efficiency losses.
• Boiler feed water: Even low silicate concentrations can cause damage in the high-pressure range. Typical limit values are in the range of a few µg/l.
• Reverse osmosis systems: Silicate can irreversibly foul membranes (silica fouling). Monitoring the permeate protects against costly membrane damage.
• Mixed bed ion exchanger: Control of the exchange capacity – silicate is often one of the first parameters to break through during depletion.

How does the Reagent work?

The silicate Reagents consist of a reagent set with several components for fully automatic silicate determination with the SYCON SiO₂ analyzer. The device automatically takes a water sample, adds the reagents in the correct order and quantity and measures the coloration photometrically.

Two measuring ranges are available: Low Range (0.02-10 mg/l) for the trace range and High Range (10-150 mg/l) for higher concentrations.

What is the carbonate value measured for?

The carbonate value (also known as the temporal value) describes the proportion of the water value that is caused by hydrogen carbonate ions (HCO₃-). Monitoring carbonate levels is crucial in many areas of water treatment:

• Cooling water systems: The carbonate values directly influence the lime-carbonic acid balance. Excessive values lead to lime precipitation in cooling towers and heat exchangers.
• Boiler feed water: Hydrogen carbonate decomposes to carbonate and CO₂ during heating, which leads to corrosion in the steam/condensate system.
• Swimming pool and bathing water: The carbonate value is an important parameter for the water balance according to Langelier or the LSI index.
• Drinking water: The carbonate content influences the taste and the tendency for limescale formation in pipes.

How does the Reagent work?

The C25 Reagents are liquid color reagents for fully automatic water analysis with SYCON analyzers. The SYCON device automatically takes a water sample, precisely doses the Reagent and measures the resulting coloration photometrically.

Depending on the device mode, the system operates as a limit value monitor (SYCON 2602) or as a measuring range device (SYCON 2702, 2802) with continuous measured value output.

Why is certified hardness monitoring required in the boiler house?

Steam boiler systems place the highest demands on the quality of the feed water. Even the smallest amounts of residual hardness can lead to limescale deposits on the heating surfaces – resulting in overheating, loss of performance and, in the worst case, boiler damage. VdTÜV Code of Practice WÜV 100 therefore requires continuous, automated monitoring of water hardness using certified devices – including the option of 72-hour unattended operation (BOB).

What is the SYCON BoB?

The SYCON BoB from RLS Wacon is a fully automatic online analyzer for monitoring the residual hardness in boiler feed water and returning condensate. It is certified in accordance with VdTÜV data sheet WÜV 100 and therefore fulfills the requirement for operation without supervision (BOB) for 72 hours.

The device is based on the proven SYCON platform, but is specially optimized for use in steam boilers: Pre-configured relays, an access code to protect against incorrect parameterization, a BOB probe for level monitoring of the Reagent and a shortened maintenance interval ensure maximum operational reliability.

How does the SYCON BoB work?

The SYCON BoB works according to the colorimetric titration method. A water sample is automatically fed into the measuring chamber and the Reagent (H25-0.05 or H25-0.1) is added step by step. An optical sensor detects the color change and calculates the residual hardness of the water.

The integrated BOB sensor continuously monitors the fill level of the indicator bottle. As soon as the remaining content is sufficient for less than 72 hours of operation (approx. 12 % fill level), a BOB message is issued via relay 2 and the display. This ensures that the indicator supply is replenished in good time.

The analysis time is approx. 3 minutes with an indicator consumption of only 0.05 ml per analysis. Up to 10,000 analyses are possible with a 500 ml bottle.
