HARDNESS AND ALKALINITY ANALYSERS

To maintain the delicate balance between scale formation and corrosion, it is important to measure and know the hardness levels of process water, so it is important to monitor calcium and magnesium levels separately, along with total hardness.

On the other hand, the control of water alkalinity is an important factor in a wide range of applications, from drinking water and beverages to wastewater treatment, boiler water, cooling and many other types of chemical production and manufacturing.

SP510 Monitor

Hardness analysis

Hardness monitor designed for continuous monitoring of water systems. Alarms when the total hardness exceeds the preset limit. Can set up an automatic water softener regeneration system.

AMMONIA AND AMMONIUM ANALYZERS

Ammonia (NH3) is often found in groundwater due to microbiological processes, but its presence in surface water is often an indication of domestic pollution. Its relationship to ammonium (NH4+) is directly related to pH levels and its monitoring is essential in areas such as watersheds, chlorination disinfection in drinking water treatment, nitrification and denitrification processes in wastewater or in the pharmaceutical industry.

TOC, TOTAL NITROGEN AND PHOSPHORUS ANALYZERS

Total Organic Carbon (TOC) in high concentrations can have a significant impact on ecosystems and damage unmonitored equipment.

Excess of nitrogen in the form of ammonia or nitrate can pose a risk to public health, and ammonia in high concentrations and at high pH can be toxic to sludge-digesting microbes.

High levels of phosphates in the catchment can accelerate the growth of various types of algae and plants, leading to eutrophication.

BioTector

TOC Analyzer

TOTAL AND DISSOLVED SOLIDS PROBES AND SENSORS

High levels of Total Suspended Solids (TSS) can affect the performance of filtration systems, critical equipment and piping systems. Total Dissolved Solids (TDS) can come from natural sources, urban runoff, municipal and industrial wastes, and chemicals used in water treatment, and their monitoring is essential as an indicator of water quality.

Solitax sc

Turbidity and suspended solids

Digital process probes designed to accurately measure turbidity and suspended solids. They include submersible or inline turbidity and solids probes in stainless steel or plastic housings and with or without self-cleaning features.
