Lenntech Water Treatment applications

Process water covers the wide range of boiler feed water, cooling water for heat exchangers or engine, chemicals dilution, etc. It should typically have a conductivity ranging from 0,1 to 50 uS/cm, with little to no hardness to avoid scaling in heating system. Oxygen and carbon dioxide should be removed to prevent corrosion. Depending on your application, the water quality requirements can vary: Boiler feed water characteristic. Cooling water quality. Tap water or fresh groundwater are the most widely used source of water to produce process water.

Drinking water can be produced from any natural sources like groundwater, lakes and rivers (surface waters) or seawater. Drinking water standards are set by the World Health organisation or by the European Union. Drinking water must be free of suspended solids, microorganisms and toxic chemicals. Mineral concentration recommendation vary from country to country but most of the minerals have a maximum concentration recommended to ensure safe, equilibrated and pleasant water to drink.

Agriculture is by far the largest water use at global level. Irrigation of agricultural lands accounted for 70% of the water used worldwide. In several developing countries, irrigation represents up to 95% of all water uses, and plays a major role in food production and food security. Future agricultural development strategies of most of these countries depend on the possibility to maintain, improve and expand irrigated agriculture.

Ultra pure water is mainly used in the semi conductor and pharmaceutical industry. Because of the continuing miniaturilisation in the semi conductor industry, the specifications become more strict every year. Ultra-pure water contains by definition only H20, and H+ and OH- ions in equilibrium. Therefore, ultrapure water conductivity is about 0,054 uS/cm at 25oC, also expressed as resistivity of 18,3 MOhm.

Lenntech can offer containerized drinking water system, skid mounted units and trailer built solutions to meet any local requirements for fast shipment and flexible application use in the most rural areas. Lenntech will be happy to assist any NGO* and other organisations operating in acute relief work in their immediate needs for emergency situations and natural disasters.

Water usage in agriculture and horticulture industry is mainly done through irrigation process. With global agricultural production increase and consequently increase of water demand there has been more and more need to look for water recycling options in order to decrease the water consumption at source. Lenntech provides sustainable complete solutions for water treatment in agriculture and horticulture industry considering a wide range of technologies and strategies.

Food and beverage producers are constantly looking for production optimization while achieving the highest levels of quality and compliance. Lenntech provides sustainable complete solutions for ingredient, water and waste water treatment in food and beverage industry considering a wide range of technologies and strategies.

Water is widely used in industry, whether it is encountered as raw water, process water or waste water. Very often this water must be treated before entering the process to ensure its quality and properties will meet the specifications demanded by the industrial process. In addition, with recent discharge regulations and policies towards zero liquid discharge, there is a high demand for solutions for recycling and reuse of waste water produced. Lenntech provides sustainable and complete solutions for water and waste water treatment for industrial water considering a wide range of technologies and strategies.

Micro-electronics industry is probably the fastest growing industry driven mainly by the expansion of the computer and telecommunications markets, as well as the growing automotive, military and industrial electronic markets. The production of smaller and smaller microelectronic components is contributing for a great pressure for the purification of process waters, given the extreme high quality water demanded by the manufacturers Lenntech provides complete solutions for ultra pure water production for semi-conductor industry considering a wide range of technologies and strategies, thoroughly selected according to the client specs.

Contaminated mine water is generated when rock containing sulphidic minerals is exposed to water and oxygen, resulting in the production of acidity and high concentrations of metals and sulphate in the water. Mine drainage, process water and storm water associated with industrial activities are the main types of water produced in mining operation. The two primary aims of the treatment of contaminated mine water are to neutralize acidity and removal metals. Lenntech provides sustainable complete water treatment solutions for mining industry considering a wide range of technologies and strategies.
