Percolate

Kemic Water Technology supplies remediation systems on a rental basis as well as permanent solutions for contaminated groundwater. Each system is designed for the issue at hand. Remediation solutions for contaminated water are usually the result of close collaboration between the Danish regional governments, utilities companies, consulting engineers, contractors, groundwater contractors and researchers in the field. 

Groundwater protection is a topical issue, receiving increasing attention, and Danish researchers are studying and monitoring this carefully. Monitoring groundwater aquifers sheds light on new traces of pesticide residue, solvents and other chemicals which slowly percolate through the soil strata. Remediation plants have already been established in many locations and, since experts believe we have not yet seen the whole extent of the contamination, it is expected that these will be in service for a long time to come.

Design based on client preferences

Kemic Water Technology supplies remediation systems for boreholes, building sites and other areas with contaminated water. The systems are available as a stand-alone solution or a container solution. Each system is designed based on the client’s requirement for water treatment. Requirements may differ depending on whether the water is discharged to a recipient, recycled or discharged for other production needs.

Close cooperation with regions and research institutes

The degree of contamination and the environmental requirements may vary. Therefor, issues are solved in close collaboration with the Danish regional governments and research institutions to ensure the best possible solution.

Different types of contamination are listed below

Contamination with solvents

Solvents in the groundwater can vary in nature. A Kemic Water Technology activated carbon filter system or vacuum extraction system can be used to eliminate solvents from the groundwater. 

A vacuum extraction system is an environmentally friendly method for treating contaminated water by means of a range of processes. Read more about Vacuum Extraction Systems.

An activated carbon filter system is a recognised method for removing various unwanted elements or contaminants from the water. An activated carbon filter system requires a permit from the authorities. Read more about  Activated Carbon Filter Systems.

Contamination with Vinyl Chloride

Vinyl Chloride can be eliminated using a Kemic Water Technology vacuum extraction system. This is an environmentally friendly process which removes solvents as well as petrol and oil components. The treatment method consists of several processes, whereby the contaminated particles are gasified in a vacuum, and, after buffing, the resulting water quality fully complies with the threshold values for discharge of water.

Contamination with firefighting foams

Firefighting foams are eliminated using an activated carbon filter system.

Kemic Water Technology specialises in removing such foams from water. This is usually done using remediation systems since the firefighting foam percolates into the subsoil in a limited area or is collected in an oil separator filter. This type of remediation system is set up at the client, either as a stand-alone system or in a container. Kemic Water Technology will handle operations of the systems to ensure optimal operation of the filters.

Contamination with pesticides and BAM

Pesticides and BAM are eliminated using an activated carbon filter system.

Problems with pesticides and BAM are usually solved by mixing water from several boreholes to comply with threshold values for discharge of water to consumers. However, in som cases, the contamination is so extensive that it cannot be managed without additional water treatment.

Kemic Water Technology is working on a development project which, in the future, will be able to remove pesticides using natural processes. Read more about The Trojan Horse. 

Contamination with Chloridazon and Desphenyl-chloridazon

An activated carbon filter system is used to eliminate Chloridazon and Desphenyl-chloridazon.

In 2017, attention was firmly focused on Chloridazon and Desphenyl-chloridazon in boreholes at Danish waterworks. Chloridaxon can be eliminated from water using an activated carbon filter system. The first system for eliminating Chloridazon is already in use.

Contamination with pressure impregnation fluid, Tributyltin

Tributyltin is removed in a filtration plant with a special filtering medium and a specially manufactured oil separator.

Tributyltin is found in concentrated areas where wood was previously pressure-impregnated. Read more about Tributyltin. 

Lead contamination

Lead is eliminated from drinking water or percolate in a filtration plant using a special filtering medium and, in some cases, iron granulate.

It is rare to find lead in drinking water in Denmark but there are many remediation boreholes with water containing lead. Kemic Water Technology supplies a filtration plant for removing lead from percolate. The filters consist of pressure filter system with special filtering material, which absorbs the lead in the water. The result is a concentrated waste product, which must be transported to a landfill site.

Zinc contamination

Zinc is eliminated from drinking water or percolate in a filtration plant using a special filtering medium.

Zinc is found i percolate in large Danish cities and in areas with a concentration of heavy industry. Zinc can be effectively eliminated using a filtration plant and a special filtering medium. The result is a concentrated waste product, which must be transported to a landfill site.

Chrome contamination

Chrome is eliminated from drinking water or percolate in a filtration plant using a special filtering medium.

Chrome is found in percolate in large Danish cities and in areas with a concentration of heavy industry and landfill sites for industrial wast. Chrome can be effectively eliminated using a filtration plant with special filtering materials. The result is a concentrated waste product, which must be transported to a landfill site.

Mercury contamination

Mercury is eliminated from drinking water and percolate using a filtration plant combined with special filtering materials.

Mercury is found in percolate in large Danish cities and in areas with a concentration of heavy industry. Mercury can be effectively eliminated using an activated carbon filter system with special filtering materials. The result is a concentrated waste product, which must be transported to a landfill site.

Nickel contamination

Nickel is eliminated from drinking water or percolate using a filtration plant with special filtering materials.

Nickel is found in percolate in large Danish cities and in areas with a concentration of heavy industry. Nickel can be effectively eliminated using a filtration plant with special filtering materials. The result is a concentrated wast product, which must be transported to a landfill site
