Why is the total hardness measured with LHV?

The LHV series has been specially developed for total hardness measurement with analyzers from the LIMES series. The LIMES devices work purely as limit value monitors and continuously monitor whether a defined hardness limit value is exceeded or not reached.

Typical areas of application:

• Softening systems: Monitoring of the drain water after ion exchangers – immediate detection of resin breakthroughs.
• Boiler feed water: Ensure that the required residual hardness is maintained in order to avoid limescale deposits.
• Reverse osmosis systems: Continuous control of the permeate quality.
• Drinking water treatment: Automated quality assurance of water hardness.

The LIMES system offers a cost-effective solution for automatic hardness monitoring, which reliably issues an alarm as soon as a limit value is exceeded.

How does the Reagent work?

The LHV Reagents are liquid color reagents for automatic limit value monitoring with LIMES analyzers (LIMES Base, LIMES Plus). The device automatically takes a water sample, adds the Reagent and evaluates the color reaction.

In contrast to measuring range devices, the LIMES system does not provide exact measured values, but monitors whether the set limit value is adhered to. If the limit value is exceeded, an alarm is triggered – ideal for the reliable monitoring of water softening systems.

Advantages of the LHV series

• 4 limit value levels from 0.1 to 7 °dH

  Suitable sensitivity for different applications

• Specially developed for LIMES analyzers

  Optimum adjustment to the LIMES measuring principle

• Reliable limit value monitoring around the clock

  Less frequent indicator changes

• In-house production and individual batch calibration

  Consistently high quality – Made in Germany

• 24 months shelf life from production

  Cost-efficient stockpiling

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.

What is the p-value measured for?

The p-value (also acid capacity up to pH 8.2 or m-value/alkalinity) describes the concentration of hydroxide and carbonate ions in the water. It is a decisive parameter in boiler water and cooling water chemistry:

• Boiler water: The p-value is a key parameter for correct alkalization. Too low values lead to corrosion, too high values can cause foaming and overflow problems.
• Steam and condensate systems: Monitoring the p-value ensures that the alkalization remains in the optimum range.
• Cooling water systems: The p-value influences the corrosion and limescale separation behavior.
• Industrial process water: control of water chemistry in closed circuits.

How does the Reagent work?

The P25 Reagents are liquid color reagents for fully automated p-value determination with the SYCON P analyzer. The device automatically takes a water sample, precisely doses the Reagent and measures the resulting coloration photometrically.

What is iron measured for?

Iron (Fe) is one of the most common elements in water and can be of natural origin or enter the water through corrosion of pipes. Monitoring the iron concentration is essential in many areas:

• Drinking water treatment: The limit value for drinking water is 0.2 mg/l Fe (Drinking Water Ordinance). Elevated iron levels lead to undesirable discoloration and a metallic taste.
• Boiler feed water: Iron causes deposits in boilers and steam systems, which can lead to corrosion damage.
• Cooling water: Iron deposits reduce the heat transfer capacity and clog pipes.
• Waterworks: monitoring of iron removal – checking whether iron filters are working properly.

How does the Reagent work?

The Fe Reagents are liquid color reagents for fully automatic iron determination with the SYCON Fe analyzer. The device automatically takes a water sample, adds the Reagent and measures the coloration photometrically.

Two measuring ranges are available: The LRS (Low Range) Reagent for low concentrations (0.01-0.5 mg/l) and the HRS (High Range) Reagent for higher concentrations (0.2-6.0 mg/l).

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.

What is the total value measured for?

The total hardness (also water hardness) describes the concentration of alkaline earth ions dissolved in the water, in particular calcium and magnesium. Reliable hardness measurement is indispensable in many areas of water treatment:

• Boiler feed water and steam generation: Even small residues lead to limescale deposits (scaling), which can impair the heat transfer and cause damage to the system.
• Ion exchanger monitoring: Precise hardness measurement enables early detection of resin breakthroughs and needs-based regeneration.
• Reverse osmosis systems: Continuous control of permeate quality to protect downstream processes.
• Cooling water systems: Prevention of deposits and corrosion in cooling towers and heat exchangers.
• Drinking and process water: Monitoring of water quality in accordance with operational specifications.

In industrial water treatment, precise and continuous monitoring of residual hardness is crucial for safe, efficient and economical plant operation.

How does the Reagent work?

The H25 Reagents are liquid color reagents for fully automatic water analysis with analyzers of the SYCON series from RLS Wacon. The measuring principle is based on a colorimetric reaction:

The analyzer automatically takes a water sample at freely configurable intervals, precisely doses the Reagent and measures the resulting coloration photometrically. The color intensity is directly proportional to the concentration of hardness in the water.
