Product Overview:
MEC uses metal hydroxide flocculation produced by soluble metal anode during electrolytic process to remove contaminant
such like SS, COD, heavy metal, bacteria, etc. MEC is mainly applied to all kinds of oil-gas field sewage treatment, especially
the flow-back fluid produced in the process of fracturing, acidification, well repair and well flushing, etc., to achieve standard
recycling.
Principle of MEC
Electrocoagulation is a process utilizing “sacrificed” anodes to form active coagulants which are used to remove pollutants by
precipitation and flotation in-situ.

2)Treatment of produced water
3)Treatment of Drilling Wastewater
Technical Features:
1)Wide adaption range: it can adjust the operating parameter according to inlet water quality;
2) Structure process optimization: it can save more power compared with traditional electrolytic technology;
3) Compact structure, small footprint, skid package, vehicle-mounted multipoint service;
4) Small output of sludge: only 1/3 sludge of traditional chemical coagulation process
5) Strong capacity of resisting impact load;
6) Self-R&D technology by Veritas-MSI, no worries for consumables and technology services.
Application Example:
MEC(Mobile Electrocoagulation System) applied in Jiaoshi Town, Fuling, Chongqing
