Groundwater Treatment | ||
|
VHE provides groundwater treatment services on almost every remediation project we undertake. In all cases, we carry out the design, construction and operation of the treatment facilities using in-house resources. We have significant experience of treating water arising from excavations or from within existing gas holder tanks contaminated with organics (LNAPLs and DNAPLs) and heavy metals. Prior to water being returned to the environment, it is treated using a combination of activated carbon filters, oil and water separators, sand filters and pre-setting tanks. Our skilled operators and supervisory staff ensure that groundwater treatment works adhere to our own environmental procedures and are carried out in accordance with pollution prevention guidelines. We have gained significant experience of groundwater treatment from our remediation term contract with National Grid, under which we have worked on more than 200 sites. During a remediation scheme at Beckton in London, VHE installed and operated a groundwater treatment system that treated some 100,000m3 of liquids. The plant - which consisted of activated carbon filters, an oil/water separator, sand filter and pre-setting tanks - had a capacity of 20m3/hour and enabled discharge of clean water to sewer.
