Measuring water quantity and quality in surface water (open channels, rivers, reservoirs, lakes, and estuaries) is one of the foundations of hydrological monitoring and has been a focus of OTT Hydromet since its first water current meters were designed in 1875.
Measurement of water quality in coastal regions and estuaries is critical in the characterization of hypoxic ‘dead zones’ as a result of nutrient loading and algal blooms in the water bodies. Sediment loading analysis through turbidity measurement is also important for coastal trend identification and modeling. Hydrolab and Sea-bird Coastal offer a variety of multiparameter water quality instrumentation and nutrient sensors for long-term coastal applications.

Our solutions for municipal water...
Measuring groundwater level or depth-to-water is critically important for identifying long term trends, including declining water levels, saltwater intrusion, seasonal variations, aquifer recharge, artificial aquifer storage and recovery, and level status for drinking water. Receiving groundwater data via remote data transmission from one of the many OTT telemetry options available saves time and resources spent in the field.
Urban Hydrology deals with the specific aspects of the hydrological cycle in urban and industrial settings. This includes all natural water flows as well as the consideration of precipitation, storm water, groundwater, rivers, and lakes, but also the infrastructure and systems for water supply and sanitation in a city.
In the marine market, ocean-going vessels and fresh water or inner coastal boats require water treatment technologies to meet drinking water, process water and wastewater requirements. Offshore oil and gas operations and ocean-going vessels generate sewage that can contain contaminants which have a detrimental effect on water quality and the overall marine environment. As a result, marine sewage treatment systems are required to lessen the environmental impact. The MEPC.227(64) effluent standards, adopted by the...
Reducing the risk of infection transmission. In a world where high-density living in urban areas is increasing, and healthcare and the spreading of pandemics are among top concerns, the role of the cleaning industry is of great importance, though often underestimated.
The surface finishing industry is driven to provide superior plated components, in turn requiring high quality anodes. De Nora DSA® anodes, with their tailored precious metal coating applied on Grade 1 titanium substrates, ensure durable, reliable and high performance operation.
Winning with electrode design to reduce energy costs in traditional processes and UAT Reverse Osmosis (RO) Membrane Filtration Systems to meet any tap or brackish application need. Nickel and cobalt production, precious metal refining (gold, silver), recovery of copper from bleed streams or valuable metals from industrial wastewater, are some of the applications of our titanium DSA anodes.
On going research and development using HNG technology in water treatment is showing how catalytic HNG can be in activating, sustaining and enhancing microbial interaction. HNG triggers an effective chain reaction that neutralize containments / pollutants. The introduction of HNG into water is showing nature’s power to regenerate, balance and clean, when approached in the right way. The HNG WaterLife and Seaver programs are in development for collaborative deployment. Areas of activity include Aquariums,...
When ships discharge their bilge water the maximum level of hydrocarbons in the water is regulated by various Environmental Protection Agencies, for example there is a limit of 15ppm enforced by the IMO (International Maritime Organisation) in all international waters. Companies breaching these limits are liable to significant fines. Further regulations have been introduced to control the use of bunker fuels. The Marine Environment Protection Committee (MEPC) of the IMO has approved proposed amendments to the...
Continuous monitoring of nutrient levels provides crucial information about daily, seasonal and event based changes in water quality conditions, and can be a strong indicator on the overall health of the water body. In recent years, monitoring of nutrients has grown in importance as it has come to the forefront in regulatory compliance of water quality in many regions.
In many fields of water treatment Körting ejectors are applied as gas introducing systems; Waste water aeration in aeration tanks and SBR-Plants. Introducing ozone or oxygen. Pressurised dissolved air flotation. Disinfection of potable water and de-acidification. Further applications are: Diluting and conveying acids and lye during the process of regenerating ion exchangers.
We are committed to providing mixed metal oxide (MMO)-coated anodes and electrochemical technologies for the electronics industry. Listening to the industrial needs and main drivers, we have developed a high quality and reliable MMO-coated titanium anode for the electrodeposition of copper, gold and other metals on printed circuit boards (PCB) in replacement of soluble anodes.
EDUR pumps have been used preferentially in municipal and industrial water supply and water treatment for decades. Traditionally the reasons are the sturdiness and the long service life of our pumps and the special capability of some models for transporting liquid-gas mixtures.
